Hey guys! Got a question or two for you. At the track, whenever I'm setting up for a turn and start hitting the square edged braking bumps going in (I'm decelerating, but it does it while accelerating too although not as bad), the headshake attempts to yank the bars from my hands! By the third or fourth lap, I'm so tired of fighting the bike I just cruise into the turns. I checked and greased the steering head bearings today, tightened the steering head up a little(bars won't turn to the side by themselves when bikes on the stand) so it has a little friction (they may have been a little too loose before), went through the front wheel procedure to rule out binding, and dropped the forks in the clamps from 9mm to 5mm. Is there anything else I can do?
I'm 185lbs. and a novice mx rider. The track I'm riding at is basically a sand pit. I bought the bike (01kx250) from a dealer that used it as a demo model. He said he put the next heaviest springs on it for himself (he was about 215-225lbs.). How can I tell what these are? I recently changed the fork oil (100mm) and couldn't find any numbers on the springs. I can't see any numbers on the rear shock spring either. According to the spring rate conversion table, my forks should have .44 springs stock and .42 for my weight. Why lighter? The rear shock is .49 stock and it recommends .496 (.50?) for my weight. That's pretty close if he put on the next heaviest.
I bottom the rear end a couple of times almost every lap so it should be soft enough in the rear. I've never bottomed the front but it comes pretty close. It rails pretty well in the turns, although sometimes the front end wants to push out. The front end also wants to dive down into the whoops even though I stay on the gas. I track pretty straight through the whoops (aside from the front end diving) and have only swapped through them a couple of times. I can't keep the front end up though! It stays level when getting big air (no pitching forward or back unintentionally). Hard to track straight on level ground (fairly deep sand) but I consider that a byproduct of the terrain I ride on (I assume). I put Dunlop's 733's front and rear on yesterday, rear and front end bites pretty well. Small bumps (mostly square edged) kills me though! Can anyone help with this?
