I'm new so if this looks sorry that's my excuse... I've read post here for quite a while, especially before I buy a bike. Now the topic, Kawasaki Super Sherpa. I've read a lot about forever warm up times, hard starting, stalling etc... And the remedies, jetting etc... I've had mine for a while. It used to be very difficult to start and stay running before it was completely warm. But I did something novel, I read the manual. It seemed to address the hard start. Mine never takes forever to warm up regardless of temp outside. This is what I do and did: 1. Tighten the choke knob at handlebar by twisting base so it stays on choke, directions in factory manual. 2. Make sure idle is set at proper rpm, in manual too, I think it was 1,200 rpm. 3. Before starting turn gas tab valve to prime, wait 10 seconds, so it can drain in carb and break vacuum in tank 4. Pull choke out 5. Press start, let it make a couple cycles of compression, no more than 5 seconds 6. A tad of gas when it fires. It will idle high with choke out 7. Pump throttle a few times, half choke, pump throttle gently, wait a couple sec, put helmet and gloves on 8. No choke, throttle a tad... It should sound good not like it's dying 9. Put fuel tap to on. Ride! A note, after a motocycle mechanic of 35 yrs told me to only use 93 oct gas on small engines I always do in my bikes. Also, when bike sits for more than a week or two I add stabil to tank and drain carb. When winters over, the Sherpa starts first time, warm up is never anymore than a min, regardless of temp. I'm not a motorcycle engineer. My personal opinion is you gotta put that tank on prime when starting and break vacuum and have choke all the way out. I hope this helps those out there that want to keep bike stock and wonder why it won't stay running until its been 10 min.
