Hi All!

Seems that a local Italian dealer is developing and starting to sell, a modified version of the last type Jolly motor Exhaust.... They claim it has a total different Power band, and a 'full power' from 8500 to 13200 !

It has one Exhaust for side... and the silencers are carbon covered.....

Available for rs250 and rgv 250....!!

I will try to discover more :D

If you rev your motor over 12,000 rpm make sure you do a full balance and weld on the crank. 13,200 rpm with the right porting, jetting and carbs could be 75+ bhp.

Yes, I can Imagine that... for standard engines.. correct peak of power , should be around 11.000 to 12.000 revs...
