marzocchi oil ?

[sonquizzon]

I have the marzocchi forks for my KLX. Do I have to get marzocchi oil or can I use some other oil when cleaning them up?

If anyone could recommend an oil weight also- I weight 175.



Thanks.

Marzocchi Recommend 7 1/2 Weight

dont bother with getting oil from marzocchi, it's not as good as the others like bel-ray, also if your riding hard go to 10wt.

The Marzocchi oil is Golden Spectro 7.5 wt Cartridge fork oil. It is also called 125/150 in some places, its the same stuff. You can use any fork oil, as long as it says NON-SEAL SWELL and is a NON-PETROLEUM BASEd oil. Any fully synthetic oil will work, just make sure it is a cartridge fork oil for Motocross bikes.

BTW- if you are going to use a differnet oil made by a different manufacturer from what is in the fork (no matter what oil or fork you have), be sure to drain all the old oil out and clean out as much of it as possible before putting the new oil in. Not all oils will mix thoroughly and can feel weird when you get to ridin a long moto

I have the right fork leaking oil. I got the seal kit, from what the manual says that could be my issue. I hope I don't scratch anything!

[ridered29]

make sure to bleed the fork often, if you dont the pressure that builds up in your fork while riding will prematurely blow your seals. Try to bleed the fork at the track before each time you ride, its the phillips head screw on the top cap of the fork for the 35mm inverted kits, it takes 1 minute to do both TOPS and will save you $$ on seals in the long run.

FYI-when you press the seal into place, use the slider of the fork to press the seal in like a slidehammer. Move the fork tube, not the seal driver.

oh yeah, use an oil height of 70mm from the top, fully compressed and the spring removed. mesure from the top of the slider, right where the top caps threads onto

marz says to fill with 230cc of fork oil. i just did mine.

Hey Sonquizzon, sorry to jack your thread but I got my bike a couple of weeks ago, took out the motor and shipped to Eddy at Moto HP. He got it yesterday and is in the process of working on it, making the Frankenstein 180 out of it. So, once I get it back, we'll have to go out riding!!!

Forgot to mention, Dave is having a race at Speedworld on 11/19, want to go??? They have pitbike races and vintage along with modern bikes now so pretty much any bike you have, you can race there. It's usually a tame track so good for all old guys like me!!!

[ridered29]

cool,i wouldnt recommend using the 230cc oil measurement, but if it works, awesome. Volume is inaccurate and is easy to throw off if you have any oil hiding out in the fork, even 10-15cc can throw it off. oil heoght is the way to go if possible...

[sonquizzon]

wow! well thanks ridered29! sounds like you are familiar with the process... I have $50 towards your services- haha! Seriously, every bit helps and you all give some good advice. WHat do you measure the height with? Does 70 mm equal anything in inches? I don't have a tape measure or anything with mm.



mtnbykracr- sounds cool the 19th. What track? I think I did a race there the 1st time their pitbike track was built and it was all jacked up. We should ride before if we can, I would like to see how bad I would suck out there so I can prepare myself- haha!

just take your metric measurement and devide by 25.4. That will give you what you are looking for.

example

80mm of oil height devide by 25.4 equals 3.14 inches.

Hey, I know Ridered29 is an EXPERT on this stuff, especially if it's from Marzocchi!!!

The track is at Speedworld on the vintage track, not the National track! It's not at ET motopark. You can check out the schedule at www.avdra.com I believe. His site says 125cc or less and 16 inch wheels or smaller. Just don't tell him if you have a bigger engine!!! Talk to you soon!

[ridered29]

thanks boys, appreciate the kind words... been busy at the shop lately and just jumped in here to help.



The best way people measure the oil height is by tying a zip tie to a washer and using it like a dipstick. just mark a few 10mm incriments with a sharpie, and be on yer way. the 70mm oil height can be adjusted +/- about 10mm up or down, so try it there first then ride to see if you like it.



TIP--- More oil=stiffer feel (quicker progression rate through stroke). Less oil= Softer feel (more linear all the way throught the travel).

Hey Ridered29, do you know anything about the bottoming cones on the zokes? I.E. does Marz sell something for them, I don't think they come in them stock do they? Do you see any benefit? I just got a new bike and it has the new double/adjustible legs. I haven't ridden it yet but my last one had bottoming problems and I didn't like the "hit" that it had when they would bottom. Just curious what's the best way to help that? Sorry for jacking the thread again Sonquizzon!

[sonquizzon]

Take it away... I'll learn from your questions too.





Vintage track- ooohhhh I saw that there- looked a lot more fun. I'll check out the site.

[ridered29]

the 35mm marz forks dont have a "bottoming cone" in them. I havent seen anything come through here with them, (the marz 50mm and 45mm forks have them for the big bikes) but i guess if they fit and dont interfere with the fork then they are OK.



To help out with bottom out just check your oil height, if you are getting metal-to-metal feel at the end of the stroke your oil height is too low. look^^^^ for oil specs.



If the hit you are talking about is more like a Hydro lock out, remove some of the oil (about 10cc to start) and try it. add a few clicks of compression so you dont blast through the travel.



BE SURE TO BLEED THE PRESSURE OUT OF THE FORK often, or you will blow seals and the fork will feel too stiff at bottom out. Do this with the bike on a stand, the wheel hanging, and just loosen the bleed screw until all the pressure leaves, then snug it back up. dont lose the screw. dont try to take it all the way out and hold it. dont play with the screw. dont suck on the screw. Just bleed the air and snug it up.

use like 5wt, but put in stiffer springs, that would be the best way, u spent all that money on zokes, u might as well make them right

Ridered29 is the old tech from marzocchi.
