When I'm riding hard in the big bumps--It seems that the front end on my f7 likes to JUMP--and I mean vertical in spots when I hit the bumps. Not only is it dangerous in the trails--it seems like it slows me down because I'm in the air. I don't hear my front suspension bottoming out so I don't think that is it. I wonder if my shocks are blown--or maybe the light front just likes to jump up on me?

If you let off the throttle at the peak of the jump or whatever it will keep your sled level. Get back into the throttle when you land.

It seens everytime I let somebody try my sled the first thing they do is jump it , and they scare the hell out of themselves. They don't relize how lite this sled is.

Mine does this too...from day one so it's not the shocks. I was going to crank preload up front to see what that does. I agree, it does slow me down and scare me at times.

Its just the light front end.

I have learnd standing about midway on the running boards and leaning slightly forward helps.

I got a chance to really launch my sled last night and found that this sled takes a few seconds to balance its self out. I had only got 1 to two feet of air before and found it either tiped back or to the right side. Last night I got 5 to 6 feet of air about 25 - 30 feet of distance and It flew strait and didn`t pitch. Landed on a flat but it was in a snow drift so it felt sweet.

Here is a Pic of the sled pitching to the right up in Ironwood the first time I had it out. I was still in flight training.

he is not talking about juming the sled he is talking about when he hits BUMPS the front end bounces and comes off the ground quite a bit when he is not even on the gas. He does not need info on how to jump a sled but how to make it not bounce up so bad when he hits a BUMP not jump.

Make sure you set your rear springs fpr your weight & try moving the coupling blocks to the middle position from #1 it will help keep the front end down.

F7 standard. I also have experienced this sensation when going downhill in big whoops. The front will compress( not bottomed) and jump back up violently. I just sent my shocks out to be revalved. More rebound control and a little more compression damping. The front skid shock was completly gone in both compression and rebound and would bottom completly on stutter bumps at slow speed. I will let you know how the oil change and revalving comes out. If good I will also give out the name and telephone number of the suspension specialist.

my f7 sp sky rockets also. it seems as though you ca'nt hit steep inclines as fast as on the cross country zr without a violent straight up rebound. maybe this is the price we pay for less weight. :mellow:

:p JUMP THE BUMPS !!!!:p

I was just adding a bit and putting in that the sled Is light it likes flight.

The friggin tourque that thi thing puts down also contributes to its jumpy front end.

The torque and weight takes some getting used to for sure. I was putting it on the ramp to load into a buddies truck tonight (new purchase) and I wasn't used to the torque.... it almost put me through his backwindow! scary.. studs hooked the wood and she wanted to bolt! I'm sure I could have cleared the cab if I punched it hard L!


home and with new oil pump updates it's smoke'n like cheap whore on the corner! Cant'wait to get this first tank of gas/part oil through it and get it leaned out....

it smokes so bad it looks like it's on fire! plus it's missing a bit, running so rich...

For high speed cross country riding, you need more dampening and rebound valving, and less spring weight. I have the same problem with my snopro, and I am currently talking with CC racers to get some insight into how they've set up the F5 for CC racing. For sure, I will be lessening my front spring weights, and revalving. I am less unhappy with the rear...not sure if I'll change this or not.

YOUR PROBLEM IS NOT IN HOW YOU RIDE>>>> A properly set up sled should not bounce through the bumps:

Cat did not do enough R&D on shock tuning, specifically due to teh lighter weight of this chassis. The only real testing they did was on the snocross track, where you need the higher spring weights because of the excessive jumping.

it is all in shock valving together w/ springs your using and how tight you wind them... I tried the 02 snopro front w/the 02 sp stock springs in front and they are heavier than what came on 03 f7 sp . I also put the 02 cross link w/cc valving and the heavy springs that came w/ the firecat heavy duty spring update kit in skid. The sled changed its personality completely the sled rode flat and I mean flat, front stayed down and level no matter what I hit. It was nice for control and turning and the front did not dive, like I felt w/ pulling limiter strap up just one notch and running blocks in #3.. I liked no blocks,w/ limiter up one notch like Rob suggested but front still liked airing all the time. I think it proves that the valving just needs more rebound damping in front and center. It has nothing to do with weight of frontend, lift front it is plenty heavy..

Mine does the same thing..the front end will pop up in the air. My 01 zr800 did it as well. I would think that coupling would eliminate this? I wonder if the 02 zr's would do it as much. It seems the coupling block on Fseries does not do too much because they can be taken out with no noticable difference.

imo, the f is much, much worse than front end popping campared to 01zr8. The f is down right scarry at times. I'll revalue for next year. I wounder if the 04 are better. Are any f6 experiencing this sensation when hitting the biggest of bumps?

I found my front suspension was bottoming on the trails w/ no jumps. I moved the rubber bumper inside the shock to see how much travel I was using. Just going across a field the shock was bottoming with no sag in my front end, so my shocks are tightened up quite a bit. (about 4.5" of thread) I just sent all my shocks out to be revalved. I should have them in a couple of days. I stiffened my compression in the front ski shocks and loosend the compression of the front skid shock. We'll see how that does.

I don't understand. I do not have the problems listed as above. I have just loosened the front skid spring and everything else is good. No bucking NOTHING but a$$ kicking bump eating fun.



F7 Standard.
