What's up guys. I'm new here and just got my first bike. The person I got the bike from told me he dropped the bike on its side and cracked the fairing. Well someone pointed out to me that my front forks leak and that the tire looks pretty close to the radiator. And that he thinks it was damaged from the front.... My question is can someone tell me what the measurement should be? I stood my bike up and had my wife measure as good as she could. It was aboit 2 1/2" from the tire to radiator. does that sound right? There are no fairings on at the moment

Hope the pic shows I don't really know how to post on this forum .


Edit : sorry posting from my phone. Here's a link to the pic in photobucket

I dont think that measurement will really tell you if your forks are damaged or tweaked, but someone else might provide it for you.

I would drop the forks out and check to make sure they are straight.
Inspect the fork holder upper/lower (Triple clamp)and frame for visible damage.

before replacing the fork seals try this little tool


if they leak bad, zip tie a small rag to keep brake fluid off your brake pads until you can fix
FYI

2.5" sounds fucking close.

When looking at the bike side-on
Take a string, hold it in the middle of the fork diameter and the triple clamp, then run it down the fork to the middle of the axle. This will give you a rough idea of if the fork is bent or not. It looks a little bent in the picture.

Also, that bike was not dropped, it was crashed. You have scrapes along the clutch cover that only happen when the bike is sliding forwards on its side. That's a pretty wicked dent in the tank, and the bottom of the lower triple clamp looks kind of gouged up.

Also, the bike is now 12 years old and has likely never had the forks serviced. It's time for new oil regardless of if you can get the seals to come back using Blackdog's posted method. I'd bite the bullet and pull them apart and check for straightness... but I don't have a good feeling.

Yes sir. I was just told the same thing from my local shop. They said it looks like the oil seals are wearing out. Everyrhing else looked pretty good.Dont know how hard it is to replace them but they were only 18 bucks so I got em lol. They also recommended an oil change so gonna do that also. I've read online that you can use regular motor oil. They said at the shop you shouldn't do that. I should use motorcycle oil..Anyone know why ?

The 0w-30 and 5w-30 car oils could make a motorcycle wet (oiled) clutch slip too much.

The 10w-40 and 20w-50 car oils are probably OK, if they are not shown as energy (or resource) conserving on the label; but they might shear faster to a thinner oil from the motorcycle transmission gears.

Motorcycle oils generally last longer and cost more.

A good article about motorcycle oils is linked below:

Cars as a general rule have a dry clutch. Your bike has a wet clutch that is lubricated by the engine oil.

Car oil generally has "friction modifiers" such as teflon that can cause your clutch to slip. Some people talk about putting in diesel, or high performance car oil. After talking to one of the Esso techs, I just stick with motorcycle oil. I like the Maxima stuff and run it in my track bike, and my wife's SV. The KTM gets different...

Whatever oil you decide to buy, stick with that brand and weight (10w40) as different oils have different additive packages that can counteract each other, or combine in weird ways. For example, too much antifroth additive will actually make the oil frothier.

As far as replacing your seals, you need to do:
Dust Seal
Oil Seal
Inner bushing
Outer bushing

And will need a couple of special tools:
Damping Rod holder
Spring Compressor
Seal driver
all spring to mind.

It's about a 2-3 hour job and shops charge accordingly. You'll also need fork oil - likely 5 or 10 weight.
