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?

Period Tax Disc

Item number 293357001153
For the anorak. Period tax discs 50% off, £2 for a stocking filler, and a helpful guy too. Just remember if your bike was registered in June '52, you want an expiry of Dec'52 or June'53. No relation, etc

Re: F cam reprofiling

I am suprised that chrome plating survives on cams and followers due to the scuffing nature of the application. Just a gut feeling. There must be a smallish limit to the amount of wear that can be compensated for using this method? The stelite hard facing method does fuse to the parent metal better?...

Hi Klaus, Don't know if you had seen this or not. There is a link to the Draganfly page. Hopefully Lee has sorted this problem now. I have been holding off ordering a new cable until then

Re: Twin leading shoe brake queries.

I also tried turning the shoes to size. Low speed, sharp tool, small cut. They still managed to escape. After an underwear change I wired the B****rs on!
Stay safe,
Paul
