A Million thanks to member Mike Brood for emailing me a very detailed "carb parts breakdown list" which helped immensely!!! Here is the link that you guys can copy and paste to get the list.............................................http://www.bergall.org/temp/venture/venture-carb-part-differences.html

Hey guys, I'm in the process of rebuilding the carbs on a 86 XVZ13 I just bought. I would like to know if any of you have used the 18-2879 K&L carb repair kit on an 86. This K&L kit is for a 85 Vmax and it was a perfect fit when I did the carbs on my 83. I've researched other posts on this subject but I want to make sure before I spend the money!! THANKS

Ha! Funny thing is, I broke it with a screw driver instead of a hammer! :-)

I agree! Earlier in the thread I posted details and pictures of how I checked fuel levels in each of the four fuel bowls that you might have missed. I set levels right at 14mm (+/- .05mm) below the center mark per the service manual. I made a line with a permanent marker on the side of the carb body to make it easier. Here are a few pictures.

Thanks for the heads up. That is one of the steps that I forgot to put on the list! I checked for that and the PO must have wet sanded them down because the edges were very smooth!

Ok guys! I haven't posted anything on the thread in over six weeks because I've been.........let's just say..........busy with my 83!!!! I've done many repairs including a complete rebuild on the carbs, which is why I started the thread in the first place. I am glad to report that the break I caused on the carb body did not affect a thing! You guys got it right. I adjusted and synchronized the carburetors and "she" idles and runs beautifully! I attached pictures of some of the steps in the rebuild process if you guys want to check them out. Here is a list of what I did/replaced on the carburetors: - complete disassembly of all four carburetor bodies - a detailed & deep cleaning of all parts, jets & passageways using varies methods (soaking & spraying w/cleaner, compressed air, media blasting w/baking soda, brushing) - 4 new gasket/o-ring kits - 4 new diaphragms (old ones had tears and pin sized holes) - one new float in carb #2 (old one was deteriorated & taking in gasoline) - new (Allen) bolts on all 4 slide/diaphragm covers (the stock Phillips heads tend to strip) - new hex head bolts on all four support brackets (this enables you to get much better torque when attaching carbs back together) - all new fuel lines and hose clamps - all new (4) fuel bowl drain hoses - checked (and calibrated when needed) float heights with digital calipers (1.025in. worked great for me in achieving the next step) - set fuel levels on all 4 carbs to 14mm (+/- .05mm) below piston valve center mark - synchronized carbs with vaccum gauges (I will say that it took me almost an hour and a half but I got it right on the money!!!!) - adjusted all four air mixture screws to approximately 2.5/3 turns out (this also worked great for me; not too rich or too lean) It is possible that I forgot to list a few other things/steps I did to the carbs but overall my 83 runs and idles very well (I set idle right at 1,000rpm). I had read and heard the difference that a full rebuild would make but I was blown away at the results!!!!

ALLLRIGHTYYYYY GUYS! Taking into consideration all the info I have received, I will take your sound advice. I will leave the carb body as is!! Once I have put the carburetor assembly back on the bike and synchronized them, I will give you guys an update. Hopefully it will be good news!!!!!!! Thanks again to all those who chimed in!!! GREAT SITE! EVEN BETTER MEMBERS!!

Thanks for you honest input Dan!! I will say that I bought some JB Weld already but seeing as it cost me less than $5, I will keep it for the next project!! I'm leaning on the cautious side of leaving the break the way it is. Hopefully, it won't pose a problem when I synchronize the carbs! I'm open to more suggestions though.................

This is exactly why I'm waiting for more feedback! I can see the risk that JB Weld poses. Wouldn't want a damaged valve or worse!! Thanks for the warning/observation! Believe it or not, I have never used JB Weld. Would it bond well enough to the surface of the porthole to prevent it from getting sucked into the engine? I would love to know if anyone has successfully repaired a carb body with JB Weld in an area of low stress/pressure................ more importantly, has the repair stayed intact over time??:confused24:

I'll wait to see if I get more feedback before I make a final decision. I appreciate all of you that have chimed in so far!

JB Weld! Good idea! Hadn't thought of that. Although it might not be necessary (from what you guys have posted so far) I'll probably do it anyway just to be sure. Also because..................... I know it will bug the heck out of me knowing the break is there even if it is not visible!!!

I agree!! I posted the thread as a precaution before I put the carb assembly back on. I would hate to not be able to synchronize carb #1 properly because of the damage. I'll wait to get more feedback before I proceed though. Thanks!

Hello everyone! I became a member just today. I am truly overwhelmed by the wealth and diversity of knowledge on this site!! While rebuilding my Mikuni BS34 CV carbs, I broke a piece off of carb#1!!! To be more specific, it happened while removing the pilot air jet #1 from the top part (venturi) of the carb body. While applying downward pressure with the screw driver, the carb slipped from my grip and I broke a small piece of the "housing/port hole" (for lack of a better/proper term) where the pilot air jet #1 inserts in to. My question is this..................... Will the larger opening caused by the break affect the airflow/vacuum (proper functioning) of carb #1??? My reasoning is that the air will still be "bottlenecked" through the hole in the pilot air jet (which I cleaned successfully and is not damaged) no matter the size of the top of the "housing/porthole". I need to know if the carb is ruined (junk) or if it will function properly. I know there are good people here with much more knowledge on this subject than me! I would appreciate your impute to figure out if I have to start looking for a carb #1 replacement or not. I have attached two pictures of the broken section to make it easier for everyone to understand. THANKS!!!!!!
