dirtbike killer Posted January 25, 2004 Report Posted January 25, 2004 I just got some new a arms, and want to put some negative camber in them. I dont know how much is good, or how to do this correctly. How do you guys adjust yours? I'm lost Quote
spoin39 Posted January 25, 2004 Report Posted January 25, 2004 Are the A-arms you got adjustable? If they are camber adjustable use a straight edge and protractor to get the exact amount you want by adjusting the upper and lower balljoints. Quote

dirtbike killer Posted January 26, 2004 Author Report Posted January 26, 2004 Good link Formulaspeed. What I really want to know is what a good setting for a banshee. I talked to someone in a banshee chat room last night that really seemed like he knows what he was talking about. So I went with a 4 degree neg on the camber. I hope it works out. I know it looks cool! Also I seem to have more wheel travel, so I cant wait to ride it! I ended out using my magnet degree wheel. I just put it on the inside of the rim. Quote
Blue Duece Posted January 26, 2004 Report Posted January 26, 2004 i think your talking about castor....camber is how much your tires are leaning into the bike a good 1/8 between both tires is fine......castor wise....-4.5 for mx and as much as -6 for high speed open riding, depending on your swingarm.......camber, just give yourself a good 16th on each wheel at about 60mph they will spread to zero...as you accellerate...when you make these adjustments use a pair of tiedowns from your grab bar to handle bars......that will help you remove the slop from your tie rods...done right you can let go of the bars at the top of 6th and still track straight with no shimmy....remember -camber is the tire leaning into the the bike...-castor is the top of the knuckle leaning back twards the back of the bike..and you realize that the upper forward adjustment on your aarms is the castor adjust its not in the ball joint, you need to turn it out to get castor you will see the top of the knuckle(or spindle) moving back, camber you can get from the upper ball joint, as the top of tire moves in the camber decreases creating negative camber....positive camber would be if the top of the tires move outwards past dead "plumb" use a level standing tall against your tire and rim to get the same thing on both sides..and read that link it will help you understand......

dirtbike killer Posted January 26, 2004 Author Report Posted January 26, 2004 I'm talking about how much to lean the tire in at the top. I thought that was camber?. The stupid instructions that came with the arm called it camber. I wwent -4 what do you think? Quote

Meat Posted February 7, 2004 Report Posted February 7, 2004 4 degrees is a good camber number. I have mine set at 5 right now, no good reason why, I just wanted to try -5. My caster is set somewhere around +6 or +7. I had my caster set at 4 or 5 when I ran a stock length swingarm. When I put a -2 swingarm on the quad, the 4 degrees of caster was not enuf. The steering was so quick it would throw ya off the quad if you were'nt hanging on tight enuf. It was downright dangerous, but it would turn on a dime. At high speeds it was even more dangerous. Squirrly dangerous. So I layed back my caster to somewhere around 6 or 7..... and found that perfect balance between quick steering and high speed stability. The more caster you add, the more stable she'll feel. More forgiving ride, but the steering will be slower. Its a tradeoff. Id recommend when your setting your caster to experiment with different degrees, if your running the stock lenght swingarm then +4 caster is a good number to start with. If it turns to quickly and its scary-squirrly when the powerband kicks in, then re-set your caster to up another degree to +5 and test it again. Ride it for a few days at each caster setting. I adjusted my caster settings about 10 times till I found the perfect setup. Get used to adjusting the caster, use anti seize on all the A-arm theads so you dont have to worry about seized bolts. You'll be a pro in no time, dont be afraid to try different degrees, camber and caster. This is your time to learn..... have fun with it, use common sense and good luck. Quote
