Hey jetlee, I understand your point about modifying before fixing, the Blast is pretty simple, and it has a carburation problem. I figured that since the cv carb on the blast is being a piece of crap I could install a carb off a sportster, jet it down, and possibly solve the problem that the bike is having as stated in my other post. What would you recommend on the running issue {read my other post}. Not looking to get people cranky, just looking for answers, have had a bunch of big bore singles {white bros, baker} and built a bunch of big twin Harleys but this one got me stumped.
