Title: Engine revs hard on right turns.
Post by: Olclops on August 10, 2015, 06:06:32 PM

Hi guys,

So I think I've found one of the issues behind the low power on my BS-7 ... the engine revs hard on right turns, and idles way low on left turns. Not sure how I missed that before.

I'm assuming the throttle cable is routed incorrectly, but I can't find a diagram of the right way to do it in the manual I pulled off here. Any tips?

Thanks!

Hi,,

As the idle is affected when you turn the steering, I assume it's the bit between the throttle grip and the splitter box that needs re-routing. On my bike, I've fitted the cable so that it the splitter box sits on the top frame tube, and the front cable emerges from between tank and frame tube on the left hand side. of the steering head. Then route the cable in  a long, easy sweep from beneath the headlamp shell into the throttle grip assembly. The cable should leave the throttle assembly pointing forwards and inwards at about 45 degrees. Set the throttle play adjuster so that you have at least 1mm of free play with the throttle closed at both extremes of steering movement.

The problem usually comes if someone has fitted higher handlebars than standard without changing the throttle cable.

Hope that makes sense.

Graham

Exactly what I needed, thank you, Graham!
