O chit Gas man whats up now?

ok the wife clipped a corner and lowsided her EX250 today. She is fine and yes she was in full gear. The problem was I had to ride it home the steering is slightly off. It landed on the left handle pushing the forks out of alignment. The left fork has been pulled in about a 1/4 of an inch. This is making the wheel turn to the left slightly. So in order to get it home I had to turn it to the right to get the wheel straight. SO the question now.

What would be the best way to straighten out the forks again.

A) take off the front wheel so I can straighten them back out.

B) some other way


So after staring at this for a few I'm not real sure how to handle this one. Open to suggestions....I would prefer to do it at home since it seems only a slight problem.

Can't be sure without seeing it, but it may be as simple as loosening a nut or two and twisting on the handlebars to get it straight. It could also be as bad as a bent fork, in which case you'll need to raise it off the ground to remove and replace the fork(s).

ya the forks themselves look straight. it is more of the left on being pulled in and the right one being pushed out.....not real sure on the solution yet. hopefully I'm not into having to change out the front forks....

One way to check for bent forks...


Take off the wheel and turn the bottom part of the fork, if it doesnt make a complete revolution. You'll know it's bent

good point...I'll check this too.

I don't think they are bent though.

The March, 2004 issue of Cycle World had this same type of incident in their Service section. They said it could just be that the clip-on or handlebar is bent. To see if one or both of the triple clamps is bent, remove the wheel and both forks. One by one, insert each fork tube. Each should slide up into each triple clamp easily. If there is a lot of resistance either the clamp or fork is bent.

The magazine says too check if the fork is bent, rotate it 360 degrees to see if it hangs up in the clamp. Although if the fork is bent, it would seem to me that you rotate it 180 degrees to see. Also, the axle could be bent.

sav, the solution is simple; Make her lowside it on another curb on the opposite side.

Sav... sorry it took me so long... I was gone all weekend. My wife was riding this weekend as well but thankfully didn't wreck.. I can't believe the heart dropping stress you went thru for that! I feel for you.

Bottom line is... you need to pull the entire front end. These guys already told you alot of cool ways to check. You can also check using a flat edge or level on the parts. But I like the more user friendly options stated above.

Once checked as stated above you need to reessemble everything. Sense you have the front end pulled... how old is the little ninja? If it has any countable miles 10,000 or more... grease up the neck bearings. Get the tripples back on and torqued to specs.

Now slide each fork in to the tripples. Make sure you get them in there even. You don't want one higher than the other. When you slide in the first tube... tighten the bottom clamp bolt. Not really really tight. Just enough to hold the tube in place. Now do the same on the other side. that should get the tripples lined up. So torque all four clamps on the tripples to factory specs.

Torqueing to factory specs is important. Especially when dealing with alum. You can get a decent torque wrench at Sears.

Now install the wheel and axle. Grease all that up real good. I just use axle grease... then re-install the brake caliper (which I usually string or wire up somewhere to keep the tension off the brake line)

Here's some pics of the last time I pulled forks on my 9R. I did them for a different reason... but the install is the same.









That's what you do to pull the forks... but if you have to pull the tripple... you need something else under the bike... like so...

appreciate it...Ya I was freaking startled when she went down and I wasn't able to get off the bike quick enough.

but i was relieved when she got up....then next worry was **** she is going to be doubting her self....and not want to ride anymore.....

but that passed quickly after when she got up because she wrecked not be cause she sucked...

she got up took her gloves off and immediatly started checking her bike over. She was mad when I didn't have it back up in shape by sunday so she could ride some more. What was cool was she already knew exactly what she did wrong and started to critque it...

I was so freaking happy about that.


appreciate it between you and crazy250 I think I can get that going.

repts coming.

Yeah that low of miles don't mean nuttin.

Well give your wife major props for wanting to jump right back on the game.

Did the wife go wide and clip the outside curb? I konw my wife sometimes goes wide on her right turns. I'm always telling her to stay in her lane and position. There was this one time... she went a little wide... there was a car... she quickly tucked it in and took the corner.

She said she knew she couldn't apply the brakes... so she tucked it in, twisted the throttle and made the corner... at the time I was behind her and watching this. She did great.

Yea I feel ya...

yea actually she went to tight and hit the curb in a parking lot. I freaked...but she didn't...

Bike is fixed and back up and going as of this morning.

Now i'm going to give her a few more months of learning before I try and go to fix the fairings.....The left side is cracked by the blinker. both blinkers are going to have to be replace...the right side cracked when she dropped it the day before her msf class....

hey thats why I got her a tank..umm...ninja....

I went with Crazy250's website and checkout all of there solutions...

I then loosened all of the bolts holding the front shocks. I also loosened up the front wheel. After doing that I just had to pull the front shocks straight. after eyeballing it I ended up laying a little mirror across them to see if they were straight and I adjusted in till they were. once straight I just tightened the bolts from top to bottom. then took it out for a test ride down the street. it was all good so no complaints....

I appreciate all of you guys help.
