Honda Dio AF27
Current mods
1500 rpm koso clutch springs (contra and small)
New oem type belt
Lightened rollers, (2x 8g, 4x 4g)
(I have option for 6x6.5g, 6x8g, 6x4g)
V8 pipe, (bigger diameter than stock, for 70-90cc usually)
Upjetted, current 82 jet (stock 75), have a range from 75 to 100
Relevant replacements
Throttle cable
Problems
once the I kickstart the engine, it’s fine, but once I take the scooter off the stand, and stop the back wheel, the engine dies. When I try kickstart on the ground it launches it forwards, rear wheel doesn’t move. If I push the moped fast enough, with the ignition on, it will start the engine. Once I push start it, I can drive it around, but once I come to a stop, the issue repeats. I feel could be a clutch issue but not sure as I haven’t done anything to the clutch apart from replace the springs, and once i did that, this issue wasn’t happening.
Older issues, Throttle stays on even when cable is fully recessed, revs right up to full throttle unless I brake. Confident this is because I have to keep the idle screw all the way in to start it then it goes, once I screw idle out, it no longer happens from memory.
IMPORTANT: Shuts off occasionally if I come to a stop, or when I go up a hill then let off the throttle on a slight flat
on downhill, engine doesn’t idle can’t hear it when let off throttle until I pull throttle then it will bog then accelerate
Weird boggy noises throughout it running
When it dies, I try kickstarting it 30 times and have to wait a minute or two before I can start it again, (now I can’t kickstart it as per the push starting issue)
(These are probably all connected issues, they have been happening since I put the bigger exhaust on, I took the new exhaust for a run and the moped died at every set of lights and I couldn’t kick start it for ages.)
Any help is appreciated.
