Re: Popham 2019

Popham turned out nice and sunny as forecasted but had my doubts on the way along the A272 with a fair bit of rain and wind in some stretches. Best part of a decade since I went any distance that way. Rather a sharp reminder of just how long it used to take to get anywhere in pre motorway days unles...

Re: Popham 2019

Hopefully I'll make it down too as Sunday is now free. Should have arranged an exhibitors ticket I guess.

Re: Commander Hot rear brake

The big advantage of DOT 5 silicon brake fluid is said to be that it is not hydroscopic so it doesn't absorb water. Because of this it is claimed to be ideal for vehicles that are rarely used because the properties won't change in storage. Allegedly it doesn't degrade at all so can last "forever". A...

Re: Commander Hot rear brake

I presume the pedal is returning fully and all the link pushrod adjustments are set correctly. Both my Commanders have liked a bit of slack in the system. When you pulled the pistons out did you look for corrosion / deposits in the seal grooves. Pretty much anything in there will make the pistons ti...

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

If you have some doubts as to the quality of the original loom probably the best fix would be to make a complete new set of wiring for the charging and metering system running direct to the battery. Dunno how your warning light works but if its anything other than a simple equipotential system I'd l...

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

Had similar issues with my second Commander. But not as bad. First fix was a new section of wiring loom running direct from the alternator to th regulator and then to the battery. Which seemed to work for a while. Next try was an aftermarket "improved" regulator which made less than no difference. I...

Re: Engine vibration at high RPM

Didn't know we could attach pictures. How is it done? Probably easier to PM me with your E-Mail and I'll send the only useful one I have direct. (Front of my first Commander looking every inch of 80,000 miles scruffy in late winter.) Actually as mine wears MZ 1000S forks and wheels as part of Richar...

Re: Engine vibration at high RPM

When mounting the FJ calipers I elected to retain the standard bottom mounting bolt position and swing the top back to get the pads contacting the right part of the disk. The FJ calipers are longer than the standard ones so the top mounting needs to be higher than the original fork leg boss as well ...

Re: Engine vibration at high RPM

Messing around with carb mixture settings by ear is never a good idea with multiple constant depression carburettors. You end up chasing one error with another so its pretty much impossible to hit a reliable setting that works over a range of conditions. Finding todays sweet spot is possible but goo...

Re: Gearbox oil

Thanks John Impressive looking website and list of products. Prices actually seem very reasonable for such (inevitably) limited production. However my reasonable might not be yours given where I used to work. Interpolating from prices on the site I'm guessing probable range of £3,000 - £3,500 includ...

Re: Gearbox oil

Redesigned gears sounds interesting but probably lots more than 2 grand now! Wonder how they would deal with main shaft deflection which is the root cause of problems. Objectively its just too long and too thin for the loads involved. I live in Sussex so its almost tempting to look them up if they a...

Re: Gearbox oil

I used R40. Probably best to put it on a regular 6,000 mile / once a year change schedule unless yours lives in a Bugatti standard heated motor house. Back in those days mine were on regular commuting runs so new oil went in regularly. 25 miles each way. Usually doing 25,000 + a year with all the ot...

Re: Gearbox oil

The Oerlikon Balzers treatment is a coating, not hardening. Can't say I really understand how it works but apparently that sort of thing is almost routine now for motorsport. Back then they were just getting serious about offering such services on a one off basis. Previously it was more industrial, ...

Re: Gearbox oil

Both mine did pretty well on Castrol R. Not something folk normally consider as gear oil but castor based lubricants do have one of the highest pressure capabilities of any simple oil. Main issues are thermal as it goes off when it gets too hot, and environmental as it needs a pretty well sealed gea...
