Straight dope on the 372xp BB kits

[openloop]

I hear conflicting reports of the Baileys BB kits for the 372xp's. Are the issues that people have with them due to plating, stock porting, port timing, or casting imperfections? Do they make power comparable to the factory XPW P/C's? Or are they really only good for a person planning on porting them?

I had one a few years ago and power was close to an xpw but I would say no better. It is cheaper and will make a good runner with a little work.

Some of these guys are the ones to ask....

I have a 75cc XPW top-end on my 365. :msp_biggrin:

I like the OEM stuff.

I have run them both in stock form and didn't notice a difference. Longevity wise both cylinders are running with out problems (3 years of firewood cutting). The big bore is now ported and the oem 75cc is stock. The ported bb kicks the snot out of the stock oem.

I don't see a problem with them.
