Is it a loose coil connection causing your misfiring issues?

I'm on A 600 Mike. Number 33

Even though a guy I asked said he wouldn't take his wheelbarrow to him, there's also the guy at Northallerton.

Have you changed the plugs? Checked the coils and leads for spark leakage? A high speed misfire could also be fuel starvation. Check there are no kinks in the fuel lines. If there are any filters in your fuel lines try running it without them to see if they are causing too much restriction.

Doesn't sound like the carbs but I'd clean them out (including all the jets) and check they go back on without any air leaks in the rubbers.

Good luck sorting it!

We'll im having a good strip down this weekend (the bike not me !)

right just had bike on dyno. much to my surprise it was running lean, weve took the factory pro 140 jets out and put in the 145, gave a lovely smooth curve upto 68bhp at the wheel. flattened off at high revs so biggers jets would get more BHP.
Im ordering 147.25 and 150, mebbies even 152.25 jets from America,
So the bike good to go for eastfortune this next weekend, then i'll fit the biggers jets and dyno it again later in the year.
by the way when it was missfiring it was making 55bhp !!!!!! and i was wining on that at Cadwell !!!!!!!!

Re: just started minitwin with NEMCRC and Derby Phoenix
 

You're ordering jets from the US?

Can't you get them here?

Glad you got it sorted :)
