Bell Crank or Hex Bar?

So @mikedjames and myself discovered at TE that my CB Performance hex bar linkage is worn. Having one person operate it, where the cable attaches while the other focus on the ball joints and the linkage ends, you can see vertical movement that shouldn't happen.

I got home but it still pops when downshifting

On Sunday, it didn't matter how hard we tried we could get the linkage to adjust so both carbs closed or opened correctly in sync, even by eye, let alone with a meter, it just wouldn't happen. I don't think I stand a chance of having sync'd carbs with this worn linkage.

So I have good experiences with CSP stuff, should I go for another hex bar, or the bell Crank style one? It's a type 4. What are your experiences/thoughts?

Thanks.

 

U can buy the joints and threaded parts eBay sell them mine popped and banged on down shift when carbs was loose

Are they CB parts, or just generic stuff, Si? Just wondering what to search for?

Type in " carb linkage rod" into eBay and get the size u need mate

I'll give that a go, thanks, Si.

 

Which bits are worn? If it's the joints then they are called rod ends and come in metric and imperial sizes. I usually get them from McGill Motorsport

 

Ah, right. I get loads of these, https://www.ebay.co.uk/itm/293198865535

Is that what you're thinking of?

What I need is the ball joints on the end of the horizontal hex bar itself.

 

Oh right I see not seen it wear there but only trouble is cab is in the us it's well dear try euro carb

It's not the rose bearings, it's the ball and socket on the bar itself, if that helps?

 

The bit that's got the spring tension not sure where to get that

Yep, that bit.

Might be this, but it could be the bar itself.

Found the CB part on Eurocarb, CB3360

If I need a new bar it's £42, roughly for a bar and two new balls.

A new CSP hex bar linkage is going to £200+

 

I guess so. I think mine are ok. Are you needing new ones?

 

Sorry ignore that was thinking of empi linkage Mate

I go for bell crank everytime these days. They are so much easier to balance, and stay balanced.

 

Hi ya, glad to hear you got back ok, despite the popping! You aren’t f pantos for nothing

I love the csp centre mount on my bug. Not sure if the vintage speed one fits type 4, but that looks good too. So many less parts for wear and additional movement. Need the additional spring that isn’t included though as the carb springs aren’t enough.

Do CSP do a type 4 bell crank? I thought they did, now I can't seem to find it! Must admit I have bell crank on the Bug and I agree, much easier to set up; far less complex geometry to worry about.

 

Oh yes, can only find with Porsche fan type 4.
