    Ok, I got a '08 Mazocchi 66 RC3 on the tandem.

    My problem is that it is topping out with a loud clunk.

    It is coil(spring side) and Air Assist on the damper side.

    It has Mechanical Preload, Rebound, Compression.

    I have the rebound turned up, so it is slower to return.

    Is there something I am missing?

    Suggestions?

    Have you checked oil-levels in the damper, or seen if the rebound shaft is intact?

    Just serviced it. Oil level too high or too low?

    Flushed out the cartridge....new 7.5w oil. New seals and wipers.

    Now that I look, I put in 240ml in the damper side and 235ml in the spring side.

    Per Marzocchi it should be 250 / 280ml.

    OIL LEVELS
    OIL QTY R OIL TYPE R OIL QTY L OIL TYPE L
    250 Oil SAE 7,5 - Cod: 550013 280 Oil SAE 7,5 - Cod: 550013

    I just remember from years ago that if oil levels were too low, the rebound would not work correctly.

    Also how much air preload are you running?

    But dont go overboard, the oil levels need to be within a threshold, a height or volume I dont recall anymore.

    Yeah, looks like I am 10 cc's low in the damper side and 45 cc low on the coil side.

    I have no clue about all that stuff. I never open my fork. I just twiddle with the externally adjustable stuff. I know that Marzocchi killed themselves with some Sh!t product around that time frame - when ever Tenneco bought them and shifted manufacturing to Suntour. They recovered in 2011-12 ish with some great stuff, but the damage was done. no more OEM, no longer a player in the field.

    It sounds like you have a good game plan, based on the tips @riiz supplied above.

    Yeah if you google the Marz 44 Ti 29er at 2009/10, there were reports of fish oil shipping in the fork.

    Rather than start a new thread....

    I need the suspension gurus to school me on suspension forks. I'm pretty sure my stock Fox Float Evolution 32 CTD on the XTC is on its last legs. After conferring with some others around here, I'm probably looking for a 34mm stanchion fork with 120mm travel. Unfortunately, I don't have a thousand dollars to spend. Someone want to steer me in the right direction?

    The intent would be to keep the Fox Float and learn myself a couple things by refreshing it. That way I'd have it as a spare when the new one needs service.

    Take this for what it’s worth and I’ll probably catch crap but oh well. I’m no suspension guru and I didn’t stay at a holiday inn last night either. I do however have a slew of bikes in the garage and I’d guess we probably weigh fairly close to the same. I’d say service your 32 and save some dough. For a 100mm fork and a guy your size and the riding you prefer the 32 is fine. I have a 100mm 32 on my hardtail and for what the bike is designed for it’s perfect. I could ride practically any trail around on it just not at the same speed as the 150mm Hightower fork. My 2 pennies say save your money apply it to a different flavor bike if you have the desire to change the speed and type trail you ride.

    So if I stick with the 32mm stanchion - I'm not really opposed to that, it's served me pretty well, but some have said the 34mm is noticeably stiffer - I'd still like to have a second fork just to keep the bike in commission while one is being serviced, or I'm servicing it myself.

    Given that, what do we think of the Rockshox Reba RL? I see Jenson has it for $500...

    My 130mm Fox Rhythm 34 was $219 shipped from the mother land. It is the best budget fork on the planet.

    I still say save your money. A new school pike can be had for $50-100 more if you know the right people.

    The 100 mm/32 fork is capable... Heck, I rode Cannell on one. But if you are going to spend some money, there are cheaper places to look... I found the deal on mine after @Ebruner mentioned that he had picked one up from bike components .de

    Check the condition of the top out bumper in both sides. A 10 year old fork might need new ones.

    That was 14 1/2 months ago. Wonder if @mtnbikej ever got it sorted?

    It's not perfect.....but it is better. Once I put the correct oil levels in and tinkered with some of the adjustments, it is not as harsh.

    With that said.....I'm still on the lookout for a replacement for that Marzocchi.

    Question for the suspension gurus:

    Is a little bit of adjustment knob wobble (grasp it in your fingers and move it back and forth) considered normal? The fork is a 2018 Fox 34 with FIT4 damper. The wobble is about 1.0-1.5mm.

    The knob also has some play in it when it's turned into any of the 3 different modes.

    I had a 2013 Fox float 32 that did that with the CTD knob for a year from factory. It worked fine and the wobble went away after I had it serviced a year later. No problems before or after. YMMV. Good luck!

    I had the fork serviced and the wobble did not go away. Time to reach out to Fox.

    My 34 Rhythm (2017, I think...) has no play in the knob...
