Re: Stock dd50, curious, newb builder.

Greetings: Not sure what the rules are in Hawai'i for "Safety", but it's unlikely that the inspectors will pull a head to measure piston diameter. Just don't get ticketed for doing 65MPH on a "50cc" scooter, which a well-tuned modified DD is quite capable of achieving. Modding is fun - well for some...

Re: Af16 Assistance / Build

Greetings:

Very painstaking careful work Nate!
See if there's a way to fabricate a bracket to support the weight of that big carb. I have READ (No direct experience) that those rubber carb flanges can fatigue and crack, letting air in.

Re: 2-stroke resurgence!

Greetings: Very businesslike. You can bet with all the top-shelf carbon exotica it won't be cheap. Microprocessor-controlled direct injection meters fuel to near-perfection, reducing Hydrocarbon emissions. I'll bet it has a recirculating lubrication system too. But will it retain that intoxicating 2...

Re: Idle issues and unresponsive throttle Sb50p

Greetings:

It sounds like the engine is sucking a substantial amount of air from someplace. Carb/manifold seal and many, many other places need to be examined.

Re: 1985 iowa honda spree and new member. Need help please.

Greetings:

Low compression may or may not be due to rings. Check both crsnk seals and do compression test with reeds on and well-sealed and carb removed or throttle wide open. If still low, post WTB for a stock cylinder . People take them off when installing big bore kits....

Re: Af16 Assistance / Build

Greetings: Polini contessa is a good kit. No need for gears shorter than 9:1, even a stock 50cc can pull those over 45MPH. Mine with stock carb And exhaust will do 50 upwind all day. Welcome to the madness. BTW sometimes seals fail because they are old. Sometimes it is a bad bearing or wobbly crank....

Re: 87’ Elite variator Clutch Tuning

Greetings:

It is great fun! Your plan to replace every other 7g with an 8g is sound. Make changes of 2-3 grams TOTAL LOAD at a time so you don't overshoot.

I bought a cheap one from Amazon or fEeBaY or someplace, around $25, worked great. Even came with stick-on gram weights.

Re: jetting a se50

Greetings: The REAR ZX pulley fits the clutch shaft just fine, but the wider belt requires 2.5 mm more space between the variator and the outer pulley sheave. Here is the problem; the skinnier AF05 crank. The splines aren't long enough the engage the outer sheave properly. I recall someone here post...

Re: Wire starts smoking

Greetings: The starter circuit is a high-amperage affair. You may have noticed the wires are bigger in gauge (10?) than the other scooter circuits. A non-stock, thinner wire replacement will overheat and burn quickly - make sure the wire gauge is stock. If not the wire, make sure the connections are...

Re: Stripped spark plug hole

Greetings: Most of us have gotten in a hurry and cross-threaded something. Lots of Forum members have opted for the big-bore option on their Sprees. Good used heads are cheap and easy to find. You might have to remove all the plastics to get the cooling shrouds off and get to the head. Another optio...

Re: Flash 9: Sanity Restored

Greetings: Been so long... no longer exactly sure. Mid-stiffness spring - I came up with a way to compare springs using a bathroom scale and a defined compression distance. Variator load feels like it's about 3 grams too light. Engine winds up higher, then settles down to torque peak, losing a half-...

Re: NB50 Front tire mod

Greetings:

'85 had the 2-bolt intake and no kickstarter, but otherwise the same as '86 and '87. Gearing was 11:1, like the earlier Aeros. Coveted '87 Elite S 10:1s are very hard to find.

Re: NB50 Front tire mod

Greetings

I ran Met wheels and 90/90s front and rear on my '87 Aero. The centerstand will need modification to clear the back tire, and the front will kiss the fender over curb cuts, but otherwise it's fine.
