How much front fork pre-load?

[motopsycho87]

That's what I had before hand, I have a set of 0.45's and 0.48's. I might go back, it just felt a little bit too soft on the road (I use my bike for riding to work sometimes, enduro, and SM when I can be bothered to change the wheels over)

Braking bumps will be way too fast for clickers to make a difference. It's just an orifice with a needle and that will limit.

Ive still got an issue with headshake ?

I really can fault the suspension now, it only bottoms on the biggest of hits, the bike turns on a pin, traks over the slipperiest of roots and cambers, but every now and then it scares the bejesus out of me with a wicked headshake. It lasts a few seconds but is feeling as if it could get out of hand, I have springs to my weight, ballpark sag numbers too.

Anyone else had this and whats the cure

http://www.dirt-bike-secrets.com/headshake.html - apparently a balance problem!

I set my sag up yesterday.

Front
Static - 35
Race - 70

Rear
Static - 35
Race - 100

Fingers crossed I can sort it out on the clickers now!

ive set mine up with rear at 38static/100 race.backed off my pfp 1 turn on front and ended with 53mm race on front.(76kg rider 13 ec200r).what should the front actually be for the 48 zokes with pfp?ive heard both 55 and 65-70mm recommended,rear was at 85mm race as stock,suggesting im just on the light side for this spring.front was stock at 48mm race now 53mm.what do u guys think?32:1 could your front rim be damaged or out of balance?steering head bearings too loose/tight?rear wheel alignment?bad tyre?

http://racetech.com/page/id/30#3 racetech are the gods of dirt bike suspension. So I've gone with these sag figures.

http://www.mxonly.ca/index.php/suspe...pack-motocross is a good site for adjusting clickers

[barossi73]

thanks,so looks like I need to drop preload more at front,either by pfp or internally?question-can the internal adjustment be made without removing forks and disassembling?i understand theres a clip with 4 positions just not sure how much involved to get in there...can I just remove cap and there it is or do I need special tools?

[motopsycho87]

No idea what PFP is? My bike is a 2006 and only adjustable by removing fork, spring, and then spacer.

Barossi, you can download the Marzocchi manual from their site. To access the preload you need to undo the fork cap, drain the oil from the other, and then undo the 19mm nut on the bottom and remove the cartridge. You can then press the spring perch down to reveal the circlip and groves and made adjustment, but from memory they only had around 5mm preload on them and moving it to the next slot would make that 0mm and you may find the spring rattling at full extension.

Also, the circlip can have sharp edges which can cause issues when removing/putting the spring seat back against it. This is what happened to my Marzocchi 48mms and destroyed the coating on the cartridges when the aluminium made its way into the cartridge. Take special care to dress the circlip ends if doing this.

I haven't measured my sag at the front, but I would guess I work more within the 55-60mm range. I prefer a firmer front end that can take some big hits. I'd try backing off the PFP a little before going internal. Also, the 48mm with PFP chew the oil out quickly - usually 25hrs and the forks are noticably performing less than they should.

ok thanks,the caps stay on for now then!
