CRF450R Chain/sprocket setups?

[GlennRMK]

Curious if anyone has found a chain/sprocket setup that works well?

I'm running an 09 CRF450R with a 16 TS Kit.

Running 13/17 now and it rubs the track. 3 rides and its starting to tear the lugs on the track.

14/17 seems way tight on the TS frame. Not much clearance. 13/17 has left a couple light marks on the frame already

Anyone try anything different and get it to work? 12/16 or 14/18, 13/18, 15/18, 15/16 or 12/18?

I was thinking 15/18 might work with a longer chain? Then gear the chaincase 16/18 maybe?

Or try to notch the lugs some more?

I was wondering the same thing I have a 2010 crf250 the chain rubs the track maybe about a 1/4 inch into the lug have not ridden it yet though 13/17
should I grind out the lugs ? 2016 ts st

I put a 14 tooth countershaft sprocket on.

Surprisingly it didn't rub the frame

I have to run the Chain fairly tight to get the clearance on the frame but it seems to work.

Honestly I can't tell much difference in the gearing

I probably needed to ride it a few days with the 13 tooth to get the Chain to stretch though
