Yamaha Moto 4 CDi Box


Brewster

Recommended Posts

Being confined to the farm with the corona virus pandemic, I have started working on long abandoned projects.  I have a 95 Yamaha Moto 4 350 and the CDI box went bad (I think).  Finally broke down and spent the money for a new one.  It had the same part number as the old one, but the old box as 2 extra wires on the pig tail and not all the wire colors with the new box match the old box, so I'm not sure how to hook it up.  Have searched the internet on and off for some time but can't seem to find anyone who can help.  Does anyone out there know enough that they would try to help me?

Does the colors match up. They may be in the wrong spot on the plug

You may have to switch plugs.

I'm not sure if the same CDI was used the entire run between 87 and 95, but I know the early Moto 4 CDI's were actually the CDI used on the last year of the 3 wheeler.  It was unlike the rest of the Yamaha quad line and is quite an oddity.

Do the 2 extra wires connect to wires in the harness?  Or do they connect to blank spots on the plug?

If everything else matches. Then move those off to the side. What I would do is remove the pins out of the plug. This can be done with a pick. Something small enough to get the tab to move to pull it out. Then connect said matching colors. There should be 2 wires of the same color left. Do you know what machine the new one came out of? If so get that diagram and your diagram and match them up

Personally if i broke down and spent the money on a cdi it damn well better be the right one! Plug and play...... what year is your machine and what did you buy? Oem or aftermarket? Id it possible they sent you or you ordered the wrong part? 
 

The last thing one would want to do is start chopping up a harness after spending money on a cdi.

      I have been exploring all the options available, so many, its hard to choose. I have kind of narrowed it down to the Honda Pilot, Subaru Outback, and Kind of looking at the Outlander, although its a little small,  the new one is nice looking. Just wondering if anyone has any recommendations or gripes with any of these rides. I have driven Jeeps for the past 25  years and they have been great, but their price point has gotten to high. Expieriences good or bad would be helpful. Thanks!

      Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
       
      Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
       
       
      Any help and information greatly appreciated.

      Hey all,
      I need some input on a problem I'm having with my Kodiak 400 that keeps fouling plugs. First off, I've done a lot of work to this thing, most of it all in good fun. Brake work, cv joints, u joints, carb kit, checked valve lash, compression good, changed all fluids, etc... My problem is it keeps fouling plugs very quickly. I can put a new (manual recommended plug) in and it starts right up, runs great, idles great, picks up good. Doesn't stutter at all. I ride it for 1/2 a mile, it cuts off and won't start back up. I let it sit overnight thinking maybe it got to hot. Try to start it the next day, nothing. Put a new plug in, fires right up, runs great for another 1/2 mile or so, dead. The plugs come out and look carbon fouled with dry black soot on them. I don't know if this is a fuel/air mixture problem or a ignition problem. A couple of things that I noticed is I never need to pull the choke out to start it. Also, when it starts it automatically idles high like an automatic choke would do, then it comes back down to a good idle. Also I noticed that the air/fuel mixture needle valve screw does nothing when I adjust it in or out. I can screw it all the way closed and the motor still runs and idles good. Any advice would be greatly appreciated. I'm almost leaning to a ignition breaking down the plugs??
      Thanks!

      Hello I’m new here and was wondering is anyone knew of good replacement part numbers for front struts and rear shocks for this atv? I think I’ve found a new rear shock, that looks like the original but there is no dimensions or anything and was wondering if there are any afterMarket new front struts available. I know it’s a long shot but any help would be appreciated.
