ajock Posted September 21, 2015 Report Share Posted September 21, 2015 Does anyone know where i can get a straight 40t rear sprocket, have 41t dished one but it brings the chain to close the shock. I have also seen sammy miller have 39t any advice? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
feetupfun Posted September 21, 2015 Report Share Posted September 21, 2015 The chain is supposed to be very close to the shock spring. If you move the sprocket teeth towards the centre of the bike, the chain will then be misaligned. Most people space the shock out a little at the bottom mount with a washer to give more chain clearance. The problem comes about because modern shocks have bigger diameter springs than what the bike was designed for 4 Quote Link to comment Share on other sites More sharing options...
jon v8 Posted September 22, 2015 Report Share Posted September 22, 2015 Feetup fun is spot on, most shock springs are too wide for the original Yamaha design.My old rat 250 chain rubs the spring,but I just turn the spring around so it misses. Never caused any problems though. If you do want to do something different Talon Engineering will make whatever you want within reason,they are really helpful people to deal with and one off sprockets dont cost much more than stock ones from them. 1 Quote Link to comment Share on other sites More sharing options...

old trials fanatic Posted September 23, 2015 Report Share Posted September 23, 2015 Thats the point though Jon i have an account at Talon they make sprockets for Villiers but they cant sell me one. I can buy sprockets for any other bike from them but Villiers services have stopped them selling them direct even to account holders. Grrr. I used to get them from Simon Bateman but now he's sold up to Villiers services i cant which is a shame as i really liked dealing with Simon who is a top bloke. Thanks for the contact above will give them a try. Sorry for hijacking the thread Quote Link to comment Share on other sites More sharing options...
jon v8 Posted September 23, 2015 Report Share Posted September 23, 2015 Yep, have a word with Paul, he is really helpful,a true enthusiast.We often ride together at Golden Valley trials etc. The situation with Villiers Services was discussed last weekend at the GV British bike trial, it seems you are not alone in your observations.
