Just a note on the bottom Allen bolts..
I had read somewhere ( I wish I could remember where) after changing my oil that you do not have to remove the Allen Bolts for the oil change on Inverted Forks, that once removed they can be real tough to get started again as it could just spin the bottom cartridge. |

"I put about 4oz of Trans Fluid in my USD forks and they seem to be working fine. I did not remove my forks. Only the top screw cap."
It looks like you have the inverted forks.. Did you drain out any oil before adding the 4 oz? Were your forks sticking before you added atf? Has anyone been successful in draining their fork oil while the forks were on the bike? |

is this 4oz to each side or 4oz total for both? aka 2oz left and 2oz right?
You did this on the ground? or on a stand? Just curious, never had forks apart in my life.

Measured 4oz and poured into the each leg on the ground. Maybe could have had more but I didn't want to risk blowing any of the seals.

USD Fork cap removal
I tried to remove the fork caps to add some 5w fluid but they would only loosen up but not come out (forks still on bike per fb250). I did some light tapping but that didn't help. Do you need to loosen the bottom allen bolts or what is the method?
The fork caps easily threaded back in and I'm trying to avoid another big project for now. Thanks! |

Mine on the 07 GY-5 are pretty plush but It does feel like it might have minor “sticky/notchy†feel. I read people are adding a little ATF fluid to the tube. Is ATF fluid safe on the seals used in forks? Is it the same as shock oil or something? If it gets worse I might look into it but for now it’s not a problem.

ATF is about $2 a quart, but if it is safe to use? Fork oil comes in different weights and any motorcycle shop should carry it.

ive heard from more places then this one, that ATF can be mixed with the fork oil or even replace it. i put 4oz in each leg of mine and its not as notchy, i actually used some old ATF+3 i had in the garage
ATF is a little thicker, prob about 15wt. As for the fork seals, automatic trannys have much more demanding seals in them. If ATF doesnt harm the main and rear seals on a tranny, I doubt it will harm your fork seals. |

The ATF is an old school performance mod that I read about in one of my old Suzuki GS750/850 manuals. I did it back then to my GS850 and had no problems. And now on my Roketa with no problems. I may need to add a few more oz. because I still get a sticky feeling every now and again, but nothing like it was. I just didn't want to put too much and have issues with my seals.

Here is another idea on sticky forks - fork binding.
Luckily, the repair is free. Put your bike on a stand so that it is balanced well, and the front wheel is in light contact with the ground. Loosen the top triple clamp stem bolt, the upper and lower triple clamp bolts, and the front axle. When I say loosen, I mean only to the point that the parts can move, if a bit sticky. Definitely not falling apart! Depending on how your front axle mounts, you may have left and right axle clamps, or the axle may thread into one fork leg and have an axle clamp on the other. Start retightening with the lower triple clamp pinch bolts, making sure the fork tubes are even. Then snug, but not tighten, the stem nut. Tighten the upper TC pinch bolts, then tighten the stem nut. Finally, tighten the front axle. For the threaded axle type, tighten the axle bolt first, then the axle clamp. For twin axle clamps tighten one side then the other. Always tighten an axle clamp starting at the top fully tight, then tighten the bottom. The whole point of this exercise to to ensure that the forks are relaxed, then aligned and tightened, and that the axle does not draw the fork bottoms together. |
