Twinshock

On my 349 I need to replace the gearbox bearings, two of which are in blind holes.... I have been told to support the case, behind the bearing, heat the case, and jam in the heads of a couple of large nails under the bearing to lever it out. Anyone got any further tips? Thanks Steve

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

Gearbox Shims on a Mont 349

I'm riding 1970 Montesa Cota 247. I'm beginner and stating to compete in vintage trails events, meaning riding in woods. My bike has 10/48 sprockets set. The Cota manual indicate that the factory bike has 11/46 set. The difference is about 12%. But what does it mean? My main goal is to ride as slowly as I can in 1st gear and maintain smooth acceleration when needed. Does the 11/46 ratio is slower then 10/48? Should I changed back to the factory setting?

A short Youtube film showing a brief history of trials and George Silk explaining his new gearbox-probably from the 70's?-a 4 speed with high and low ratios.Does anyone know of these Silk machines today?Engine seems similar to the Alta Gaunt Suzuki in the previous thread,the bike like a Montesa.

please Help. I am desparate for an original shape TR80 Gripper Kickstart Lever. Can anybody help ?. Many thanks Peter. glamourgirl31@manx.net

Hello people, This one might test the old dinosours (like me) out there. I have bought the above mentioned Gilera and was told it is about a 70-72 model trial/trail (I really don't know much about them). It has a four stroke motor, lights, electrics etc and I am wondering if anyone has any idea where spares can be obtained. I will try to post some photos once this camera of mine recharges its batteries, Thanks

Acquired this today (from a kid I met round at a mates garage..). Cost

.... but over

Just started to build a 175 Majesty using a godden frame. The 175 motor slots straight in but the head stock is a different size to the standard 175 frame. Anybody know what bearings would fit to enable me to use the standard 175 front end? Open to any ideas on the solution, plus suggestions on exhaust systems. Thanks

just finished my latest project -

Thought you might find this pic interesting. It is Clive Dobson (500t in the Talmag and Scottish) on the 4 stroke Gollner Kawasaki at Horsham clubs Presidents Cup at Plaistow early 80's. I believe only one was made that started off as yellow then became red, apparently the engine wsa pretty standard KL with some KT ratios modified to fit, nice bike tho'.

I am looking for some pictures, preferably colour for a friend of mine in France to finish off a Gollner Kawa. Also is anyone currently using one in twinshock trials and can they tell me what rear shocks you are using. Thanks

Can anyone advise me of the correct colour, or even remember what sort of yellow it was. Light dark sickly stc

sooooooo is there any way to get the frame specs to build a gollner framed kt250(aka The "peril")? dgraf

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

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…

If I had the money I'd buy it: http://cgi.ebay.com/ebaymotors/ws/eBayISAP...item=2460778227

aahh, the frame made it back from the powder coaters(sweet!) I still need to figure out how to shed some weight off the beast(without going illegal in the twinshock class) any help would be kewl my kt250 is almost ready for its 1st trial.
