No idea.

I recommend the ones Brompton sells. They are self adjusting and have a ratchet to keep them set while the oil pressure is low. This means the cam timing can't slip and there is no annoying rattle at startup.

Why not ask the seller? Surely it comes with instructions?

I can help you mate......... stick it on ebay and buy one of mine.

I have seen an engine that had a manual tensioner fitted... the guy forget to adjust it after every ride and it foooked the top end when it jumped a tooth...it had to have a ÂŁ400 ish rebuild. :eek::eek:

Mine are fit and forget and supplied with full simple to understand fitting instructions. :cool::cool:

I believe you have to take a measurement to calculate the slack on the cam chain, If you get it wrong it can knacker the cams.

If I was you I would flog it again or put it down to experience and buy an automatic one from me.

Thats not a blatent request to buy mine, Its just my opinion on what I would do.

I don't like the idea of fooooking about trying to get the cam chain correctly tensioned when there is another tensioner that will do the job for you, Like I said thats just my opinion.

Sorry I cant help you with any advice how to correctly set yours up, I am sure if you percivere you will get it sorted.

thats not a very nice thing to say kev you would,t wish that on any one,this is what i was told,get the engine at TDC take off the rocker top,take out the ktm tensioner and replace with the manual one adjust up the tensioner untill you get 2 to 3 mm slack chain at the top between the cam gears lock up the tensioner and job done,sorry to say but it sounding and running good will let you know when it goes wrong,
