Twinshock

Hi, I've decided to join the twinshock gang and have gone for my teenage favorites. I had several Ossa's as a schoolboy and owned a Gripper back in 1981/2 when it served me well. Trouble is I don't really remember much about the bike and need some help with basic stuff like fuel mix, plugs, gearbox oil etc. Bike is basically ready to ride and hopefully will get its first outing at Oxenlaw on Saturday. I'm looking for an "expert" who can answer my daft questions as and when they arise and offer tips on set up and maintenance. It would also be nice to know how many grippers are being regularly trialed, I haven't seen any in the North East. Thanks, Gary.

what combination of parts do you think would make the perfect twinshock? eg fantic 240 frame, ty 250 motor, beamish forks, ossa back end, obviously leaving real world parts compatability out of it. just for fun what do you think

Hi all, i`m trying to trace the history of my 83/84 armstrong hiro. Its head and barrel have been drilled both front and back?? and it has been fitted with number holders on the silencer and left seat rail. Its reg is A504 UAE if anyone recognises it or can help. Its a fit old bike with loads of grunt and once I get the leaking tank sealed i`ll be using it instead of my fantic so it would be good to know its history.

21M25425 Has some different stuff from my '74 which is also a 21M. Clutch arm on top, different engine covers, Amal carb... The guy I got it from tied it down to bring it home and when he took the straps off, the forks stayed collapsed. Any Ideas. The seat/tank is a WRECK. What are we doing with these things these days? I still figure I did OK. Buying bikes from rednecks is interesting. He took $375 and a 30-pack of Busch.

Hi all, Is there an existing up and running- or is there interest among clubs/national org.s of establishing a TS Europe cup (pref together with Pre-65)?? Or even Europeen Championship like the motocross-people arr.. I might have missed this discussion..

Hi all, I just wondered if any one knows how to work out the length of spokes needed for a wheel rebuild? I am trying to rebuild a wheel that had a 17`` rim on it. I am now going to try and put an 18`` rim on instead. As the hunt for 17`` trials tyres was proving to be impossible... Many thanks in advance.... Pete.

A real corker here http://cgi.ebay.co.uk/Yamaha-Majesty-175cc-Trials-Bike-/320659869551?pt=UK_Motorcycles&hash=item4aa8d14f6f Looks lovely...................I'm going to put

hi i have an original 82 majesty 200 witch i need some info on. The fly wheel and crank are both scored pretty bad and keep sheering the key. From my understanding they both differ from a ty 175 so what did they use and where can i source parts. Is the piston the same as the 200 kits for the 175 if not what is it and where can i get one (i heard its a 250 piston with skirt cut down) the swing arm axle is striped i have a 175 one in there thats spaced out but gets in the way. i guess i could thread it down and cut it shorter but if i want to put the 175 back together i kind of need it And if theres any other usefully info about this bike i would like to know about i…

Hi PASTED IN FROM CLASSIC SECTION Well I have got the new Mikuni VM26 set up with a 150 main and 30 pilot. Starts pretty good, and runs cleanly but it is now missing when it gets hot. I am running it on 33-1 and with the air screw by 1.5 turns out. Rubber inlet hose in good condition with no leaks. Looking at the plug I have noted that the NGK BP-7ES look pretty hot (ie no hint of soot, and a copper hue). Could this be the problem. Any thoughts of the next step to get the bike running cleanly. Is it worth changing the plug (to what type?), revert back to 25-1, or backing out the airscrew. Or all of the above! Thanks in advance Chris Posted 13 September 2011 - …

Hi , I have my first LDT this weekend. Feeling nervous. Having spoken to the organiser she assured me i'd be ok; there is a small girl riding a big bike staring behind me and she is ok. I am a big bloke on a small ty175, i think i will just look funny if nothing else. Anyway what should i know? Any tips? Biggest question is tyre pressures - do i have a set pressure for the day with road work and sections, or pump them up and let them down as i go - and what pressures should i use? cheers

What's the way to go with this? I have a crappy, dented delaminated tank. I don't need beauty....just keep the fuel where it belongs.

Sprite! I think this model may be called a Goldfinger but I could be wrong. I'm a real sucker for these British kit bikes

you know how it goes.......a friend of a friend knows this dude who has a trials bike fer sale,made out like a bandit three Tl125's for a song.....100.00 each.even managed to get one fired up tonight. My best purchase so far.

Does anyone know anything about the early development Suzuki prototypes of Gordon Farley? Or have any pics? There's one pic each in Don Morley's "Spanish Trials Bikes" & one of John Hulme's volumes of "20yrs of Twinshock Trials" & a couple more with a little info in another magazine on trials, but not much. Of the few pics there, most look like modified TS250 engine & prototype RL chassis, but one looks like its a SherpaT rolling chassis w RL engine & tank (said to be in 74). Its certainly a Bul front end. Also, an interesting bike has turned up in Canada: a Suzuki engined SherpaT (maybe Miller frame) with the interesting engine # TS-T-00001 Is Go…

When I got my TLR200 it had all the lights, speedo and ignition switch installed and so I removed all of these except the ignition switch as the mounts had to be ground off in order to remove it. I have just been doing a tidy up and I had triple clamp off and so I decided to remove the ignition switch and what was left of the wiring harness. Now it won't kick - completely dead. I have had the bike complete stripped engine out etc I can get measurable power (multimeter) from black/red lead from the alternator and there is only the green, black/white, black/red and blue/yellow and plain black leads from the CDI - should be simple but even with the kill switch disconnect…

Finally,I have got round to staring a project I've been thinking about for ages.A long time ago I bought a totally stripped TY175 - because it was there. Then started looking around for an XT225 Serrow engine to go in it,couldnt find one.Last week I took one in to cover a bad debt.My idea is an alternative to a TLR,(which look nice but I could never ride them any sense)but with the added bonus of electric start. Tonight I cut the frame around enough to get the XT motor in and started sussing out measurements for engine mounts etc.Its a bit of a squeeze but it will work,and so far looks like it will make a nice bike.Anyway reason for posting is that the biggest problem I …

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 All might be one for big J looking for information and photo's of the late 60's Diamond trials bike,the only information i have found to date is in Mr Morleys british two stroke book and there is no photo's I have aquired a frame which i was told was a Dalesman which i don't think it is,on rubbing back the paint work the frame looks to have been a pale blue but the rear chain is adjusted by snail cams on the swinging arm pivot it has prop stand mtg bracket on the R/H side the frame is also twin down tube forming a cradle under the engine,engine mounting's look to be for a sachs engine.It looks at first glance like a rickman but they were nickle plated or possi…

My TLR 200 had a badly rusted tank when I inherited it 12 months ago. Initially I tried the molasses treatment - 10 days submerged improved it but it didn't really control it so I fitted inline filters and became used to cleaning the idle jet. I have since tried other rust converters but once you rinse them out it is rusting again before the rinse water dries. However riding with a mate on his very sweet Bultaco M125 a few weeks ago and he was going through the rigours of draining his tank after a ride because of ethanol concerns and this made me a bit concerned about what may be happening on my Cota 247. So I decided to try and resolve both issues and I found an Aus…
