MOT now passed with just a couple of minor advisories, time to put some miles on it.

Well I've finally got the bike up and running on all 4 cylinders. I decided to bypass the air cut valves and after another thorough clean of the carbs and a re synch it's sounding pretty good. The starter clutch has all been repaired and everything is now completed barring a few bulbs required...

I also found a lot of crud in the carb bowls when I drained them, wondering if this could be the source?? I pulled the bowls to check for more crud and there was a small amount. Whilst the bowl is off any chance of confirming if I have the correct jet orientation? I'm now considering bypassing...

So carbs are pulled and air cut no1 inspected. The plunger was seized in the carb body and as can be seen a lot of corrosion but the rubber seemed fine.

Yeah I've also used Loctite so hopefully it shouldn't move :thumbsup:

I have used liquid metal, used it for many other applications with good success so far.

Just a quick update on this, I needed to sort out the starter clutch rattle so I removed the advance assembly and found that the pin holding it was damaged and had also chewed on the assembly. The starter bolts have now been cleaned and loctited and the e metal is curing on the assembly ready...

Fixed with a few hours of filing and grinding paste.

Also does anyone have a picture or link to the locating dowel for the mechanical advance unit? Mine appears to be a filed square nail to fit in the crank and I'm thinking that this may have caused some damage to the crank splines that I hope I can dress out. It has certainly started to chew the...

Does anyone have difficulty removing theirs from the crank? Bike is 1979 DOHC. I needed a pullers to get mine off, splines looked to be OK though.

Thanks I'll look into that. The carbs were not immersed in cleaner but they did have a lot of spraying into most orifices, I didn't remove the air cut covers however. I think another stripdown is on the cards though :thumbsup:

Woops just duplicated my post.

:Woops just duplicated my post.

Thanks for all the helpful info, looks like I'll be pulling the carbs again then, I only shot a load of carb cleaner through the idle fuel jet, didn't actually probe it. I think I read somewhere (probably on here) that you can bypass the air cuts by tweaking open the pilot mixture screws is that...

I did have a few issues with the carbs. On no 4 cylinder the air slider was stuck and not returning under spring pressure. 2 of the pilot air screws had snapped their ends off in the carbs and all 4 rubber bungs over the idle jet (hope I'm right there) were hard and split so I had new aluminium...
