Wondering what the air gap is on the ignition pick-up coils. Also be interested if there reading changes when they are hot after running the engine for a period of time. At 97 ohms they are already a bit on the low side

I missed the trick of letting the bike stand running to get hot and then re-reading the pick up resistance. Hoping it will be running AOK for Pembrey

:)

Today at Cadwell I was in the holding area, I noticed the idle revs were down from normal. Pulled the vert plug lead and the engine stopped. On part throttle it was running on 2 but not quite as crisp as it usually is.

Compression test revealed front pot 25psi down on the rear pot. So I took the head and barrel off, signs were running very weak. Then I found a large split in the carb rubber right under the Jubilee clip.

Better to find on a TD than waste a race weekend tho'.

Met a lot of faces today for the first time, good banter with everyone. :p

You'd think that with all these problems with 17 year-old wiring, diaphragms, mixture screws, igniters and the like, you would get more people out on the 9-or less year old 620s.......:lol:
