I always figured it was normal to have to pull it 8-12 times to get it to fire after sitting for a couple months. Then I got my self another sled and it fires up in 2-3 pulls after sitting the same amount of time. My Vmax is a stock 93 jetted for 5000 ft altitude where I ride. My other sled is a 96 Mach Z 780 jetted for the same altitude. My Vmax starts first pull when warm and on 2-3 pulls from dead cold after sitting a day or two. If it sits a few weeks my shoulder takes a beating to get it to start. Where should I look I To cure this problem?
