The 500 lever is very slightly longer than the 550 lever but they look identical, it's very easy to mix the 2 up. The 550 has a letter A stamped on the inside of that block, the 500 doesn't.

Not sure what the PO fitted I'll check the shifter.
Pretty sure I can make an interlock to keep the choke off without too much difficulty.
There is always a cable tie if all else fails.lol

I'll check what lever I have first thanks Bryan - at least I've found the cause it was weird as the bike ran rougher and rougher so quickly. Glad it's something simple to sort out.

I have the same problem with my boots putting the choke on also but after realising what was happening it doesn’t seem to happen so much now so maybe I’ve adjusted my position slightly I also had an issue with my feet being too big I’ve got a 550k3 which isn’t a problem but my 550f2 I couldn’t change gear without catching the casing with my boots the k3 lever bends outward more than the f2 so I’ve fitted a k3 lever on the f2 problem solved my feet are size 10 so not abnormal

Finally went out on the 500 this morning without any drama - choke lever fixed in the OFF position with a narrow cable tie for now.
All five gears were good - I did quite a bit of accelerating & gentle braking to get the front pads settled - brakes got better with every application as the pads warmed up a little. Most importantly my hips were fine - it felt an easier ride than the 400 with the extra torque as you would expect.
A 10 mile road trip revealed a few things to look at during the re-build - an odd clonk from the front suspension area - plenty of general clatter from the engine but nothing too sinister sounding.
I'm thinking cam chain & primary drive chain & clutch area noises to my semi-trained ears plus a noisy exhuast blow near the silencer joint area.
Not that there was really ever any doubt - the engine will need stripping down it will be a few months before I start in earnest as I want to finish my 400 spare carb rebuild and put a few more miles on my 400 before the cold & rain sets in. I'll do a compression test beforehand to get a datum point. The engine pulls very well despite the above only wound her up to 60 mph briefly to feel the burn. lol

Only one nut holding it on - the other was loose!
I've started the frame strip already so engine might be out within a week or so.
