Drilling CV Carb Slide Holes and Driveability

[Guest]

Well what is a thread without pictures...

First time using JB Weld. Thought it would be more of a liquid, so the syringe method didn't work all that well.



Didn't let the JB Weld cure long enough before trying to drill, so I drilled it all out and filled it with Permatex Steel Weld which sets up faster. Went with larger syringes which worked well, but it hardened before I could get to the last two so I just stuffed it in there.

I'm leaving the epoxied holes alone and drilled on the opposite side. Based on the internals it doesn't seem to matter where they are drilled. However, I should have triple checked the drilling location because they definitely aren't out towards the edge as much as stock. They are drilled at an angle though. Side note, you can see just how massive that 5/32" hole is in comparison :shakes head:





I'm going to toss these in after cleaning them up tonight or tomorrow and see if they work. Otherwise a gracious member offered to sell me his correctly drilled slides from when he ran a dynojet kit.

Personally, I found out the hard way the drinking and wrenching don't mix. I was drinking when I incorrectly drilled my slides. I wasn't a mess, but apparently had enought to not pay full attention to the task at hand. Since that night in '99, I'll take a celebratory drink when im finished and admire the coolness that is my bike, but not during.

No intention to preach, just my personal experience.

That was the only beer I had, unfortunately. But sometimes I need a little liquid courage. I tend to overthink EVERYTHING, so I don't get anything accomplished. So sometimes a few beers help me say "screw it", and I just get it done.

Understood. Everyone has their own process. I never thought of JB ing mine, I ended up buying another used set to the tune of $400. To add to insult, the first set the cycle salvage sent were wrong. They made it right, but cost me more time. It was a lesson well taught.

Eek! $400. Granted, I probably spent close to $300 rebuilding and re-jetting mine, with some more on top if I have to buy some new slides.

Measure twice, cut once!

Or in my case, just eyeball it

Got them in and the bike definitely rides better. It's not a massive change, but it's an improvement. I still need to adjust the clips as there is a little bit of hesitation when rolling on at low RPM.

I would not suggest doing what I did though and drill on the opposite side as the original hole. You'll notice the plastic insert that sits above the needle has a little nub on it in a specific spot. This actually puts an angle on the needle leaning towards the hole, or intake side. I'm not sure what the purpose is of this, but mine now lean the opposite way.

So you just drill the top of the slide ? Can this be done with stock jetting?

I would not drill anything, just leave it as is
