It's a Gas gas one - the standard yamaha boss is used and it was all converted by Craig Mowlem

Here is my TY250a It's a long way from being 'finished' but it's slowly getting there. Not had a chance to ride it with the new exhaust and forks that work ( well I hope they do )

Very nice - and the front brake is interesting. What is stopping the backplate from spinning round ?

Hi Mattylad Thanks for the reply - any chance of a pic of your airbox ?

Hi guys I am sure I read somewhere about using a Montesa 315r on a modified TY250 twin shock airbox I have seen the one on the very cool highly modified TY in one of the mags and on here but that uses a custom airbox and I want to use a standard ( but of course modified ) airbox Has anyone done this mod - if so can you please tell me how you did it or even better if you have a picture

Well here is mine. It's a 1974 Ty250a that is a slow progress riding restoration job. The aim is to end up with a mildly tricked up bike but that still looks like an A model - I am almost certain to change my mind a few hundred times as the project goes on. I hope that by the time it's finished I am at least slightly competent on it as even though I have bene riding for 31 years I am amazingly rubbish at this trials lark :-) Anyway state of play as of today ....

Hi guys From what I can see many twin shock bikes came with tiller style yokes as standard and most modern bikes do not. It also seems quite popular to either mod or change the top yoke to get rid of the tiller system. So what was the original thinking behind them and what has changed now that makes them a bad idea ?

Thanks for all the input I decided on the dominos in the end after squeezing various kinds at the weekend and working out what my cables would fit into most easily.

Thanks B40rt Does the lever have a bush or does it run with the hole in the ally straight onto the lever pivot bolt ?

Thanks for all the replies. Quite a bit of support for the Dominos but leverage is something that I need to consider as the clutch routing on the twinshock TY250 isnt exactly ideal I am quite tempted by some on John Cane's TY site - I think they are made by Apico ( forged ) and have 3 positions on the lever for the nipple so you can adjust the ratio - has anyone tried these ?

Hi Guys Although I specifically want some new levers for my 1974 TY250 I thought it made more sense to ask in here as it is a more generic question What levers would you recommend ? I currently have some VERY nasty generic ones on the bike and need to change them asap Also do all the trials levers on the market accept the same size cable barrels ? Thanks in advance for any help

Thanks for the info and especially those very interesting photos Where are those photos from - a book or magazine ?

Hi guys I found this picture when searching in Google Can someone tell me anything about this bike please http://www.trialscentral.com/forums/gallery/image/1743-works-ty/

Thanks for the quick reply - washers it is then
