They're for a mate.
Anyone got any suggestions for a source?
Cheers,

Hi Tom
There have been several sets on fleabay recently
You need to know the conrod and flywheels part numbers to be sure they are M21 though
Also try Owens motorcycles www.owensmotorcycles.co.uk/bikes.html‎

Building a special? Otherwise you'll only gain a little more torque and about one horsepower! If you just want more power just weld up the head to increase compression for a gain of about 10 mph!
