Hard drive / WPS selling 124 / 128 cylinder and piston setups.
« on: February 09, 2018, 06:16:20 AM »
Was notified yesterday by our hard drive rep that they are now selling 4.250 M8 cylinder sets.  Retail is just under $500 and they are also selling the Wiseco pistons for the 4.375" stroke.  I guess the 4.5 stroke setups will have to use another piston mfr.

Bolt on? No case mods?

Interesting info, Thanks. Looks like they would be a source for the steering dampers people are always looking for.
Just saying,

Unfortunately it does indeed need a case bore to work.

My hard drive rep let me know that v-twins literature must be wrong because everything that they have says that is a cylinder does not require boring of the cases.

Is the cylinder stud pattern for the M8 the same as a twin cam?

Maybe I'm reading it wrong, looks like they're a Japanese MFR, and supply to V-Twin, Tucker Rocky, etc.

Looks like 124" barrels ($460.00) and Wisco coated 11:1 pistons ($410.00) sold separately. Rings and gaskets extra?
