Kinda worried....

My 95' CBR600 F3 smokes on startup up. After about 5 mins the smoke stops. It only does this on a cold start and never warm. As you can see it takes 1-2 mins for the smoke to start. Im hoping its only the valve stem oil seals but any input would be appreciated. (Im aware of the cct rattle)

give us a little more info on your problem

cold where you live?
rain any latley?

feel/smell the smoke.
smell like oil/gas?
feel moist?


sorry those are childish questions but I believe they can help us diagnose the problem a little better.

when i put oil into the sparkplug holes (to improve the compression after i flooded the bike) my bike burned worse than that for about 5minutes.

 

ok...

Not being mechanically minded at all.... I would say its probably not condensation...(as it will do this anytime of the day) Its not the weather... (it will do the same after 5 days of full sunshine) I've kept a check on the coolant level and its not moved a drop. However he oil has gone down a little. It will only smoke like this after sitting for 4 or more hours, never smokes when warm. And as for the smell... I've never smelt oil burning. But it doesn't smell like fuel.

Im puzzled...

 

Nice f3 like that mircon exhaust sounds nice.

Maybe you have an oil leak?

 

How many clicks on you're bike? You may be right about the valve stems, but it could also be rings, when you 1st start up, engine is cold (smoke) but as the bike warms up you get expansion which seals it again.
Regardless, you're looking for smoke when the bike is under load, taking off from the lights, accelerating up a hill, that sort of thing, & unless you had someone behind you at the time, you would never have noticed it.
Few bikes I've owned have done the same thing & especially after a night parked on the side stand & never had any further problems. You can also get smoke if you're inadvertently over filling you're oil. There is a minimum & maximum amount amount to put in & it does not have to be at the max level & a little less may stop the problem
Keep an eye on you're oil & monitor how much it goes down by for say a week.Then if it drops you know you have a problem.

 

Bike has done 27k miles... As for checking the oil what would you recommend... Some people ive spoken with say check it warm... others say check it cold.

has not been much help with this issue either...

 

Going to get somone to follow me on a ride.. (when its dry its like a monsoon in the U.K atm) hopefully I can tell then if it smokes under load. But anymore insights in the mean time would be much appreciated

 

compression test?

 

Got a compression testing kit on the way from ebay... What is the correct psi for each cylinder. Or will that be in my workshop manual...?

Edit: Ignore that. I think I've got it... it should be 170 psi .. ish... Right?

 

During the winter, I get white puffy exhaust and it goes away one the bike is warmed up. Another tool that helps with determining if rings or valves, a leak down test.
