My 250 Sport has the jet kit, and the 14 tooth sprocket, and it will do 50 mph. That is with a 130lb. 15 year old riding it. Oh, and that is with 22" rear tires.</end quote></div>

Thanks for the input 00XJ, i was just estimating. Have you clocked your sons 250 at 50 mph?

I knew you were a kid jetmotoracer, i was referencing my childrens age in the other post to let you know I have kids.

Getting a job at a motorsports shop is a great idea!! And reading a lot of the stuff here will help you too. going to a larger front sprocket would only make things worse than they are now. Your bicycle must have been geared so that it needed more top speed than take off speed.

 

it makes it harder to start butyou peddle less in reffrence you would basicly be doing less rpms......but you still go fast

 

and about getting a job at a mooter sports shop i still have a few years till i can get one.....good thing is i live right next to one

Its just like the gearing you have on your quad. Hard to get started but goes fast once moving.

I used to hang out at my local Yamaha dealer when i was about your age. i must have drove the guys that worked there crazy I was there so much. [img]i/expressions/face-icon-small-smile.gif[/img]

 

im not there much but i always ask the guys questoin

 

you know what sucks!!!!!!!!!! me and my freind were gunna hace a sat threw mon ridin jam session but the bearin some were in the kick starter broke and its stuck in rev.... its relly old to

 

Yeah, I'm unsure how much drag is on dynos, but they definately have some or the engine would over rev too quickly.

I really can't wait to get my dad on one of these. It's gonna be pretty funny watching him try to keep getting dirty. =)
