can anyone tell me that if i hold the back brake on and rev the swing to 2 to 2500 before pulling of am i looking at doing loads of damage to parts or am i better bringing it to around 2000 with no brakes on then launching i like to get in front of the cages cant teach a old dog new tricks

I don't think either is a good option. If you consistently rev it with the brake on, I believe you're going to cause some damage in the long term. Maybe I don't understand but how can you rev a Silverwing without brakes on?. With no brakes, as soon as you roll on the throttle, you're moving. From a stop the Silverwing will out accelerate most cars on the road pretty easily.

I don't do it from a straight away takeoff, but i use the brake to "feather" the power when turning from a stop. When the clutch engages on mine it seems kinda lurching, for lack of a better descriptive, and i like to control that with the brake when turning. The way you use the rear brake when doing slow speed turns. I don't see it hurting anything.

Just remember.....When you are using rear brake as balancing aid or "clutch" in turn from stop......YOU are also putting the front brake on! Linked brakes.....think sand. I am now on 4th Honda with linked brakes---always think, though, what could happen. To date, even in snow, rear comes on first, thus not having front wheel slide or tuck in due to lack of traction. BUT?

I prefer brakes that are not linked. Helix with its wonderful foot brake, great in Tokyo traffic.
