28mm rejetting

[qboronyrican]

i had my motor built about three mths ago when the temp was around 70-80 ....now its 35-50 and im just getting around to putting it all back together. i was told then to put 158 mains and 50 piolets, needle(jjh) on the 3rd clip so what should i jet them at now?

 

my mods are 4mill long rod, aggressive trail/hillshooter full port job, port matched case, v3's, cool head(170-173psi), t5's, open airbox, dyna tek cdi(curve 3) and adjustable stator @+2 @sea level

Im no expert, but if your at sea level with porting and cold weather, I dont think any 100`s or 200`s mains are going to work for you sir. 370 maybe 380`s
