Hi Nate, it’s been awhile since the fabrizi pipe has been mentioned but I seem to recall it was designed to pair up with the fabrizi 82cc bbk and I have heard mention of older 90cc fabrizi bbk but either way, those fabrizi exhaust ports were huge! And possibly your corsa does not pair perfectly with that pipe? It could be all in the tuning as well, but I wanted to throw that bit of info out there. Let’s see if anyone is still around who has experience or an educated opinion.
So quick update on Mr. Scooty.
I switched down to a 40 Pilot, and it is like 7/8 turn out, I probably need 42. Either way it runs fine and cool with the 40 and the 45, but will run screwed in on the 40 so I know its a smidge lean.
I tried to ride it around when I changed it, but then noticed i couldnt accelerate, I thought my flywheel was loose again, but turned out that the resistor for the plug wire was smashing into the frame and it broke apart.
New NGK plug and wire is much nicer quality and lower profile.
I also found that the pipe was blowing oil on the frame seemingly from the exhaust stud this time. That seemed weird, turned out that when I tried the stock Polini gasket and tightened it down, it broke the weld on the inlet and it was bouncing off the stud into the frame.
I had my friend reweld the pipe and press my 15x42 gears in.
I decided to buy a Yellow Malossi Contra as well. I have a 1k NCY in there but I was told I probably should use a little stronger.
Also got a new polini belt around the time i switched my pilot, and got it mostly shimmed.
So with fixed pipe, new gears, stiffer contra, swapped in met rear wheel, the bike was finally seeming reliable.
I took it for a 20mile round trip ride to the climbing gym since it was warm. Temps stayed under 300 degrees the whole time, even with spurts of WOT. I didnt GPS it, but the bike seems to keep pulling at any point I wanted. Esp on teh top end. Above 40 you can feel it pull if you open it up.
It seems to stay on the pipe a little better now. As far as I can tell it hovers at around 10500RPM.
I took it on another ride for lunch the other day too, this time about 30 miles of riding round trip. Sadly the hotdog place was closed for holidays, but I got some reliable rips on the bike. It feels strong, runs cool and seems to be powerful. I am wondering if the low revs are related to variator weights or if its possibly just too rich and not making as much power as it should. I am getting some oil out of the pipe so maybe? I might try leaning out the MJ a little in the coming days.
I was getting some breakup at mid throttle, I moved for leaning out the needle a bit, and now im running second from the top of the needle instead of middle which was stock. That seemed to help but it might need a little more adjustment
Tried getting the stock aero panels back on, left side fits, right side the glove box needs more cutting and the bottom part of the panel hits the fabrizi bad. Normally I wouldnt cut it, but they are pretty junked up as is.
I think I have about 4.5 hours on the bike now. It feels more reliable, broke a spring on the stinger, but thats pretty minor.
Also I bought a met stem for super cheap that im going to poke at, but the drums are feeling a little better with wear-in.
I dont think I would go taller gears either, the amount of acceleration is great, even up hills it chews them like a billygoat but doesnt seem to wanna wheelie too bad.
