Anyone built Akront alloy rims from the seventies with Stainless spokes?

Hoping someone can help me on this? My fantic has developed a problem! It will start ok, run then die like the kill button is pressed, some times it will run for a few seconds other times a few minutes Disconnected kill switch completely Check earth and all connections, good Cleaned carb with airline all good, Stator was rewound after the new year Spark is good, Replaced plug, cap and HT lead Top coil is 12 month old dans tyoe, Fault started after a couple of sections of trial, it was running great 5 weeks earlier on the last outing.

Hello, Hope someone can help me out with a tech problem, I have a 1978 TY250 which starts from cold ok the bike will run for 30 seconds or so then starts to die as if petrol not getting through then stops and wont restart for an hour or two when the pattern is repeated. I have a good spark, petrol is getting into the carb, i have cleaned the carb and blown out all the jets, Any ideas ? Cheers, Frankie,

Need a bit of help to get my head around steering mods on a twinshock. I've read about people fitting parallel yokes to alter the steering angle, rather than cutting and re welding frames. Does that not just shorten the wheel base and leave the fork angle the same? Just wondering whats needed to improve steering is it about the rake on the forks or the wheel base? Cheers.

I scored a BSA Victor with a B250 motor and figured I would build a trials bike out of it. I brought the head angle in, brought down the upper shock mounts etc. i am up to the point to set steering stops. My forks (old betor) have 70mm offset and my tank is really narrow. Would 90* be a good point to set stops? I can make thicker bumpers later. thanks. Frank

Hi - I have finally fitted a new tank/seat to my 76 Cota 247 and I have a new set of badges (soft sort of plastic) ready to apply. The tank is new and so very shiny and woudld hate for the badges to fall off somewhere in the paddock so rather than resorting to my trustee cyanoacrylate (superglue) I thought I better ask advice eg: should I roughen the nice new shiny surface where the badges are fitted? And what glue is going to work best with a fibreglass fuel tank?

I have bought a stop switch for my bike and want to make sure im wiring it correctly. The switch is open circuit until pressed. Do i need to put one of th wires from the switch to a earth point so when depressed it shorts the wire from the coil to earth and therefore stopping the engine. Cheers Mark

How do you remove the small allen bolt at the bottom of the fork legs (ie stop it revolving inside?) as i want to strip my forks on my suzuki? thanks in advance!

I'm working on a 74 Sherpa T that I recently purchased. The bike was in storage for over 10 years and was reported to be "in running order" when it was put away. But after tearing in to the motor I found she is stuck solid. The broken kick start shaft probably should have been a clue So now I need suggestions on how to get it apart to do a proper job of getting her back in order. Any suggestions would be greatly appreciated.

Hello... I have just bought a cota 348... first trials bike in 20 plus years.. How is the suspention on a trials bike set up ?

I noticed excessive movement in the swing arm on my Cota 247 and I find that the pivot mounting holes on the frame itself have worn and are allowing the movement. Can anyone suggest an easy fix and failing that give me the hard fix options.
