Hi there, I've browsed through a bunch of threads and cant find any answers. My 2011 zy450 stalls at the most inopportune time- and it's really pissing me off! I came off an 08 yz with a z-start and that bike would never stall. I've got the GYTR tuner and have tried many settings and non have alleviated my problem. My valves are in spec..I run premium pump... besides a rekluse clutch which will only decrease the amount of times it stalls; what are the offroad teams doing to prevent it? I mean, Paul Whibley couldn't possibly have this issue... He's winning and that wont happen if you stall! His bike also starts on the first kick! Heavier flywheel? different ignition? Rekluse EXP or Z-start? (still stalls with the z start) If you have any ideas or links to other posts please hook me up!!!
