Needle Shims

[Bazza]

Ok, here I go, I am begging for a favour here. I need to get a hold of some needle shims, and they are not available anywhere near me, as all the Radio Shack franchises have been bought out by circuit city.

Can anyone help me out? I am looking for 20 of the buggers.

I will gladly send cash!

I mailed all my extra to 123 , I'll run to Radio Shack and see if they have any more.

Radio Shack carrys them still, I just bought a bag of assorteds on Saturday. 3 dollars and change for the bag. They still provide size that fits in the pack. However I dont think there is as many of the size you need in one pack, may have to get a couple.

Hey Chupacabra.....I would owe you big time my friend!

radio shack U.S. still has them   not in Canada though

i have 4 left
i used 2 in each carb (scorpion bolt on) and it runs great now, in fact it may be a tad rich in the mid range but not enough to take 1 out.

I took out the snorkle, made a differance for me. 3 and 3/4 turns out on the screws. RS 3 slip on and 25 mm off the springs.

I still have some left Bazza I'll send you what I have, if we all give you some you'll have 20 in no time. PM us your mailing address. UP here in Canada Radio Shack's been totally bought out. Now a company called "The Source" owns it in Ontario.(Whatever the f*ck the "source" is, dumb name)

Hi Rider....

A little story here...

I actually have an Ivan's jet kit installed on mine which works very well on the bike, but reduced mileage considerably. I used to get 51 mpg now I get 36. (Keep in mind I am talking Imperial MPG)

The other day I rode my buddies B-12 which we installed Dales stage one kit in his bike and he removed it due to fuel consumption. (Well we modified it, putting the stock mains back in, closing up the airbox and shimming the needles with 3 shims). I have to tell you his bike all around is more fun to ride, with the exception of the brutal mid range power mine has as a comparison. (Ivan's kit obtains this with his self made tapered needles) Also, when you do any airbox mods to the B-12, you seriously affect low range power by reducing restriction that is needed in the airbox at very low rpm.

Yes, a jet kit gets you more peak HP, but I am convinced with both Ivan's & Dales kits, that it robs you of low down city riding fun.

But as most of my riding is done on long highway trips & short city jaunts, I think I find the almost stock form much more fun to ride. There has been a huge outrage this summer in my town regarding aftermarket pipes, and I am anticipating that sometime down the road, I will be forced to loose my Yoshi TRS race pipe.

Oh yes, and Gasoline hit $4.68 a US gallon here this summer.

Ok, I went to Radio Shack and picked some up for you. shoot me a place to mail them too.  
I haven't counted them yet, and the package was opened! I can't see you needing five per needle.
I can't remember what size to use, may just mail the whole bag (5 sizes) seeing theres a shortage of washers up there.  

[DaveG]

it would be the smallest ones.

note that rider and i are CANADIAN
you can talk litres and beaver bucks to us.

Actually the second smallest in the pack which equates to #2 regular shims. Hey bazza do you want me to send you the 107.5 mains if I'm not using them this week in the kit? It might be a happy medium, that's 2 sizes down from your 112.5's. You could close up some of the airbox holes and see what happens.

I'm going to check to see if my mechanic did indeed only cut a 1" hole for me. If so he may have invariably have done me a favour as I can drop some shims and gain some fuel economy. Remember the shims in the Holeshot kit are little smaller than half the thickness of the radio shack shims. I was fine with one shim and snorkle in which is about 2.5 holeshot shims. The holeshot shims just give you a better metering. I'll try and send these this week as I'm still fine tuning and don't want to be short myself.   I can't seeing you using more than 2 shims per needle of the radio shack jobbies.


Holeshot shims .010 (.25mm)
Radio shack shims .022 (.5mm) (average)

Just as a followup I just did a plug check and #4 is completely black so I'm going to take a shim off that cylinder and see what happens. Dale said in his kit that this may occur and taking off a shim just on that cylinder may help.

Chupacabra & Rider....

I owe you guys big time!

Cupacabra....check your in box, I sent you an E mail with my address. Let me know what I owe you!

Rider.

Your #4 plug fouling Dilema is the same thing that happened to my buddies bike & we did take care of it by reducing a shim. Man that is odd that it would happen to two bikes in a row. As for your mechanic drilling too small a hole in the airbox, I would recomend just punching another 1/2 diameter hole in the top of the airbox near your big hole. Location is not that important.

[rider123]

YOu know what bazza that may be a better idea than taking out the airbox and getting hacksaw's and such. I wonder if even 2 1/4" holes would do as I have a 1/4 inch bit at home. Let me see bazza if I can fix this bike without having to use the 107.5's if not than I'll send them to you as well as the shims so you can experiment. I'm sure dropping the mains 2 sizes and covering up say 1/4 to half the holes is going to help you.

[chupacabra]

Ok I got 20 shims , I just need to post them.
I'd start with two on each needle and then drop to one.
I bet one each will be the best all round, just a guess.

[DaveG]

two rs shims is woking great for me
no airbox mods just scorpion bolton

plug check shows just a little rich but not enough to be any problem
