Valve adjustment on my SV was three evenings FYI. And I only have two cylinders! I even have gear driven cams so I don't have to muck with a cam chain. Then throttle body sync, oil change, etc etc. Keep in mind that when you tear it down you will need to find a place that has shims ON HAND so you don't have to wait for them to be ordered. Call around ahead of time to find someone that has some.

So...........

The R/R is good. Which means my electrical is in good shape.

The white smoke is unburnt fuel being forced through the system into the exhaust. So here's the lowdown on what's going on.....

My float pin is not set at the right level. It's not seating correctly into the carb and that's letting an overflow of fuel into the carbs, which isn't being used up. The unused fuel is pooling in the combustion chamber on top of the piston's causing my engine to vapor lock. When the bike is finally able to turn over and fire it forces all the unused fuel into the exhaust which is what's causing the puff of smoke when I start it.

This has been most interesting reading, just a small suggestion, might want to pull the plugs and do a compression test. Why you ask, your description of the unused fuel is not "vapor lock." Vapor lock occurs with the fuel becomes a vapor caused by excessive heat; Therefore the engine will not run. If you are dumping raw unburnt fuel into the combustion chamber and cranking it over, you might have experienced "hydro lock." This phenomenon can cause a rod to bend as the piston reaches TDC. May not be the sound you were describing earlier, but I would certainly want to check it out. Also I would be worried if my engine was more than 5-7psi difference in the cylinders. Lastly some of the unused fuel may have leaked down past the rings and could have contaminated your oil. PS not being mean or a know it all, just trying to help...AJ

I would think if there was that much fuel getting into the combustion chambers, then some would have gotten into the oil. The oil didn't smell like fuel last night.

Hush you with your sensible thinking. 2dizzy can research the shit out of things.

So after reading all the possible problems........ and what it would take to fix them....... I have decided to follow the wise, and senior advice of my forum members and.......... NOT do this shit myself......this time. I'm gonna break down and pay someone to do it, so that I can make sure it gets done the right way the first time. I'll just have to pull it apart and learn about the carbs/valves etc over the winter when I'm not going to be riding. Thanks for all the input. Even though I'm not doing the job myself, I actually have learned alot from everyone's responses, which is kinda the point of being on here. Thanks again Jeff and Daniel for your help the other night. And thanks to David for coming out to my moms house and saving the bike after the battery died..AGAIN.

Good choice. It's hard to do a trackday if your valves are beating themselves to death
