Doesn't sound like it, As I explained in the follow up post. I had never heard of Ultima, when I saw the advert I presumed it was a direct fit, as say the S&S motor. Seems like I sold you all a bum steer, unintentionally. So apologies all round.

Anyway, I am at 42kmiles, just about to fit the fourth set of lifters. First set replaced as a precaution at about 15k. Second set replaced at about 30k because they failed and took out the cam and pump. so now replacing as a precaution at the 42k mark. Had a rebore around 20+k because it was drinking oil, now it's just started to sip oil again. This time it will get a glaze bust and rings. If I didn't like it so much I'd get rid, plus the missus wouldn't ride on anything else and I ain't buying another and I know who the boss is.
