Need an idea where to start with my main jet. Top end still being broken in and I haven't really hit the main yet but will be doing so now.

Lrd adjustable, (adjusted about in the middle)
Uni filter
No air box lid ,Airbox lid cover is an outerwear
About 500' elevation
Temps are in 40s during riding time
Stock carb for now until break in is complete (Going to a 28mm,,, I'll deal with that jetting later after break in)
Agressive trail Porting and head rechamber
Running oil injection
Boyesen RAD valve

300 310?? Bigger?? I have no idea with an Lrd..
 
I ran a 330 with the LRD adjustable I had, adjusted as short as possible, on a stock engine/carb, VF reeds open airbox, UNI filter, 32:1 premix,
@ 1800' elevation, in summer temps.
I'm sure that 330 was rich as i ran it in cooler temps too, but never fouled a plug.

I'd say richer for you @ the current temps and lower elevation, but you could start around the 330

Thanks fellas. I'm going to start with a 330 and see how it goes. I'd rather be rich if anything.
