hey guys! nitro season is afoot and im looking to find a decent setup for this motor. i only had 5-6 club races on it last year after break in, and while it was fast, it was a little fussy to dial in. its still on the rich side as our track is quite small with lots of slow corners. so just a lot of blipping between them ect.
typical parking lot.

Our track is at sea level. i expect 18-28C which i know is quite a range in temps, but ill be running on 20% fuel likely.
should i stick to the RP6 plug that comes stock or should i consider a colder plug? I remember very good results with my old os12tr going to the cold plug on 20%
the guys im competing against have murnans which i know are very fast but shouldnt this have kinda similar rip?

Im also curious if the sc1070 is an ideal pipe for this motor on a small track? or should i consider a different setup?

sadly, no perm facility and i can only make it out every two weeks in the outdoor season. any help i can get is much appreciated!
