I changed the top and bottom gaskets on my '07 using the Cometic setup. It was relatively easy. Before anyone asks, yes the pushrods were down and easily moving.

I cleaned up the residual left from the old gasket using carb cleaner and WD40. Both on the head and the rocker boxes. After I buttoned everything up I let it sit an hour. I started the bike for about 30 seconds and turned it off. An hour later a 1 minute heat cycle. After another hour I ran the bike and let it idle. The garage was opened and it was cold. After it warmed up it started to smoke. It's a light white smoke coming out of the top. No oil seems to be leaking. There doesn't seem to be any strong odor to it. It did it again after I started the bike this afternoon idling for about 2 minutes.

Is there a break-in that's causing this? Is the carb cleaner and WD40 burning off? Did something go catastrophically wrong?

The engine sounds fine.

Thanks

 

I'm going to guess it's simply a little residual oil burn-off...that stuff gets everywhere and can be hard to get it all cleaned off. Keep an eye on it, but you should be OK.

 

yup what he said - its all the left over crap burnin up

 

In my case, the WD40 burning caused a lot of smoke after we changed the head gasket of my front cylinder a few weeks ago. It'll just burn off and go away.

 

Go for a short ride and get it up to operating temps. If its not leaking you should burn off the residue.

 

Thanks


It's pretty much what I thought. I've changed the gaskets on my last Sporty (Hey, who doesn't have to change leaking gaskets on a Sporty?). I just wanted to be sure I didn't do something catastrophic. Once you make sure the pushrods are in the down position before removing the bottom rocker box, it's fairly straightforward and tough to do anything really drastic. I hope. lol

 

Probaby crap you sprayed on. Give it time. And double check your torque values on the rocker cover bolts.dont over do it. The threads are like butter.

 

Believe me, I learned from a previous bike that the bolts snap like twigs. I had misread a torque value and "bam". After more years of experience and patience I go in steps using the torque wrench.
