Dont know how many of you saw my first post regarding my '01 YZ426, but I will again mention that this is my first bike of any kind and I have basically no experience whatsoever. I have done quite a bit of reading on this forum regarding mods to make the bike more trail friendly since its proabbly never ever going to see a track. What I want to do is get the bike happier going a bit slower until my confidence builds up and I am able to safely get through the trees going a bit faster. As you all know the bike is really unhappy going slow, and to me the throttle seems extremely twitchy as the engine gets up to speed really, really fast. I have spent most of my 3 rides trying to get comfortable standing up all the time, and trying my best to keep my weight over the front forks, but I am having a hell of a time keeping the front wheel on the ground. I would really like to change the final drive from a 14/47 to a 13/50, but I am worried that although I can keep the engine rpm up a little higher while going slower, I am going to have even more trouble keeping the front wheel down. How much will a 10oz flywheel weight help smooth out the twitchy throttle. Will a flywheel weight make much difference at all? Would you guys reccomend more or less weight? I havent pulled anything major apart on the bike, but I am thinking I will just turn the weight myself as most of the kits I have seen on the internet retail for $160 to $200 USD and they consist of a $5.00 piece of steel and about 30 minutes setup and machine time. Does anyone out there have a weight kicking around thats not installed that could grab a caliper and give me some basic dimensions? Your guys advice and reccomendations would be greatly appreciated.
