never had a digitron on any of my sleds, but on my diesel trucks I run a pyro, aluminum melts around 1350 degrees F. I always try and keep the pyro below 1250 to be on the safe side. Hope this helps.

Need more info...All motors read different....My '02 800 runs safe at 1300...My '07 600 runs safely for 5 minutes steady at 1400 degrees...Yeah I know that sounds too HOT but it is what it is!!
Mine reads around 1300 most of the time but occasionally up to 1350. Plugs and piston wash are good.

mine reads 1250 to 1325 when its running at its best. there is a big power difference between 1100 and 1250 so i would consider 1100 and any less to be way rich
Jkinzer do you have the probes in the y pipe??

02 800
Edge, and i figured 1300 is a great number to hit! Should I put the probes as close the the power valves a possible?

Every engine IS different and it is critical to correlate EGT numbers with plug/piston wash checks. Keep in mind as well that as the fuel mix leans out, EGT numbers will peak, then begin to fall as detonation sets in. Don't automatically assume that a low EGT reading means you're "safe".

put them as far out as you can on the Y pipe...be sure not to go too far out and get mixed flow though. About where these holes are on this picture....

Probe location
I have always placed them further then that....Do you think another 1/2 " or so would see flow from the other cylinder?

Aftermarket pipes generally make a motor run leaner then with the stock pipe...The difference in "safe" egt readings from my 600 and 800 may be due to the exhuast port size ,shape and timing....I suspect the 600 reads way higher because the flame is getting closer to the probe (even though the probes are located the same distance from the cylinder)
ic so your going off of the same general location "probes" and judgeing by wash and plugs. so your 600 and your 800 both have the same wash and plug color only difference is the egts, wich i could see because there two different engines, in thearoy the aftermarket pipe should only make it lean if it was makeing more power.

Yup , thats right

Not necesarily...it very well could work, on my application i just felt that I needed to keep them as close as i could to 100% no mixed flow...its kinda crucial for my turbo set up to read correct...i would guess that a lil further wouldnt hurt...
