It's another ~40cc bump. I do miss the arm ripping power of my KTM 640 at times. Never liked that much torque (or weight) in the woods but on the roads it's a dream.

 

If you already have the 300R cylinder then you should be able to send it to mark and get it done for that $400 price, that's a deal if you ask me.... Bore,replate and new piston/rings

Edit, woops s10 already said that

 

I use to go 83miles before I had to switch to reserve. (stock snorkel DJ120main 38 pilot 3rd clip). Now at the level of the tank looks I will be switching to reserve at 70 miles. (KDX snorkel DJ132main 38 pilot 3rd clip).

She runs so nice and smooth I am OK with that. The extra power just makes this bike so enjoyable to ride.

 

I went from about 60mpg to 51(ish) with the 330... If i can stop trying to pull wheelies and doing WOT runs maybe it will improve a bit. Even 50mpg is still 125 miles till reserve with the IMS tank.

 

Stop wheelies....lol good luck with that.

I just may get a IMS tank myself.

 

You won't regret it.
