Thanks, mine is on the bottom notch. Just wanted a reference point.
Looks like I'm going to have to pick up some shims tomorrow...Thanks guys, this thread is great. If I can figure out how to replace the pilot jet in my BS29 I'll be taking mine for its first test drive tomorrow after work.
Thanks for the info and the offer of the diagram- I think I know what I need to do now. I'll try and get the pilot in while it's mounted to the machine, but if I need to move the needle or add shims, I'll have to bring it inside somewhere clean and safe, right?
These tiny little shims are available at any Jap bike dealer with a good stock of Mikuni parts.
CV's are awesome ride a day carbys when set up decently. Very forgiving of seasonal atmosphere and altitude changes and very efficient at atomizing the fuel and mixing it with air. They can be modded for increased performance too.http://www.indiancarsbikes.in/automotive-technology/crisp-punch-ported-throttle-slide-cv-carb-9399/
I've actually done this, and the response from the throttle is noticeable. Not a 'stellar' increase in performance, but responsive is the best word to describe it.I was worried about messing with the only slide I had, so I ended up contacting the author in the article to order an additional slide. If I recall, it cost about 11 USD + about 25 in shipping from India. So I have 2 slides. One thing to note is that I believe as a result of this mod (I say believe, as I changed a whole number of things and cant be certain the slide mod is the root cause), is that my starting procedure really changed. After rejetting, and opening things up, I couldnt start the bike either cold or hot consistently. Before all my mods, I was kicking it easy with just choke. Not so after the mods. It acted like it was missing air. So now, I hold the throttle at about 1/8 open on kicking over (which should be a no-no), and I get zero kick back and 1st kick starts; hot or cold. You may not experience the same thing as each bike has it's own personality. It works for me. Would I do it again? Yes I would... I like the CV carb, but would like a little more performance out of it between 1/8 and 1/2 throttle. When I wack it open, it goes nicely!
Just for my future reference do you recall what size drill bit you used?
