Jetting help

Recommended Posts

Well, I think I have a bog when I take off. I have 300 main jets, stock pilots, 1.5 turns on air screws, K&N w/ proflo adapter "outerweared", V-force 3's, and T5's. Well, my plugs are a chocolate brown like a new cardboard box. I also have black premix/oil on the tips of my pipes(a wet black ring). Is this normal? I run 32:1 Yamalube(4 gal. gas to 16 oz. of premix). It is around 950 - 1050 ft. above sea level here in MISSOURI and 60 - 90 degrees F. Well, help me out if I should try somethin else.

Your main jet means nothing on take off...that's all pilots and air screws...

Try turning each screw all the way in seated, then back them off 1.0 turn.

 

I wouldn't pay too much attention to the color of the insulator...unless you're doing a proper plug chop. With time, they normally color...but, that really doesn't mean a whole lot. Your mains could be lean as hell (you're not in this case...but, just for example)...but, if you spend most of your time at 1/2 throttle or so, you're never on your mains. So, you'd be getting coloring from the pilot and needle...

 

I agree...I think you're a little rich...but safe, on your mains.

 

Here's how to plug chop:
