I've got a 700 based poo twin that was bored and ported by SLP. I'm running SLP twins made for that motor with probes about 6.5 in from piston skirt. What should my max temp I should be running at??
What EGT temps should I have??

You could do a quick search on this there's lto's of info
but from what I under stand 1100 to 1200 is good and up to 1250 MAX

Wrong, put the EGT's in the pipe and forget about them. Tune the motor to be perfect (plugs and wash) then look at the EGT's, remeber that number is good, higher than that will therefore be lean.

All three of the last posters are right. Put them in, in a reasonable position, then tune the engine via other, normal methods. THEN look at your EGT's. Sure, 1100-1200-1250 is the standard, but many things affect this. I have seen FAR higher values on my race engine, for explainable reasons. The EGT guage is simply an indicator that something MAY be going wrong.. .
Pinko The answer to your question (what EGT temps should I have) is what ever your instrument reports when you see perfect plug reaction to a given RPM and cylinder head temp or known coolant temp. Each report is independant and the number you see is important only to you with your situation. The numbers are simply pulse responses to give you a measuring scale for both performance and safety. Your reports could be in dots, Arabic, colors, x's & o's or what ever, but they all mean the same thing (burn ratio of fuel to spark). Heat report pulses per a timed ratio. go to www.f-bombracing.com read our Digatron Tech page...it gives you the concept and some testing sequences to insure that you are understanding the process to get the most from EGT and engine data management.

remember inconsitant throttle at lower rpm's
