I already bought, just waiting on them to come in. A RK 520 chain and Vortex 15t front and a 54t rear sprocket. I should be doing 2nd or 3rd wheelies in a few weeks. Ill tell you all about it. is 54t able to fit on the back?

Also my left exhaust is frickt up. Can I just block the Y pipe so that just my right exhaust takes all the pressure and take off my left pipe ?

 

yep the sprocket will fit on with little fuss VTRstunter on www.ozfirestorm.com has the same from memory..
you can block off i pipe st the 'y' section but it would be down on power and probably pop back thruogh the carbs a heap much back pressure

 

just buy another factory off ebay, they go for around 50 or less.
