Im selling my 11 and im having trouble finding info on bolt on parts crossover. Ive read somewere that the p3 pipe guard might swap over. Im also curious about my rear shock spring ( id say it wont swap), tm chain guide and slider, ltr counter shaft chain guard, and the bulletproof rad guards( ive read that the 12/13 rads are wider). I think that is it. Ill drop the price if i can get a few things recycled over and not have to rebuy them. I need the bike fairly set uo and ready in the next few weeks. Thank you guys for you time!
