Ok a new guy question, how hard is it to change the front sprocket?
I have a 520 kit I want to install, the back is not a problem and yes I do have a chain tool.
thanks

 

Not hard at all.
Just unbolt the cover, take off the nut holding the sprocket tight (this nut may be very tight if you have never messed with it). Slide the sprocket off and slide the new one on and bolt everything back up.

 

Thanks, my project for this weekend

 

To just install the front sprocket?
It will only take you about 15-30 minutes as long as you keep all of your bolts organized, which by the way, pretty much all the bolts on the sprocket cover are different lengths, so label them so you are not lost latter on when you can't remember what went where.

 

Thanks for the tip, I am installing the 520 kit 15/43

Threading the chain around is the hardest part.

 

Make sure you don't have the cover off for too long. The slave cylinder will work its way out and will draw air into the clutch master cylinder. This is a major pain in the *** to resolve. Also, use the rear brake to hold the output shaft steady as you loosen the countersprocket bolt.
