Cold starting
« on: June 08, 2014, 11:04:06 PM »

X wont start on the kicker from cold ? bumps ok after a bit of a leg it  :o and starts on the kicker no problem when warm.

I threw some b8hs at it tother day but has not helped the situation. when it does start up from cold,its excessive smokey,compared to my 400f which always starts 1st 2nd kick.

Any ideas chaps ?

Iridium plugs? Bit dear-ish though @ £10 each...
I think it has the Zeeltronic iggy, so not the easiest thing to check

When mine gets like that its usually the plugs getting a bit old.

Putting a new pair in transfors the starting

I usually go 3 years a pair (5 to 6000 miles'ish) - How old are the set in there now

There a year old Del, they were put in on the engine rebuild last year.
I think Hazy has already put a new set of B8s in and its still difficult to start from cold.

Howz the battery then.

Similar symptons to mine when battery was on its way out. Have you tried putting the battery on charge overnight then disconnect and try to start from cold.

Fresh fuel tother night.

I will use it sunday for the car/bike show in exeter,so see how that goes.

Its also got a oil leak from gear lever shaft,i dont have a spare seal here,so will keep the gearbox topped up.

I assume the choke is actually working (choke on with warm engine, engine dies)

Any sign of an air leak?

If the bike has a zeeltronic system fitted you must use Resistor plugs. ie BR8ES OR BR9ES.
