Re: Fiberglass mudguards

The AUD is very low. Makes it better for you and worse for us to buy from anywhere. I don't think anyone will be getting rich making guards for a large number of " different" old bikes. Nev.

Re: Concentric carb on a Mark 1 square four

The square is the only butterfly throttle carb you come across generally on Ariels but all butterfly carbs must have the idle passage holes uncovered at the right time to operate in the range near idle. IF there's any wear there that may be out of whack. Bushes and the dimensions of the butterfly it...

Re: BA Gearbox Problem

Chris, the layshaft float certainly may affect the depth of the engagement of the driving dogs. My answer to what is good is minimum safe, which I would see as about .010"( 1/4 mm) With new bushes /cases I've found without the gasket, the box sometimes hasn't enough end float. I've been fitting...

Re: BA Gearbox Problem

You can get wear on the pins that are in the selector forks and wear on the fork faces themselves and excessive end float. The usual causes of flying out of gear is not going into gear enough or faces of the engaging parts worn off a bit or worn tapered . Mismatching of some model's parts can make a...

Re: Fiberglass mudguards

Fibreglass on motorcycles is not new. Bultaco's had plenty of it but it's not the magic fix. IF you have nothing else available, sure go for it, but it's one of the reasons I don't work on bikes like Bultacos… Mudguards have stays and sometimes hinges and are a part of the structure often. Good plas...

Re: rigid crank versus swingarm crank

Taking flywheel effect off (reducing it) can make a bike much less pleasant to ride and require more use of the gearbox at lower road speeds. The Balance factor may change with the type of frame as frames have their own natural FREQUENCIES. . only the NH before that late type wheel came along is ste...

Re: 389 Monobloc Leaking

Brian, Monobloc's weren't much when they were new. The concentric is a much better thing to get right. Nev

Re: Fiberglass mudguards

Can't say I would go for fibreglass guards myself. Think I would spend a bit of extra time on the steel ones. Nev

Re: '52 VH500 rear tyre size

350-19 is OK on standard WM2. 400 is best on WM 3 but a light 400 might be ok on a WM2 It's not ideal but I can't see why it would be unsafe See how it goes. There's a light 400-19 MITAS tyre available. Nev

Re: '52 VH500 rear tyre size

If you want a good ride use the biggest section that will clear the chain and run it a bit softer. 4.00 is fine and I'm using a wider rim when I've been able to get them 350-19 is ok on the front also., Nev
