Hi, hope someone can tell me exactly what I have gone and bought. Here goes: Frame Number CJ01C-011463 Engine number H303E-006569 Carb type Keihin FL AT CR marked 5BEI-00ME12 I bought this fairly cheap described as a 2003/4 YZ426. It ran great and was in good condition so didn't question anything as I was going to put it on the road. It has a speedo drive on the front wheel and there is evidence of a yellow wire coming out of the stator, although there is no lighting coil anymore. It has a decomp lever, but no hot start button. On the carb there is a bunch of wiring and a mechanism above the choke lever that looks like it may be a hot start device of some sort. There are a bunch of wires heading into the crankcase by the gear selector. None of the above adds up and I can not find anything similar on the web. Its very hard to start full stop, and with no apparent hot start button. Can anyone help ? I'm in the UK by the way.
