who has had this done and what kind of difference did it make and do u like it? scott

 

i have it on my 400 and it is .5 pounds lighter tha recomened and i haven had any problems thething revs lie a 2 stroke should(to the moon) i also did this to my friends tb and it woke it right up.

 

I've had the race lightening done to my flywheel and its a night and day difference.
A lot better throttle responce!

 

is it jsut throttle repsonse or is there better acceleration also? easier wheelies?

 

The thing revs out alot faster. Wheelies are easier because it revs faster.
Its like if you had a rubber ban powered air plane and only wind it 10 times
and now you wind it 20 times. It accelerates faster!

 

sounds like thats what i need!!!

 

sounds like u need to remove some weight if it already doesnt accerlate fast

Now that you brought up the weight thing. I think that the Polaris claims on the TBs
weight is off. I just weighed my bike with a 440 lb hanging scale and with all the stuff
that I have removed it weighs 420 lbs with just 1/8 tank of gas. Polaris claims that a
99 TB 250s dry weight is 440 lbs and I know that I have remove 50 pounds of stuff.
The scale is correct so I figure that my TB was really about 470 lbs. Has anybody
else came to this conclusion?

 

tbsleeper it already accelerates fast but whats wrong with wanting more?

 

Yeah the race lightned flywheel helps alot but, ive heard that a heavier flywheel is better for the hill ..... but it does rev faster and have better response ... Austin
