cylinder barrel or oil pump? - 2 plug fouls today!

[fishtail]

yeah the heads already off tho... was waiting for advice before going further..

appreciate the desciption of the air filter.. I think it was too "wet" before ( about 3 months ago ) now its a bit damp/tacky... havent had issues with fouling til now...... altho I'd say it has been running rich..

I think since I can see the piston I'm gonna take the barrel off at least first - will miniumum clean up valve as suggested by Nj.

will take barrel to a guy I know.. see how long for rebore / new piston to show up.. if not a big wait I will do it now.,,

some one local said my carb might need a clean? ( only cleaned it 2 weeks ago I think - 3 tops when I swopped the carb manifold over,,, )

that some one local watched the youtube and said that the crankcase compression sounded good...

actually there's a ride out on sunday....... looking dubious now...
