does a coolhead for stock cylinders fit a 68mm cub cyl, with the proper domes?
how will a 68mm cub 4mil compare to my fast dune port 4mil?
I couldn't find any info on the cyl head.
china has some of the worst steel ever put out, the crap they produce is not cleaned well and has lots of crap in it. I would just keep my stock stuff.
why would you want to unload that junk on a fellow BHQer?
find some good used ones on here or ebay.
on one of our shees we had a simular issue, we found the one wire carroded were it goes in the coil. it even checked out ok for resistance , fixed it now it is fine.
the reeds could also be your issue.
there is not supossed to be but some cut a small hole in the cover so they can adjust the clutch without removing the cover. take the screws out and reseal it.
get out the cc and call a site sponsor, tell them this can't ever happen again!!!
remember the 700 rappy's are even faster, so go big.
10mil 72mm bore cub, drag ported with all the goodies. should get the job done.
