03 stock stroke and bore ported cylinders,cut head,boyesen reed petals stock cages, stock carbs,k&n pods, have 360mains,27.5 pilots air screw 2 1/2 turns out needle on 4th clip, Toomey needles. Put new plugs warmed up and ripped down road shut down full throttle. Its lean as hell. Seems like 360s would b way big. I'm outside of Detroit. Any opinions? Thanks in advance

360 main is big in these summer temps IMO sounds like you have a air leak. Should be around a 330-340 main since it's ported. New intake boots and gaskets with yamabond on them might fix the issue. How old are the intake boots? Have they ever been replaced? Did you do a leakdown test? Post some pics of the plug so we can see it.

Where are you reading your plug at? Are you actually cutting the threads of plug and reading the burn ring at the base? Or are you just looking at the porcelain in general? This pic is from another thread but its just a reference for ya. 5ura4e4e.jpg

Where outside Detroit are ya? I'm not working for a few weeks and am bored as hell. I'm in right between Waterford and White lake. Let me know if you want some help sorting it out.

I didn't do leakdown test. Intake boots are original stock. Didn't do plug chop only plugs I had lol. I'm working now. Gonna mess with it this evening. I'm leaving for silver lake Wed night. If I can't get it tuned I'm jus putting t5s back on. Couldn't post pics. I'm in Belleville. Basically 94 and 275 I'm ten min from detroit metro airport.

Sounds like you have an air leak, that jetting is way off for your mods...... I just re-jetted for the warmer temps and am at 32.5 pilots and 340 mains (ported 4mill on pump fuel)... I'm not too far from you.... I'm in Westland, Mich. Ave and Venoy area...  If you can't get it worked out, let me know I can help you.
