There is a slight marking on one of the adjuster from grips being used instead of the c spanner. see ...

I guess from your title you want oversize pistons/rings. If not I have a complete set of standard rings that have only done 100 miles. I found that my bores were at maximum tollerance so needed a rebore. There's some used pistons which I was told by S.E.P were close to minimum tollerance so I replac...

Rotor was good but worth checking. It's all back together now. I checked the carb float levels and had one high one ( same cylinder as I had the tight shim). Also when I put the exhaust back on I tightened the headers first before putting the silencer on. This resulted in the rear mount being about ...

I've used POR15 in my tank and although it 's only been in there a year it hasn't peeled or cracked. Time will tell if it does fail but I didn't have much choice as I had rust deep in the lower seam with pinholes in a couple of places. I used the 3 stage system- Marine clean, Dry out the tank with a...

No I didn't notice anything when I had it apart. I haven't started it up yet so will take it apart again tomorrow to check.
Thanks for the tip.

Right here goes. I've started to do the service so exhaust off, checked all through and no broken welds, loose baffles etc. It is single skin so no problems there. Dumped the oil out and all was good. Nothing abnormal in the oil. Good sign so new oil and filter. Took off the alternator cover because...

All I have managed to do today is remove the rear exhaust mount and pull the exhaust away from the frame at this point and guess what.............. ITS STILL THERE!!! :evil: Now I'm not sure if it is the exhaust or not. I'm going to give it a service (shims, carbs, oil change etc etc ) and I think I...

Not 100% but think the downpipes are single skin but I understand where your coming from :wink: Will check it and check it again. If the exhaust doesn't shed any light then not sure where to go next.
But I live in hope

As I remember the baffle is a very tight fit and once removed its just a straight through pipe but I will look at the collector box when I've got it apart. Going to fit the centerstand bracket on the left now. I just prefered it on the right as it's mostly hidden behind the silencer but if it cures ...

Update. Chris, I have just warmed the bike up and it does vibrate at 4000 plus on tickover. This eliminates the drivechain I also pulled the clutch in and had no change. Then I touched various engine casings to see if there was a particular area but there wasn't any significant vibration from any of...

Looking good. Amazing how a good paint job transforms a bike. Well smart and looking back at what you started with, many people may have chucked the towel in. Well done !
