Re: For Sale Supreme Commander

Thanks Clive/Richard. Very tasty and I should think the other changes under the bodywork that can't be seen can surprise quite a few modern bikes on the road.

Re: For Sale Supreme Commander

Anyone got any pictures of these rare Supreme Commanders?
I tried googling it but all I got was Ed Straker's car from 70's TV series UFO!

Re: Ex-Police Commander

Something not quite right with this one being billed as ex-police? No reflective tape anywhere for a start.
Might be another TRRL bike - look at those huge leg guards on the fairing. Can't ever remember seeing those on any production Commander?

Re: IP2/Classic front wheel

What a doddle - it came straight off in less than 10 seconds!
After something like 35 years on the front wheel exposed to who knows what, I was expecting it to be a real struggle. In my view a real testament to the build quality of the rotaries by Richard and colleagues at Shenstone.

IP2/Classic front wheel

Does anyone know how to remove the speedo drive off the front wheel on the Grimeca alloys fitted to the IP2 and Classic? The workshop manual simply says "Extract the speedometer drive gear" without explaining how to actually extract it. I have cleaned all the grease off that area to have a closer lo...

Re: Commander rear brake disc

Does the rear disc get that hot on the Commander? I've only got the naked IP2 where the rear wheel is completely open, so if it sounds like a daft question my apologies. For John's benefit, here is a vented disc next to a standard solid disc - these are car disc brakes though, the Yamaha ones are mu...

Re: Charging issue - high revs equal low volts??

I have now wired the digital voltmeter direct to the battery, with fuse, and taken the bike out for a run. At tickover it first shows 13.4 volts and quickly rises to 14.7 volts, and then stays between 14.4-14.8 volts riding along with no load. Side lights drops it down to 13.8 volts and with the hea...

I agree Clive. I was going to do a full rewire over this next winter anyway even before I saw how bad the harness was, but looks like I will need to do something sooner. Regarding the warning light, I added it before the voltmeter, as the XJ/Commander reg/rectifier on my IP2 does not have any warnin...

Re: Charging issue - high revs equal low volts??

This is proving to be tricky. The charging system appears to be working at the battery end, which is probably the most important bit, but the warning light and digital voltmeter within the wiring loom say otherwise, which isn't too bad but annoying as they should really tally with the battery and de...

Re: Charging issue - high revs equal low volts??

I think I might have solved it - or at least know where to look next. I checked for earth continuity between the rectifier and battery -ve and it's fine, but to reinforce it I have added a separate lead. The same readings are showing as before. Then I thought it worth double checking what was actual...

Having finally resolved my fuel leak after rebuilding the carbs once, but the petrol tap six times and then reverting back to its original diaphragm, I now have a bizarre charging problem in that as revs rise the volts drop off.

IP2 front wheel buckled?

Whilst my IP2 is up on the ramp, I checked the front wheel as I recall the last time I looked at it back in the winter I thought it was not quite true, but then forgot all about it. Sure enough, spinning it round shows about 2mm difference on the side and about 1mm vertical. I assume as mine is an e...

Good news on that Mick. I took my right transfer port off to re-seal it and I've done around 100 miles or so. However, the bike's up on the bench again as I have to take the carbs off to replace leaking float chamber valves. And I have to remove that bolt that holds the engine cover in place, but gu...
