Carb parts?

I got sand or dirt in the carb at Pismo last weekend, making it run poorly, so I took it apart and cleaned it. The accelerator pump diaphragm curled up as i took it apart, but i thought i got it all back together correctly. I must have torn it somehow, as now it leaks. Where do I get the little parts for the carb? I've got the 650 Sand Spider, 2 cylinder, one barrel side draft carb.

Hi

Thear are no parts around to fix this.I can not find any and joyner never sold parts to rebuild it.We some times use a solex carb.But we had to fab a new base to make it fit.I ran good but it was a lot of work.Wait till some more come in stock.Maybe you can find a carb rebuilder he may have some thing

I found a place called "Fast Freddy's" in Santa Ana. They make a two barrel Weber side draft carb setup for the 650 Sand Spider. It isn't cheap, but it comes complete with every part needed to fit the Weber in your Joyner buggy, and forever eliminate the goofy Joyner carb setup. They also will modify your header for better output, or tell you how to do it yourself at a local muffler shop. When the parts come in I'll try and do a report on how it goes.

Fast Freddie's has a header solution, as well. I got the instructions, and figured out how to build my own. Here's the start - a 2" 90* mandrel bend and a 2" straight piece. I'll take out the original collector and put this in its place.

I tried a kit from a place called 6 Sigma Racing, off of eBay. Stay away! They sent me a few sheets of paper with various random non-applicable carb tuning tips, a bad copy of some service manual drawing for a carb other than the one I have (2 barrel vs. one barrel), three jets and four tiny drill bits. The photos and drawings depicted drilling out the pilot jets, but I don't know on what carb. When i tried to contact them, no response, so I filed a complaint with eBay, and then they got all nasty..... He said he'd refund my money if i sent it back, but no such thing happened. Beware!

What happened to parts from fast Freddie?

They haven't come yet. Apparently, the parts were not all on the shelf, some had to be made, such as the manifold, which he said they machine from aluminum. The 6 Sigma parts were before the Fast Freddie order, and they obviously weren't going to work, or more accurately, they weren't gong to reply to my questions, so I kept looking. Interesting thing, when I moved the buggy from the carport to in front of the garage to work on the suspension while waiting for the carb, the accelerator pump didn't leak fuel. Self repair? IDK, but that doesn't mean I trust it. Weber will be better.

The parts came from Fast Freddies last week. Nice Weber DCOE 45, and a couple of manifolds to adapt it to the Joyner head. 45 is huge relative to the ports in the head, but i didn't feel like pulling the head to do a porting job. The gaskets are hand made, and not what I would put on, so I didn't. I modified the provided gaskets for full flow, made a few other changes, and got it mostly hooked up. Still need to plug the water hole where Joyner had coolant running through the manifold.

Thanks for keeping us updated. Even to we are not much help with you Joyner we still like to know what you had to do to repair.

I don't know if it is repair, or preemptive upgrades :rolleyes: When i put in the rear Airshox, the upper end had to be on the beltline frame rail, and based upon the fine work i found on the control arms, I figured it was easier to tie the new spring/shock mount across to transfer the loads before I bent the dickens out of the whole frame. The header upgrade was simply changing the collector pipe out for the size that the math called for. The amazing thing is that the Joyner muffler was also 2.0", which was the size the collector should have been, and they put a swedge adapter in place to change the pipe from the 1.5" to the 2.0" just before the muffler. I had to move my muffler anyway to clear the new shock location, so changing the pipe size at the same time was a no brainer.

As to the carb, I'm in the process of changing tires out (the Joyner wheels no longer fit the frame with the new shocks) so i can take it for a spin without paddles, which could be upsetting the float level and causing my carb tuning issues. Then I'll check the floats, if that doesn't change anything.

The parts came today, I put them in in about 10 minutes (less than half a beer) and with the right jets that buggy screams! Not as fast as my RZR, but a very nice ride. I did some bad bumps, and the Airshox in the rear are much smoother than the stock coil overs in the front. :D

      Hello all. I am new to this forum and new to SxS in general. I recently purchased an 16 Odes Dom 800 with the issue of a prominent knocking noise at idle and it’s very jerky in forward and reverse gears. It does not sound like an engine knock. I bought it cheap knowing about this problem with hopes of it being a cheap and fairly easy fix that I can do myself. Would a bad belt be the cause this symptom? I’m looking for a starting point to begin diagnosing and fixing the problem. I recorded a video of it but am not sure if I can post it on the forum. Any help is greatly appreciated.

      Hey Guys, I have been chasing a stalling condition for about two weeks now. The bike will crank up and idle fine, then after about 20 seconds it will fall on its face and stall. It happens at both idle and while running at various rpms. You can turn the key off, turn it back on and it will fire right back up without trouble. I have verified spark on both cylinders with a spark tester. I have also added an inline fuel filter, and pulled the injectors to verify proper pulse on each. Things I have replaced - (relearn procedure performed after each component replaced): spark plugs, ECU, relay/fuse box, fuel pump, & throttle position sensor - all with no improvement of the condition. The only warning light I get when the condition occurs is the oil lamp. The bike only has 14 miles. I am at a loss and appreciate any help and suggestions! Thanks

      Hopefully someone out there is a T-Boss 410 electrics expert or a Massimo mechanic is viewing this. I parked my 410 and it was working great. I came back a week later and attempted to crank it and nothing. Turned the key and no power. Figured it was a bad/low battery so I charged it. Still nothing. Attempted to jump start it and still nothing. Usually when I put the key in and turn it to the first position, the display comes on and I hear the ECU and other items boot. Now it is doing nothing. 
      I slowly went through the electrical system and found the main fuse attached to the starter relay, part 71602 (pic 1) blown. I figured replacing this fuse would fix my problem. It didn't. I then ordered a new starter relay thinking maybe that part had gone bad and caused the fuse to blow, but a new relay did not fix the problem. 
      I have found a work around for starting the machine. If I take one of the purple/black leads (pic 2) and insert one of them in the bottom right of the starter relay (pic 1 and 3) then the machine will get power even with the key in the off position.  I'm bypassing something but don't know what. I can use my right hand to hold the wire against the lower right of the starter relay, reach over and hold the brake with my foot, then take my left hand and turn the key and it will crank. As soon as I remove the wire from the relay the machine shuts down. I have even removed the power distributor box and it will still get power when I touch the wire to the relay. Of course this is not the way it should work but if I can't solve this problem somehow I may just have to rig a connector to the relay and bypass whatever is causing the electrical issue. Massimo has told me the purple/black wires on my model are not used.
      Any help in figuring what my problem may be or other items I can try?
      v/r,

      We have 2.4 acres of forested mountain property with about 1000' of gravel driveway to plow and maintain.  My trailer is a Silverwing SW9f 5'x9' and we would really like to have something that seats 3 people.  I looked at Polaris, Yamaha, Can-AM, Kawasaki and so far the only thing that fits the bill is the Polaris Ranger 570 full size. 
      Just wondering if anyone else has ideas of other options new or used that would fit this?  I really like my trailer and it will be great to use behind the UTV also when i get it so i hate to have to get something different.
      Thank you!

      Hey all!! I have a 2001 550 that won't or run. Good spark and gas to the new carburetor but it seems no fuel to spark plug. Any suggestions? Thanks!
