what is the best sparkplug you can fit in the kawasaki kx85 for maximum output and power?

Question

Trying to get maximum output out of kx85, any ideas on how to do this plus what tyre preasures would yor run it on on a slippery and a damp track

Answer 1

The spark plugs only role is to fire the mixture. There is no performance to be gained from the plug alone. If the plug is to cold, the mixture won't burn properly, to hot and you could burn a hole in the piston.

Tire pressures vary with the tire. For instance, I've found that on Michelin S12's anything below 10lbs will give you sidewall flex and the handling becomes vague. Over 13lbs and the tend to 'bounce' for lack of better words. At the same time, the Pirelli MT44 front loves about 8lbs in soft terrain and no more than 12lbs in the rocks or roots.

Play with the pressure on your tires and see what you find. Just be sure the rim locks are in place and secure.

Answer 2

The stock tire pressure is 15psi F & R
For a wet and slippery track I'd drop it down a little.
Try 12psi - no lower than 10

Answer 3

height or max values is what the kit can deal with for a split 2d before failure starts. it really is carefully ineffective information. RMS (Root advise sq.) is the continuous means.

Answer 4

spark plugs do not affect performance. when you buy them you buy quality ones for long lasting.
