A forum for owners of Yamaha TTR250 trail and enduro bikes!

the chromed mirror arms on my 2011 model were going rusty due to chrome pitting caused by being struck by all manner of abrasive matter thrown up by motorway traffic. I had considered purchasing mirrors that had stainless steel arms. [ are they available ] but a thought struck me that heatshrink tubing would be the answer. it comes in a range of colours and the 16mm size will with a bit of pulling and pushing slide right up the arm. then you just have to heat and shrink it being careful not to damage the mirror head. to treat the corrosion I got a tall glass bottle that was wide enough in the neck to accommodate both mirror arms and filled it with rust convertor [ phosphoric acid ]. leave long enough to dissolve the corrosion, rinse with hot soapy water and either paint the arms with anti corrosive paint or use some sort of product like fish oil or tectyl to prevent the rust from reactivating under the heatshrink. you do not want any moisture getting trapped under the tubing either so make sure you properly seal the ends.
