I twindisced a 500 back in 76 with one caliper in front and one behind as no 550 front ends were available and i used a GL 1000 master as i could get a Lucas pattern one ( cosmetic second from jal supplier) It worked perfectly but be carefull of big handfulls on very wet roads as you fall off! Got the tee shirt and video for that one

Stood that long it will need all the seals changed so a full strip down is on the cards therefore split the chain then remove the cam before trying to turn from the generator end NOT the points end after filling the bores via the plug holes with whichever brew you choose

Trigger, back in late 70's we had a man who subbed for Dowty and he would grind the cam bearings, bore out the towers and make split bronze bushes that were pegged to the towres and caps. This was when we had a standing order with Fowlers for a complete set of cam, towers and folowers which they could only supply every 2 or 3 months so more common to repair

Dont know what trigger would say but i rebuilt many with worse journals way back when and they were OK. By the way the cam does not have to be in a specific position to undo or tighten the sproket bolts, you can turn the engine between bolts but before you replace followers and pivots

You cant always swop the shrouds from one shock to another, depends on the retaining collars

Did you know you can measure to a 10 thou accuracy with a steel rule!




They have marks every 1/2mm and you can judge the centre of two marks easily and 1/4mm is 10 thou

From memory the F2 has a longer bolt as it goes through the two alloy footrest plates, try comparing part numbers on CMSNL
