I thought this topic was a perfect place to give folks a preview of what we are going to be releasing this summer.
At this point I only have the front head complete and am working on the casting pattern for the rear. All fixturing and programming is complete for the WR combustion chambers.
As you can see the entire chamber is CNC machined into the solid casting. These still need to be polished.
Casting the bottom of the head solid allows me to put a riser directly in the middle center and this avoids the porosity common in the factory castings, and machine any combustion chamber into the head. Imagine being able to machine a chamber for a WR that uses the latest KR dome piston.
I can also make high quality racing heads for your WLDR or WL.
Castings are poured from certified 356 aluminum alloy, heat treated to a T6 condition.
Material thickness is increased over the combustion chamber only, which allows all critical dimensions to be the same as stock. Appearance is almost identical to the stock head. Will be available using 14mm ¾” reach spark plugs (18mm special order).
I will post more here when both heads are available.
I will have these at Oley on display along with my other stuff and can answer any questions.

I have been flat tracking Royal Enfield 500 (1 of them is #1 in the classic 500/750 class this year beating Gold Stars and KRs) singles for the last 12 years and have found the Albion boxes to be very robust with the exception of the possible false neutrals between gears if not shifted with authority. I think the clutches STINK! The were all slipping on me coming out of the corners.
About 6 years ago I started using Bob Newby belt drives and clutches which I love.
They use friction plates from the Jawa speedway bikes and I think springs. Absolutely NO slip or problems on the starting line.
