Default Clutch adjustment

Recently a buddy of mine bought his son a KX 65. In trying to teach him how to ride it he noticed that the clutch doesnt engage (start pulling) until the lever is mm's from being fully released. My YZ clutch is the same way but Ive never minded, but for teaching a young boy how to ride gears for the first time, I could see where itd be difficult. He'd like for the bike to start pulling sooner in the clutch release...any ideas as to where/how that adjustment is made?

It doesnt sound like the bike has much wear on it, and that the clutch should be pretty fresh. I would loosen the adjustment down to where it still releases enough to get it in gear without jumping is all, and see if it stays. You can take a propane torch and bend the lever to a more suitable curve too. They seem to break a little easier after that treatment, so get extras.

There should be .5mm freeplay in the clutch lever. A trick is to put a nickel between the lever and perch. This should be your freeplay. Heating and bending your levers is not recommended.

All together now....."Get a manual."

sage advice i am sure. it is also time well spent to read the post and what the question really is, but i am sure George appreciates the advice on the manual.

We had the same problem with Corbins 65 and we ended up buying the combo ASV's (just bought another set for his 85 )a little pricey @ $70, but worth the investment, really good adjustment options.
Tell your friend to check out the ones here on ATM as well ~ They may have the same design ( did'nt realize we sold em till after a bought Sorry Woody

The factory doesn't build a clutch system so the buyer needs to use a different/modified lever.

If the clutch is starting to grab later in the clutch lever release, it seems there is too much play in the cable/lever adjustment.

Yeah you young punk, get a manual. then lern how to read it. By the way, the clutch is on the left side of the handlebars!

I've been in your situation recently. I recommend:

1. swapping the jets out for new ones
2. stretching the fingers out on the child in question
3. take the bike to Americus Honda - they'll know what to do
4. making an adjustment on the lower portion of the clutch cable so that the clutch engages sooner
5. make the kid always push start the bike so it's a non-issue
6. get a 4 stroke
7. switch to a 2 stroke
8. buy a $300 hydraulic clutch
9. sell the bike
10. teach the kid to use the lawnmower instead
11. take up stamp collecting
12. get a manual

I'll ask my 2nd period shop teacher. He used to race mopeds back in the 80's
I'm sure he'll have an answer.

By the way George, did your friend get the clutch working the WAY he wants for his child?

Speaking of children
Brapp, as you mature in this sport you will see lots of things done for certain situations that the factory did not address. Seems they just can't tailor make things for us all.

Manuel, I dont need no stinkin manuel. I ll just get on this website and ask y'all to think for me. Whose got time to go thru a bunch of writing and confuzing pictures when all I have to do is put up a post on here. You see, this way I can sit back and wait while y'all look up the answers for me. No cents in both of us waisting our time, right..sounds silly to me if you ask me. Anyways, could you guys find a diaphragm of the cable routeing for me so I can see how it routes from the handle bars to the motor? One last thing...wouldnt the nickle fall off when you ride?? What good would it be once it falls off? Should I maybe use some duck tape to hold it in their? Thanks again guys for all your help.

Well hopefully I can get an answer to the nickle question from brapp. I dont wanna look stupid when I tell my friend how to fix his problem. Im real precise about getting good infermation before I do something, something my dad has installed in me.

Default Re: Clutch adjustment

And you come here asking for advice? ;-) I usually set my own clutches to take out the slack where the angle at the pivot bolt and the cable form a 90 degree angle, it makes them easier to pull and is probably more like 3 nickles, since I do it by eye and not spare change. If the basket is in good shape, as the 65 you mention likely is, the young rider can probably still get a good enough release to get into gear without grinding. That is all that is necessary to make any of the mechanical parts happy. If the basket is more worn, springs are unevenly tensioned or worn etc, then it may not release enough to get into gear easily. Some of the dog leg levers you can buy cheaply may be the answer, as is the heating (that the resident "factory" man doesn't suggest). I would still tell him to just loosen the adjustment if he hasn't tried that already. He can probably take up the slack a little bit each two weeks until it is back to where it is now and his rider probably will be used to it by then.
