Carb Linkage Mod

So here is the carb set-up with the new throttle linkage position. Now the cable can route down the backbone and pop out in the center of the carbs :)

Just need to shorten the left over throttle shaft on the left side of the left carb. Need to make a shaft seal so it doesn't suck air through the needle bearing supporting the shaft.

I'll shorten up the intake silicone tubes a little, after we get the head back on. Figure we'll go as long as we can to keep that low end grunt where we want it.

Need to make some internal sleeves for the silicone, to match the spigots and throttle bores. it'd be nice not to have steps in the intake tract. As it is, the ID of the silicone obviously fits the OD of the spigots. we'll turn some Delrin (resistant to gasoline) sleeves and press them into the silicone. this will smooth it out a little.

As was from Topham Mikuni. Left side throttle linkage.

Center location


Yummy, accelerator pump. proper 4 stroke stuff.
