roddy 845 Posted March 4, 2016 Share Posted March 4, 2016 Could anyone shed any light on keeping the downpipes and exhaust clean and bringing them back to their near original condition. Mine are looking a bit sorry for themselves and not sure if to use a scourer or not? Link to post
bazza 3,629 Posted March 4, 2016 Share Posted March 4, 2016 i agree its a tricky one.is the "hole" in the plastic sump plate there to let heat out of the exhaust port area -or let cooling air -and water -in? Whatever it makes that area grotty maybe Tex has a tech answer for us? Link to post
Guest GBH Posted March 4, 2016 Share Posted March 4, 2016 Best stuff I have found for cleaning the down pipes is Wonder Wheels. Brush it on and rub until it takes all the muck off. Once you have them clean an occasional use will keep them shining. A word of caution I would not use this stuff on wheels it will take the lacquer off but on stainless steel is fine and use protective gloves since the stuff starts to burn skin. Link to post
embee 7,288 Posted March 4, 2016 Share Posted March 4, 2016 Solvol Autosol is perfect. Bear in mind that the pipe will discolour to a brown colour, that's just the way it works, but you can delay it and remove most salt based staining. 2 Link to post
jef 9 Posted March 4, 2016 Share Posted March 4, 2016 In the interests of "style" it seems to me that the front mudguards on bikes are too short, and all the road cak is sprayed onto the engine and the down pipes. Does a 'Fenda Extenda' help ? Link to post

Tex 36,817 Posted March 4, 2016 Share Posted March 4, 2016 Yeah, nothing too technical required. Solvol Autosol, some fine wire wool (if heavy deposits need tackling) and lots of elbow grease. 2 Link to post

michael 324 Posted March 5, 2016 Share Posted March 5, 2016 +1 on Autosol. Not a particularly rewarding way to spend a few hours in the garage…well perhaps-but only until it rains and gets grungy again. I have a 4" extension on the fender and it keeps some of the crud off the header pipe. Link to post

bikerbampi 542 Posted May 3, 2016 Share Posted May 3, 2016 The front part of the exhaust nearest the engine contains the catalytic converter and gets extremely hot to do it's stuff so will always discolour no matter what you do to it. Personally I think it is not worth the bother trying to keep it gleaming. If it is too unsightly, I would try to cover it up with something like a fine mesh to still allow the cooling effect for the cat. Link to post
sandalfarm 2,766 Posted May 3, 2016 Share Posted May 3, 2016 Wrap it with that tape stuff that Harley rat bikes have on their down pipes, I found that the down pipe was pitted with debris thrown up from the road despite having a fenda extenda Link to post
