Hi there, sorry for the slow reply.. Not too good with keeping in contact with the Internet! I have actually. It ended up being the fuel in the end which got the second cylinder to fire. I also checked the plug gaps and reset them to .4 which made the bike run a lot smoother! Have booked it in next week to balance the TBs so it should be as good as new :) hope that helps!

I have been advised to buy the best quality fuel all the time .

Either BP 97 or Shell advance .

NO supermarket fuel ever ....

after swapping everything over & bobing fresh fuel in and checking no mice have got in anyware :shock:
The last 2 things i would play with are a compresion test to rule out a sticking valve & you mentioned the hall sensor,
I rode to a bike shop bought a new jacket ,lovely pice of kit, strapped the old jacket to the rack fired up the bike and BINGO :oops: running on one pot.
ended up with the bike in bits, pannels off, bits everyware, hand running along HT leads trying to get it fired up ( NOT RECOMENDED ) outside the shop pulling my hair out :cry:
Ended up putting it all back together and having one of lifes moste interesting rides.
One cylinder, then Two, then One & then five as it tooooooookk off,
Oh and that turned out to be the Hall sensor :wav:
Triton 750cc,Nourish 8 valve. 31 Years of blow ups and counting.
Ducati 750cc, White frame.

LOTS of SMILES & MILES

Twin spark engine!


So ! - have you checked both stick-coils on the affected cylinder!

Have you tried swapping coils between cylinders!


I have, unfortunately it's the same problem even with the ht leads swapped over. The spark im getting is a really strong one which Only confused me more!


It looks that way doesn't it, always forgetting the passwords.. I convinced myself i hadn't signed up under this username and here we are. Passwords recovered now ha ha!

Quick update, I fitted a de-cat, modified silencer and EFI chip on the weekend. Bike runs great but idles terribly so I'm taking it down to the tuners on Friday for a quick TB balance and check over. Ill also get them to fit a K&N and new plugs just to be on the safe side as ill (hopefully) start being able to ride her again now the weather is turning.

I've also fitted a integrated rear light but it seems whatever way i try the resistors around I cant seem to slow the indicators?? for some strange reason they go slow on the hazards though. Any ideas?

Yes do tell, I now have the same problem, although I haven’t had chance to do all the above checks yet. Just checked for spark which is fine. If injectors can be swapped will be doing that next

Ok I look like a twat, but in my defence I was on the search function with key word "injector" on my phone. It didn't show all these answers that i can now see on my laptop. :lol:

I suffered similar. Compression was down on one side. Turned out to be a small piece of grey deposit which had dislodged and was between the valve and the valve seat. I only discovered that after haling the head off and valve out.

Have you checked to see that you don't have a mouse nesting in the inlet tract.

If you have spark and fuel you must be missing air - yes? missing air = blocked inlet.

or it could be a valve stuck open or part open - compression test?
There would appear to be a surfeit of prolixity and sesquipedalian content today please do not use a big word when a singularly un-loquacious and diminutive linguistic expression will satisfactorily accomplish the contemporary necessity
