Hello,
for my TT1 replica (with 36 mm. phf's) i use a Domino race throttle:

On the racetrack it costs me a lot of strength to fully open the throttle at the straight part of the track.
Due to a heavy slide spring (i'll get a lighter spring), but mainly due to the long stroke of the throttle. I have to take the throttlehandle twice to fully open.
Does anybody know a better twin cilinder throttle with a (much) shorter stroke?

Thanks!

William

They are pretty hard to find but the TZ 250 throttles [late 80's] work really well. Less than 1/4 turn with 40mm carbs.

Meade Speed has replicas. Lou
