Reply To: MOT Day and running issues

[Darkvader]

Of course, At the time I didn’t have to restart because i was trying my best to keep rolling with the bike in gear. it was completely not doing what i was asking though until it came back at about 30mph, then was fine the good 5 miles back home even at 60mph, like it had to cool off for a couple of seconds.
It’s always had little starting gremlins though, when it’s cold it’ll fire up, then come and go for a few seconds and i’ll have to rev the bike for a second for it to start being happy to run, even on choke, i put that down to carbs originally but i’m not sure that’s the full picture.

To be honest it’s never been jerky or juddery, yesterday it was running fine the only thing i can see directly that’s a bit weird is the tacho being jittery at 8-9k. I’ve not had a flat battery or anything because i use a battery maintainer though the thing that made me think electrics is that the original owner had put a new battery in after a year and i’ve had another new battery (though i think that was more frost, we had a bad winter that year).

The engine feels completely smooth at the speed i was doing, it was holding well but the needle will go from about 9k down to 8k in like a uneven flicker over half a second or so. plus when i was stuck at 50 the needle was doing the same thing, even though normally it wouldn’t at that speed. I’m puzzled.
I’m not so much blaming the boots or coils as such but I’ve ordered them as well being that i would like to run the laser iridiums properly and I like having spares.
What i’ll do is i’ll hook up a camera to the bike and record how it’s running, try and get the speedo, tacho and the engine note for you, perhaps your trained ear will help.
Thanks Marcel.
