So, this comes form the KLR forums it's called the $.22 mod, (well at least some of it).
Let's start form the beginning.
My boy bought a '93 750 (that's why I'm on this site!
It has these God awful loud straight pipes, (did I really think that was cool when I was 17)???
Any banna, it has a stumble right off pilot on the needle, (lean).
So, being the constant tinker, I ripped the tank off.
"There is NO way I'm ripping these carbs off just to get at the needle"!
So, being a mechanic/barbarian........
If you slide a hammer handle at the end of the air box and wedge the air box up get a, 3/4" lenght #2 philips tip, (I ground the top off one to make it fit), 1/4" open end wrench, you can get at the screws that hold the carb top on.
Then you can jjjjjuuuuusssssttt get the needle out. (be carful of that dia. it's flimsy and is expensiveto replace)!!!!!!!!!!!
you'll see the stock needle is non-adjustable.
This is where the KLR mod comes in.
Go to Lowes (or???????????) and get some #4 washers
Slip the washer on the needle and that'll raise the needle up 1 position as though it were a clipped needle.
I have 2 on my KLR and it works good.
One did Gary's bike right!
Buttoned it up, (you can get at the back screw on the clutch side carb with a LONG screw driver. Put some grease on the tip to hole the screw).
Took maybe 1 hour, counting the 15 minues of thinking time to do it!
Just thought I'd pass that on.
Give me enough time and I'll break it good!
