What have you changed since the last time it did not do this? Inflated/deflated tyres etc. Is the only thing the work on the Bramptons?

Head stem bearings not adjusted up enough..........Have you installed a new front tire, if so check that the bead is sitting around the rim evenly........Had one the other day where the tire was pulled to one side because of the rim lock catching the bead of the tire.

My A & B do it at low speed when I'm loaded (over loaded) hold on tight and accelerate through it, never happens when slowing down though. Dropped tire pressures to 23 psi on 21" 90/90 Avon Trailrider on WM4 & 28 psi 19" 410 TT 100 on WM3, dropped pressures from 30psi & 40psi. and more comfortable ride.

Yes, that's what Avon recommend (max for 21" 90/90). My "B" 18" 410 / 80 and on WM5 (3"wide). When teenagers Harvey and I had unpaid jobs in the paddocks of the IOM TT 1966 it looked as if all bikes ran on Dunlop Triangular tyres and they looked triangular except Honda as they had much wider rims, more support also more rubber on the road. When the "A" gets home again and thinking of removing 19" S/S rim and lacing on a 21" WM 4 as the 410 x 19 I had to cut tread off the chain side to clear, I will also increase gearing which it can take as seldum change from top.

Ossie,is your front wheel balanced? I fitted a new 300x20 Speed master once that needed a lot of lead to correct the unbalance.

Many years ago they had a batch that were breaking up, They had a split down the middle if I remember right.
Cheers Bill.
