On the decked cylinder was he using the 85 or 88 head gasket.

The 88,89 is thicker than 85. The old trick for the 88's was to get an 85 head gasket and bump comp or double the base gasket and use an 85 with reed spacer and rev pipe changeing port iming to top end. When the old 85 had to be deck a couple of times the 88 was used as a quick fix as not to cut and reshape head after decking. I have seen after some rebuilds where the 85 was used on a decked 85 it smacked the head or blowing head gaskets and they just keep rebuilding it untill it took out the crank or gernaded the case. If the conter balance area has a bolt head broke look close at the crank and counter balancer bearings it tends be an indacator of something bad happened. If the top grove in the ring area is smashed that also is a good indacater as well check diff from top and bottom ring end gap. may have a pressure problem takeing top ring out prematuraly. See if the rings were put on right first, that one miss lead me once and chased the wear the wrong way. That was a big smack on the back of my head, I over look the basics. That one got wrote down in big letters in the note book.

(I installed a Dial A jet and I'm not happy with it at all.)I think I'm going to try that carb you sold to me on it.

I love my Dial a jet... I am not trying to be a smart ash but once you get your carb dialed in... Then add the dial a jet... Some have just installed the dial a jet on a new carb... I believe once you have your jetting like you want it, then you install the daj and drop 2 jet sizes on the main... I used mine today... Last serious riding was a few weeks back and in AZ, and today here in South Texas it was a miserably hot and humid day... I went one size smaller on the dial (less air) and felt comfortable with that... I am still no expert, but this thing gives me a better feeling on my jetting....
How is yours not working for you???

Can I chime in for a second?.... Sounds like a spark plug going bad. I have had alot of them do that exactly. Install a new one then give it another try.

The main trouble was mounting the adjuster block, you know the 1 with the zip tie method, theres really not a whole lot of room on the 250r air inlet to the box for it, it was a very tight install, plus the darn thing not running didn't help well at all.Your running your on the 350 correct?Nuke em will tell you theres not a whole heck of a lot of room from the carb outward, I wish I could take a picture of it, I will post for you to see.I couldnt use the other mounting sytle due to the bowl on the stock PE 38, it doesnt have a drain on it to insert the other piece-hope I am expalining it well here.I am totally open for ideas here on an install on it, I paid like hundred bucks for the darn thing-

I sure can get some pictures, I removed the old air inlet tube so I can show you where I installed it-I had to drill the hole in the drain plug as well for my fitting, could seal it right from day 1-you had to drill your carb, do you have a Picture by chance of where you drilled it by chance?

Got my new DURABLE antifade nut from ROCKY MTN and walla-fits like a glove on my LONESTAR AXLE-son of a bitch-ordered it for a 86-89 trx250r LONESTAR told me it wouldn't fit-losers-LOL!!
I installed the hub, new rear caliper and fresh plug, the thing after warming up is a rocket, I was so happy , runs like I stole it!!!!!-needs final jetting and some tuning for low end throttle response but otherwise runs great.

Nuke-em your right.I spent like 4 hrs on it last night, checking the stator, key way, wire harness, replaced the coil, measured OHMS and resisiteance, and finally came onto the trouble,

BAD KILL SWITCH-YUP the simpliest thing was the issue-I had purchased a OEM switch off Ebay when I bought the thing,so after a little quick fix cause the ends didnt match from old to new I plugged it and BAM, spark!!
yipee-then grrrrrrrr-kick kick kick no spark, check everything again.Nothing.I told myself, watch this bet that plug is bad, sure as a pig loves mud, put fresh 1 in br8es and walla licked over on first kick idesl great-I am in heaven finally
It still needs to be adjusted and the lock nut installed-long story there-but it runs great.

Hoser, Fed has completed about 8 DVDs. I need to get everyones addresses for shipping. I have Dennis's, Jerry's and I think yours.

Thanks! I got one right, a blind squirrel finds a nut now and again...LOL.

funny, I am looking at Durablue and Lonestar axles w/anti fade nuts for my trike too. I just picked up a used Lonestar double roller carrier and bearings for $45 on Ebay. SCORE! I let my stocker's bearings go too long and ruined the carrier. That will teach me. Any tips on which axle or interchangability (400ex,300ex,250R). There is a guy on 3WheelerWorld selling a very nice round tube +2 swinger, if you are interested.

See picture I added some arrows to...
If you have yours where I think you do it should be ok as long it is above 9 oclock position... I have mine on the stock fuel tank side of the ODY at about 10:30 oclock...
What is it doing or not doing that is not right???

mine is actually closer to the airbox, where the band clamp is at... I will try putting mine further back on my next carb...

HUH?

You have pics I don't get it.

Correct me if I am wrong but this needs to be mounted as close to the venturi as possible for the best carb signal, gas comes out the little rod that sticks into the air flow, the fuel needs to be atomized so it will burn correctly, you don't just want gas dribbling into the Engine.
