I have a brand new billet UB 950 twin crank, 2 cylinders & head.
Please make offer.
Thx
I have had some of you tell me that this is a 900 engine and a 910 engine..now I'm not a UB expert and I dont know the exact size. Tell me what to measure and I will.
Thx
Do you know what brand the crank is for? Such as Polaris etc? I am interested if the crank fits in a Polaris base and give me your phone number or call me at 518-358-3027 thanks, Delton
You need to measure a couple of things to see exactly what you have. A UB 950 has an 88mm bore and a 78mm stroke and the cranks that were built for the billet case have a 6" center on the rod journals. Stock Polaris cases have a 5.5" center on the rod journals. The easiest way to measure the stroke length is to measure from the bottom of the tranfer ports to the top of the cylinders.
Ok I took it in to the local mod shop and they said this is a 76mm stroke.
Yes sorry I have sold the heads (they did not go with the UB engine anyway)
I still have the crank & cylinders.
