So I've had a polini for awhile now, and I soft seized it about 2 months ago, and I determined the problem to be electrical (crappy spark). I had it all dialed in prior, and before the issue, it was very fast and quite reliable. The cylinder never really got that hot running like half advance timing.
Today we put together a ported polini on my magnum and it FLIES. Its actually pretty crazy, easily doing 50+ on 14x36 gearing. The jetting appears spot on (19 phbg, 106 main, w7 needle fully rich) with nice chops and good power throughout. I am running full advance (as per creature advice), but this shit is getting HOT. Its not quite as hot as when I seized it, but its up there, and I worry how long it could take the heat. Is this how the racers run it, or is there something to cool down? I know full advance is notoriously hot, but I know some dudes run full advance on polinis for days at WOT. I don't really want to seize this one (as it isn't mine) but I don't want to sacrifice too much power.
All advice is greatly appreciated.
Polini (ported, case matched
malossi 4 petal
19 phbg racing (106 main, w7 needle full rich)
full advance with small gaps (perfect spark)
I'd guess its topping out around 55 based on my prior setups.
