Spark right voltage regulator completely fried but looks good for a authentic looking rebuild. Military spec handlebars (slightly higher than the civvy police ones, good chr...

Re: ip2 Threaded insert on frame failed

You could use a helicoil but when you break the tang off the insert it would be advantageous to recover it rather than let it float about in the frame cavity.

Re: Re wiring an interpol .

The temperature gauge is separate from the retard system and takes it's signal from a sensor screwed in next to the spark plug (can't remember which side but it doesn't matter) the fag packet box is the retard box and is activated by the thermistor just above the RH inlet tube on the rotor housing (...

Re: Rear Brake IP2

You need to elevate the calliper to get the bleed nipple to the top when you bleed the system. Also the linkage from pedal to master cylinder is often bone dry. some grease here might improve things. Sintered pads may improve things but they tend to be hard on the disc wear wise.

All the popular detergents are thickened up by adding salt. Don't use fairy liquid and especially to lubricate your tyres when fitting them.

I have heard of opening up the two exit holes on the side fairings. There is a slight lip on them and removing this lip will give a bigger escape for the hot air.

Re: RAF interpol exhausts glowing red.

I suppose that if someone had left out the tubes from the rotor housing into the exhaust manifold then the pipes could easily get that hot. A few years ago I was passed at high speed by a members IP2 with reversed flow air and a trick scavenge exhaust. His complete exhaust system was bright red.

Re: Commander Handlebars

I would be wary of stainless steel bars. They are generally much thinner steel tubing and bend easily in a spill. Not up to the job IMHO. They are made from thinner stainless tube because thicker tubing would be too hard to bend without kinking.

Re: F1 Sport clutch judder

Can you describe the symptoms you are getting more precisely. The F1 is prone to a lot of transmission snatch at low speed and on a feathered throttle. This problem disappears as the pressure on the drive system is increased , i.e. with an opening throttle. Have you ridden the bike when the clutch d...

Cracked balance pipes seem to be the norm on these bikes. I cut mine off and got a local fabricator to patch the hole. it is easier to remove the silencer and manifold as one piece then beat it to death on the bench to get them apart.

Re: IP2 air bypass pipes

Latest theory, If the choke/enrichment O rings are shot then they may leak air allowing my tick over to creep up. I've re-tuned the air bleed screws but the tick over is slow to drop back to idle and then not reliable. You don't tend to think about the choke mech. Looking at an old SU from an Austin...

Re: Filling rotor chambers with oil laying up

If you are putting oil into the chambers via the spark plug hole, you need to turn the engine over backwards. The next stop for the oil when turning forwards is the exhaust pipe and the oil has only covered a third of the surface of the chamber.
