Came across some pics of
another Bonneville that has some nasty looking buildup after only 15,000 km. He was tearing the engine down to install a Wiseco kit.
In another thread, I'd posted about
this Bonneville who had to tear down after losing compression on one cyclinder.
This carbon buildup worries me. Any idea what's causing it, and can the problem be prevented? Is it from the crankcase breather depositing oil in the airbox, which then gets into the intakes? Could it be from crappy gas?
Hey Pat, you still running that aftermarket crankcase breather? I'd be interested in seeing similar pics as above when you do the teardown for the bigbore install.
