Anyone notice these wear issues?

Taking my suspension apart yesterday for service on my TE 250. I noticed that the chain is rubbing the inside of the frame just before and above the countershaft sprocket. Anyone notice the same? Are there any aftermarket guards to mount that address this issue? My chain is adjusted properly ( minimal slack with swingarm compressed parallel to ground).
Also noticed that the shock mud flap is wearing 2 grooves in the swingarm where it rubs. Is there a better one out there?

Don't know why chain rubbing but on the mud flap situation. Use a razor knife and get rid of the two ridges that are wearing the grooves. Acerbis makes a generic one with the ribs towards the wheel.

They have rubbed the frame since 08. Turn your master link around so the clip is on the inside. It wont cure the problem completely, but it will help.

I noticed a rub spot on the frame of my new '09 TE310 at about 500 miles on the odo. It sounds like your rub spot is in the same place mine is. My solution: narrower chain. Recently I purchased a couple of DID 520VT Narrow T-Ring chains ($90). The stock Husky chain measures 20.4mm across the staked pins, and the DID VT measures 18.5mm across the staked pins, about 2mm narrower.

I'll update my TE310 web page when I'm finished: TE310 Modifications

I was thinking about making some type of wear guard. Maybe a piece of PVDF pipe wrapped around the frame tube might do the trick. I'll post an update when I come up with something.
Darty,Thanks for the Acerbis tip.

They've rubbed before 08. My 06 rubbed as does my 08. The frame material is pretty darn thick right there, doubt it will ever effect the structure significantly. On my 06 I tried making nylon rub blocks to no avail, the chain would rub them away or tear them off.

I stopped worrying about it.

I don't know, I never noticed it on my old RMX's. Maybe I wasn't looking. Didn't notice it until I took the shock out for service. I'm going to see if I can't figure out some solution.
