I had an 01 426 and it had a hesitation off idle. The bike threw me in a 6 pack (3rd gear) set of large loops, when coming off the second set of woops I gassed it and the hesitation occurred causing me to face the next whoop and throwing me over the bars. Didn't get hurt, but traded the bike in on a RM250 the next week. I wreck enough without the bike helping me like that. I heard the 02 426 fixed this problem, but I keep hearing you guys talking about the BK mod. Was this mod supposed to fix this problem or is it for something else, or was the problem fixed when the 02 came out? Just curious. I loved that bike except for that problem.
