Hello all, just recently picked up a yamaha kodiak 400 4×4, 2002. I think I got it for a steal because it was one owner, who was 65 and drive it just up the driveway to get mail and back. So very low hours (even though there is no gauge).
Any how here are my issues which for the price I don’t really mind a few fixes ( I paid 1500 for this like new cosmetically quad). It’s worth mentioning I think she passed so it has been sitting for about a year (in a heated garage).
Issues are as follows:
1. Horrible cold start (and I mean cold right nite all it’s 35F) so not really that cold.
2. Backfiring more often than it should.
3. It will stall unless I have the choke at full for about 2 mins. Then halfway for about 5 more. Our it will stall.
4. I heard some very faint knocking in the engine.
5. Carb reside nite in plug
6.
I enclosed a pictured if the spark plug and air filter.wanted to get your opinions if the plug indicats lean or rich. The plug is not wet but is black, probably carbon fouling. I checked and the gap is correct as what started in my manual. I also cannot tell if the air filter is stock and if I need a new one. Her was what I was going to do. So let me know if I should ot not do what I’m about to do.
1. Empty tank and out fresh 93 octane in. Also add assume seafoam.
2.change add plug with correct gap
3 clean carb
4 clean air filter and re oil
5. Clean spark plug
6. After cold start it ramps up in idle speed almost so much I can’t shift.
So am I running lean or rich as per picture? And is it the fuel or oxygen which I’m getting to much of.
Thanks any help would be great! Have a great weekend!
