07 Dragon. I replaced 2 plugs. Both times my fault. Engine temp wasnt up. 540 miles

--- Only fouled approx 28 Champion RN57YC spark plugs in 840 miles.
Fouled approx 16 spark plugs with the dumb F----ing oil in gas tank from dealer.
--- 10 MPG to 13 MPG
--- Sometimes 32oz of VES II per hundred miles, at times 16 oz per hundred miles.
--- Approx 40:1 gas oil & other times 80:1 gas to oil ratio????
Twice with engine not running in cold weather throttle was slow to return when fully pressed & released. Thick sticky Poo shit VES II oil sticking oil pump, sticking cable would shut off engine???

'07 Dragon
1100 miles, still on original plugs. Fuel mileage has been 12-14mpg, uses 1 qt of oil in 80-90 miles.

07 600CFI, 3200 miles, original plugs.

3 plugs my fault did not let it warm up. Get 12-13 MPH top speed of 102 on a very short run. Lake conditions have been awful for top speed runs around here.

i fouled two on start up in my iq600 on the first tank of gas and havent fouled one in the last 1200 miles now.

2300 miles, 12 sets of plugs, 8-10 miles to the gallon. dealer wont turn down oil pump

Oil ratio is 90:1 with oil pump turned up as high as it goes. Per dealer this is the ideal ratio for the Cleanfire. 45:1 for the carb sleds. Didn't foul any plugs but changed them after 1st tank of gas as a pre-caution.
