Missing on cold start

[TLS_Ben]

I recently rebuilt my TLS after a gearbox failure (Suzuki has superceeded the gear that broke - mustive been weak). Most of the time when I start it up in the mornings it will only run on one cylinder for about 5 seconds - then the other will light up, but miss every now and then, also giving big backfires untill it's semi warmed up. It had new plugs put in it about a month before I stripped it down - any ideas anyone

Are both plugs gapped correctly? Are the plug wires pushed in all the way?

TPS set correctly?

what plugs ya got in there? cr8ek or cr9ek? that and how old is the gas in the tank. i am assuming at least a month.... has it been humid by you? you might want to drain the gas, ans put fresh stuff in. it loses volativity after a while, and also absorbs water...
