Hi, just recently acquired a crm, thought it would be a brilliant bike to ride when 17, but the stupid thing keeps breaking down, one day it will start, the next it wont, ive had 3 different cdi's all known to be working, 2 reg rec's and still no fun. Had it running before, ran fan up the street then the next day not even a spark, any ideas guys as to what is up?

Hi Worksopcrm. Try stripping and cleaning the kill switch, and also check out the side stand switch. Both of them can be problematic. Good luck. Gwyn

Hi Gwyn, the side stand mod has already been carried out, and the kill switch was stripped down and tested yesterday.

Damo_crm? That was a quick name change
Coil, ht lead, plug cap? What havent you checked

Changed plug, coil, ht lead, had an electrical engineer trace every single wire.

Have you checked out the ignition switch? I had a Dr350 once, and i had to strip and clean the ignition switch quite often as the contacts would get dirty and full of crud. And if i sprayed WD40 down the ignition barrel it would make it even worse.

No, dad sparayed some wd down it yesterday the plank, but will strip it at work tomorrow. Thanks for the help and a post will be made after its been done.

I had a similar problem on a MK 2 recently and it does drive you nuts, great some days start every time next day no spark, there were two problems :

1 The kill switch had an intermittent break in one of the wires, found whilst
using a meter and wriggling/pulling wires. took it apart and resoldered
on the switch. Even rang LT and they said even if it looks ok and has
been tested it can still be faulty, try a spare if you can get hold of one

2. The pick up points on the flywheel were rusty, these were then rubbed
cleaned and it now starts like a good un every time

Just wondering what the electrical engineer said? im guessing he said its ok. i think the answer is in the previous posts, cant be anything else.but make sure it is a spark problem.they wont spark much on a kick and its easy to miss. im sure theres lots of info in previous posts

Oh i always spray wd down the ignition switch on my cars and bikes,never had a problem, am i a plank to seriously i hope you sort it soon. please tell me if im wrong but is there not an ignition module as well? the one behind the light,

Rightio, checked the kill switch, ran a current threw it whilst wriggling, no joy, had the flywheel off today and the pick up points are kinda rusty so going to give them a good clean up, gonna inspect the stator plate aswell, will keep updated as soon as above had been tried. Many Thanks
Damien

Keep pluggin away Damo Good luck mate Keep us informed how you get on

Tried it, nothing whatsoever. I think i might do an insurance jobbie lol, seems the only way to get my money back
God i wish i'd spent the money on building my peugeot to race spec
Thanks anyways guys, you've been a great help

Damien

stupid q but when you replaced the coil did you replace the lead and the cap??

or at least re-make the connections.

apparently reg rec fault can cause a fault with cdi coil and [power valve motor black thing with control cables]. worth alook/.
