Just got back to KL after a work trip around the world and went to start the bikes, so I can give them both a run and blow the cobwebs off.
The VFR750 starts first time no problems at all, just as always.
The VN750, will not start, keep cranking, still will not start. have petrol smell from the exhaust so fuel seems ok. Took out a plug, a bit damp from fuel tried to start, no spark. Tried to start again, biggest backfire I have heard in a long time, sounded life a rifle going off, woke up the neighbours nicely.
Just had new coils fitted to try and improve the hot starting, checked the coils, all ok. Thought I'd better check the ignitor, after the fight to get the bottom bolt out and to find the Fluke meter I get around to the test. A good number of the results are totally out of spec. Tested the ignition coils and the pulse coils and they are all within spec.
Got to suspect the ignitor, now try to get a replacement, my local shop - $420.00 new, bit over the top so hunt Ebay a find a secondhand one for $40 + postage. Waiting for it to arrive, and hopefully it fixes the problem. I'll let you all know when it gets here.
I have attached a spreadsheet (in a zip file as I could not attach the Excel spreadsheet) I put together to make the recording of the Ignitor tests easy, it also has my test results as well for reference.
Now it gives me a chance to clean the VN750 while it is all apart. More work, and the VFR sits there saying ride me, ride me which is very tempting.
Have a good weekend.
