When I pulled the carbs off to give them a cleaning (which didn't need to be done), looked down the as saw so much carbon build up on the valves. I know this isn't good and need to be clean, how do I go about doing so.

I can only see the intake valve and if those are dirty so is the exhaust, I read a post about Seafoam, which I use in my cars. But, with so much on them, will Seafoam work?

 

Will that build up make a bike not start up or run?

 

i would spray them with carb cleaner. saturate those valves with the stuff. let it soak a bit. then you can burn it off. i would change the oil just in case ANY seeped by your piston rings.

 

No, for the answer of bike not starting., try messing with the idle **** on the side of the bike by the fuel ****.

I can get the intake valve but not the exhaust valves. Seem like I be investing in Seafoam.

 

Pull your headers and you'll get the exhaust valves.

 

Well, that will be my weekend chore. Plus, I need to pull the carbs again, when I re-installed everything I notice I didn't put one of the carbtube clamps on.
