Hey, so I have a 2006 Yamaha blaster. At the moment it has vforce 4 reeds, and full Fmf exhaust pipe. Recently I just blew it up from running too lean. I had it running great before temperature dropped, so I’m guessing I’m gonna need to rejet it for the weather, what should I be running?
What jets should I run for colder weather?

As a general rule. You should go up 1 size for every 30 degrees of temperature drop. For example FMF pipe with open air box and stock Mikuni carb at 80 degrees, at sea level wants a 280 main. Everything the same but drop temp to 50 degrees, you should go up to a 290 main jet.
