Thanks! It took me 7 months to find a bike, slim pickings up here for anything not beat. Paid a bit more than I wanted ($2900) but the bike looks like it just rolled off the showroom floor. Got some riding in this yesterday, still running great and had a blast. I thought I had ok bike control from racing motocross and riding enduro but it turns out not so much (haha.)

Just tried it, fired right up second kick. I guess I should have realized it traveled that far when I took the carb apart, I kept think I was going to snap the level pulling it up much beyond where I felt resistance. Thanks for all the help guys even if it was my own fault to begin with. If anyone is ever in Southwick, Mass for the mx national I'll buy you a beer!

Below are two pics of the carb just to give you an idea what is on it. Choke is oriented in what I understand on the on position (up).

So I came home (its in the lower 40's outside) and tried kicking the bike, no dice. Next I tried laying the bike on it's left side for 5-6 seconds as suggested, gas pours out the overflow so I know the inline filter is not plugged as well as the filter on the side of the carb (which I inspected and was also clear when I cleaned it.) I think this should also indicate the float isn't sticking? Kicked it a few times and the plug was dry. I tried laying on its side a few more times and plug dry both times when I pulled it. I also tried tapping on the bowl. The gas came with the bike and smells fresh, it is 91 octane (non-ethanol) mixed 80:1 with Maxima K2. I may trying pickup up some AV gas tomorrow to see if maybe it will atomize better but this still points back to some kind of carb issue to me (or user error?) Still has good spark and compression. As I mentioned it has started on the first kick for me after sitting a night in similar weather. Saturday it started after a about 40 kicks, stalled when I realized I had turned the gas off when I was messing around then started again after about 30 kicks. Then ran perfect for the hour of riding and started hot fine. What could I be overlooking in the carb? Gas should have a straight shot into the intake and crankcase with it layed over, if gas is pouring out of the overflow, right? The choke does not click on, right (like a keihin on a mx or enduro two stroke) you just adjust it to the up position and there is no positive "click" type engagement? I didn't want to break it putting to much force on it. Thanks again for the responses, your support is much appreciated as I'm very puzzled.

I recently purchased a 2006 Sherco 2.9 a few days ago. The previous owner kept it in his heated basement and apparently had no issues with it starting, he said it almost always started the first kick. I am located in Western Massachusetts and the weather has been somewhere between 15 F and 40 F the last few days. The bike is kept in my garage that usually stays just above freezing. Everything on the bike appears stock. Still has the original tires and I doubt it has much over 30 hours based on the condition. The day I brought the bike home I could not get it started (15 F outside), I pulled the plug and it was wet, I'd assume fouled. Didn't have much time to fool with it so just left it with the plug out. The next night I put the plug back in, garage was in the mid 40's and the bike fired right up on the first kick. Bike sits for a few days, it gets cold again and does not want to start. I check for spark, spark is good, I try swapping plugs, no luck. Plugs are dry when I pull them. I layed the bike on its side and drained some gas out of the bowl try kicking a few times, no luck. Pull plug, still dry. I try it again with the gas off and it fires the 10th kick and stalls, a few more kicks and it starts and runs excellent for my hour ride. The air temp was around 35F. The next day, today, I go to start the bike and it doesn't start (upper 30's). Check spark, good. Bike has a ton of compression. Plug is still dry each time I pull it. I decided the pull the carb off and clean it, everything looked ok but I pulled it completely apart and cleaned everything. Tried tipping it over and pouring some gas out of the bowl, etc, still does not want to start. Plug is bone dry. I checked the stuff I read in similar threads, plugs are gapped right (BP5ES at .020-.023 gap, BPR5EIX at .023-.025), pilot jet was a 33, I forgot to right down the other jets. It appears to me to be a carb issue. Are there any other tricks I should be trying or looking at? This is my first trials bike (first sherco as well) but I came from the enduro and motocross world so am a bit puzzled by this, hoping you experts here can help! Thanks in advance!
