Just recently purchased a 2019 Honda foreman 500. Bike came with snorkel, lift, tires. Besides that everything else is stock. When out on the first ride it shut off as soon as the plug and exhaust went under water. I tried the dielectric grease in the boot and still keeps dying. I read somewhere that back pressure on the stock exhaust is the culprit? Is this true? If so what exhaust and tuner would you suggest? Not trying to be loudest out on the trail or blow $1000 on something that wasn’t the problem. Anyone else having these issues!?!
