I just installed an Edelbrock Pumper on my bike and am VERY pleased with it's performance. It's much smoother and has a quicker throttle response than the stock carb. The only problem I'm having is with cold starting. I live in Northern Canada and this time of year the morning temperature here can get down around freezing (32 F or 0 C), and the afternoon temperatures aren't much better, ranging from 45 F (8 C) to 55 (13 C). When I try to start my bike in the morning I crack the throttle once, then hit the start switch, it'll then catch but stall, I repeat this procedure for about 5 to 10 minutes, it will then catch and stay running enough for me to give it some gas without it stalling out. After another few minutes It'll be idling fine and I'll be able to drive it without it stalling. Once warmed up it runs excellent throughout the whole throttle range. The exhaust is clear (no black, blue or grey smoke). I'm running a Pro Circuit 490 slip on and a K & N air filter. I have a Big Gun Evo-X that I'll be installing this weekend. Any suggestions on a better starting procedure or on changing the needle and or setup would be appreciated. Thanks!
