Hey guys, I'm lookin to drop some teeth on my sprockets to get more bottom end punch, without losing a lot of top end. I really have no idea where to start in regards to what tooth number to go with on both sprockets. So what are you guys running? Thanks for the help!

 

If you drop one tooth in the front is its like droping 3 1/2 in the rear....

 

yea i dropped one on my rappy 350 and it really helped trail riding and gave alot more bottom end muscle only takes about 5mph off top speed at the most

 

What all have you done to the YFZ already?
I put a DR D pipe on, took off the airbox lid, re-jetted, and it has a TON of bottom end now!
I can literally just about let it idle around.

If you still want to get more bottom end, and you have already modified the exhaust, just go with a 13 tooth front. It's cheaper than messing with the rear, and just as effective.

 

I havn't done much to it yet. I have the intake, but I don't have the cash for the pipe yet. I'm gonna get the LRD real soon, and then I'll jet and pull the air box lid. It's never enough power for me though. I always want more. I also have the extended warranty, so I can't do the cam mod or anything internal, so I'm tryin to squeeze out what I can for as little $$ as possible.
