KIPS problem

[JanBros]

I was cleaning up my attick couple off weeks ago and found out I have lot's off engines taken appart (more than I thought I had). So thought I'd put some together just to find out what's good and what's not (like crancks and stuff like that, just to see if bearrings/seals are ok)

So today I finished setting up a rolling frame with everything needed to run an engine, and the first one is fine (allthough cylindres and pistons clearly have too much miles on them )

just one problem : the KIPS works when switching on the ignition switch, but it doesn't work when revving the bike. it's not the CDI, 'cause I tried 3 off which I know they( should) work .

anybody ever had this ? thought I might ask before I start looking for the problem - basicly I'm a lazy guy

Just a thought Jan does the rev counter give the signal to the ecu & have you got one fitted?

[JanBros]

no rev counter.

but it's not the rev counter that keeps the CDI informed. signal that goes to the rev counter is the same one that goes to the coil

today, I had the same problem with my new rebuild engine. So problem laid outside the engine.

after swapping stator/coil/CDI, problem still excisted. So I fitted a rev-counter to see ecxactly how high the engine revved, and wouldn't go above 8.000. But I also noticed the rev counter kept indicating about 3-4000 rpm's when it was clearly only running about 12-1500 rpm.

So I changed the loom (only part not swapped), and problem was cured

Kind of strange problem, since the engine appears to run perfectly up until +/- 8.000. When I have the time (probably something for the next decade ), I'll strip it completly and have a look to see if I can find something

im interest in a crank a good one if you got one going for sale, just when my current project is finished i have an engine that needs one, going to rebuild for a spare tuck it away for a rainy day cheers wayne.
