Hi guys,
Been looking for a while with a lot of great info. I have a 87 warrior that has been a total beast since 98. Best 500 I ever spent. Recently I decided it's time to show some love to the old girl. First thing was a new clutch. Afterwards I realize it was running lean. Backfires when letting off throttle. I upper the main from 145 to 147 then to 150. Raised and lowered needle. Finally I had a 152.5 ran ok. Ok as in it would run decent at times then at times would pull hard like it should. But it was intermittent. Its stock with the air box lid drilled and stock pipe with guts removed from tail pipe. I pulled carb this weekend soaked it and reassemble it with the 152.5. Still lean, even with air box holes tapped up. So for the hell of it I took the stock 145 and drilled it to 3/32 Still lean. Went to 7/64 and it was fat as hell. Played with needle no luck. Today I took another 145 and drilled a 3/32 and played with needle again. Still fat.
Intake boot is good, I've had that before. New petcock on tank. Spark seems good. Can't tell on compression, don't have proper adapter. But it is or feels tight. Hell I can almost pick up the whole thing trying to pull start it.
Am I just going to far from 152.5 to the drilled out jet?? Could I have a week coil?
Plan on getting some larger jets. 160 range I guess. Any thoughts?
