throttle cable

Hi Sammy

The adjusters are on the carb throttle cable arm. Adjust as per the Owners Manual - available as a free download here

PS Not sure what you mean about the sprag clutch as its lubricated by the engine oil in the sump

First of all, determine which cable is the adjuster ; this will be the cable with the longest thread. This adjusting cable goes to the top mounting bracket. The other cable (obviously) goes in the lower mounting bracket.

First fit cables, then tighten the lower cable. This is NOT an adjuster and just needs to be tight.

Next, tighten the top adjusting cable until you have 2-5mm play at the throttle grip. To check this twist the throttle back-and-forth to check the free play. As long as there is a bit there, but not too much it will be fine. If you find that you do not have enough adjustment, use the adjuster on the handlebar's to compensate this.

If you have too much slack, it can get sticky, same as if you over-tighten it.

Once the correct adjustment is found, leave your bike idle, while turning the handlebars side; check that the idle does not raise or lower when doing this.

Very easy job.

Good luck

I've had a crack and think I sorted it, poor thing really needs a clean but she's my little work horse through winter.

thanks for advice

when it's low on oil it tends to Banff more frequent added oil and seems happier
