hey, so you like my graphics huh, i picked them up off ebay about three months ago and i paid $80 shipped with the seat cover and decals, i took me awhile to find the ones i wanted, it was between those and the duncan racing ones but this had more appeal than the other ones!

Thanks Wreckless

If you don't want to tear it back down, and want to run a 440 bore, I highly suggest the PC4000 cylinder from Duncan Racing.......It is billet aluminum, and is made the take the stresses of the 440 with a better stud system that is not attached to a cast cylinder. Check them out.[img]i/expressions/face-icon-small-cool.gif[/img]

Default 05 400ex oil moisture on head

I just bought this 3 days ago and owner had told me it needs choked and about 10 min to warm up. So first time out I forgot to take choke off and it started losing power after a little bit so I stopped and that's when I seen oil on the head so I limped it home and now I'm not sure what my next step is... change oil and filter and watch it?? Or take it in... I mean did my timing get messed up thru this
