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’m brand new to 4 wheelers and just bought a 1987 Yamaha Moto-4 350 4X4 to use for hunting. I say 1987, but not positive. The owner is not positive about the model year, but he said 1987 sounds about right. He also gave me his son's Clymer manual that covers 1987-1999. The frame has rusted just enough that the full serial number is no longer readable. I can read some numbers/letters, but it is spotty. Anyone know how to determine model and year if you cannot read the serial number? I have included photos.
So it started fine when I got it home, but it would only stay running if the choke was open even when warmed up. No identification numbers are stamped on my Mikuni carb to determine specific model. The choke is controlled by cable connection on dash, so it is not a model that has the choke lever right on side of carb. Since it would only start and run with choke open, I decided to rebuild the carb using the OEM rebuild kit. Took it apart, cleaned jets, orifices, replaced o-rings, gaskets, etc. After reinstalling the carb, the engine will still only run with choke open, but now the engine sounds like it wants to shut off and there is a consistent low volume backfire from the muffler. If I rev the engine, it sounds better, but still continues backfiring.
The fuel screw was seated at 2.5 full turns before I cleaned it so I put it back at that setting.
I’ve looked high and low trying to find a video of someone rebuilding my specific carb, but it appears there are many variations. Appreciate any guidance to get it back to running like it should. I have included photos.
Any guidance on figuring out model year would be greatly appreciated.
Thanks for your time.

Hello All
I'm kinda new to ATVs. I just bought a 1987 Suzuki quad runner 230 Dual Range. I'm having a problem finding info on it. It's very clean, only 2.800 miles. The front wheels are only 30 in.center to center. I was thinking about adding wheel spacers to give it more stability. I realize the added stress on ball joints and bearings. I'm wondering if there are any other concerns? Any input is greatly appreciated!

Sorry, bit of newbie question on Honda TRX520
Can anyone tell me if it is necessary to drain the engine oil to just remove the oil filter cover?
I recently carried out an oil change and when checking afterwards, found oil leaking from around the oil filter cover (was torqued to 10Nm). I am going to get new O rings to be on the safe side, but was wondering how high the oil level in the engine sits relative to the pump filter and do I have to drain the oil?
TIA
Nigel
