I'm Fat and I bottom out

Recommended Posts

Well, Besides the typical response "Go on a diet you fat ass" I need some suggestions. I am about 6'1" and weigh about 230. I ride a YZ450F 04' and if I don't hit my landings just right my front end bottoms out fairly easy. What are some suggestions to correct this problem? :cry:

The quick and easy thing would be to add oil to the forks (see your manual in the "Tuning" section).

If you're still running the stock springs, I believe you'll find some improvement by going to the proper rate for your weight.

Correct springs for you weight and add another shim to the LS section of the base valve.

742,

Shims are what are used to change the resistance felt by the fork oil... they help determine the "feel" of the suspension. They are what tuners rearrange when they "revalve" your suspension.

The LS section is the Low Speed section of your base valve. If you look on the bottom of your forks where you adjust the compression damping, you will see a hex shaped recess where the adjuster is.

If you were to remove this, you would find the base valve.

At this point it sounds like it would be easier for you to try adding oil to the forks and learning as you go.

Try going here . It's not the exact fork you have but it's very close and will offer some more insight.

:cry:

I had an 02 yzf 426 and weigh 235 w/o gear "A" class mx rider and was having the same problem .

You need .48kg/mm fork springs and mx-tech valving. I did this and it was more than a night and day difference, you will not believe how good it works until you ride it. Worth every penny.

Thanks for the info and boost of confidence. :cry:

By the way is this something that I should trust my local dealership with?

You should seek out a good suspension guy , Like John Curea or Jeremy Wilkey of MX-Tech. Most of the time , from what I have seen , the guys at the local dealerships know just enough to get themselves in trouble , They are good at putting stuff back to stock only specs.

      Hi,
      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!
      Thanks!

      Hey guys. I recently purchased a 16 yz250x and the first 2 rides i LOVED the suspension. Then the day before a race i reset all my clickers to stock and everything felt like crap. No plushness at all and deflected off everything. I now have a 5.4 shock spring for my 190 pound weight and dialed in sag. Any recommendations on where i should go from here? Right now the fork is 12 out on comp and 15 out on rebound. Shock is 1.75 turns out on hsc, 14 out on lsc, and 18 out on rebound. Any help would be appreciated!

      Today we’re going to be talking a little bit about automotive suspensions and how they work to smoothen the ride of your car. There are mainly three purposes of the automotive suspension system. First, they support the  weight of the vehicle. Second, they maintain accurate tire contact with the ground. And third, they absorb any shock that you get through the road when you hit a bump.
      Most modern vehicles come with an independent front suspension. Which means if one wheel hits a bump it does not disturb the other wheel. Nowadays, people use Coil Spring to support the majority of weight in the car. As it has a really good characteristics for absorbing any bumps as you go up and down on the road.
      However Springs aren’t very good at dissipating that energy. In fact that’s why you have the shock absorber. Which is there to smoothen out the ride and make sure the tire maintains contact with the road.
      In modern passenger vehicles the two most popular suspensions are McPherson strut and double wishbone style of suspension. The main advantage of the McPherson strut suspension is that it’s really cheap and simple that’s why a lot of manufacturers are moving towards this design. The double wishbone design allows the wheel to stay perpendicular to the body as it navigates a corner or as it goes over a bump. And that maintains good tire contact patch no matter where the wheel is situated. Another advantage of this design is that it can be made adjustable where you can control the position of upper control arms ball Joints.
