Adjusting Needle On Mikuni PAIN IN THE ARSE!
« on: May 03, 2013, 03:00:56 pm »
I have been running a Kehein PJ carb for many many years, it ran great but I am switching back to a modified Stock Mikuni.

I am having Post Tramatic Stress Flashbacks of fighting with the carb spring trying to adjust the needle.  The PJ was much easier.   What is the easiest way to put spring/throttle cable back together after adjusting needle.

Make sure that the throttle cable is free to float under the gas tank and is not zip tied to the frame tube.

It just takes some practice.  After doing it a thousand times or so you will be able to do it with one hand and your eyes closed.

I press the spring all the way up and pin my thumb against the cable where it comes out holding it and the spring in place, slide the plastic retainer on and then work the tip of the cable into the groove inside the slide. It's not that bad once you get the hang of it.

I've used a set of needle nosed vice grips with a piece of soft poly hose on one of the jaws. Arthritic hands make it a really painful task without the grips.

-Compress spring
-Use safety wire to hold it
-Fiddle with the needle and other crap in there
-Put everything back in place
-Cut safety wire and let spring do what comes naturally

I've used a small hemostat to keep the spring compressed and out of the way. It also works good for removing and replacing the plastic retainer. You can hold the spring with one hand and place the retainer with the hemostat. Been doing it that way since sometime around 1990.

Good tips...I have some nerve damage in hands so I dont have the fine motor skills/finger dexterity most peop[le have.  I know a hemostat is some type of medical clamp---does anyone have a picture of one and where can I buy some.  Thanks for the tips guys.

Motorgeek---hope I never ever ever have to do so many that i can do it one handed with eyes closed  :)

Hemostat should be able to get one at your local pharmacy if you can't find it ask the pharmacist.

 C:-)  Yes, I can hear the conversation with the pharmacist....... Yes, yes see these are for my atv...see sir, the hemostats are to ease jetting, the surgical tubing is my fuel line, and ah--uh, the bunson burner is to heat parts for bearing removal, and those syringes and needles are to inject grease into my bearings------uh, honest sir.

No it's called drug paraphernalia and if you're in high school using a pair of them to crimp ignition wires together, YOU GET A WEEK OF DETENTION.
They still aren't sure how someone managed to do a burnout 3ft up the back wall at that school, it happened some time in the night and there were no witnesses.
I have a sneaking suspicion that someone was using an Atlas II transfer case with dual sticks.

I use those to pinch off my powerjet lines so I can purge out the alky. And quite complaining how hard it is or a PITA. Grab the spring with your fingertips slide it back and pinch the cable while simotaneaously holding the spring back. Slide the cable out the slide and adjust the clip. That's all about wrenching on your own stuff. Hate to hear about you changing your clutch. Lol.

But seriously its not that hard.

It is less of a fight on the keihin PJ.  The issue is with nerve damage in my hands I have fumble fingers or feel like Im all thumbs, so i am sure somme of you have found simplified ways of doing things..like the hemostats....that will help.....right now i am fighting with swing arm removal of an old rusted 98 polaris explorer---those have been beat up by the whole family and still keep ticking.
