They are definatly one of the more dificult ones to do specialy when the rubbers are past selby date. If replacing rubbers fit rvf rubbers on the vfr they have a tappered face to aid instalation.
Good advice here :)

Great success! I managed to do it in 10 minutes!

As you see, my exhaust needs new collars, does anyone have measurements for this?
Are the electrics by the fan and thermostat not meant to sit attached on a bracket?
Tips on radiator cleaning?

And it's all going fine. I start measuring the exhaust clearances, one is out of service limit, it's ok.

Then I wanted to do the inlets, but find out that the Draper so called "Valve clearance tool" doensn't have those intervals. But go up to .6, what do they expect you do to? Measure ferries?

Anyway, I'm in the market for a suitable valveclearance tool now :)

here is a decent feeler gauge. got the right increments for your valve clearances and a few bigger ones that could be of use for something else.

you can get good digital vernier calipers out there to measure the size of the shims for between £15 and £30

your collars are dead. if you can find someone down in Dublin to weld on stainless steel collars to fit then you can save a bundle. or just get yourself an aftermarket half system. fully stainless and add some extra performance to the bike :D

What system could that be? Already know someone who can weld it for me. But I need some measurements, I don't know how the collars are supposed to look like.

I was going to say before you got your carbs off was to warm the engine up before starting ,as this will soften the rubbers. I had a nightmere getting mine off the first time as I had to remove the thermostat and drain the fluid as the clamp screw was positioned right behind it ! Also use a small tourch to guide the screwdriver,

I just got a little heater we had in the house (with an inbuilt fan) and pointed it into the gap between the cylinder heads, waited an hour, and when I came back the carb rubbers were easy to deal with. Nice and soft :)

the collars need to be able to accept the front down pipes intothem without being loose and the need to be about 2 inches long - up to the stop/ridge on the front downpipe like in the first pic you put up.
Hope that helps?
I'm going to be doing the same to my spare system sometime in the future.
