$0.60 Horsepower...Finally put some washers on the needle

[nascarkeith]

I really want to do this mod but don't clearly see where I put the washers....

The poor man's rejetting pictorial mentioned in above posts has some really good pics.

[Skeets]

Thanks, I think I'm going to try this. I bought a High Perfomance KN Air Filter. I also ordered some flush mounts, and a new windscreen. Pics will be shown soon.

I usually average around 48-50 mpg.  I will keep a check on that and see just how much the washers hurt mpg after a few tanks. 

Ha ... my POS nissan makes 44 to the gal. What kinda scam is suzuki running wiht the damn thing ...
On a side note, the rains from H'cane fay - pouring rain in charlotte and the car's color turned from black to charcoal ...  Soon I'd have a white car.
Cool.

Hey nascarkeith......i've got the 05 model that has the same carb as yours. so when i put my needle shims on it is very difficult to get the plug back in its set position. Did you have this problem and what did you do? Plug = tab w/ o-ring and spring.

I used needle nose pliers to get the plug in there.  My fingers are too big.  I lined things up as carefull as I could and then gently pushed in with the pliers.  Then I checked them to make sure they were seated by pushing on them with my finger.  You gotta be careful to line things up when putting them back in the carb or they can shoot out of there.  Or so I've heard not that mine shot out and landed on the workbench 5 feet away or anything.

Yeah mine popped out a couple times. i was gonna put three washers on but i could barely get the two on and push the plug back in.  i might try to use some NN pliers now with three cause im still a bit lean.

This seems like something i can justify spending money on 

I will add in a few washers on my 07 this weekend when i swap out the intake shims. Just to be clear, I need to buy 5mm x 12mm allen bolts to replace the top brass screws that seem to strip so easily? 12mm was the correct fit?

[Danny500]

Now, when doing this mod on a 00' and older are you supposed to use 2 #4 washers on each needle? Or simply 2 #3 washers like on the 01's and up?

I've read a few different things and am still coming up a tad confused.

Also, do you have to re-sync the carbs afterwards? Any adjustment to the mixture screws needed, or would that negate the amount of fuel you're adding at idle?

I dunno... I think I'm missing the theory behind this.

Is it that instead of just moving you're idle up, you're moving the needle up to add more fuel throughout the travel of the throttle slide? Thus making your bike run rich?

Hell, if it helps, I'll do it tomorrow afternoon... I just need to know what washers for an 00' and if I need to re-sync the carbs.

Would like to know this as well.. Def. want to try this mod on a rainy day.

Wow.. how in the world do you guys get these shitty screws off? I am having a hard time getting any of them loose...! 

EDIT: Got all but one.. Need the screw extractor!

[respite]

I had a hard time getting the screws out. Managed to remove three with vice grips, one had to be extracted. I replaced them all with the suggested replacements.

Worked great with two #3 washers after i adjusted the mixture. Much smoother power. Check the other thread on this topic for details.

How did you adjust the mixture?

[nascarkeith]

I didn't resync carbs or adjust mixture.  All I did was add 2 washers.  A little more power but did not make it run much different.  The screws suck.  Glad you guys got them out without too big of an ordeal.

Oh it was quite an ordeal.. went to Walmart to get a screw extractor and they had one set.. this one set was missing 2 out of 5. The best they could do is give me a 10% discount on it.. I said F U and will take care of it tomorrow morning (sisters b/f is bring an extractor).. The #3 washers I bought had a correct outer diameter but the inner diameter was too small so I had to widen them myself. Also, when you put the "plug" back in, how do you know when to stop pushing it in??
Thanks,

Just finished up and went for a ride. One word - SMOOTH..
well maybe two words - AWESOME!

Def. would suggest this to anyone who wants to make their bike a little bit more smoother

What's happenning when you add washers. What is the purpose of the needle. I understand cars pretty well so if there's a part on a car that it compares to that would help.

[jrains89]

apparently you don't know cars that well. the closest thing to a jet on a car, is a jet. cars that have a carburetor or carburetors use them.

Did I ask about a jet? I didn't think so. I asked about the needle. Seeing how you didn't answer my question, its probably safe to assume you can't. So maybe you need to read this topic " http://gstwins.com/gsboard/index.php?topic=43853.0 " as much as I did in order to understand what the needle does. That way, next time someone asks, you might be able to make yourself usefull.

I dont get what size whshers you used..... wth size are #3 washers?

[REAP]

Ok, i worked out the size and did the mod.... I have an 07 GS500f and when i did this, it seemed to restrict the flow of fuel not increase it...

I used 2 washers on each.

Not so sure on this one, if anyone has any reason for this please explain.
