In the process of building my 421 cub and am needing some helpful info.
Exactly what thickness cylinder base gasket is required on the 421 cubs? And where can I purchase them?
Will be running a coolhead with 17 cc domes....and I am located at pretty much sea level.Good idea or no? Have read conflicting reports and some suggest 20-22cc domes at sea level.
Carbs are 38mm PWK's....unsure what size jetting to use...
Pipes are RDZ oof's
The bike will be a asphalt drag bike now and then,primarily a show bike....but HAS to go !! lol
Are my sights set tooo high in hoping for 100 hp?
I have lots more questions and hope to get to know some of you over the next bit as I finish the build
Thanks
