if my yz426 has an aftermarket exhaust cam?? i just recently bought this bike. i have no problem starting my bike(which no longer has the decomp. cable) it has the plug in the head for the decompression cable. but idk if it has auto decomp because havnt felt the difference between decompression and compression.. i've also never had the kick back that you guys talk about sometimes.. i guess im just a natural badass at strarting the beast (no B-W mod, no BK mod, no after market accelerater pump cover) for all i know, my bike could have the auto decomp cam, and possibly an intake cam..
