Testimonial: "Bit late but thanks... I did find out that it can be connected to one of the vacuum fittings on top of any of the carbs as well.. The ones you use to balance the carbs as long as others are blocked off as normal..."
First off did you buy it new? Second has it gone through its break in tune up yet?Did you do the re jeting? My guess is it was re jeted wrong & neeeds to be re jeted again or could also need more air(upgraded air kit) or a tfi or power comand fuel mod.My bike also poped untill I did the air & fuel upgrades & them upgrades will also give you a much needed house power needed for this rig.
Bring it to a shop & have it looked at.......

If the spark appears to be weak only for the two front cylinders, then I would suggest checking the electrical connections for the ignition coils.
If the spark for the other two cylinders looks the same (yellow), then I'd suggest checking the compression on the non-functioning cylinders. A compression reading of 140~160PSI is what you're looking for. Low compression indicates internal engine damage - or could be from something relatively simple - like insufficient valve tappet clearance.
If the bike has been sitting for a long period of time, it could be that the carburetors are plugged up with fuel varnish. This can cause some cylinders to not run. A complete carb disassembly and clean-out will be needed.

Testimonial: "thanks for that feed back . there is plenty of fuel and compression is non existant on front left and 80 psi on front right,I suspect cam wear????"
I cant quite figure out which spacers you are refering to. The only thing I can think to suggest is the exhaust schematic on bikebandit.com. If I knew for sure I could try to look at my bike but there's no telling what previous owners could have done. Sorry. I'd really like to help.

This particular model uses a BS36ss carb for the # 1carb or back as you are calling it. there is an input and output as a pass through to the second carb intergrated into the fuel delivery system of the # 1 carb. the # 1 carb draws fuel from this port also. check for obstructions at this point where the 2 carbs intersect and in the transfer line to the front carb remember this is a neg. pressure regulated fuel system so any leaks at carb 2 (Front Carb) or Balance Tubes Between cylinders and it wont function . vacuum is the key
