Re: Big Bore with stock Intake and exhaust?

funny how I have had the opposite reactions. ive ran many of stock or ported intakes and carbs with bigger jets. but have had terrible luck with stock exhausts. they overheat or strain the engines. after I build a big bore motor. first upgrade is to up jet. next is a new exhaust.

Re: Honda gyro Leaking Oil

ive seen people have good success with a soldering iron and metal wire mesh. the key is to only heat the surface. heating the whole piece all the way through distorts the panel

Re: Honda gyro Leaking Oil

if you cover exhaust and it still runs, that is the sign of an exhaust leak. that would also drop you top speed.
on the gyro, just make sure you close petcock after use. see if your issue persists. do you live in cali? what city? I stay in whittier.

Re: elite 125 ignition switch on my aero 50 issues

if you have a test light or volt meter. you can troubleshoot it. if not its gonna be trial and error. the scooter wires is what you fork from. red is battery, black is switched power, green is ground, and black with a yellow stripe I believe that's the colors, is the ignition kill wire. key on= conn...

Re: Honda gyro Leaking Oil

ive torn into a few of these motors. 2 of them down to case halves. the 2 strike oil pump goes into the gear case portion of the engine. not the crankcase part. I still don't understand what builds pressure in the gear case portion other than heat from the clutches and gears meshing. thr crankcase a...

Re: AF05e Wont Stay Running

if you need something to clear the small ports on your carb, I like using a bicycle brake cable. fray out the end and pick the biggest strand that will fit in the port/hole/tube you are trying to clean. you can even use 2-3 twisted back together. I save old brake cables just for carb cleaning. fun f...

Re: 89 Honda Elite LX fuel leak

That explains why it is leaking, partially. The fuel petcock is definitely broken. Replace it. In conjunction, the float needle ALSO is suspect. Even when the the petcock flows without engine running, the float needle SHOULD stop that flow. I agree with Mike 1000% you have 2 issues petcock stuck op...

Re: HOW TO: Convert 1985+ NB50 to Disk Brakes

I thought I posted pics of the caged bearings but I didn't, I'm gonna make a parts list at the end cool. the caged bearings are so much nicer to keep track of than 36 individual ball bearings. I think you and I had talked about the bearings in text. but I didn't see it here so I thought id add it. ...

Re: HOW TO: Convert 1985+ NB50 to Disk Brakes

another thing to add to this is the zx and other japan scooters have the neck bearings caged. not loose like our us scooters. the caged neck bearing will fit in our US cups and work just fine. and theyre easier to keep track of than the loose ball bearings.

Re: opinions on best variated AF05e big bore kit

the metrakit and the zeta racing kits are my favorite kits so far. the polini is a good kit but the 9800 rpm is a bummer. and that's after 2 gaskets. I might try to raise the exhaust a mm when I get some time and see if that helps anything. I also want to put a 90/90 on it cause currenyly I only hav...

Re: 84 nb50 aero outer variator sheave ideas needed

ive swapped them all around just to see whats up. I swapped a variated af05e into my chopper spree and wasn't happy with its performance. thought there should have been more. I noticed them all having different part numbers. except the 84-85 nq50 was the same and 86-87 nq50 had another #. and 84nn50...

Re: 84 nb50 aero outer variator sheave ideas needed

lol. watch, the first gen cdi is faster then the rest. close second is the nn50 gyro. the second gen aero cdi doesn't like advancing the timing at the flywheel. the first gen can take a good amount of advancement with no issues for me. engine wise, the ab07 likes the advancement more than the af05e ...
