Re: Engine vibration at high RPM

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...

Re: spark plugs

I thought I read somewhere that if you have used 'normal' plugs in the rotary, changing back to the surface discharge types might cause problems? The normal plugs apparently leave carbon in the recessed area that would not be there with a surface discharge plug fitted, and this gets scraped off as t...

Yes, I have a similar issue with my right hand port, but I think mine might be aggravated by having removed the small cover a few times (it's held down by one of the transfer port bolts) to access the vacuum pipe etc. I would have thought all the other bolts fixing the transfer ports would have been...

Re: Fuse Block

I replaced mine on my IP2 as the original exposed ceramic fuses were a bit loose and they had no cover. As John says, the Vehicle Wiring Products fuse box is a straight swap with the advantage of modern blade fuses. At the same time, I wired my rectifier/voltage regulator (from the Commander/Yamaha ...

Thanks Richard, that's a good tip and worth pursuing. I cured the same problem with a Commando I had years ago by having the master cylinder rebored.

Steel brakes lines for air-cooled IP2/Classic

Has anyone fitted braided brake lines to their IP2 or Classic, and if so, where did you get the from? Having refurbished my IP2's brakes, they are still not as good as I think they should be, so I can only assume the original rubber hoses are now way past their sell-by date. They are 34 years old af...

My mistake. Just checked the invoice and the engine was removed but it was the gearbox that was rebuilt with various new parts.

I also initially looked on the Andover site but couldn't find one either, but yes, I did find it with Richard's part number - Andover say it's an 'o' ring link though I can't see why it should be, as our chains are in a oil bath. In the meantime I also found one on the RGM site too: https://www.rgmn...

The tip for compressing the gaiter back into itself worked a treat, and the remnants of the split link, and a bit of something else, were flushed out of the bellows on the top gaiter.

The riveted link is the best way though, considering what could happen. And yes, I do consider myself luck...

Wise words indeed from Richard about the split link.

Mick
Slightly off the subject, can I ask what clamps you are using on your exhausts please? The one just visible in the pic looks a bit more substantial than the standard U bolt, which I don't think gives a gas tight seal - unless I have a duff pair.

Cheers guys.
Yes it does have an MOT - that fault obviously not picked up by the tester!
I didn't think it should be like that and suspected something was amiss.
I'll source a new torque arm and pivot plate, but by all accounts the back brake on IP2s and Classics aren't brilliant anyway?

Re: Air-cooled engine anti-ring rubbers

I was trying to clean up the fins and levered the rubbers out - they came out easily. They are indeed all hard but I've tried to put them back in some form of neat pattern which is a nightmare as they have a mind of their own! But I won't worry too much about them now.
