I also ran it with one shim under the needle and it ran very rich to the point where I had to remove and clean the spark plugs after about 500km. It started running like crap. Removing the shim brought stuff back to normal. Mine uses stock 108

No other modifications are made, stock airbox , stock exhaust
Cool, thanks for the data!
