I find the Roadriders are one of the best tyres I've tried, certainly in terms of grip (probably not wear though). I don't like Pirellis either, ever since I wrote off a TR4 round a bend when the rear tyres lost grip.... I've got them on my Thruxton, but when they're worn I'll change them for Roadriders or Roadrunners.

Yep, I'm sure Avon have a recommendation but I've found with Avons on other bikes that it takes a bit of experimentation to get things just right. However, it sounds as if your problem might not be pressure. On the other hand, if something isn't loose and you still have a problem, give it a go?

the clunk on tyre skipping could just be suspension end of travel as the tyre skips out?

The EFI seems to have a habit of wearing out the swinging arm bushes. Mr H has an upgrade.

Mark M, thanks, I have played around with tyre pressure. Originally at RE handbook 18/28, which is how I discovered the front RE is way out. Back end has adjustable shocks too. I've had the rear anywhere from 28psi to 36psi two-up, doesn't seem to make much difference. Bicycle track pump and digital pressure gauge make short work of adjusting. I need to check the swinging arm for play now, I have felt a clunk as the bike shifts, and adjust as required.

If you can feel and hear a "clunk" I'd guess there's something pretty badly worn. I've not noticed any bad habits from my Electra EFI, handles as sweet as always, but cleaning it the other day I found I was moving the rear wheel sideways just with the polishing cloth. New swingarm bushes ordered! Might be worth checking rear wheel bearings too while you're at it?

I was thinking about the "clunk". It is also possible the rear wheel spindle is loose on one side. Because it's a q/d design it is possible to have one side (usually the sprocket side) fully tightened and the other a little loose, allowing the spindle and snail cam on that side to rock back and forth under braking and acceleration. The resulting noise can be quite loud and you can definitely feel something is amiss at the rear end. You'll have guessed how I know...

I've had this, ordered new bushes but when going to change them I noticed nut on one side was not very tight - I thought tightening either end would suffice, but somehow not. Anyway, did it up and problem cured without needing the bushes.

You have "felt a clunk as the bike shifts" and not immediately investigated .....???

Id be tempted to have a look at the shocks, if the tail is skipping out and the tyres arent that old it could be that its something other than rubber. Get the bike on the mainstand and give the back a decent heave arund to see if anything is loose.
