Ah, OK, now I understand. Can't help with pumpers soz!

What you upto Kev? Got to be pumpers? I could probably scrape together a set of 26 knackered non pumpers if of any use?

You need to mount the coils directly to the frame using the 2 bolts. The heat is dissipated from the coil core, the big metal bar running Through the centre, via the bolts to the frame. You shouldn't insulate the core from the frame or it'll over heat and fail having melted the windings insulation a...

I don't see why not. They are seperate circuits for each coil so I don't see how they could affect each other.

Dyna runs fine on oem black coils. Maybe swop them both back in and test run. If the fuse doesn't blow you have your confirmation.

I doubt you've broken a ring and think your issues are either timing or carb settings or both. Your comp tests are probably a red herring which are mainly down to sealing issues. Static time it and set the airscrews at 1 & half turns out from seated and you'll no be too far out. Report back afte...

It depends where the ring has broken (if it has). If it's broken into 2 half's then it'll do little damage to the bore as it wouldnt be able to twist in the bore that much. If it's broken say 10 - 15 mm from the gap the broken piece would have more room to twist and would score the bore badly if tha...

OK, firstly the inductive strobe pick up. If it's on in the wrong direction for that ht lead you'll get an intermitant signal / flash. The airscrews are on the side if the carb. Think of it as a tube which is partially blocked by the screw. Opening (turning a/c) reduces the blockage and allows more ...

This explains it clearly Al. Follow the arrow directions although in our case it would be plug 1 & 4 and 2 & 3. I've had this conversation with Graham previously.

Just cut a new one from an old inner tube. If you don't have one your local tyre fitters will have plenty in the rubbish bin.

Glad you made it nik

Fingers crossed.

Yeah, the ones without are pointless (excuse the pun )

r3sc, one proviso, Graham has the replacements that have a adjuster for each points set aswell as adjusting thing the back plate. Many repop plates don't have the adjusters on each set of points.

Hmmmm, cylinder 1 & 3 looks a little suspicious. 1 being lowish with no oil and 3 having a big increase with oil. Cylinders 1 & 4 are normally fairly equal as are cylinders 2 & 3. Cylinders 2 & 3 are normally a little lower than 1 & 4 as they are in the middle and get less coolin...
