I took the carb apart. It appears that the main jet from the rebuild kit is smaller than the one I took out. So I swapped the main and pilot jets back. The quad runs a good as it has so far. However if I hold the rear wheels off the ground I can gradually increase throttle right up to the point the rev limit comes in. Instead of staying on the rev limit it will die-comeback to full throttle- die- come back to full throttle and keep this up. I took a short video but it doesn't appear that I have forum rights to post. I'd be happy to email to somebody to post for me.

Anybody?

I called the local dealer. They say then can test the coil, but not the CDI. I wish I could test this thing before sinking the money into a new one. The service manual doesn't really have anything that I've seen as far as testing it either.

Thanks,
Craig

 

You need to call Chris Grissom..Suzuki of Paris Tenn.
If he can't help, nobody can.
Sorry, don't have his number.

 

Thanks for the lead. I'll research it and see where it goes.

Hopefully I'll get some help.

 

I finally have some closure to this mess.

I purchased a PROCOM CDI unit. This unit does not work on my 2006 LTZ50. I called PROCOM before purchase, and they told me that it would.

I reinstalled the OEM CDI unit and began more work. I used an oscilliscope to verify the pick up coil pulse, and also the pulse generated by the CDI. At higher RPMS, the CDI unit quit functioning.

All this time, I was conducting tests with the battery removed. This was a mistake. This 4wheeler requires the battery to function correctly. I purchased a new battery, installed, and the 4wheeler runs as it should now.

The PROCOM CDI unit still doesn't function.
