Engine break in?

The shitty design of how the stock filter is "supposed" to seal up to the air box failed.. It ran great for a little while then just lost all power and i took the seat off and looked at the air filter and it completely came undone and the motor was sucking ungodly amount of air with the stock jets of course. Started the tear down about an hour later.

 

Yep, it leaned out and fried the top end.

Tear those carbs down and clean them out with carb cleaner and blow them out with compressed air!

 

Do you still have TORS?

Hey Jacowils......to be honest.....being on the stock porting....with the pods, head and fatties i'd bet its going to be around a 290 for summer here.  That being said....a lot of the builders here will tell you that its roughly every 20* that will require a jetting change.  So say if your going from being jetted for 80* and suddenly decide to ride and its 40* out........it should require approximately 2 mains larger to compensate for the cold air. 

 

With the boysen reeds, id suggest probably jumping up to a 27.5 pilot.  

 

But with your mains.....you wont need a larger than a 320......hell im running a 330 with fmf fatties, k&n pods, 20cc domes, vf 2 reeds, and a dune/play port from FAST.

 

Where are you at here in Michigan?

I already swapped out the stock pilots for 27.5's and put the needle on the 4th clip. I just went nuts i guess and bought too many sizes but oh well there only a couple bucks a piece. Im think i should be safe with some 320's for the break in until i can do a plug chop, but i also dont wanna gunk it up so the rings dont seat properly.. And im in flushing located about 20 mins west of flint
