ProDigit, two questions, I see from above what tire pressure you’ve been running, what is the maximum pressure stated on the side of your tire? That’s question 1 because my Hawk 250 DLX manual calls for 40 psi on the rear tire and the tire itself says 32 psi max. I do believe the manual may be incorrect. Second, your post above you use 0.04-0.05” I’m sure you meant.004-.005” right? If you changed the intake to .002” it would be quieter and cooler, I agree. Was looking at your thread and sounds like your having fun with the bike. My thoughts
