First of all, i would like to thank wookie 58 for doing the repairs to my relay. Very much appreciated.
put it all back together today, but unfortunatly it still wont start. I'm not sure what the problem is now. At first it looked promising. I heard everything click into place, but no, still struggling.  I think its getting to much fuel as it started dripping out of the drain hole in the exhaust pipe. I think the injectors are sticking open, that's my theory. It must be an ECU problem. Probably why it's been parked up all these years

So plan b it is. What is a good set of carbs for this bike, and where can I get some.

Yes, i have basically checked every thing you can test and all was within speck except the relay, which you repaired. When I put it back on I could hear everything clicking into place which gave me hope. But it did the same thing, it would fire up for several seconds then stop, then nothing. I would turn the ignition on and off, and no response from the electronics. The only thing you can't test is the ecu, so it must have a fault. So I'm going to source some carbs, so I need to know what are the best. I have read that VM28 carbs are a good match.

Sorry not been online about this problem, i had a commission that needed finishing.

Right, I have decided that the fuel injection system is coming out, and going to fit carbs. What type of carbs can i fit to this bike, and where can I get them.

As I recall, the port spacing is the same on yours as on all other carbureted 900/1000/1100 engines, so you can fit a used set of stock BS34s or an over priced set of 29 smoothbores, or some brand new Keihin or Mikuni carbs. Webike, APE and Dynoman stock new ones.

There should be an old thread or two around here on that topic. Maybe archived???

Also don't forget that if the injectors are mounted in the head (I don't know on your model) you will need to get some blanking plugs made up to fill the holes when the injectors are removed

Howdy peeps, 
took the good advice and purchased a set of BS34 carbs. They are surprisingly in very good condition, but, as to be expected, the o rings need replacing. Have looked on the Internet and can't seem.to find anyone that just sells o ring sets. Also I need to replace the intake manifolds. Any suggestions where I can find said items.

Howdy peeps,

Just a follow up on this saga, the bike is bike running, needs a tune up, other than that, well happy. 
just a question, the emissions system on it, do I need it, or can I get rid of it, also there was a slight poping coming out of carb no1. Could that be a sign of it being a bit lean or an air leak, or even that crapped out emission system.

You can delete the emissions system (there are several posts on here relating to this)
