Try this before you decide to replace the seals.Get some camera film negative.Cut the notches off the side with scissors and cut one end of it about 45%.This should leave you with a piece about 4 inches long.Now slide the pointed end up and into the fork seal.With a sawing motion,slowly work your way around the seal.You may 'feel' some tiny bits of grit.Pull it out ,wipe clean and do it again.It may take 3-4 times to get the seal clean.Do this slowly and you will get to feel where the grit is.The grit makes it leak.Unless you have a puddle of oil on the ground,don't worry about the oil level.This will work more often then not and save you heaps of bucks.We always take some if we go for a weekend ride.Hope this helps

How do I put front wheel on without making the forks lock up it keeps doing that when I put it on my02 cr250

Putting uneven loading on the forks(twist) may cause binding and harsh action but I haven't heard of them locking up. Try the following order of installation. position the wheel and slide in the axel. Tighten the axel, leaving the pinch nuts loose. Spin the tire and stop it a few times using the front brake. Tighten the pinch nuts. Put bike on the ground and see if forks still bind. If they do then loosen the pinch bolts, lock the front brake and try to compress the forks. This should align the forks. Tighten the pinch bolts. Check forks again. If you still have problems someting is wrong like bent fork tube or slider, misaligned triple clamp, maybe a bent axel.You might take off the fork tubes and push on them seperately to make sure they feel ok. Then do the install checking the forks at each step to find the place where binding starts. Good luck.

I have a 2002 Yamaha R1 that i recently put new forks on due to it being laid over. The frame as well as the new forks are straight but the front tire is hitting my headers.

front end needs to be adjusted...meaning you need to adjust the height of your bike from the adjusters located at your triple tree....if not have those forks inspected for defaults like leaking fluid....hope this was helpful.

If feels like a pogo stick sometimes and also wants the front end to wash out too and on the front forks i have a oil leak

Your front fork seal are bad and need to be replaced.
When you loose fork oil, your loosing suspension dampening and only riding on the springs.(POGO)

Replace both front fork seals and dust caps, and put same amount of fork fluid in both forks.

I bought my seals and caps for $30 on ebay, and then took my forks off my bike and took them to a shop and they charged me $75 to do the job.

You can take them the whole bike and they will charge $100 - $150 including parts to do the job.

Can i stiffen up the tension in my front forks on my mgx dxr?

Sorry to inform you, but there is no adjustments available for the forks that come with your bike. Adjustable forks (just the fork) start in around $250-.

On the positive side since there is not adjustment capability the fork does not need regular servicing like the adjustable forks.

My front forks on my 94 rm125 compress but won't

Most likely cause is worn bushings in the forks. This will require total disassembly and replacing the bushings along with the fluid and seals.

My triple tree bearings nuts are not loose nor are my fork tube clamps. but i still feel like the fron wheel is tracking side to side. do you know what i mean? oh ya checked front axle its tight too.

are the forks leaking oil? is there air pressure in the forks? Start by draining the forks and putting in the correct ammount of the proper oil, and getting the air pressure right then see how she rides. Other things to check, front wheel bearings, worn triple tree bearings.

I would like to know how to change the front forks on my burman

To remove the forks you need to untighten the screws holding the forks in the yoke, then hit the tops of the forks slightly with a wooden hammer to get them out of the yoke.

Can you straighten torqued front forks on a 2002 Yamaha TTR 125 L

you should be able to saporrt bike so front wheel is off the ground   then take a marker and put lines around where the forks meet the triple trees that hold them in place their should be some allen head bolts that u can loosen on front of the triple clamps  once these are loose you should be able  to move the forks back to strait again in line with the handle bars just line the lines up that u put on them earlier and tighten the allen bolts back up    also  when making the lines  make them from left  to right so marker is touching both fork tube and triple clamp   this is only so you get can keep them the same ride hight as before
