K so did a little investigation yesterday afternoon, fairly frustrating...
Carbs seem ok, mains are 210's pilots are stock, inside of carbs clean and seem normal.
Compression, good on both cylenders and withing a psi of each other. What is the stock compression????
Air filter is old and stock, but I tried running without it and it made no difference
Brand new 92 fuel, good oil, proper mix.
so here it is..
Idles and revs in neutral like a champ. Idles in gear not bad, but the second you give it some throttle in gear it drops a cylender. Always the left side. Every time. Keep you thumb in it or feather the clutch and it will come back, but unless you are high into the revs in will cut out again.
I did a plug check several times, right side burns nice, left side always washed. And I mean washed. You can also tell at the exhust joints and muffler tip of the left cyclender raw fuel and oil.
Disconnected tors no help.
Tradded the plug wires back and forth the washed plug does not follow the plug wires, both seem to have plenty of spark.
So I drive in first second, what ever gear, mid to low RPM and it will only run on the right cyclender, loads right up on fuel. But if it just sits idling, it will run on both, or if it is really high revs it will kick the second cyclender in.
If I do a flat out run all the way through the gears, I can maintain both cylenders at high revs, but the seccond the revs drop I loose the left cyclender again. Always the left.
One other thing, starting stone cold, with float bowls dry. Choke to get er going, then hop right on the throttle, runs like it should, for a minute or less. Then starts to load up on gas within a minute or two, and back to the same problem.
Not surprising but it seems to be burning a tonn of fuel!!!!
Anyhow, what would be causing this???? Gotta be something in the carb??? Reeds??? Bad motor????
Any help would be great!
Thanks
