I think some of the best key things you can do to this bike involve the carb - including a new trick developed from the Dirt trackers for carbs - if you up your Blasts power delivery - enough umph - then you end up working from quarter throttle for a lot of your in city stuff, so then you want to increase your quarter throttle response ability -
This is suposed to do just that with no negatives to the top end - I'm thinking about mounting one in the stack extending into the carb - you can do a lot even to a stocker to increase throttle response.
EZ's Stock bike Mods:
1)Drill a 1 1/2" hole directly across from the first hole of the stock exhaust on the same side as the stock hole but all the way to the right of it.
2)Rejet 45/170 (some years will have 170 stock - some don't)
3)Shim needle to 0.05 - 2 #6 machined brass washers is close.
4)Do the air box - mild or wild - still keeping the basic look though.
5)Drill air-screw plug out, and bottom screw then turn 2 1/2 turns out.
6)Do primary adjustment - preferably sound method.
