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.
Phil

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.

Cheers

Singles / Scavenge Valve Replacement
« on: 29 January, 2018, 16:32:34 »
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

Mine doesn't have one of those. From  the pictures I've  seen  it is part of the engine casing.  I've  since found pictures of  others  that are like  mine so wondered why some have feature and some don't.

Didn't know if it was something added or removed at some point in the manufacturing run.
According to the engine number my bike was made in May  1970.

Singles / B25.Starfire - Tachometer Question
« on: 17 December, 2017, 20:37:32 »
Hi,
I recently  bought a 1970 starfire. It's in pretty good condition but has enough things to do to keep  me busy over winter.
 
The model I have has a single speed but I have noticed that some Starfire's also have a tachometer.  I thought this might be a nice addition but when checked my bike there is no connection point. 

Looking at some pictures of Starfires online I can see a connection  point just above to the right of the oil pressure relief valve but on mine there's nothing (see attached  picture).

My question  is,  should  there be one or was it only on some models?

Cheers
Phil
