Twinshock

I have an old Cotton Bogwheeler that I am trying to restore. Does anyone know of any parts suppliers? Thanks Much! Retro

Hi I've got a Merlin DG 350 twinshock which has a worn out carburettor,do I go with a new one the same as the original or try something else? If so what has anyone tried and tested.Any feedback would be helpful. Also what's the engine spares situation like if I need anything at a later date. Cheers.

Will the carb and front forks from a 349 work on a 348.

100 quid seems ok http://cgi.ebay.it/Moto-Ricambi-e-Accessor...id=p3286.c0.m14 if your italien is like mine try this site http://www.linguatec.net/onlineservices/pt/site HTH lee

Anyone tried them? How do they work? Are they better left to the MX crowd?

Hi, Does anyone have any info on where you can find these elusive shocks, site has been down for weeks!! Is there an importer? or shop that has them? regards, Ian

Just bought myself a new (old) toy, a 1983 Armstrong 320 (what i packed up on when i was but a kid) with the Hiro engine. And wanted to know what fuel i should use (i use Shell Optimax in my 315R), what ratio of fuel/oil mix and what oil to use in the engine ? Any tip's and advice (excluding "sell it !"), and help with spares would be much appreciated. Thanks in advance. Gaff.

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??

Does anyone know the frame numbering sequence for the 340 Sherpas modified by Comerfords?. I saw a 340 recently that looked like and was claimed to be a Comerfords bike. It had the forward top mountings for the rear shocks and the larger s/a mounting plates to take the swinging arm forward to within a few mm of the engine casing but the swinging arm itself was of heavy oval tube and I thought they had rectangular ones made by Whitehawk. Or maybe that was an extra?. How many 340s were made in total?. Sorry, must have pushed the go button twice or something, maybe Andy can remove this post, please.

I was wondering what the rules are for twin shock? can i run disc brakes? I have a little 125 scorpa that i really love and dont really want to get rid of can i make up a rear subframe and bang two shocks on or is this not playing the game? I have seen a lot of big money bikes that seem to be accepted

Hello, Does anybody know the weight of a TLR250. They look small and light but I rode one recently and it seemed just as heavy it's Spanish rivals. Thanks, NAT.

Why did Bultaco and Montesa go under ...Was it the Fantic 200??. I know that Mr Ignato Bulto set up Merlin so his enthusiasm was still there. I know that Spanish companies get big tax breaks for the first 2 years, keeping Mecatecno afloat. A lot of these companies were set up by enthusiasts and not business men. Maybe thats got something to do with it?. Anyone know?.

I've got an Armstrong CMT310 with the HIRO engine. I bought a photocopied manual from Sammy Miller which is little more than useless, I was expecting a proper workshop manual with technical info. The bike starts from cold after a few kicks and will tick over etc and starts first kick when warm, but seems to have very little compression for a 310cc single- I can turn the engine over by spinning the flywheel with my hand- surely that can't be right? I understand the spares situation for these engines is fairly hopeless. Has anyone else overcome this situation? Is there a piston that will fit from another engine? Does the cylinder have a steel liner insert or is it a pla…

It's struck me during last year that the classic road-events don't always have a big twinshock following; maybe its because the riders don't have bike licenses ,but also its that a lot of twinshocks weren't originally road registered as more events went off-road. There's been quite a few postings on this subject on TC forums. So, I've written a short HOW-TO guide on getting a twinshock MOT'd, dated, insured and how to get a registration certificate. I've used this for get an age-related number plate for my SWM Jumbo that I've just finished working on. Let me know what you think and if its useful (and correct)

For those who are interested On a dutch site there is a complete Ossa exhaust system for sale (it is not from me) http://link.marktplaats.nl/258496000

I have a 348 that when I start the engine runs really badly and bogs on rev. The eventually dies. The fuel is at 33:1 the scew has been at 1.5 turns and in lots of other places. Carb has been cleaned. New Spark Plug used. Any ideas, more the better so I can keep trying things. Thanks

I asked this question a few years ago with no answer, but maybe this time I will get lucky. I bought a few basket case TY ( A, B anc C model ) with different rear rim width: 185 and 215. I ride the 215 rim with a Michelin X11 and bought an IRC tr11 as a spare, I would like your input on this : should I mount the IRC on the narrower rim or change the Michelin to the narrow rim, or is it a bad idea to mount a tire on the 185 rim? I hope someone who tried this can give me is input Guy

Looking for the best oversize lining for a TY175. Drum had already been machined. What material do I need and who can machine the surface. any suggestions?
