Twinshock

Saw a pair of rock shox for the first time at a trial today and they look just what i need for the James. Asked the guy whose bike they were on where he bought them "from the bloke who makes em". Hmmmm not much help. I seem to remember reading somewhere that Pete Edmundsen is doing them but cant find a number anywhere. Can anybody help with a number or website?

Hi im interested in adding a 1979 montesa cota 250 to my collection i remember my cousin having one back in 81 and it seemed a stonking bike , really zippy revved well? would this be badged as a 247 cota or a 249??? were they any good i remember it being superier to my 76 ossa at the time though i suppose it was a much newer model better tech, etc!!! only real problem i suppose is actually finding a good one only ever see 248 /349's and earlier 70's cotas but never late seventies 250's cotas WHY? imho the above bike looked stunning! but this was 26 yrs ago!!!

Hi guy's i thought i'd start a thread on hot tip's for restoration! as i know a lot of you out there are doing up pre-65 and twinshocks! This would be to everyones benefit helping along a restoration , so heres the first tip, when youve got that old trials bike back home and its looks like its been dragged through a hedge backwards a few times, get a handfull of wire wool and squirt baby oil (yes dont laugh) all over the grimy stuff and rub it well in , you'll find that this will clean up the bike a treat and wiped down with a rag with the same stuff will protect it! ive just done this to a pair (wire wool) akronts and they've come up a treat! everything else i tried …

I had a problem with my 200 Fantic running 'rough' missing or 4 stroking is the only way to describe it. I found a partialy blocked pilot jet, could this cause the problem described?

Hi all, this is my fantic that i built specificly to compete at a harder level than just the clubman route, although i did ride it in a few twinshock / pre65 trials this year, you will do well to spot all the mods, and it is 100% fantic, i now ride a TYZ as my main bike so this one is redundant :-( I would be interested in any oppinions Alan http://img87.imageshack.us/my.php?image=24102006171yg2.jpg http://img133.imageshack.us/my.php?image=24102006172mr1.jpg http://img83.imageshack.us/my.php?image=24102006173mi4.jpg http://img133.imageshack.us/my.php?image=24102006174qc0.jpg

A little tanned man left this on my door step today............ Can you guess what it is yet. Yes.......... i know its a bit of a nail at the mo , but you just wait and see . Exact answers only please.

Anyone got any colour pics of an original Gollner kt.I am about to rebuild one but there seems to be very little info about them. All info / photo`s would be greatly appreciated. Paul

Cost of machine and ease of getting hold of spares, ride quality etc etc.......TLR's need not apply due to the high cost of the bike on the s/h market.....am i right in thinking along the lines of TY twinshock (250?) of Bultaco 250 / 350.....any comments gents?

Any one have any comments on what would be the best forks to retrofit and still be pre 1980?

Can anyone help me to date my TY 250 and any other info as to its Origin, Is the White frame original. I have included a couple of photos if this helps. The Frame number is 498-801910 Cheers, Vaughan.

Doe's anyone remember this shop back in the seventie's, what bikes did they sell? and did they support local ace riders? i think my ossa mar originally came from there as it had the little " castle" stickers on the side panels( it came from burham/ taplow area, we lived in high wycombe at the time!) some pic's would be great if anyone has some? Nick

I am trying to rebuild a pair of betor dampers which I think came from a late Bultaco 340. Does anyone know the amount of oil and viscosity, and if there is any chance of getting new seals?

Forget little 200 Honda's, how about xl500 power!! Seen on French ebay

I know this sounds wierd but ive got two ossa mars both same year mk11 250's the engine numbers are about 300 away from each other! standing from the rear of each bike looking straight down at them one has the engine offset by at least 1" to the left the other bike the engine is dead centre! what the f**k's going on with this , anyone know???

I looking to buy and restore a twinshock yamaha TY 175/250 Have found sites selling basic parts .But what about engine ,gearbox and clutch parts are they still available if so where ?Help please regards phil

Hi maybe some out there can help. I am rebuilding a Cota 350, which has basically the same engine as a 349. I had the crank rebuilt and the rod used is not a Montesa original rod but a Metrkit rod which is aprox 1 mm thicker in the rod width, the base and top being the same as the Montesa rod. I recentered the crank using some of the different guaged spacers, and got everything lined up with an even distanve between crank halfs and the rod centered in the middle of the crank cases. Everything seemed ok until I put the piston and cylinder on and there is a noise as I turn the engine over. From what I can see, the connecting rod is shifted to one side as the engine turns a…

Hi chaps im restoring a ossa mar 1976 mk11 , ive aquired the correct amal 627 carb for it, but when fitted it will not flood on the tickler,the fuel flows ok and theres fuel in the float bowl but when the tickler's held down it just wont over flow so the bike wont start? also im tryng to save the original IDEAL fuel tap but the black rubber tube inside has perished? anyone got a spare or knows someone who has? cheers Nick.

Fancy doing something a bit different, I've seen a pic of a fourstroke engine in what looked like a TY twinshock frame, lovely looking machine. I understand you can buy Chinese engines (Honda copys) off John Bliss for right money, I've heard one of these engines running and it did sound very sweet. Has anybody put a fourstroke engine in a yam frame?? any major problems? Cheers Mark P.S don't want a TLR, just fancy something different

I have recently got hold of a 159 which has been stored for a few months but was definitely a runner (and I can trust the guy I got it from). If I crank it over with the plug on the head I can't get a spark. I can't see anything obvious, the points check out with a multi meter and have tried a spare ignition coil which made no difference and have also tried more than 1 plug. For the wiring into the 'chocolate block' is it correct that the red cable from the flywheel magneto goes to the black lead in the ignition coil? Any advice gratefully received.

What is the trials scene like in N.Devon I ride twinshocks, some SM rounds etc. Thinking of a possible move to the Barnstable area. How far would i have to travel to get a ride? Which is the local club? any info appreciated.
