HELP! Front forks always leaking

12 posts in this topic

My 04' yz450's front forks have been leaking oil very slowly for a long time now. I have cleaned the seals and have done the camra negative trick 100 times.

After I ride a few laps I come back and see sevreal oil rings left on the lower shaft. By the end of the day they have leaked enough that it looks like oil has dripped off the bottom.

What do I need to do?

I'm 175lbs and I jump I think 40 to 50 feet but it I land on the down slope so it never seems to bootm out.

Just get the forks serviced. The film negative manuever is a trick used to clean out contamination, and shouldn't be considered regular maintenance.

It's soulds like you've lost a considerable amount of fork oil. I'd make getting the forks serviced a high priority. Fork service generally costs me $200, roll-in, roll-out... for a typical dealer.

You need new seals for sure. Check your local dealers, independants and suspension shops for prices. I do seals for $20 per leg plus parts/fluid.

You need to replace the oil seals, dust seals, and the two bushings in your forks. Your bushings are probably worn, If they are that creates a little slop or play between the inner and outer tubes. I would also look into a set of seal savers. I have had real good luck with them, just make sure u roll them up at the car wash and wash them out. :applause:

Hey man Thanks for the help. I'm looking at an exploded veiw of my forks and I see the oil seal and the dust seal but no bushings. If you don't mind, check out this link and tell me were the bushings are that I need to replace.

What are the local shop rates around you. Here they charge about $65 hr. I charge fifty bucks plus parts for both forks or a shock with nitrogen recharge.

Typical shop will charge 1-1/2 to 2hrs labor plus parts.

I just talked to the bike shop.

Adjust engine vales - $125

Replace seals and refill oil - $250

Revalve job - add $150

This seems pretty high to me for suspension work. what do you guys think?

Sounds about right for a shop. Put'em in a box and ship them up. I'll do them for $50 plus parst and turn them around same day.... Cost about $150 with shipping. :applause:

Call your favorite suspension shop and get a quote. I used Race Tech recently to replace my oil, seals and bushings and they did a good job. If you dont' want a revalve then just be sure they understand that you want a basic service and make sure they understand what oil leve you want to run.
