Re: sip stud.nuts coming undone

I went round and did the same to th...

Re: exotic cylinder conversion mystery ?

No, not the gas-gas, the guy who run the dyno had a modern street bike/racer under a cover. I think it was an Aprillia based bike but the engine had a Rotax 250 top-end grafted on it. The owner said he had 45hp out of it. Eden will fill in the gaps. The gas-gas in the Lammy frame is/was a trials eng...

Re: exotic cylinder conversion mystery ?

Eden, the lad who did the dyno had a modern race bike with a Rotax 250 cylinder on a (I think) Aprillia engine, did he say he got 45hp out of his. think it was an ex cart top-end (watercooled). I had a look at it but didn't ask him.

Re: BGM silent blocks too big?

Re: rd400 rod with suzuki ts 250 piston

Bringing this conversion back up to date, I have a complete kit which I'm about to build to a casing. Crank = 58/110 (Ape rod) with 18mm eye, TS250 70mm piston and barrel bored to225. The piston came with a 16mm pin to fit a standard rod with brass top-hats/sleeve (18mm) which are fitted from the ou...
