Rear brake components bent?

Trying to find out why my IP2's back brake is pretty rubbish, I have stripped it down to find, surprisingly, the mountings on the rear torque arm are not parallel. Torque arm.jpg Torque arm bolts fail to align against the straight edges of a tool tray. The arm's mounting on the rear caliper bracket ...

Re: Air-cooled engine anti-ring rubbers

I think the 400 Richard referred to is the number of air-cooled engines fitted with the rubbers, ie, 300 IP2s and 100 Classics.

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.

Air-cooled engine anti-ring rubbers

Is there any guidance on what the correct fitting is of the anti-ring rubbers on air-cooled IP2/Classic engines? My IP2 is up on the bench and I can now clearly see three untidy rows of rubbers on the right rotor housing cooling fins, but none on the left hand housing. Both end plates look OK, with ...

Re: Classic rear shocks spring rate

Sorted! I found an online calculator. The Classic rear shock spring rate is 87lb/in, which fits in with other bikes around that size/weight etc.

Classic rear shocks spring rate

I need to replace the rear shocks on my IP2, which is now in a roadster style. As I can hardly compress the standard IP2 Girlings, which have a spring rate of 126lb/in, presumably to cope with the weight of all the police equipment (and big coppers), it seems sensible to fit shocks intended for the ...

Re: Fuses

I would wire in a separate fuse for the lights, at the very least. As for calculating the fuse amp sizes, assuming you know how many watts each item is rated at, you can calculate the amps by the formula: watts = amps x volts. So a 60 watt headlamp uses 5 amps (5 x 12 volts = 60). However, you may n...

I've used the Carbtune kit successfully on other bikes, so would assume it's also OK to use on the Norton. I know the rotar...

Re: more amps

According to physics, watts = amps × volts, and in my IP2 workshop manual the generator is rated at 220w. That should mean that 220 watts = just over 18 amps x 12 volts. I think for bike electrical power consumption you'd be better off calculating how much watts in total you are using as opposed to ...

John. The air-cooled temperature gauge is totally different from the system on the water cooled engine. On the air-cooled there are two wires that come out of the engine just above the spark plug.
