Smoke on startup.

#1 PostAuthor: shep65 » Mon Oct 06, 2014 2:49 pm

Z1b that's been standing for a few years, recently got it back on the road but on start up 1&2 smoke real bad.

I'm pretty sure it's oil rather than fuel and it clears within about half a mile and stays clear until next ride.

I was thinking valve stem seals as I guess if worn bores/stuck rings it would do it all the time.

Any advice greatly appreciated.

Apart from the oil loss factor will leaving it do any damage?

Much of a job to do?

it wont damage the motor as long as you keep your eye on the oil level. its not a big job but you will need a valve spring compressor

I'd say valve stem oil seals too.

The only problem I'd say is (depending on the exhaust) blueing of headers on 1 and 2.

Standards, I'll keep an eye on them.

I may look into it over winter as the rest is pretty tidy so would like to get it as good as possible.

Thanks again.

Double skinned headers will be OK.
