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
Fancy Rod and Jap Piston
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.
Keep on keepin on

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