Suspension DIY service

19 posts in this topic

I'm satisfied with my stock suspension and would like to service it myself. What special tools will I need for the forks and is it worth doing the shock myself since it requires nitrogen? Also, are there any tricks to doing it right and what oil(s) would you recommend?

The first half of your question depends on what year your bike is. As to the shock, I just drop mine off and pay the $45 I get charged for it.

My bike is a 2006 and I weigh about 160 lbs. Does the $45 include service or just nitro?

Oil change and recharge with new seals (less the cost of the seals).
would that be the same for the front forks?

How did you learn to do it and do you think I could do it myself? I have done rebuilds on a two stroke put jets in repacked steering stem and basic maintence on bikes. I was always skidish on the forks,all I want to learn is changing the oil in the forks when its due for a change and maybe replacing the dust seals if worn.

It is really not hard at all. Find a time when you are not rushed and follow the Yamaha service manual that came with you bike. The manual covers it pretty well. If you get into it and have some trouble TT will help you out.

Gray - Just wondering, since 48mm is just under 2'' could a person use 2'' ID pvc as a seal driver? :thumbsup: Just wondering because that seal driver is almost $60 and pvc would be about $5.

People have done that, but the real deal works much better. Rocky Mountain has a seal driver for less, I believe.

Well!... can you change the fork oil in the tube without having to take the forks off?>>>>>Can you just siphon the amount of oil you need out or squirt the amount you need in to adjust the level of oil?

You could change the oil without removing the forks, but not by siphoning.

You would need to remove the handlebars and then the "fork caps", which are actually the damper cartridge (be sure you loosen the top triple clamp bolts). Then compress the forks about 1-2" and remove the adjuster assembly from the bottom of the fork leg. The outer tube oil will drain from there.

If you also want to change the oil in the damper cartridge, continue by removing the adjuster from the damper rod, and service the cartridge per the manual.

DO NOT allow the forks to extend beyond the point you compressed them to while the damper is out or seal damage may very well occur. And having said that, let me say that I don't see this as being very much easier than pulling the fork, anyway, and I frankly don't recommend it. But yes, it could be done.

long time no see everybody!!

I've been at academy, not able to ride. but now there is an end in site, and I want to prep my bike. Grey, where is this place you take your rear shock to get serviced? I don't really like my local shop, nor do I like their prices.

thanks.

Take it to the nearest good suspension shop to where you are. If you just want it serviced, they can all do that, and they don't charge "that much". In my case, it's Precision Concepts in El Cajon, CA.

5 minutes in a mud race could make a seal leak. Mine have before and i used a piece of film to clean the seal out. It hasn't leaked since. Maybe there is a rock ding on that particular fork tube but i don't see Precision concepts missing something like that when there completely going through the forks. Thats the first thing i look for.

Yep, that's him. Their specialty is really the XR650 and Baja/desert setups, and you'll see a lot of his stuff on Big Red around SoCal.
