Yamaha Using a 525 chain on a Raptor 660?

Recommended Posts

Hey fellow brappers,

I have to change the chain and sprockets on my ol ladys 05 raptor and right now its the stock set up with a 92 link 520 chain, 13t front and 40t rear...so anyway i have a brand new 525 chain in the garage not being used and since i have to buy new sprockets anyway i was wondering if anyone has ever done this? i know it is a heavyer chain and i would have to order the wider 525 sprockets (if they exist) but do you think i would lose that much power by using a heavyer chain? thanks in advance - looking forward to your comments!

 

..... also i need to repack the fmf powercore 4 and replace the nose cone and screen Spark arrestor and possiabley put a queit insert in, does anyone know where would be a good place to find these things?
