I have an 04 S-Model with Head & Can pipe mod, air box mod tuned to perfection. The bike is eating batteries on a cold start situation. Every 6th cold start or so, it locks-up and shorts out the system with the battery getting the worst of it. It has never blow a fuse on this. What I think it happening is that the battery plates are getting stressed until the battery won’t hold an adequate charge any more. You need a solid 11.4 volts to get the Ignition to fire. I have been through several batteries with this. I have found that on a cold start, If I put it in gear and rock it a bit, moving the piston up and down in the bore, that it relieves this lock-up on cold start. it does not do this on a warm start. I was wondering if the bike has a compression release that may be malfunctioning. What else might be going on here?
