Twinshock

HI can anyone suggest a way to flush out the gearbox on an SWM 240? i was just going to do two oil changes close together but was told to "fill it with diesel give it a swill round then drain it." Has anyone tried this? Thanks Matt

I've noticed quite a few MAR Ossas have had a weld repair to the ignition cover which seems to run diagonaly from near the rear top scrw down to just above the rear brake pedal. Mine has also. Why is this? Is it a weak point? Can you do anything? Dont seem to remember a problem in the early 70's Also seem to remember everybody cut them back as much as possible to help with cleaning and chain maintenance. So why do so many show signs of being welded?

Recently acquired a 1983 CanAm 320t / Armstrong-CCM 320t, (this is a Hiro engine bike) which I hope use for twin shock events next year. I need some parts as listed below, any help locating is appreciated Front and rear brake shoes Fork seals Front and rear sprockets Engine seal kit Gasket set Air filter Clutch, front brake and throttle cables

Just that really has any one tried these shocks yet, what do you think of them.

Hey folks, I am looking for magneto for armstrong hiro 250, or would any other magneto fit it as long as its ok for key & shaft? any info would be great thanks in advance.

Hi, can any one tell me what is the best colour match for a Montesa 200 Cota 82/83. I have just got VW Mars red, but it just don't look right. Also, i need a complete rear brake assembly. Thanks, Ian.

Any ideas where I may find an airbox rubber for Montesa Cota 348? The original one is worn out.

Can anybody tell me how these bikes compare to other twinshocks, which is better 250 or 350, any mods that are done to them? Many thanks in advance.

I gave my TLR 200 a bit of an overhaul and face lift - fresh fork oil, new brake shoes,grips, sealed the rusty tank, a fresh coat of paint and I am very pleased with the results but looking at the photo I see what I forgot... some air in the front shocks ... doh!

Hi does anyone know if it is possible to make the pull on a 248 clutch any lighter, cheers Mark

Hi Guys/Gals I have two good prospects for my first restore/mod project. '76Ty175 in excellent condition. Pre '66 Triumph Cub set up for trials with spare frame wheels etc, runs well seems all original Heart says Cub head says TY. Any and all thoughts appreciated. Thanks. Jon

Hi I just noticed my front brake lever is cracked - not surprising when you see the bend in it - but I am not sure what to replace it with - is it the Amal 534 and are the reproductions breakable rather than bendable? Can anyone suggest and Australian or UK supplier who will post to Oz

Hi I've just bought a bike and have stripped it to find what needs replacing, its has a new Domino throttle and cable, as I'm on quite a tight budget I was hoping to use these again. Is there anyway to tell if it's a slow pull or fast pull throttle. Thanks in advance

would of said "you lucky people"..... found this whilst browsing, thought I'd bookmarked it, then lost it and took me hours to find it again. A 'Which Bike' test of the 1978 Monty 247 which I now know was called the 247C, the 'C' standing for competition. So it must be suitable for trials I guess cota 1.pdf

This is a '78 (I think) 247 and the forks seized. I got the first one apart, but it wasn't easy, and some stuff dropped out...like a rubber seal and a snap ring! Maybe if I'm really careful, I can get the other one apart and be sure how to put them both back together. Also...I know that there are some aluminum bits that bind. Could someone tell me what needs to be done to get these working smoothly? And if someone could lead me to a parts diagram... Thanks!

Have heard from some old timers That they took the swing arm from the 348 and switch it with a 349 swing arm suppose to make bike handle better by making wheel base from 51.5 to 53.2.Has anyone tryed this or think it would be worth it.Have heard that the 348 had a light front end and this was suppose to help????

I am rebuilding a Montesa 242 and although the bike is low hours and relatively untouched, when I washed the clutch case and gearbox out with petrol, what looks like thrust washer dropped out of the primary case, evidence as you can see, a ham head took the clutch apart, the nut was also loose, has anyone any advice on dismantling these clutches please? Many thanks 242.pdf

Hi, anyone got a manual or know the ring gap and piston skirt to liner clearance as i have located an oversized piston (ebay) and its winging its way over to me. I have got the barrel mounted on my old van norman boring bar ready to go as soon as the piston gets here and i can give it a good measure up. The barrel was on its second bore and the piston was standard!!! and it had a fair old rattle to it, its amazing that someone would put an engine together like that. Cheers Dave

Another brill trial, this time at burycliffe, near Elton Matlock, seem to get good weather for all of Paul's events, have you a connection to someone up there?? Anyway thanks for a great event, good turnout as well...bonus! Regards, Ian
