    Jato transmission issues???

    Hi guys I recently bought my son a 2nd hand jato with a seized engine. After a quick strip down it turned out to be full of solid congealed fuel. The truck generally looks in near new condition as the ally plate is unscratched. Now I got the truck running today after resetting the screws as they were miles out and truck wouldn't idle. Now it runs lovely, so all is good with the engine at least. As I went to drive the truck it pulled away fine but as soon as you hit the throttle hard it would stop driving and just rev. As the revs dropped down again the truck would give a little jolt (like is was going back into gear again) and would then drive fine again gently but hit the throttle hard and the same would happen again. Any ideas? Slipper clutch? Transmission knackered?

    sounds like the slipper clutch. tighten up the slipper clutch and see what it does.

    I would say it sounds like clutch bell, perhaps also the settings on the centrifugal clutch for the gearbox

    Typically that is a slipper issue. Try tightening the nut on the slipper clutch and see if the problem persists.

    Best thing to do is view what is spinning and what is not and you found your disconnect.

    Check the clutch pads located behind the clutch bell. Hopefully you can get some resolve.

    Thanks for your replies, have tightened up the slipper clutch a bit but didn't have time to test as had to get ready for work. Will try it out tomorrow. Fingers crossed.

    Well that didn't cure the issue. �� So the previous owner either fiddled with the shift point or its screwed. So might just buy a single speed conversion kit for it and have no problems with it then.
