The Dellorto carb real or fake run rich on the top end and is too lean in the mid to low range. More so with the fake. I like the NT but have had good results with the fake Dellorto once I drill a extra hole in the tube. The slide cut away also affects the low and mid, Jag has much info on this, do a search. I also put a o ring in all the carbs I use.

Fake D Carb Drilled.

I like the carb, but curious if you've done any other performance mods. I'm fairly certain the pipe performs better than stock but isn't the best for a 2 stroke. I've been wondering if the bt80 can really be brought to life with reed valves, a tuned expansion chamber, modified timing and port work. How is vibrations compared to an unbalanced china girl? Wish the head was removable from the cylinder, would open more doors to get more power.
