Hey Guys,

I am new to the message board and been having some issues with my 82' XS400J Maxim. I got the bike when it was in bits of pieces and have so far restored it to get it to running condition, except to find out that only one cylinder is firing. I have ripped apart the carbs, airbox, etc a bunch of times now, cleaned and rebuilt the carbs, but still seems not to be getting fuel into the first cylinder. I have also had new spark plugs, checked the spark, etc, and have run out of ideas, So I am open to any responses. Any help will be greatly appreciated.

Thanks

do you have compression in the cylinder and spark. Also check the valves for proper clearance. also check the timing did you check the carb diaphram for small holes which are very hard to find sometimes. these carbs use vacumn so anything causing a vacumn leak or blockage can cause trouble good luck

Welcome Max....have you sorted your bike out yet?

Cheers!
