Twinshock

Does anybody have a contact for Betor Shock Servicing and/or supply of heavier rated springs?

Can some one tell me who it was making the Thump twin shock frames? Was it J.Reilly?

last year I wrote an article about getting my SWM Jumbo road registered. I am currently getting another bike done and there have been some changes required by the DVLA. Specifically, organisations that provide dating letters, now require photographs of the engine and frame numbers. I have used Roy Bacon for my dating letters for the SWM's and he kindly contacted me regarding the change today. The updated article is now on my website.

Hi there, can anyone explain how to correctly set the Float height on my 1977 Ossa Bing 26mm Carb There is a brass plate attached to the float which can be adjusted to get the right shut off but im not sure what the gap should be, Cheers, Vaughan

Hi does anyone know where I can get a decent timing side cover for a Montesa 248/349 white wonder. Thanks in advance Mark

I have a pair of original alloy bodied Rockshocks are they worth a rebuild ready to fit to my Cub, or have shocks moved on so much that it would be better to get a new pair.

Hi i wonder if anyone on here could tell me the the measurements of the holes of the above fork braces, my measurements are 120mm by 64mm it would be much appreciated.

I'm just about to order some new fork seals and was wondering why there are 2 in each leg? Is it because 80s seals werent up to it? If so I would fit only 1 to reduce friction???? (with suitable spacer). Ian

Hello there I have a Bing 84 fitted on my 1975 Sherpa which needs new gaskets and O rings, but the price I found online is the same as whole new carburettor! Therefore I’m wondering if: A. Is this is the right carb for the bike? B. Where I can find a cheap rebuild kit so it runs properly? C. Can I put a new carb on it? I don’t know much about this bike so any help is much appreciated. Thanks Tom

What type of engine oil should i use for my Cagiva DG350 twinshock. 1983. Does any one have a clue as to the oil capacity. Thanks in advance. Have some 10/40 Castrol, would this be ok.

Can you get progresive springs to fit older Falcon shocks? I have tried ringing Falcon but never any answer? will Betors new progresive spring fit ok?

Can anyone tell me the correct ohms reading on my '67 T20M ignition coil? I read 1.8 ohms from ground to input lead on the secondary. (all wires disconnected). Also I would like the reading from the 5 alternator wires. I have a black/white, black/yellow, brown, brown/blue and red. I get now spark at the plug. My bike has side points and no battery. I have a repair book but it is no help. Being a positive ground system, will any other single coil work? I want to keep the stock ignition system because my bike is street legal. Thanks,

Does anyone know how much a 1982/3 Montesa 349 is worth?

Ty 80 red frame numbers on frame and engine 451-406876 dose any one know the age

The chrome springs of the original Betor shocks are badly rusted so obviously I have to get new shocks for my Montesa Cota 348. What shocks work quite well but are not very expensive? How important is the rebuildability? I think it's however quite expensive for me to get the shocks rebuilded abroad and I suppose the finnish shock repairmen don't have spare parts for this kind of shocks.

I just finished putting my '76 KT 250 back together, however I can't get her to run. Rather she starts 2nd kick, runs about 10 seconds with the choke on then quits. I've tried fiddling with the mixture setting, no luck. Good spark, good fuel supply to the carb. Suggestions??
