Re: Sidestand length and excessive lean
My sidestand was getting to the point where the bike leant over so far it was difficult to get the bike back to upright. It seems modest movement at the top end translates into a big movement at the bottom end. I have improved mine a bit a one benefit is that the bike fills better with petrol whilst...

Re: What a Din, engine sounds dreadful
I had a similar problem, I had a recon engine in the cupboard under the stairs which I have put in, with JB assisting. The noise is gone so definitely the engine. I suspected a bearing and if it was it could have broken up and wrecked the engine. I even bought a stethoscope but couldn't locate the e...

Re: Going to a rally
I usually get around 800 km per litre when two up and fully loaded. Two lites with you should be sufficient. When doing a similar journey I realised in France that I wasn't going to make it so topped up early with a litre of 30 SAE lawnmower oil with no ill effect.

Hi Trevor, given all the work that you have been undertaking I assumed that you had a workshop manual but if not they are available for the Commander at Andover Norton.

Re: What make are commander front forks
Hi Trevor. My Commander goes onto the centre stand easily and lifts the back wheel off the ground. If the bike rides well the forks are probably OK and need to settle. After a rebuild I vigorously press the forks up and down to get the hydraulics working properly. Others may have more information bu...

Hi Trevor, the forks are Yamaha late '80s XJ900 fitted as standard to the Commander. Likewise the wheels and brakes. If you have anything different they are non standard.

Hi Trevor, further to my previous reply, the four pot Billet calipers are listed on the Harrison Billet website. They are designed fit the XJ900 forks without the need for new discs or fork modification. They probably sell pads but I use 880 Ducati items.

Re: Classic starter problem
The sprag has to be matched with the drive gear and engine sprocket. It is generally recommended that the three are installed together as new parts.

Re: Classic starter problem
Is it the starter sprag clutch. If it is not gripping the sprocket the starter will spin but won't turn the engine. This is a common problem on the Mk3 Commando but the freer spinning rotary with no backfire does not wear them out so quickly.

Re: giving way on roundabouts
Hi JB. When I passed my motorcycle test in 1964 the Highway Code stated that there was, unless stated, no designated right of way on roundabouts. This was often inaccurately taken to mean that the right of way was with the main road. I think that the give way to the right came in around 1966/7.

It would ...
