Thank you for your reply. I missed that in my first reading.

Is it safe to assume that the 2.0 Air Correction Jet is utilized?

Mike, Thank you for sharing this. Upon pondering over your tasty words, a thought came to mind in reference to the pin location in the piston. Would it be possible to move the pin further away (down) from the oil wiper ring and make up the difference by shimming up the cylinder base...

My deal is to make um fast but you definitely need to stop um also!

Pamcopete, Thank you for the info.

How do you think this will relate to ReycleBill"s Project Ideas? BTW...Thank you for your bulletin post, I have saved it for future reference. Regards, Dave

This post is direct to PamcoPete: I have a 1969 XS1 that I built in 1970 as a flattrack racer with a Trackmaster frame, Branch Flowametrics head, Tom Sifton Cam and the crank wheels have been balanced and the taper on the crank has been re-machined for to fit a crank fired magneto (Yamaha...

I do not think shaving the pistons is the way to go. The reason I am saying this is even though you may be reducing the compression statically, you ultimately will be increasing it again artificially with the supercharger. In addition to the possible detonation caused by the increased...

Hello All, My project is refurbishing my flattracker that I built and ran back in the 70's. Back in the day I had machined the crank to accept the the magneto (points) from a DT2MX (Ignition only, no lighting). I am desiring to upgrade with 277 re-phase and Pamcopete ignition. Here lies...

Your calculations would be correct in a linear measurement but you need to be doing area here. (Area = pi × r2 ). So in conclusion you would have a 106.066 mm Bore with a 74 mm Stroke With all this being said, I truly believe the best avenue to pursue would be the re-phase 277 because it will...

Thank you (XSLeo and GreasyC) for your input. There should be plenty of life left in the 256 crank and rods. Just for your info the engine had 300 miles on it when I started in 1970. Since then it was ridden (as a 650) on the track for no more than an additional 500 miles. I got to thinking...

Hello All, If you replaced the stock 256 rod/pistons with 447 rods/pistons on the 256 crank, would that be a workable arrangement? The reason I would desire to go this way is that I have a 1969 XS1 that I built in 1970 as a flattrack racer with a Trackmaster frame, Branch Flowametrics head...
