Re: Dynamo not charging

When I recommisioned my '53 VH after sitting in the shed for some 30yrs, nothing I did could encourage a good charge from the dyno. Before being laid up, the bike had the best charging rate I'd seen on a 6v system - you could even take it out at night! A few pointless hours were spent prodding and p...

Re: square 4 HEAD STOCK BEARINGS RACES

I think Drags do a taper roller set up for that. I would advise that you grind or file a half round relief on the seat in the frame as the bearing outer is considerably narrower than the original. Don't ask me how I found this out....

Re: New member, '52 VH500

Both of my front mudguards on 53 VH's have the same fractures as yours, and the tinworm! I'm in the process of cutting out a section on both sides and welding in new bits, a right faff. To strengthen the lot I've made a bridge to go on the inside, locating inside the beaded edge that I will then wel...

Re: Balance factor

Before this thread gets too old, I got back to the flywheels. with or without the additional weight for the oil, the T/S flywheel was a fair bit out. As Nev says, there must be some oil in there, so I've included the 8gm in the calcs. I noticed on an old forum post by Mr Brenton that his balancer al...

I bought this one last year. It's an inductive sealed unit, under a fiver, seems pretty acurate on my single, can be reconfigured for twins or fours.

Re: Balance factor

Interestingly a friend has given me his '52 NH crank to balance. After doing the sums and making the weight for the flywheel, the drive side flywheel was spot on. The timing side is all over the place. I may be making a rod for my own back however. I've calculated that if the sludge trap drilling is...

Re: Lodge plug

I switched to NGK's many years ago, with no regrets. I used to run a service station in the U.S. the amount of dud Champion plugs was quiet significant. I attended many rallies both here and abroad, clocking up mileages approaching Mr Carters. I found that the electrodes on Champion plugs just plain...

Re: Balance factor

To add to the confusion, from what I have read, would the balance factor be different between the single downtube frames and the later duplex frames?
