I am trying to diagnose a no spark issue with my 02 Big Bear 400 and I am really hoping it is not a CDI. I have done the test on the stator and I believe that is faulty. I ordered a new aftermarket one from a the jungle website and it tested bad right out of the box so I am waiting for a different one to arrive from an ATV parts supplier. I started looking out of curiosity at CDI units and it seems if it is for a big bear you are SOL. Kodiaks, no problem. Big Bear. No such luck.
I have this bike in my shop for a customer. It was sunk completely under water and left running until it killed. I did a complete engine rebuild. Replaced all bearings, crank, oil pump, and various other components. Engine starts and runs great. It will shift up through all gears perfectly in automatic and in ESP, but when slowing down it gets to 3rd gear and the MIL "-" light comes on and stays on. No flashes or anything and it will not shift gears. Kill the engine and restart in ESP mode and it is able to shift to neutral and start over. Does the same thing while down shifting in ESP mode. I replaced shift angle sensor with no improvement. Checked oil pressures as per repair manual "74psi" and higher with higher RPM's. With no MIL codes to point at an issue. I am at a loss as to what else to check or replace. Has anyone else ran across this issue?
When you and a group of friends decide you want to take a long group trip of camping/riding/overlanding, how far are you willing to drive for your trip? Right now, i find it really difficult to want to drive more than 2-3 hours one way.
