From your desciption if it happens after a series of logs set up like railway ties it sounds like your shock is doing, what is refered to as (packing).If thats the case, less rebound damping is required.If after only one log you may have your compression to soft and the shock is blowing through the first part of the travel then abruptly slowing on the mid valving leaving you with very little residual but very resistent travel.

It is only after one log. GMP do you think this is my problem?

I put .46 springs in my forks and the rest is stock and they are great here in the rocks and roots.

Its hard to say because your depending on someone else's observation. Does the observation match what you feel? If what was seen is true, over one log, I'd say its a compression issue. Try less comp first as see what happens. Test on the same obstacle, same speed for consistancy.

Did you revalve the forks for the .46s?

Did you go up on the shock spring rate as well to match the forks?

[cladoo]

No I did not revalve the forks. The stock fork springs are so soft. The rear is just fine. Not soft at all, firm if anything.

Claude,

I suspect that if you had the forks revalved to eliminate a lot of the free bleed, you could go back to lighter springs. At low speed the springs are the only thing holding the bike up. Did your bike come with a 5.2 rear spring stock? I can't help but think that a 5.2 rear and .46 front might be unbalanced, as mine is really good in the rocks with the stock .42/5.2 combo. Everyone has different tastes though.

[cladoo]

I doesn't feel unbalanced. It does have the 5.2 on the back. I am new to fork revalves but I now I can do it if I have diagrams or pictures. I don't plan on sending my forks out as it is a hassle and the local guys are so busy fixing Showas and KYB and KTM's forks , plus they don't have any experience with Zoke's. I somehow remember a thread showing the forks and it's stack. Are the '07's the same or what has changed? My '06 was way softer on both ends then my '07.

[widebear]

I have to agree with Glenn on the point of balance. .47 are super heavy springs. To generalize I'd say .47's are for 250 plus pound riders and a 5.2 rear for a 170 lb or less rider. you all so need to add alot more rebound damping on the forks to offset the extra energy that will be stored in the spring on compression. You must be running very little oil in the fork in order to get full travel? What do you weight with full gear on?
