Where did you order your valve from?

Thanks for the pictures. On mine the protruding part of the pipe was less than half of that and had no angle on the end.

The good news is that I've managed to get it out without drilling it. A combination of heat, cold and a good twisting with a screw extractor and eventually out it came. Before that the ball bearing popped out together with what looked like a combination of a spring and silicon.

Anyway, I've ordered a new one. In the meantime I will get on with some other bits and pieces including giving the engine a good clean and polish while I've got it on the bench.

One other decision that I've got to make is what to do with the wheels. The chrome on them has some rusting and the spokes are pretty shabby. Any recommendations welcome.

Thanks for all of your help.

Cheers
Phil

When I got the bike there was no gauze filter in the sump and the end of the pipe was damaged. It had some of the end missing and what was left had a split in it. I fitted a mesh and new gaskets. However, as i said now that I've got the engine on the bench I can see that the ball bearing doesn't move and it looks like a piece of the spring has got past it.

There was never enough pipe to get hold of to pull it out and my attempts the remove it have certainly added to the damage and the end of the pipe where it was split has broken off. So it definitely has to be replaced now :(

Following your earlier reply I checked the other non-return valve and it appeared to be ok.

I think that the presence of the thread on the inside of the valve means that someone has either had this out or attempted to get it out in the past.

I've wrestled the engine out of the bike in order to fix an oil leak on the inner timing cover and to get a good look at the scavenge valve. I can now see that the valve is stuck in the open position and it looks like someone has tried to remove it in the past. It has a thread in it but most of the end that would sit it the sump is chewed up.

I've tried fitting a bolt, heating it up and pulling it out with a slide hammer, all without getting it to budge. So it now looks like I'll have to drill it out and obviously don't want to damage anything but I don't know how long it is or how the spring and ball bearing is held in place. Has anyone got any decent pictures of one or any experience of drilling or cutting one out?

Cheers

I contacted Boyer about it and they said the pick up would be from the black wire out of the ignition box. I tried it this afternoon but unfortunately it didn't work. Possibly just a duff tacho.
 
I must admit that I didn't expect much for 7 delivered from China but it was worth a try. I might have another fiddle with it later in the week.

Thanks for your help.

Just looking at this again. Which wire is the pulse output wire?
There are two, Black/White and Black /Yellow. I think it's the same on the Wassell system.

I came across this post because I'm having exactly the same problem with my 1970 Starfire. What size jet did you fit?

That would be a shame if it is.

The bike hadn't been run for a 2 -3 years prior to me buying it at the end of October. Since then I've been sorting out a few minor things so it has only been started a few times. I'll have to see how it goes when I give it a longer run.

It's been 2 - 3 weeks since I ran it and today when i took the sump cover off (because there's a leak) about half a pint came out.

Also, when I did have it running it was OK at idle but smokey when revved. Hoping this is just because of oil in the sump.

Thanks for responding.

The engine is still in the bike so I'll have to have a think about how I might heat that bit up.

Hi,
My Starfire has a lot of il in the sump. looking at the scavenge valve it's difficult to see if it's working ok. The end of it looks a bit chewed up so i would like to get it out and inspect it and if necessary replace it but how do you get it out? Iv'e seen reference to a grub screw but can't see one.

Has anyone done this?

Cheers
Phil

Well it came very  quickly  and matches the after market speedo that's on my bike already.
I tried setting it up but with no luck so far. I found a set of instructions on the net which shows the contact signal wire connected to the positive side of the coil but this doesn't seem correct  because that side of the coil on my bike connects to ground (+ve) .
I also  tried  the -ve  side of the coil but that didn't work  either.
The bike has Boyer ignition but didn't think that should make any  difference.

The earlier reply mentioned wrapping it round the ht lead. Won't that  deliver too much voltage?

Cheers
Phil

Yes would have thought that.

Also, If you look at that part of the engine in the picture there's a seam just above where the port would  be.  I'm not sure if this is a normal part of the casting or indicates that there's been  a repair.  Not been able to look up close at another one to tell.

I suppose it's part of the fun of owning an old bike. I'm certainly enjoying it so.  Plenty to fiddle with but nothing too major so far.

Thanks for responding.

Cheers
Phil
