markparrish Posted June 25, 2019 Report Share Posted June 25, 2019 Just thought I'd share my photo of the day! I've been reading up on methods to clean out my pipe of my Rev3 (I noticed a bit of smoking recently, particularly when riding between sections on a big loop, when the engine was running hot and for a few minutes). I am not losing any gearbox oil and have recently changed mains/seals, so suspected it was the exhaust. I guessed it was a build up of unburnt oil and crap and on examination I think it was the cause (I ride it a bit gently and probably never give it a good enough blast). There was also a fair amount of carbon too. I decided to try the burning method; I started things off with a small blow-lamp and also aimed the hot air gun down the pipe. It soon got glowing inside and then the oil ignited. Once it was going I left the hot air gun running. It took a few minutes before the flames went out. After allowing it to cool I tapped out some ash and the insides looked pretty clean. The aluminium mid section wasn't harmed in any way, but I did dull the chrome and introduce some nice blues/golds to the header pipe!, which is now carbon free. I cleaned and repacked the silencer in the usual way (no burning!). I have yet to ride it properly but it seems to run cleanly, pulling well from idle, and sounds a bit less noisy. I'll report back after the weekend. Cheers. 1 Quote Link to comment Share on other sites More sharing options...
arthritic Posted June 25, 2019 Report Share Posted June 25, 2019 Next time try a trickle of water from a hosepipe on the outside to control the heat so its just burning, you can clear the insides without it affecting the outside. Do it once a year and its a simple task that's worth the effort. 3 Quote Link to comment Share on other sites More sharing options...
