5 weeks during the cold winter is not too long of a wait but would be bothersome in the summer....
I'm going to talk to Bullet Fabrication 3103273777 about it.
CFM should look into doing it since they already fabricate an aftermarket air box & oil tank.

 

I run a +4 swingarm on "TUNED" raptor and with some track conditions it feels a little too long and other times it feels a little too short. You need to find a happy medium and +4 works good on this inparticular machine.
