Re: 1942 RN WNG restoration-Updated 17/06 Handlebars

I think the screw is a cheese head. I will check if I can. It wasn't fitted to the earlier models 36 etc and they could just turn if you hit a big enough bump. The rubber mounts must have been a bit of a problem as the clamp type replaced them. The earlier tapered bars are a real work of art that pr...

You need a screw inserted into the middle part to limit how far they can rotate down if they are a bit loose in the rubbers. Your "original" would have had that. Nev

Re: Daily Fixing and Riding Diary on an Ariel 2019

The steam roller is nice too. When I was young after the council worker had gone home there often would still be some steam pressure in the thing and I'd' move it around Like that one without the rubber tyres. (a Roller) Made in Leeds from memory. lovely smell Coke, oil and steam. Nev

Re: ‘38 Red Hunter on ebay

I just thought I've seen some with none. My first "serious" bike was a 1936 RH 350 which I got my licence on in 1956. I couldn't recall if it had them or not. The bike was completely original till I put a WD top end on it, which one did in those days. It would have gotten Tele forks too if...

Re: ‘38 Red Hunter on ebay

Plate the tank and lower the seat, There's a lot right on that bike. Should it have dots after the "R"and the"H" on the timing chain cover? Nev

Re: Ariel KHA

They went back to an iron barrell and through bolts. A much better set up as the threads pulled out of the alloy barrell easily especially between the two cylinders where the two pressed in Iron sleeves didn't leave much metal. the 500 motor's design never gave any ability to be stretched due the cl...

Re: VB Exhaust valve guide play

I can't see why they can't be fitted. I'm only aware of them running in Fords Cleveland V8 . There should be enough room and it's definitely an advantage at maintaining the seal of the valve on the seat. They don't rotate at any great rotational speed. re the heat insulating washer/spacer above the ...

Re: VB Exhaust valve guide play

Your sidevalve ex valve has a harder job to do than one in an OHV engine. The port and valve temps are much higher. It's also a good idea to have the valve rotate to reduce warping and even out the seat wear. Use a special washer under the valve spring and a valve material that works well on a LPG g...

Re: Aftermarket alloy singles barrel and piston.

I would keep on the lower side of any recommendation as they tighten up when they get hot, and the iron ones don't. I go a lot by feel and there must be no bottoming in the "blind" threads of the nuts. The studs must be the correct length,installed.. I'm not sure about the head gasket. The...

Re: Exhaust blow back

Yes exhaust leaks are the usual cause or a lean idle. The slots in the end of the pipe near the head may be too long or just a bit loose. Engines tend to do this "naturally" to a point especially if you have backed off at revs or saving the brakes down hill with a lower gear.. Richen the i...
