Dual Disks

[dr442]

Hi, Anyone know the bolts to use from what  bike to assemble a dual disk on the 1970 cb750. Also what speedo drive and the dual hose valve at thr lower tree?

Thanks,  Craig

The bolts do not come from another bike. You take the original ones in and get the same pitch and size, just longer.
For the speedo plate on the hub, you need a 500/550 plate.

After the pressure switch, you make it a dual hose OR you get yourself a newer master as you kinda need to anyways. The original master does not really do the job but if you want to stay somewhat period, get a goldwing master or a 77/78 F master and either get a longer banjo and do 2 separate lines, OR use a gw or 77/78 F line setup.
