Been to dyno today for run on my new straightliners pro street class sprinter, Rapido 245cc 60 stroke 72 bore ,v force reed block , 39mm keihin pwk, standard franspeed race, mb head. Barrel porting, boost port and reed inlet by Ben@ AF Rayspeed, head work by Martin @ chiselspeed, casing/transfer porting and built by myself , no casing welding, unfortunatly on the third 3rd gear run one stator plate bolt came out and locked flywheel( had no tools to fix) if not it should have been around 45 bhp hopefully back to dyno thursday and out at East kirkby on sunday.

Nice :)

Does it vibrate like a good'un with those mounts in? I understand the fitting of them for a straightliner but they caused me grief when I decided to give them a go on my road bike. Not faulting it though... very nice.

^... not suggesting that yours is anything like the off the shelf kit but it does show great potential.

The whole body work is fibreglass and carbon, the legshields are single layer fibreglass with the idea they will bend in slightly once speed increases, but keep it looking full-bodied. I really like the Rapido barrel , we have been working on this all over winter , it still has 1.5mm around the indian casing transferes ,and only a little work to clean barrel transferes, massive transferes are not needed , it comes down to exhaust timing / shape and how the inlet is flowed and shaped and casings to allow the flow to be drawn through as smoothly as possible, i wanted to try dyno without the reed stuffer and a higher revving pipe but that will be later in week now. ive took it out for a spin and its going to take some practise to keep the front down to get a good time, if i can manage that it should be quick.

That's a lovely colour. Is it green or yellow in daylight?
