Help with marzocchi 45mm
 

Goodnight I have a 2011 gasgas 300 with marzocchi shiver forks I've messed with them a lot, but whenever I ride the bike they make my hands sore I tweaked the valves, softened the compression, stiffened the rebound, I'm using 7.5w oil and things have improved, but I'm still not liking the forks. I weigh 65 kg, I wanted to do the best I could, but without messing with the springs

Springs are ALWAYS the starting point for getting a suspension dialed in correctly. Without the correct springs I highly doubt you'll ever get it where you're happy with it.

With mine it was my arms and elbows in particular that took a beating on the rough stuff. I was getting worried that I really wasn't able to ride those sort of rides anymore.

A set of YZ250 SSS forks fixed that. Although you will need softer springs and a revalve they are sophisticated enough to bring you joy. We just did a mates 2010 and he was impressed.

Revalved zokes didn't get me near, although did help with tree root deflection. SSS are better everywhere. Search for conversion threads. Or upgrade to a later GG with the KYB SSS forks fitted std.

I understand perfectly, but I'm not willing to spend a lot on these forks, so I think it's more feasible to buy another one that's more up-to-date. I just wish they would stop hitting my hands so much, even on small irregularities.

Maybe try Flexx Bars.

Can you reduce the spring preload and remove some oil to reduce the air spring.

Or Twisted engineering. Pricy, but good. I have had mine for at least 8 years without any worries.

I bought my 2011 EC 300 new and I sent my forks to Drew Smith at Works Enduro Rider. He revalved and resprung them and installed SKF seals. They are smooth and progressive and I have have never had a problem with them. I am still riding it with the same setup now.

Can you tell me what was done to yours? I would like to copy to mine

I rode the bike today after putting the 7.5w oil at 130mm. I was happy with how it handled the big obstacles, but the road rib vibrations were too aggressive in my hands.

I live in Brazil, it is not possible to contact this company

Try softer grips.

I suffer a lot less from wrist pain and calusses now that I ride with very soft grips (full waffle). Mind you, it's not for everybody since its a different feel of the handlebar, but you can get them really cheap without further venturing into the suspension set up.

The con: I change them every 10h or so, they tend to gain holes or desintegrate due to the friccion with the gloves.

If you reduce preload on the spring you will soften the initial part of the stroke and it should help address your problem.

I just wanted my forks to work well, it doesn't have to be a specific setup for me. But they are very bad on the roads

If you want it to perform well then it must be setup for you. That's the whole point of different spring rates, weight of fork oil, and different valving being available.

It Takes Some Time and Effort
 

Yes,that is correct.:)

Is it possible to get a good adjustment on this suspension? I'm disappointed. she's new and I don't like her. even motocross bikes with suspension for heavier riders are better than my bike on the trail

We've all pointed out what you can possibly do and/or should do to make it feel better. Have you tried those things?

Set the compression to 15 on one side, 12.5 on the other, reduce the rebound to 7 on both. Then fit some KYBs that are actually sprung and valved for your very light weight.

Summary to you question; no. If the rest of the bike is good - it (fork swap) is worth it. If it is a worn out 12yr old bike then it is not worth it. Start saving.

Week before last I had a great weekend riding my old but rejuvenated 07 which has better suspension than my 2021 beta.

the spring that comes on the suspension is 0.42 and the ideal spring for my weight is 0.40, it's not that far away. like i said even motocross bikes with heavier springs are better than mine. Assuming that my spring is for 75 kg and the suspension is good for 75 kg, it would suit me too, it would just be a little stiffer. What I'm saying is that the suspension doesn't work well. Oil is 7.5 to 140mm I'm only using 4 shims of compression and even then the suspension rarely reaches the end of the stroke.

I'm thinking of installing the race tech gold valves and seeing if the suspension works acceptably, otherwise I think the solution will be to change them. I looked at a 47mm show on ebay and the value is attractive. I think even the original ones would work better, then later I change the springs and do the race tech genetics on them too

Ok, these are a few things I've done to make my forks to eat up the small chop.

Try going to a 5wt fork oil. That's what I've run in every fork I've owned including Showa, KYB, and Marzocchi Shiver 45 and PFP48's with great results. Run your outer chamber with just enough oil to keep from bottoming hard and run zero preload on your spring.

I was 130mm now I'm down to 140mm I'll try. The spring preload has not yet been adjusted, it is original My compression pants are 22,19,17,15(0.1) it never reaches the end of the course, it's missing about 2cm. I'm going to walk and see if with the lower oil it works better in the course
