Rust on header and "mud" stains on muffler?

Recommended Posts

I have rust on my header I think... Its that or just dirt that I cant get off and the same for my muffler except on the header it looks more like rust and on the muffler it looks more like dirt mud stains.

Question is, how did this happen and how can I get rid of it.

When the pipe gets hot the dirt burns onto it try taking a wire brush to it not to hard because you don’t want to scratch it.

Its dirt, not rust (my TTR looks the same way) You just have to take a wire brush to it untill you knock all of the dirt off. It will take awhile

It's like that on my husband's WR. But nobody else bike has that problem. I've tried everything to clean it but it doesn't come off.

Ditto on the Scotch Brite pad and WD-40. Takes a little time, but it will be looking good after a bit of work.

For anyone out there with a ceramic coated or chrome exhaust that's reading this, the Scotch Brite pad is a no-no, just WD-40, a rag, and a lot of elbow grease.

I do it the easy way, glass bead it then re paint it. It'll look even better that just taking a wire brush to it.

Just finished the same job on my WR450. Took 100 grit to it and a wire brush on the end of my cordless drill to get the tight spots. Came out looking like a champ, no prob.

Wire wheel on the bench grinder ought to make short work of it also. Should have thought of that before I hand did mine.

Also spent less than $5 replacing the stainless and other fasteners which definitely also freshened it up.

Takes a bit of time, but put some tunes on and no worries.

Cheers-

Neil.

wash the bike better after riding and spray the exhaust down with wd-40. It will keep the exhaust looking new-the wd-40 should be handy after washing the bike anyway because you are supposed to spray the chain and pivots to keep them from rusting
