Not much news lately, the crank will be with me Monday or Tuesday after having the new conrod fitted by Eastwood racing, a new genuine Honda left hand crank bearing is being sent by Dave silvers.
In the mean time I have painted the cases and rocker cover.
The cylinder head has been cleaned and the combustion chamber has been reshaped into a cross between the original shape hemi and a pent roof combustion chamber by cutting the chamber at a flater angle to the valves then blending it in (you can just about make it out looking at the picture), a bonus is that the spark plug tip is less shrouded, this has also increased in volume from 60cc to 75cc which will give me a compression ratio of 7.5:1 with the spacer plate and the piston I have.
Already thinking about next year, I am going to put an ignitech programable ignition on the bike it has a single wire activated 2nd ignition map, so I can have a cruise map with lots of advance to support the low compression motor and a retarded map when on boost activated automaticity by a pressure switch in the intake plenum, I also want to fit new seats and 2mm oversize exhaust valves, but cant afford either of these this year

Lovely, shiny, engineered baubles in the front room at Christmas! 😋

Thanks, Its reasonably engineered but its not perfect :) I found a way to fit the XBR chain cover with the XL alternator cover, narrowed the cover by 10 mm lines up quite nicely and looks ok

Looks like it was made by Honda - you must be well chuffed!

I have started on the plumbing, and its a very tight fit, this is the reason why I had to use an XR600 R inlet rubber. I also had to trim a fin so the pipe could route correctly
