Re: Replacing a VB tappet guide

It might have a slight shoulder on it and need to extract upwards. This can be done with a suitable bolt and nut washer and sleeve and you might even be able to put the new one in the same way. (in the reverse direction) Nev

Re: Removing the ringds from a VB piston

Heat is best. Get it pretty hot especially the top and prise an end out. You may end up breaking it into a few pieces but try to have it up a bit before each section breaks, to allow a small screwdriver or such to get under what remains. Nev

Re: Grades of Steel

It's free cutting. Not very strong or hard. You might have some difficulty getting the steel in hex that would be the best for the job. You could carburize it or adapt a vehicle wheel nut if it's 1/2" x 20. Alter the taper. If it's full width thread it's not really likely to strip if the fit is...

Re: WNGs found in Normandie

He has the correct exhaust pipe clamps. Koala stamp for that. I don't think you run a dip switch when you have the headlight shroud.. It only lights one beam and the park light First time I've seen the contract number (the plate on the rear guard) sitting LEVEL. They are usually drilled all over the...

Re: Ariel twin

Same as the singles 65% but do it dynamically as the shaft is fairly wide. This requires special weights to be fitted to the crankpins. Pretty similar to the early speed twin/ tiger 100 triumphs.. I will have to get around to doing mine some day.. (and cleaning out the oil galleries.) I have a few s...

Re: Ariel twin

Mine was a bit of a shaker when I rode it a few Kms years ago, but nice otherwise. People rebalance them and they are OK. 500cc vertical twins are usually not too shakey. When they get bigger they are . Like the commando's 850 set in rubber mounts because you have to. Nev

Re: Oil pressure regulator thread size

IF you expand it you will be in strife. Use heat first to try to ease the tightness. Nev

Re: Oil pressure regulator thread size

Yes to the wire. but wayback. I've had more trouble with the squares being rounded off and can't get them out. They don't HAVE to be ridiculously tight and the early and later ones are different. with different springs. Big cause of pump failure. Early ones have tapered springs. Real trap for the un...
