I really lost myself this weekend

Matt, that is xactly why I like to know the reason for needing to know what your head temps are telling you.
I imagine that your goal is to keep temps as low as necessary to maintaing an efficient system.
But which part of it exactly?
Or are there many other factors you are after other than over all efficiency?
I know that avoiding overhating it will preserve the life of your motor. But is there one specific matter or issue you are trying to keep under control?

I think Matt had some past scuffing issues he's trying to avoid on his recent build.
In my case, I'll take a look at HT just because I already have the gauge, and 5 minutes to rig, just another evaluation tool., what I don't want to see is a big difference between front and rear cyl's
I richened the carb after a rear blown head gasket a couple years ago, but it was really an under torque issue a few S&S engines had a while back, MPG's did suffer.
It's time to go through the carb, so I'm going to retune, then the temporary rigged HT and AFR meters get removed.

Matt's had back luck with a couple of builds that did show hi heat concerns... Knowing that, he's trying to keep his temps down to not ruin another build... If timing, fuel and compression are on and an AFR meter to confirm, I don't see the need to go as far as he is.... And for that An IR meter is fine... But to each his own..

All correct. This is round 3 on this motor and I wanna make damn sure things dont get out of hand, temp wise.
The irony is that even though I’m monitoring just about everything I possibly can in real time I still have no idea where the official temp threshold is. Just suggestions and conjecture from others where I need to grow concerned. At least it’s a guide, but it would be nice to know for certain what blew up my last two attempts at a 107” Evo.
I swear to god if this one pops I’m gonna buy the cheapest stock Evo I can find and trade the bike in for a newer Twin Cam based Road King.

Following your build since the biggining. You have every right to protect your self from destroying another build. Or you can ride like an ole lady. Problem solved
Joking aside tho, I’m beginning to wonder if the MoCo base Evo or twink has wat it takes to get big.
Bigger than 110.
Think about what they did to get to 103. 110 and I guess they can sell you a 114 in twink form.
Now they have the M8. From what I read. They’re a crap shoot.

Yes actually, I helped my dad rebuild a 1996 Dyna. This is a great idea! Thanks.

That's the cleanest 89 I've ever seen tho.
