I like the triad for one main reason that I can see right off the bat...see how the link arm is almost straight 90 degrees to the carb throttle shaft. That gives you no side loading on the carb throttle shaft.
What I don't like is it looks a bit flimsy.

Yours looks good Aaron, but the 90 degrees to the throttle shaft is very important to making it smooth and to stop premature wear of the shaft bearings.

(IMG:style_emoticons/default/confused24.gif) flimsy? Didn't apear to be when I had one. Very solid actually.

Aaron's system looks very nice and cost effective (IMG:style_emoticons/default/beerchug.gif)

I said "looks" I can't tell the metal thickness from the pic.
Why I'd be saying that is it does look a lot like the el-cheapo Type 1 linkage at first glance.

Mark,

Are you suggesting that the drop links should be vertical or as colinear as possible with the carb shafts? The position can be adjusted very easy. (they have allen set screws to set the distance from the carb)

I might be min-interpreting what you are asking about.

Kevin,
So you deal with play (up to a half inch) when the motor isnt fully warmed up or super warm?
Swapping out springs would be easy.... but I like to account for the play, versus letting it flop around until warm.

The Bugpack bell crank works better than the CB cross bar. You have to modify it to remove the slop, but it is a better choice. I have had both and now I only use the Bugpack bell crank setup.

Looks like you did a good job with your mods. I hope it will work right longer than the original design.

....


Yes, the droplinks should not push in/out on the end of the throttle shaft.
Think of setting the endplay on a crank, you don't want it push/pulling it in that way as it causes wear.

This is one of the reasons I also like the bellcrank type, BTW I make my own.

Ahh, The arms are too long is what you are saying... so it is putting a load in the direction of the shaft. Got it...

Look at the triad again, As it goes through the travel, it will put a side load on the shaft also.....

Bugpac has several linkage products. Which one are you refering to? I also have a 2.0 with dual Webbers and am looking for a better allignment or linkage system.
