CV Carb mod to replace plastic washers, which locate under needle circlip that wear out.

[CockneyRick]

I'll have another set if you got owt left. Might as well bang em in the 34's i have. 

Wondering if they'd work in the EFE &GS CV's i have??? 

[jonny1bump]

Rick they may not fit the the 34's and they might not have the step, check with one of the washers you have first.

I'm after a set of 34 carbs but have already made up the spacers as per drawing. If the 34's are different will make up a set for them once I get them!

[fab]

are these still being made, as I would like 2 sets please.

[jonny1bump]

Think have couple sets at my mates down south. I can ask.

[Enduroace]

Since I want to set up my carbs I fist need to get them upo to spec.

This modification is on my to-do list.

 

But I have to ask, why not drill the slide so it has a flat bottom?

Fil the bottom up with a 2mm spacer and the needle sits straight.

Best regards,

I think that would work as well, if you can make 100% sure that all the slide holes are drilled the same depth.

By the way welcome back Minipower

How do you propose to drill slide accurately.

You need to be careful to do this and to advise peeps on here to do that I feel is tad dangerous.

1. You need to clamp slide well, and clock it up square,  it's only plastic remember.

2. You would have use very sharp flat bottom drill, or end mill, which most on here will not have.

3. You need to use mill really so you can control depth accurately too.

4. Any variation between slides will alter carb settings on very sensitive 40 mm carbs.

Or use a CNC spacer which all same thickness and drop straight in.

Complete no brainer really, I personally would not risk scrapping a slide if your not careful but you certainly should not suggest this to peeps on here who listen to our advice and take it verbatim.

When drilling plastic it can bite hard and pull itself into drill especially if someone decides to use a twist drill.

[minipower]

Instead of drilling the slide. Why not use a shim to create a flat bottom inside the slide? The original plastic spacer can then still be used. 

When my I have my carbs parts I will see if the above can be done. 

I am just trying to fine a simple solution. Not everyone knows someone with a milling machine 

[jonny1bump]

A shim won't hold needles square.

The original plastic spacers would still rotate and wear out with that idea.

Your right about mill and to be fair as my mill is manual I sweet talked a friend who has cnc  to make loads at real cheap rate to help the members of this forum. I'm sure we got some left, I would just need to deburr which won't take long.

Initial pricing I have is roughly 25 a set but this is 4 off will reduce more peeps that won't them to cover set up cost.

@jonny1bump yeah they have landed and look real good. On another note, how are you getting on with stripping the gsxr1100/1000 yokes off your bike ? cheers bud.

[Wagola]

@jonny1bumpnot sure why it didn't work first time?

[Jaydee]

@jonny1bumpput me down for a set. Have some 40's here. The needles were well worn (understatement) along with the seats.  Dynojet are replacing the needles on exchange for old ones so this sorts out buying new seats for them as well as being an upgrade. Let me know how to sort out payment and p&p. Thanks.
