Am going to do a compression test but have put the new plugs in and fired her up and everything seems sweet the odd thing is if the rings were shot I would expect the bike to smoke and there is no blue smoke whatsoever!

I'll let you know how she gets on!!

Should add I'm guesssing this is ring or stem seal related but am hoping someone is going to give me another cheaper reason!!

Have just taken the plugs out of my owo1 to change them (Nippon Denso X27ESR-U) and am a little worried that the threaded part of the plug and collar below is soaking wet with oil :? on all plugs! Excuse my mechanical ignorance but this cannot be good having oil in the cylinder can it? Can anyone he...
