November 1, 20169 yr Morning all. I finally finished putting the Sherpa back together today. It has started and run but is bogging down and not revving cleanly. Could this be the timing out?
November 1, 20169 yr Author Well I left it to make a coffee, re-started it, easily, then warmed it and had a run up the road. All seems well. Thanks to all for the invaluable advice. I'll be back.............
November 1, 20169 yr My best diagnosis from the video is that it just needed warming up to respond to the throttle properly, video shows typical lagging response when cold. Other than that, have you eliminated any slack from the throttle cable? Even allowing for the delayed response when cold, you seem to be rolling the twistgrip a long way before the revs rise.

November 2, 20169 yr Did you retime the engine when you put it all back together. If not then you will have to time it anyway. Especially if it is still on points. If so they like to be timed often. Graham.
November 2, 20169 yr Electronic ignition all the way on mine no messing about with the points and timing. Edited November 2, 20169 yr by bondy
November 2, 20169 yr Author I can't run to electronic ignition at the mo. I made a timing mark on the case and magneto using a punch and electronic vernier guage and re-timed it. I ran it again later yesterday and made sure it was warmed up properly. It runs well now. It started well several times and I'll give it another run on the toad tomorrow. I just need somewhere off road now to have a proper play Cheers. Neil
