Hey, I my specs should be in my signature. But when I go down hill I have to keep like 8/10 of the throttle open otherwise if I open it up fully it feels like I've shot down a gear and begins to slow me down. What could be causing this? Obviously it's some sort of gearing problem, and my bike tops out at 38mph up hill and on flat and down hill
its not jetted correctly if it wont go full throttle but will go at like 8/10'ths throttle. that or its just the main jet semi blocked so needs cleaning regarding your top speed my old katana with the same engine only done 40 mph on the clock untill i put a top end that was revving up to 11,000 to get 55mph on good day
No it will go full throttle, but when I go down hills and pull full throttle it starts to slow me down, fine on flats and up hill.
