I keep reading about the lack of a bushing in the case...makes me wonder if the .65 I got is really a bargain?
I bought what was advertised as a new, still in the plastic bag .45 for $32.95 (+ 6.95 shipping ) but when it arrived, discovered that it's a .65
That didn't bother me, because I just wanted to get a Sportster to add to my K&B collection...(it's the only one I have )

I'm thinking it must be a 'tweener because it has the later (modified ) head with shallower fins, but the early bushing-less case?

If I run it on a low nitro fuel with plenty of Castor, it should be o.k. though....(right?)

Jeff...sorry...don't wanna hijack your thread or nuthin'...just figured I'd ask while we were on the subject of Sportsters.
