OK Athis, since you are ready and willing to listen to other peoples opinions and keep an open mind, (good for you), I have a friend of mine that has a Polaris Sportsman 500HO quad. My mildy modified Ody will smoke his 500 effortlessly. Top speed of the Polaris 500HO is around 53MPH maxed out.
Now the Polaris Sportsman I believe is around 100 pounds heavier at around 695 pounds.
I have no clue as to the gear ratio of the Polaris and this might be the factor as why it is so much slower. Just my 2 cents worth.....Rand
I'm all eyes in this case :P haha. But seriously great points! I'm just trail riding...no racing or anything like that. Having said that, I do enjoy and still want the power to spin the rear wheels and get the back end to drift. Top end doesn't concern me honestly..I can't imagine rolling in an Ody at 53 mph.

This is my buddies son's buggy. It has a 2000 Sportsman 500
Engine in it. Scrambler 3:1 FNR box, 3:1 chain reduction, 25" tall tire.
Ok...excellent info and thank you for the video! But help me out a little...."Scrambler 3:1 FNR box, 3:1 chain reduction" <---- you mean it is not using the Ody stock Tranny?

Great running little Engine. For the most part, for the trail riding that we do, it works good. But he has to push it pretty hard to keep-up. It will turn 7000rpm, but it is not making any power up there. It pulls good at 5500-6000. Might do 50mph on a hard flat run but takes a while to get there. If speed and power is the goal... maybe not the best choice. Depending on the type of riding you do, I'd be concerned that the extra reduction of the Ody gearbox is going to keep this Engine above optimum rpm. Your clutching is going to need some good overdrive to keep some load on the Engine.
I suppose describing my "ideal" driving style may help. Like I mentioned to Radman, I'm just trail riding...no racing or anything like that. Having said that, I do enjoy and still want the power to spin the rear wheels and get the Ody to break the back end and drift. I would like a good response to throttling in the 20-40 mph range. Top end doesn't concern me as much honestly....I can't imagine rolling in an Ody at 53 mph.

As far as the carb mount, it'll work. As far as the oiling, I too think you have a problem standing it up that far. The oil pump pick-up can't be above the bottom of the crank. The crank can't be splashing the oil around.
Agreed...I'm going to look at this seriously before I decide anything.

You need to match the RPM if you want the same top speed without a gearing change.
A 4 stroke Engine only makes a POWER STROKE every other rotation of the crank shaft a 2 stroke Engine makes a POWER STROKE every rotation of the crank shaft
A 2 stroke turning 7000 RPM is making two times as many power strokes as a 4 stroke Engine is at 7000 RPM
2 stroke 7000 RPM = 7000 power strokes
4 stroke 7000 RPM = 3500 power strokes
Hoser, how do you think it would affect the range of riding I describe to DaveM?
