Title: rejetting an 06 afterthoughts
Post by: plusultra on August 19, 2006, 03:59:55 PM
Ok, so I'm finally done with the rejet.  This post is mainly for newbs like me who are thinking into ripping into the carbs.  First thing is rejetting made the bike run a LOT better.  It feels like a different bike.  If u decide to do this, take my advice:

The hoses, those damn hoses.  Make sure u mark them all and take pics with your cell phone, draw a diagram, or something that will help u later.  This is probably the most important part as when i put my bike together it ran like crap b/c of a tini little vacuum hose. A quick search will tell u how many ppl f'd this step up.  the 06 fuel petcock has a gray hose (only one not braided)  that runs from the LEFT of the bike all the way to the RIGHT.  Counterintuitive and seemingly trivial, yes.  Totally necessary, yes.  So make really sure u know where everything goes.

Second, the screws in the carbs are flimsy.  U will have to use a screw extractor or EZout.  That means drilling the screw out and it's a Buddha Loves You but we did it and so can you.  You will have to replace these screws.
Good luck and plan ahead if u decide to do it.  It took me and my friend about 12 hrs to get it right, and it was worth it.

Re-jetting is a miracle. The bike IS completely different. Instant warmup and better response. There is one catch though...

Don't mention it to your insurance company. They don't like that and sometimes charge more for your plan. That goes for pipes as well.

The 06 comes stock with 130's and 17.5's .  Go up one size on each for stock config.   :cheers:

I thought they had 127.5's. The ones I worked on has 127.5's ... not exactly sure that they were 06. Maybe 04, maybe even earlier.
Cool.

The '01 and '02 had 127.5 mains. In '04 they went to 130 mains.

One thing I couldn't figure out how  to do was to shim the needle.  It was fastened, not loose ready to drop when you tip it like the one on the pictures in the tutorial Also it seems to have a spring in the top part of it, so I did not see the need for putting washers.  Yeah, the rejet is awesome, it sounds way better, less like a sewing machine, more like a bike.  and also it pulls throughout the rpm  band. Wow!

peace!   :cheers:

If you should decide to do it in the future, here's the deal; In 2001 they went to a different arrangement to hold the needles in place- it does have a "spring in the top part of it", but that doesn't affect the need for shimming one way or the other- the shims are to control the height.

First, gently take the slide and diaphragm to some place where it's safe- where you won't lose any tiny parts that might go flying. Get a good light and peer down into the slide, and you'll see an off-white little flange- it's the top of a "stopper" that's designed to be gripped with needle-nose pliers. Just grip it and either twist gently or just pull- the "stopper" is retained by a tight o-ring, just friction. The needle may come out with the stopper, or you may need to tip the slide once it's out, but be very careful at this point- there's a tiny washer and a very small spring that will try to excape. Just take the needle out, shim it, drop it back into place (with that one washer on TOP of the circlip/e-clip), and gently return it to the carb.

If you're still a bit lean you may notice a "flat spot" somewhere around 8,000 rpm. The improvement from rejetting is so drastic, you might not notice it at first.

Hey, might just do that... sometime. No thanks required, though, lots and lots of kind people here helped me. Heck, even some of the not-so-kind people helped. ;)

I wouldn't do the shims unless/until you're sure you need to/want to. Every bike is a little different, and if you've found the right combination on the first try, I sure wouldn't fight it.
