Hi, not sure if this is entirely normal for an 02 F4i with 34000km and hindle exhaust, but it is a bit annoying. I start the bike in the morning on a typical day and it revs up to about 3200rpm and stays there for the next 3-5 minutes after which it slowly dies down to normal 1200rpm idle. It spews out quite a bit of exhaust in this period which is clear when theres no humidity, but there is quite a bit and it doesn't seem normal. It doesn't really smell out of the ordinary, but it just fills up the surrounding space and can't be good for ya. After it warms up, runs like a beauty. Its always been like this so i havent really gotten anything to compare it with. Bike was tuned up, oil changed, air filter cleaned, didn't find any other issues. Sparks are still good. Any ideas? Would it be worth fixing?
