Singles / fit a Victor engine sprocket and primary chain to WD B40
« on: 22 January, 2018, 15:08:43 »
Can you advise if the standard chain will fit with the 28 tooth sprocket from a Victor to improve WD B40 gearbox
Any suggestions as to where to buy from, TSM have the 28 tooth sprocket for 33, no idea about chain.

Thank you

Singles / WD B40 New Amal carb
« on: 15 May, 2017, 22:06:18 »
Hi I am new to site, but could really do with any help
I have rebuilt my 1967 WD B40.
purchased a new premier Amal 626 carb, which was set and jetted by Amal, along with one of their cone air filters
The bike starts well on the choke and warms up so choke is off.
The problem is once the bike gets hot it will not tick over, stalls and is hard to start.
Trying to reset the pilot jet and tick over ends up with the engine racing and cutting out.
I have tried running the bike stopping and adjusting pilot and tick numerous times
I have checked timing and valves several times, new points and condenser, bike has new coil and wiring, battery . It runs on a power box instead of rectifier and zenor.
I am not new to classic bikes , but first time with the  new Amal carb.
Contacted Amal, they suggested bigger pilot,  this did not help the problem
My day bike is a 1987 R100Rt BMW and I can get that ticking over down to 800rpm without any problem.

Advice please before I send it back to Amal and rebuild the old tired one it ran on before.
