Helping a buddy of mine we came across his 82 Honda Urban Express NU50i. He rode it around Iowa City while attending college and it had basically been forgotten about. 2006 tag. Took it as "payment" and with my "FREE" noped I opened the can of worms and started "investing". Non running I cleaned the hell out of the carb and followed Freds guide. Got it running a stock 27 mph. Put the level 2 kit on and was running a zippy WOT 35 mph ALL DAY!, ALL DAY!
Removed the 3 worst looking weights for some small gains. Running 6 x 8 gram weights helped but I still need to swap 3 - 8 gram weights for 3 - 4 gram weights looking at 36 grams total (forgot my impact at work).
Replaced the BX31 for the Malossi and followed the wiki to convert the carb to accept Uni filter foam.
Installed the peoples side bleed pipe and my WOT acceleration took a massive dive but feathering the throttle I can accelerate and reach top speeds up into the 45+ mph range. Still need to GPS it but the pipe took top end to a whole nother level.
At this point I feel like my gearing is the only thing holding me back. I have the new clutch installed with the yellow contra spring but I feel like it's still not right. Might have gotten the wrong combo. Please advise me on my next step.
