Anyone have any good (useable) used / new Sportster CP rods in 8.5” for the 86-99 3/5 pc bolt together flywheels with a 1.250 crank pin?

If yes, are they .791/.792 or .927 piston pin

Picture for attention
Thanks

These M8’s are making some big power on pump gas.

I can’t thank all the dealers & customers that trust our cylinder head packages.

When you have to make the race you think outside the box.

A friend got a set of heads with the pushrod holes not machined for his stroke / case combination. We opened the inner ID hole up to .750” thinking we might gain what we needed but no go during mock up.

Instead of welding them up and starting over, will open the holes up .125” and move up to a larger o-ring size.

I machined these adapters that press in the upper tube today to gain the clearance we need. Will shorten the clips at assembly time to adjust the new needed length for proper tension.

Custom valves I’ve been waiting weeks for and here’s what was received.

Nothing I can’t fix with some machine time in the lathe but more time eaten up that isn’t billable.

Not worth sending back and waiting more weeks- frustrating

Racer community is a cool group.

A racer is waiting on new wheels and would have missed the first race of the season… another racer allowed me to pull the crank of his cases (due to his race season starting later) allowing us the chance to pull this off.

For the racer in need I am thanking the racer that gave it up today. 🤙🏻🤙🏻🤙🏻
