Issue: Clanking noise from bike while the rear suspension compresses while riding. Sounds like rocks hitting the plastic skid plate. It may sound like the the front brake hose is hitting the headlight.
Correction: Install a saw tooth chain roller from a 2007 Kawasaki 450F, in place of the GasGas upper roller.
The chain roller is listed under the "Frame & Footrest" then "Frame Fittings "
Kawasaki Part # 92122-0016
The chain roller does not come with bearings. I bought a generic chain roller and used the bearings from it. Little cheaper.
You will need to use the OEM GasGas chain roller bolt and spacer. The GasGas spacer will need to shortened 13mm on the longer side that mates with the bearing.
The mod is a 100% fix for the chain clanking noise. The noise travels through the bike frame and is hard to pinpoint.
The saw tooth design absorbs the shock from the chain, eliminating any noise concerns.
I had 30 miles on this roller when I took the pic. Seems to hold up well.
