Just fitted my new full system and it says on the fitting guide, note* exhaust may smoke a little the first time due to burning oil off the new pipes. A little? I thought my bike was on fire or some wire were touching the exhaust and melting! Anyway I kept my eye on it and ran the bike up to temperature and the smoke from the headers cleared and stopped coming out of the can as well. All good I think, so I turned the bike off and now there is smoke coming out the can with the engine off? It took a good 10-15 mins to stop coming out. Is this normal as well? I've never fitted a new system before
all normal dude. anti corrosion coating burning off which is put on at manufacture so that in storage it will not corode due to moist or damp conditions. much the same as brake discs and clutch pressure plates for cars
As Racman says perfectly normal, just manufacturers coatings. Sometimes the coating is quite acrid until totally burnt off.
