Thanks Amar for the quick response.

So it is probable that your valves were in good order and did not need to be replaced.

I just don't know about my gearbox so. I don't have any obvious mechanical crashing etc, well apart from the severe thumping and hopping from gear to gear lower down the range. i've had all the electrical connections etc checked and they are all good. So i'm wondering if what Amar has had done would be sufficient for my situation at all as i "think" it is to do with wear off the valves or damaged valves.

Ben, you're prob most familiar with my situation - what do you think? Or if anyone else has thoughts on this i'd welcome the input.
