I have been at this for a little bit have seen some tips on upgrading the engines from drilling out jets to the next level exhaust. I was wondering what works not like the nitrous that's just dump. i hear alot on the boost bottles and the reed valves post your best upgrades here!

I'm always touting the billet intake-
you just missed the President's sale at Bikeberry where it was going for just over ten dollars-
getting the carb close up to the cylinder seems to make all the difference in carburetion, and for the most modest cost.
The NT 66 carb with a 66 motor also helps performance, but not so drastic and at more cost.
not a motor upgrade, but the more narrow the tire, the better the roll
and a 36 sprocket works well, on the road at least
