Ground clearance issues on track

I ran my 426 on the race track for the 2nd time this weekend, but I found that I ran out of ground clearance fairly quickly. I almost had several high sides when the pegs hit the ground so hard that the rear tire lost traction. Has anyone found a solution? I am running 4" shorter suspension with stock wheels, Conti pro dual sport on the front and a goodyear DTII, CD5 on the rear.

^This is your problem^

Did I miss something? How can you lower the suspension by 4" just by changing tires? I've never measured but I don't believe that the stock Dunlops have that much profile. Betty needs another slap.

I *think* he means he has lowered the SUSPENSION travel 4"...as in modified...of course tires on stock rims can't drop it 4 inches!

:):D

I would have to say that when you lower your bike 4" you might have a ground clearance problem. How are those tires working for you,a little slippery?

It sounds like you're not riding MX but you're riding onroad or dirt track (I'm not familiar with the tires that you mention so I'm guessing). Is this the case? I wonder if a suspension shop would be able to help you stiffen it up enough to prevent the problem but without making it harsh?

I was at the road race track. I have two sets of suspension, one for the woods and a shorter/stiffer set for ice racing, road racing, Pikes peak hill climb. If you want to see photos of the bike on a road race track www.12pointracing.com in the gallery section. aside from loosing ground on the straights we could catch slower R6's in the twisty stuff. I measured my road racer and it is narrower and taller to the pegs than the YZ so I will probably have to cut down some pegs or raise the bike back up some to keep from dragging.

He sounds like a roundy round flat tracker. He may need to unlower the suspension a bit, or stiffen it, or raise the footpegs.
