Re: Snapped stainless sterling
Yes mate got home fine (but wet). Bad news is the sterling down pipe was for a vespa but i do have a lammy U-bend but it's 48mm, probably too big but you're welcome to it if it's any good to you.

Re: reed valve
You would need to mark the position through the inlet port with the piston fitted to the rod. The idea is to achieve 360 degree of inlet opening. Cutting 3 mm off the inlet side of the piston skirt will help too. But your best bet woul be to read up on the theory first ;) Thanks coaster, thats the ...

Re: reed valve
With the greatest respect Gee, if you don't understand how it works, why do you think that fitting a reed valve is good idea? What problem do you have that you hope the reed valve will rectify? most of the good kits are reed valved, i know that if you stop the fuel spitting out there will be more f...

reed valve
If i fit a reed valve to my 185 kit, how ( or rather where ) do i put the ports in the piston. What size should they be?
My guess is that they line up with the inlet port, but i dont fully understand how this works tbh.
Any advice gratefully recieved. :wtf:

Re: Did I F' up my engine rebuild?
Is the spring and retainer on your front sprocket seated correctly, there's not a lot of clearance from the chain case to the bolt, it could be fouling there.
