New Rider/Old Bike

[Florida 393]

I would look at the actuator arm for wallowing out on its mounting hole, or the actuator shaft being worn where the arm mounts. the cable can stretch a fair amount but 3/8" is a lot (not unheard of though.)

I would pull the clutch basket and look at the shaft and seal since you are there but they will not have anything to do with the cable free play. Since the bike has a few years on it checking the seal and crank end will be a good thing to inspect while you are in there.

Let me know what you find and if the new clutch cable does the trick.

The new Yamaha cable was about 3/4" shorter, and much better construction and thicker cable than what was on there. The dealer recommended I rough up the clutch steels a bit w/scotchbrite or emery cloth before reinstalling. Is this a good idea?? I can think of pros and cons for this.

BTW, the springs, steels and friction discs are within spec for thickness, and the actuator arm and hole looked OK.

Will pull the clutch basket tomorrow AM then put it back together.

Thanks!

I think you licked the problem with the new cable. As to roughing up the steel plates, I have not done this or heard of it before.I would hate to recommend something I am not ffamiliar with. You should get Eric Gorr's book on performance tuning and maintenance for dirt bikes. it is invaluable for doing your own work. John and I have it, ad do many members here and throught out the dirt bike community. It answers a multitude of questions for the do-it yourselfer.

Thanks for the Eric Gorr tip! On his website it answered my oil fill concern. He said "The reason for the great discrepancy in the oil volume, is that the oil runs directly from the filler hole to the level hole. The oil flows along the inside of the clutch cover and out the level hole. The level hole is designed for quick level checking. Also the oil backs up in the clutch cover before it fills the tranny. Its best to wait about twenty minutes before you try to check the oil level. I just fill the tranny with the prescribed measured volume". That tip might have saved me a ton of money right there had I underfilled it by just calling it quits after the oil came out the plug.

Am going to order his book, and will be riding again soon.

Thanks!!!

Book mark the site and buy the book. I got one a year ago and it is a really handy reference. Combined with my owners manual from Yamaha it can lick most any problem. Tryce highly recommendd Eric's site and book to me and that is about all I need to trust something and I am really picky about our bikes. (Engineer's Disease )

now, can't you see why we are so addicted?

does it still have the pink seat in '95? or did they change to blue yet? i can't remember, but mine was pink and white when i got it, but since then i have invested in a black CEET gripper seat cover.

Don't you mean "Rockey got my LT to idle"?

So Rockey, can you offer any tips on getting my YZ250 to idle?

[Dell30rb]

Why, Turn it up of course!

That and a correct air screw setting will let your bike idle. I have mine set so that it idles for about 10 seconds and then dies. I think this is about the correct setting for an mx bike.
For a woods bike (or an mx bike that is used for woods) you might want to try to get it to idle for about 20 seconds. I dont know why, but it seems a slightly higher idle would be best for trail use.

Of course!
On your bike, I think the idle control is located on the choke knob. Try turning the choke counterclockwise I think (may be clockwise) until the bike will idle.

BECAUSE YOU DIDNT GET YOUR LT TO IDLE! :

[4strkepwr660R]

Yes I did Mike- You had it idling too high and I had to lower the idle...Kiss my @$$!!!! LOL...No harm taken

[Rockey]

It seems turning the idle screw/choke knob doesn't make any difference, but yes it is moving as it should. I haven't tried the air screw yet, I set it to the factory setting of 1-1/4.

Y'all need to keep in mind that the new 2-sroke MX bikes with the current carbs and ignitions are not really prone to being able to idle if jetted properly for running in the meat of the power band. That is the nature of the beast. They can be made to idle but that is not how they are ported or jetted. The EXC model KTM's and the WR Husqvarnas and the Gas-Gas 2-strokes are the exceptions. However they are not top end runners. the laat of the 500 class pingers like Madman's KX 500 are an exception to the non idle rule. that is one reason I wish the manufacturers would make true 2 stroke open class dirt bikes again. I love 'em !

Bill, you would LOOOOOOOOOOOOOOOOVE the CR500AF from service Honda! And if you don't you can always send it to me!
