Re: Classic engine back in

IP2 and Classic tyre sizes

New tyres are needed for my IP2 but I am confused over sizes, as there seem to be quite a few different combinations posted in various road tests, the workshop manual, etc. They are all V18: 100/80; 100/90; and 110/80 for the front tyre. And for the rear: 110/90; 120/80; and 120/90. I have seen all ...

New chain gaiters

Following the mentions of the new gaiters (in both the latest Epitrochoid and Roadholder) that Chris H has produced, my order for a set is ready to be placed. However, the email address provided by Tim in Roadholder does not appear to work, so Chris, any chance you can post a reply on here please an...

Forum problem regarding bogus topics

We seem to be being increasingly targeted by scammers on the forum. Is there anything the tech team can do to purge it please, or perhaps shut down the forum briefly to put them off? I have stopped looking at anything on the forum at the moment as there is clearly something going on that is not righ...

Bogus postings or scamming?

We seem to be being targeted by some bizarre postings in the last few days. Are these mistakes, pranks or something more sinister?
I am not going to open any of them in case they contain a virus. The Guzzi owners club was the target of the latter earlier this year.

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.

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.

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...

I think I might have solved it - or at least know where to look next.

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...

I've got the IP2 which is air cooled but has the same carbs as your Commander and also had poor running problems. Regarding the mixture, I'm pretty sure you should be doing this by taking the carb tops off and setting the jet height to an exact measurement as explained in the workshop manual. As I u...
