29mm Smoothbores

[Vmass]

This is my first set of smoothbores! I am looking forward to opening them up and refurbishing them. I may even buy them an Ultra Sonic cleaner.

I will dig in a little deeper, but I think I need 3 gaskets and 4 O-rings for a refurbish and then of course jets and needles if needed.

Those look to be in nice shape and should clean up nicely. I've restored a few sets of those and resold them for good profit on ebay. The Kawasaki guys are gaga over them.

I think I've got a full O-ring set for them if you are in need. You can order from Z1 as well. The jetblock gaskets are fragile but sometimes you can save them. Also, be careful of the jetblock screw threads since they often strip out.

If that brown varnish is gluing the slide inside the body use a hot air gun to soften the sludge. Often the slide will fall free after heating whereas soaking in carb dip can't get inside to where it needs to to free them up.

Good luck.

Thanks, Ed. These actually came off a KZ900 I picked up locally. No title for it so I am not sure of it's fate.

The slides are glued and great idea with the heat gun.

If you don't need the O-rings, I will be happy to use them. You can send me a PM with the total and I will Paypal you.

I did read about the jet block screws being fragile.

Hey Rich,

If you have some calipers please measure the air screw and fuel transfer tube O-ring sizes. I've got a box full of O-rings and need to refresh my memory as to what ones fit the Smoothbores.

Edit: found the sizes. BV30/40 - fuel transfer tube O-rings are 8.70 x 1.95mm, VM14/75 for the air screws are 2.50 x 1.55mm.

Thanks again, Ed.

I checked out Z1 (glad they are back) and they appear to have everything needed for the carbs. I will put an order through with them and let you know only if I come up short.

Regular VM Robert Barr kit for all the standard orings, bowl cap orings, and jet block gaskets, and new bowl to body gaskets are all you need. Note the jet block has a small hole on the engine side..be sure its clear and the gasket and jet block line up and dont cover the hole. As youll see there arent pilot screws on VM29s...the hole at the back of the jet block is the pilot fuel hole.

Would this be the air screw o-ring:https://www.z1enterprises.com/product/KL18-4636-1

Best bolt on performance you can get.

Description says 2.4mm x 1.6mm so it should work fine.

Nice timing on you getting these as I have just got a set too. Appreciating all the info being provided.
Awesome. I cant wait to baby my set also and try to give them the royal makeover.

I just started to rebuild a very rough looking set of 29's as well. found in an attic with unknown history. They need a bit of work but are salvageable. Follow the progress on my Facebook page here...... https://www.facebook.com/Agemax.carbs/

Yes. Very sorry looking. Lol
Your fb page is really awesome. I took a short stroll and saw a lot of good work.
It was weird, at the top you have the phone number and I had to do a double take. It looks so much like mine.

That last set of of VM carbs you were working on look spectacular.
Thanks for sharing

Nice work Agemax! Since there is some interest, I will post more pictures as I proceed with mine.

Do you polish the needles, floats etc. or are they brightened by a particular solvent?

I polish them, i am a sucker for shiny things. Wont help them work any better but they sure look nice when you drop the bowls off!
