Carb Cleaning
Greetings: There's no way to tell how good/poor a job the P.O. did on your carb. Gas is "clean" going through the filter but the carb (and its very tiny passages) can gum up from evaporation if it sits for a while. The volatile parts of the gasoline evaporate out leaving a coating of solid...

Various Variators
Greetings:
It's helpful to specify your model/year. I will install the Keli on my '87 Aero this week and will report on the process and performance.

Underclearanced Oversize?
Greetings: The dimensions of the piston and cylinder are a critical measure to some people. I'm not entirely sure if "mildly ... honing the cylinder out a little..." is sufficient to make room for that "minor difference" of .001 bigger piston. Honda-san's Service manual specifies...

Oil/Gas Ratio & Big Bore
Greetings: The unproven assumption - that increasing the piston diameter from 41 to 47 requires more oil to be injected - has been asserted. The ratio is fixed if you eliminate the pump and premix the fuel in the tank. Otherwise, unless it's adjusted the pump will deliver the same amount of oil to t...

Polini 47 mm Piston/Cylinder Kit for NB50/SE50 & Compres
Greetings:
This kit uses the stock head. How does the kit compensate for the resultant increase in compression ratio? Less dome on the piston? I'd rather not wear the head in my crotch...

Oil Pump Anatomy
Greetings: Scooterwerx said he'd "fudged" his pump attempting to disassemble/inspect it. (Despite Honda-san's stern warning "do not attempt to dismantle.... said pump.) What did you learn? Has anyone else tried to do this, and what did you discover? The Service Manual is no help at al...

The Enigmatic Oil Pump
Greetings: Aside from the vicious interpersonal attacks, here's what I've learned so far: 1. The NB50 Aeros built after 1985 had throttle-controlled oil pumps. The pump is geared to the crank , so it IS RPM-sensitive, as well as responding to increased lube demand occasioned by opening the throttle....

Premix Apocalypse
Greetings: I respect your opinions. Race tuners usually know. Discussion points: Round town riding differs from racing considerably. A fixed rate of oil delivery won't correspond to varying lubrication needs like a throttle- controlled pump. Fouled plugs are cheap but changing them by the side of th...

Clankage
Greetings: So it clanks under load only? Slap is possible. Ask why. Poor fit in cylinder perhaps? Hope not. Ping or detonation from bad gasoline? Try a tank of premium? Too-early timing can cause ping but static timing is reportedly non-adjustable, so not likely. Excessive compression from carbon bu...

Grease 'Er Up!
Yes, your displacement increased but only a tiny fraction. Same jets. Better too much oil than too little.

Design Limits

DIO-Log

Language differences are studied and Marketing department focus groups dictate what brand name increases the chance for success. Or failure, in the case of the Chevy Nova.
