Could I suggest something I do,

Take the bike for a run   about 15 to 20 miles  get it nice and warm
When home, keep the engine running, put on centre stand

Get your long screw driver

Now ,turn one airscrew a quarter turn out,
Check what happens, blip the throttle, OK?

If it struggles,turn to previous settings

But if its OK,do another, repeat, and check

Remember, Modern fuel is different than 50years ago,

It might like a leaner tickover

Can I suggest when you fit the replacement, make sure you don't over tighten it,

I have a thought, the joints and the  splines on the shaft drive,

I know a friend that had a K brick had issues

Back in the 80s

I also used Champion A8Y


Definitely a  projecting nose plug,

The bike ran well, but they became difficult to get

Check for the washer between the spring and the oil filter. Often stuck to the oil filter and often accidentally binned. I have 3 engines here and none of them had the washer.

BTW mine are 400s, I imagine yours has a similar washer.
Yes, the 500 has them
Fit between filter and spring

Good for you,

The idea of the small head, is to stop it being tightened to much,

I also grease the O ring under the head to prevent it sticking/corroding

Actually, I run Denso x24ea-u

I believe that the are equivalent to  the D 8ea

A d7ea is normal for the 500

The 8s are for 400,750 etc

I dispute this,

My 500 has no issue

In fact, I use a harder plug than reccomended, an 8 instead of a 7 ,

I have checked the tickover mixture, and my airscrews are turned out more than normal,

I also have Boyer ignition, and run the plug gaps at 33thou,

Im planning to lift the 550 engine out of the frame at the weekend and intended to take off the Oil Filter housing to make removal from the frame easier. The bolt on the oil filter housing looks horrendous, no flats left and I doubt a smaller socket tapped onto it would grip. I can probably get my large Molegrips on it but before I go down that route are there any tips for tackling this? I have given it a good squirt of WD and left it to soak in. Thanks
What a beaut!

Good luck

The system on the sohc is very simple,

David Silver does a complete replacement master cylinder for less than £40 I seem to remember,

The caliper will possibly need a new seal,also check, and if corroded replace the caliper piston,

Also check the hoses for cracks and splits,

That covers the hydraulic section,

The only other thing is make sure the alloy arm that the caliper mounts on ,the swivel is free for it to move,
