Ripping into it...

So when I first got the 400/4 it didn't idle, it didn't run past 3,000 RPM, and it didn't have any power when on the barely did 20mph.

The previous owner (PO) had the biking running perfectly last summer, but over the winter of 2009/2010, decided he would upgrade the exhaust and go to pod filters on the carbs. This required a new set of jets, which are hard to come by. So the PO decided to drill out the jets. When he put the carbs back together, he used Permatex sealant on the float bowls, resulting in a gumming up of the idle jets, and who knows what kind of situation with the drilled out mains.

Here you can see the float bowl seals with the Permatex sealant on them...falling apart. Also a small nick in one of the floats:


The condition of the carbs after cleaning them out the first time:

The Number 4 Carb jet holder looks a bit corroded, but I think it'll be ok:

So now I'm waiting on new jets.
