Well, if you read the mags and talk to the pros, its how they do it. Tuning by temps is a bad idea. If you do it this method (the way I posted) you still have enough lubrication. Dont lean past max speed or acceleration as that IS hurting it.

I wasnt thinking about how a noob should tune....my bad. Even so, if they want to do it right, tune by performance, not smoke and temp.

^^^I'm not saying try to get rid of the smoke, but its best to tune by performance. I know with my WS7II and the current JP1 pipe that I am running, the low end produces mass amounts of smoke. However, yes he did say that is a decent indicator that you are not too lean.

This is a quick graph I made that shows how the mixture affects power and heat. The best setting is the circled corner. As you lean the motor out it will gain power very rapidly until it reaches the optimum setting. Anything beyond that will yield very little gain in performance and will build heat quickly. This is why using a temp gun, of any type, is just a way to tell when there is something wrong or you have gone too far. Example: If you're running slobbering rich at 170 and you lean it an hour, it may run fast at 180, another hour and you may be blistering fast at 200, if you go another hour you might get slightly faster but your temps may rise to 240. That's when you know you've gone too far and should back it out a little.

The VSpec likes to run pretty hot (in my experience atleast), so anywhere from about 220 to 260 degrees fahrenheit should be good.

Just remember that at about 300 degrees or so with the crank out of the engine the bearings basically fall out of the motor,food for thought.My V-Spec runs at about 210 or so with 30% two shims plenty fastI am running it in my CRT now all 10 lbs of her.Tuning is an art and you need to learn how to do it not only for motor longevity but so you have good power throughout the range.I am still learning and with the help of other people who have the experience it helps alot.
