Hello

Will shortly start building a motor for my GP on 200 casings. I fancy an old school Jap piston conversion using one of the two barrels I have in my shed. Crank wise I'm keen on an Indian GP crank with a Vespa Ape rod conversion or a Yamaha rod, depending on the piston I end up using.
Pipe will be a JL3 and a 30mm PHBH carb will be on the induction side of things. I can get a bit of barrel skimming and piston chopping done at work, but tuning wise I'd like something like a stage 5 which I'd get done by a man who can.
Looking at the old MB site it looks like my options are:
Using an Ape rod with 18mm gudgeon pin diameter - Suzuki PE250 piston to give 205cc; Suzuki TS250 piston to give 225cc or a Polaris 750 piston to give 220cc.
Using a Yam rod 115 long - Kawasaki 440 jet ski piston to give 210cc.

Anyone got any experience of any of the above - either pistons and / or cranks - at all please?

Any advice, yarps, narps and gentle abuse welcome.
Any local crank building contacts and tooning contacts welcome too. I live in North Brum.

cheers

Only experience I`ve had is my old Taffy TS1 200 that used an RD400 rod with a Yamaha IT175 piston which was a good motor, but if yours is an iron barrel, piston ported, this piston and I`m sure similar pistons have windows for the reed valve, which I don`t think will suit piston ported motors.

When i read that title i thought this would be about a homosexual double act............................

harry barlow is your man (if he ever answeres his fone ) he can get all the bits you need for this type of conversion and do the crank rebuild

No, that's Long Rod and Big End.

I've ordered an Ape rod today and will look out for a Suzuki piston.
Met Harry at a Holiday in Holland rally about 10 years ago. Sound bloke, spent a fair bit of time helping me sort an ignition problem on me scoot (think he was pretty intrigued I was still running points!) after it packed up literally at the entrance to the rally. He wouldn't even let me buy him a beer.
Cheers, got a few names in the hat to do t crank and choooooon it....

I'd phone MB... He's he master.
