Here are two FL350 port maps the first one is TurboTexas stock ported cylinder.

The question is how wide do you or can you safely go on the exhaust? Every 2 stroke Engine I have ever hoserized I have widened the exhaust port and it was all win win, no ill side affects, all gains every time keep in mine I don't take things to the extreme either too big of a hole and you end up with short lived or damaged rings.

Its just a port map of the cylinder, the top of the sheet is the top of the cylinder.

MacDizzy has plenty of info and a nice write up http://www.macdizzy.com/cyl_primer.htm

Happy reading.

My exhaust port is very wide compared to stock. Its also eybrowed out very close to the side intake ports. Next time I have it apart ill map it out and post it up. Its very conservative compared to the original lekich porting its modeled after. You can ask Nickrnr my sons 350 is stupid fast and very reliable

Please do.

I gotta look at the piston make sure the reliefs they machine into the sides of the piston wont be into the eye brows this is a problem on the CR500 and why you can only use a wiseco on them if the exhaust is modified the stock pistons or prox will link the exhaust and transfers with the relief cuts.

The newest wisecos should not be a problem they no longer machine them out.

ok I thought the 95% was of the piston size? 78.5 x .95%=74.575
is that how you came up with the 74mm?

Turbo, Yep it's how you do it. Just remember around the wall not across unless you use a demand factor. The way "H" layed out on sticky note nd then applied is a great idea and one I will adopt. Thanks "H". One thing to keep in mind is that the port get larger as you increase bore. You can always grind out material but harder to put back. As the ports get larger the distance between them get shorter. This must be factored in on a stock bore. The .25 and .50 over ok when you get bigger it changes the math big time. To say port a 80mm and take it to 82 and it does change things. I tried to post up some stuff but are experiencing technical difficulties. Half the text is not enough to explain better. The topic was on R-1,R-2 and R-3 of the exhaust port and the angles related to short cycling between the main transfers and the exhaust port. The mean time area math is a lot harder than just time area.

Sorry.

Well gota load for the lake after a good night of parting at the house and night riding. Tube + hangover = fun time at lake.

Turbo/"H", I did some number crunching on Turbos port map. I know his cylinder is already done however wanted to do some math on it any way for future builds as well as log his info into my data base. Going off of the picture and the numbers on the pic and then factoring in the data I have for the 350 on deck heights base gaskets head gaskets ect I come up with a base line.
EX port open: 92 degrees ATDC
Duration: 176 degrees ( 360-92-92= 176)
Mean Area line: 44 degrees BBDC ( (180-92)/2= 44)
Single EX port Mean Area: 558 mm^2
Exhaust Port Total mean port area: 1116 mm^2 or 11.6 cm^2( 1116/100=11.6)
Displacment of 350.40 cc's or cm^3 ( side note: if one looks at a pilot cylinder it stamped cm3 by the intake)
cm^2/cm^3= 11.6/350.40= .0318493
Angle Area of 5.6054768 ( duration x cm^2/cm^3) ( 176 x .0318493=5.6054768)
RPM Range: 5000 to 7500 ( based on angle area-deg cm^2/cm^3 .00011 to .00018)
Peak Power PRM: 6200 to 6700 ( based on sec,cm^2/cm^3, port time mean area range of .00014 to .00015)
(T) for 6200 rpm = .0001506 ( 176/(6200x6)= 176/37200=.0047311 x (cm^2/cm^3 or .0318493)=.001506
(T) for 6700 rpm = .0001394( Same math as above )
Out of space, more later.

Hey Hoser or Adnoh, I am going to pull the 420 jug off here real soon. Would you be interested in me mailing it to either one of you to port map? May be some info there to share with everyone.

Um, Nukems 420 cylinder. That would be a great tech post. The maping is pretty easy as "H" has shown. A piece of paper in the cylinder and a pencle. It does take some practice to get them to look as good as his though. Since your bore is so large and over square with a different type of piston the cylinder will not tell the whole story. I would bet your cylinder has been altered for the piston. The skirt of the piston alone will have an effect as well as the pin location. If the rod lenght and stroke is stock than the piston pin location will change the numbers. This changes the point to which the port open and the duration which changes the mean line for the mean area calculation. Base line numbers are based on cylinder maping however the piston and piston number can have an effect yes slight one for most stock and after market piston for that perticular Engine. Now change that type and brand and thing may get interesting. The bottom end cylinder and head would be required to to get it pretty close as well as all gaskets, spacers ect. The photo documation and measuring can be done by you and post the info for sharing. Then we can take the numbers and get the results or you can use simple math to comput yourself. I would bet you can handle the math from your military back ground. Using a basic degree wheel will get you close when you back it up with cylinder map numbers. To be real accurate the basic degree wheel will not read tight enough numbers. Not a big deal for some one like myself I factor in percentages as not to go past the limits for the degrees 1 degree varible in enough.

(Contiunation) As far and (T) and angle ares at rpms the spreed sheet can supply one with a range in area and time as well as proposed changes. Once the area in width has meet the limits then the port will need to go up which increases area as well however also effeect (T) which is the math is based off of duration and rpm. Another thing to consider here is as you raise the port increasing duration ( port open time)the mean line area is also becomes lower and the % of port open increases. If you look and the mean line calculation it based off of duration as the varible. So before you raise of widen the port a base line number is required to see where the sec-/cm^2/cm^3 and angle area falls . If you want the Engine to preform at a certian rpm range and/or in tune with the pipe crankcase pressures ect one would need to know first where its at, then adjust the ports to fall with in that range. If one takes the width out the oval get larger and this will increse area. If one takes the port taller oval gets taller which increases time and area. The time increase is the longer the port is open at a given rpm which is th e( sec) of the time area formula. The approach "H" takes is a good one for broad range torgue with only a slight effect on peak power. For our type of bikes that's a good choice for the pipes available. One need to ask what parts we bolted up to our machines. Most will say a clutch pipe reeds carbs air mod. It does not take long to see a corlation. First the clutch. The engagement speed of the clutch loading the Engine has just been bumped up so do we need the low end time area number to increase accordingly. Has one now changed the Engine rpms operating range. Does one need the lower time area to remain for the freewheeling eninge with out load. So increasing area ( width) is a great first step for the area angle which increases up the rpm scale

(continuation) What about the pipe( expansion chamber). What it's doing to the Engine beside making it louder in db's. Without a very lengthy discussion basically it changes the pressure waves pushing and pulling flow rates ects. Usually we have two choices rev and torque, two different times effecting flow rate. The based of the tune of the Engine. One has to wonder did they design these just off of the numbers or did they tune them with certain bolt on parts in mind. You kinda get the idea of where I'm going and the relationship. If we look at the formula for Lt ( tuned length in inches the variables are port open in degrees and crank shaft speed in prm ( revolution per minute). I also like to factor in port area and inlet area and there ratios save that for another day. The other thing to consider is the pressure wave speed and what influences that speed. In short it's very fast, the temperature of the gas will have an effect on flow or EGT ( exhaust gas temp). If the gas is cool the speed is slower and if its hotter is flow quicker. Both of these will have an effect on the pressure wave and its time which will have an effect on tune. If the return wave is late the ex port is closed you loose the stuffing effect of the raw fuel being pulled into the inlet which by the way is a cooler gas so it slows down. If it returns to soon than the you would have a cylinder pressure loss from the port still being open at the end of the pressure cycle. So where do we want the Engine to be dirty and at what rpm do we want the Engine to run efficiently and how can increase the rpm range of efficiently with out greatly sacraficing relibality. The gloden rule is piston speed of 4000 ft/min. Dang more math, I belive when these numbers were established the pistons were much heiver than todays pistons and the quality of todays piston can eceed this number. I'm not saying its a good idea and the number of 4000 is one that should be used. I do believe the ody has a shorter stroke than a pilot and the rpm can be increased accordingly. Gota go lay some concrete more later.

"H"/Redskinman/ others, I been working on his numbers and was wondering if any one had a deck height number for his cylinder. With the resleave of the cylinder I was needing to confirm a few facts about his cylinder numbers.

Send it to Adnoh let him do a full CSI and reverse engineer on it he is much better with the numbers than I am and seems to have a really high attention to detail, it would be nice to have those cylinders duplicated I bet the displacement could also be increased.

Wonder what it would cost to have some of them cylinders cast then let speedchaser install the sleeves and make a cool head like he made for the Pilots?

It would be a expensive mod but one hell of a upgrade once your Honda cylinder was all used up.

I did some numbers on Redskinmans map. There is a slight issue in the calculations however this should be ok for a comparison of the exhaust numbers. On Redskinmans ex-port it has been raised with radius changes and the width pretty close to the same as Turbo's. The width is bore sensitive, Redskinmans exhaust port has a time and area difference than Turbos mostly Time. This changes the sec in the sec-cm^2'cm^2 calculation the most as the area is increased by it's height crater than its width. As a side not I have seen that the sleeves installed have a greater time area than stock both for the pilot and the 350. Any way here is the comparison numbers for Redskinmans base line
EX port open: 86.5 degrees ATDC, Duration: 187 degrees, Mean Area line: 47 degrees BBDC
Single EX port Mean Area: 711 mm^2, Exhaust Port Total mean port area: 1422 mm^2 or 14.22 cm^2
Displacement of 346.09 cc's or cm^3
cm^2/cm^3= .0410875
Angle Area of 7.6833625
RPM Range: 6800 to 10300 (based on angle area-deg cm^2/cm^3 .00011 to .00018)
Peak Power PRM: 8500 to 9200 (based on sec,cm^2/cm^3, port time mean area range of .00014 to .00015)
(T) for 8500 rpm = .0001507
(T) for 9200 rpm = .0001392
Once these are compared to the transfer /intake angle areas it will make a guy go UM. It will most likely show loss of broad range torque. Once all the numbers are achieved this could be a good example of too much time (port open to high to much duration) and not enough area (port chord width) for the stroke. You can see how the bore sensitive will have an effect as the bore get larger. Area increases and time remains and the mean area increases but at a smaller rate than the transfer and intake.
This is one reason I have a concern with the deck height number as well as the CR ( increase in Cr to get some torque back)and the stock ign timing. If my thoughts are correct the Egts will run higher and require a much fatter air to fuel ratio hurting mid range power or lead to top end lean out as heat builds.

I will go back and re run the numbers to be sure the mean area/duration is correct. This cylinder may need its base turned down and a thicker head gasket used.

Redskinman,since you do not have it installed would you measure me the transfer port opening from the bottom of the port to the top. "H" map called out .637 inches or 16.17 mm then check the opening from the top of deck to transfer port roof opening. Then measure top of deck to top of ex opening. Then I can rework the math off of 68 mm stroke and get approximate deck clearance based on what base gasket your using. By the way what gasket thickness you got. If you want to have some fun you can install the piston in the jug (no rings) and turn it upside down with the deck laying flat on a table and piston install orantated corectly ( intake to intake) and snap a pic looking down the cylinder from the base. Then measure down from the bottom of the cylinder to bottom of the skirt in a vertical line of the exhaust port using the end of your caliper. Then turn it upside right with the base laying flat on the table and snap a pic and mearure down to the crown from the deck

Thanks Adnoh.

Redskinman,since you do not have it installed would you measure me the transfer port opening from the bottom of the port to the top. "H" map called out .637 inches or 16.17 mm then check the opening from the top of deck to transfer port roof opening. Then measure top of deck to top of ex opening. Then I can rework the math off of 68 mm stroke and get approximate deck clearance based on what base gasket your using. By the way what gasket thickness you got. If you want to have some fun you can install the piston in the jug (no rings) and turn it upside down with the deck laying flat on a table and piston install orantated corectly ( intake to intake) and snap a pic looking down the cylinder from the base. Then measure down from the bottom of the cylinder to bottom of the skirt in a vertical line of the exhaust port using the end of your caliper. Then turn it upside right with the base laying flat on the table and snap a pic and mearure down to the crown from the deck

Thanks Adnoh.

most of what you said is all jibberish to me,not sure exactly what you want me to measure.I will need pics and detailed instructions.I am off wed and can check it out then if you can tell me better what to do.I don't have any gaskets for it,this is a backup on the shelf for when I do need it
