Hi all,

I think this one may be one for the specialist tuners amongst us, I know a few dafties will come up with the answer "why don't you use a HW seal as they're the best" but can the standard later parachute style BSA 29mm piston seal that's fitted to the Airsporter RB2, Supersport, Superstar, Goldstar be improved upon (probably knowing BSA) or are they pretty good for what they are? I know V-mach used to do them (they still might do) in their C form type seals but would it be worth the expense and hassle of obtaining one if the BSA one is adequate enough for the job?

Your thoughts on the matter would be appreciated.

Cheers

Pete
