New Project A2 Frame & X7 wheels & 40cc Polini

Worked on the engine today. Fitted the Real Polini Bell housing and Polini clutch. The hole where the housing fits into the case is 2mm or .080" to small, and the real housing lip is 2mm to wide. So, I tapered the hole and tapered the lip. I left enough of the old diameter in the case and the housing so I can run the stock China bell and clutches also.
Need a bracket to mount the water pump off the bell housing. E-mail Tsun, they have a bracket for a pump, it's for a Banshee Housing, but think I can mod it to fit the polini housing. I got the stuff from Capt. Highsider, looks like he use a stock gear and put the pully there and turn the pinion back on.
I also looked a Mid-South, for polini shoes, they have $200 to $300 racing clutch assemblies, to rich for my blood. The have replacement Kevlar arms for $50 a set but there for the two shoe clutches. Tsun has a Polini 2 shoe clutch for $40, think it's a China Rep, but I asked.
Anyone have a good 2 shoe plate for a real Polini that I can put Kevlar shoes on??
Tomorrow pulling up the cylinder and cutting the base gasket out, push it back down, see where the piston is to the top of the head, or Squish as we call it. Have an upper Polini gasket set here with 4 thicknesses of base gaskets, looks like .003" .004" .008" and .012". It's the thinest gold one I will be looking at first , probably won't need to go gasketless or use Yamabond w/ the thin ones. My Blata Rep eng has water going thru the cases and up the cylinder which means it easy to get a water leak at the base.

The 4 photo showing the ground out ports was taken ruff, so you could see it better, had to clean it up after. The third is it in my 6" Wilton vise, I ground the first edges with a 4 1/2" angle grinder, I was sweating bullets, going don't miss,lol.
I took the head off and the cyld up with the piston still in 2 days ago, was going scrape the .025" paper gasket and a bunch of silicon and try to Yamabond it back if I had enough clearance. When I looked at how bad the cases match the cylinder ports, I tore it apart. That's how we got to this point. My parts are being held up in Florida, cause of the Storm coming thru. I am waiting for my gas tank relieved for Fatty exhaust and 8mm, T8F-05T 6 tooth pinion for a Cag, going to try to put it on the Polini bell so I can run 8mm Chain to the X7 rear wheel. If not have the 60 tooth #25 rear gear but will have to open up the center and drill 3 new holes to fit the rim.
Getting ready to cut the rectangle tubing to extend the rear arms. I found that the big X7 alum w/bolt chain adjusters slide right inside the 3/4" X 1 1/2" steel tubing, so I plan to slot the rear tubes with closed ends and slide them in and run the axle through. Then the engine mounts on the frame will be next.
Yes, it will be higher and longer around 50" or so.

Well, were both in California, The closes track to me would be Stockton/Sacramento and that track farther south in the northern central valley. Not happening this year though. Heard from Yong yet, or Cam2 about the Gold crank??
I tried to ruin my red oil color for the 125cc ATV, it was solid so I drilled three set of 11 holes between the ribs in the center part. Got to close to the passege ways in a couple of places and filled them with JB Weld, hope they don't leak,lol. My blue one from the same people came w/ slots in the middle.
My parts did not make it here cause FedEx don't deliver on Saturday, so the USPS won't get it till Tues. morning, cause of Labor Day. Need the parts, so It's Party Time,lol.
Why are water cooled faster, more and bigger ports and higher compression I believe and there is less drag with only one ring.
