My trusty 1994 Pan European with only 30,000 miles on the clock has recently become "Smokey" when first starting up from cold! This clears once up to operating temperature but worrying for the first couple of minutes running! This isn't just condensation but smoke and first became really noticable when I had a Motad pattern exhaust system fitted some months ago! The new exhaust may be just coincidence but has anyone else experienced this? Otherwise I'm thinking "wear on the valve guides?" or "sticking piston rings?" Any views?

For the first 10 or 20 seconds there's nothing - then a lot of blue acrid smelling smoke which lasts for another ten or twenty seconds before gradualy giving way to the more familiar, white cloud of condensation. The original exhaust did have a small drain hole underneath but I can't see anything like it on the new one! The smoke is always far worse if I've started the engine and only run it for a few minutes, when moving from the back of the house to the front in the evening, ready for a quick get away for work the next morning! The next morning it really reeks!

Check the air filter and the bottom of the air box for contamination,it could be getting some oil from the crankcase?.Via the fuel pump and fuel filter you will find a diaphragm type fuel tap(automatic).The rubber diaphragm can start to leak and cause the bike to over fuel or flood when stood for a while or cut out,as it turns itself off.This is quite a common fault with older pans.These are the things to check out before delving to deep,if your bike has air suction valve,s into the exhaust ports(not sure) then this is another thing to investigate.Good Luck

TLC for my Pan
Thanks for the the advice guys! I've had such long and reliable service from this bike that it owes me nothing even if it had got a serious problem! I'll keep an eye on it for now and try to give it more care and attention than it's had lately! It could probably benefit from a full day riding to blow out the cobwebs!
