Did that kit come from a different manufacturer or is it one of the older kits that baileys uses I wonder?
What's the squish?
From Brad's photos of the OEM 660 P&C (thanks Brad )
That dark ring at the top of the bore is suspicious.
If the saw has been run, the dark ring may merely be carbon, which is normal on a jug that has been used.
You shouldn't see a dark ring on an unused jug, though. If you do, chances are it is missing plating and/or it was gouged by the boring bar that cuts the squish band.
We're not sure. It has many of the signatures of the previous generation Baileys kit, except the combustion chamber is cleaner. The last gen from Baileys has raised the floor of the exhaust port to fix the free-porting issue, greatly improved the combustion chamber, and I believe reduced the size of the combustion chamber. I have a prototype of the last gen, and it screams. It's the first ported 066 I've done that made me go wow.
Right.It only has a couple minutes on it, not enough to even get it hot.
ive installed the other 066bb kit that matt had on my old magnum. i did nothing other than a new set of rings, bolt it on and start cutting. very impressed with it but its the first bb kit ive used. have put 6 tanks of juice through it so far and its as strong as. will get some compression readings after work and post em here for everyone to see.
Right.
So I'm very suspicious that the dark ring is a bad spot. Prolly fine with the stock piston, but a pop-up piston in that jug may be out of the question.
I'd love to do a pop-up for him but can not lower the jug anymore. Plus with the squish already set at .018, you won't get much from a pop-up.
Did you check skirt to case clearance? This one only touched slightly, but could be heard and felt rocking the flywheel back and forth. I clearanced the case, and cleared it up.
Have you checked compression?
Thanks for the info, Grande Dog. I didn't think your supplier would be selling "your" kits behind your back.If these kits are coming from China, they are not from the same manufacturer as ours.
At the moment NWP top ends seem to be better quality than either recent OEM or these Chinese knock-offs.
The Baileys kits are made in Taiwan, not China.Nothing can be guaranteed in China
