Hi mate

Give Harry Barlow a ring at Pro porting regarding the cylinder if you can get through to him mind!

The best of luck.

The MHR 57 on your 60 crank will go like a heavily fettled old 210, straight out the box. Just bolt it on and set it up. I fitted this set up on my 221 after the old 210 wore out, a few months ago and now it rides like a motorbike. Goes over 8000rpm on a 35 tooth 4th. No gear gaps, pulls like a train.

I'm using the mhr 60mm cylinder single piston modified, v force reeds, ported barrel base matched to the ported pinasco Reed cases, one off pipe, higher gearing with bgm forth (it use to rev out in forth with the old gear kit)
Pulls like a fella in a brothel... want more power... Harry's ultra busy..
