Honda Spree and Elite 50 Forums

there ARE actual high(er) performance or "racing" fans that are made for the AF05 engine, AF16, etc. -i know because i have one!! Be careful of what you buy, a lot of us have been turning wrenches on Honda (and their clones) mopeds for over 15 years and we have yet to find one better than...

I wouldn't use seafoam on a moped engine. On my dirt bikes it makes some sense since they have powervalves. Castor oils leave varnish behind when it is overheated, and it might cause some problems with the power valve especially if the rider doesn't know how to jet on the mark. Varnish is fine on a ...

You could try and go with stronger clutch springs but there is a hit and miss possibility that it might not work out as intended. The idea is to tune the clutch engagement right when the pipe generates backpressure (harmonic resonance) to produce power. - If the clutch engages before that point, it'...

808BMW's correct, those green and pink fans are garbage and annoying noise makers. Unless your bike is going to remain stock, stay away from them. I would normally start with a 7 or 8 (NGK scale) heat range first and see how it goes. On a normal, near stock bike without any custom porting, a 7 range...

Greetings: So Flash II's now running with a high-compression Malossi 47mm/65cc - installed sans gaskets thanks to ScooterWerx's skillful O-Ringing. Also plugged in my own version of Werx's design of SE/SA reed port adaptor, permitting me to install Toasty's tasty CT manifold, which in turn opened u...

Daytona rollers aren't cheap as they go for about 15 dollars for a pack of 3. If/when you decide to use them, make sure you're done "dialing in" your variator.

I personally have a set of semi-crappy rollers to use to find the right setting, then finalize the job with Daytona rollers.

The multipack I use aren't Koso but it's some Chinese/Taiwanese brand though. Daytona brand rollers are the best from what I've seen as nothing seem to outlast them and they're coated with some plastic/teflon. If your rollers got chewed up that much the quality of your variator and/or ramp plate mus...

They look really comfortable to ride on based on the rider's position. Sometimes it's not all about the speed and how much modding you can do to it.

The Trailtech is one helluva nice unit, I have 1 installed on my old 250 dirt bike and I love it. Good luck with your install Toast.

Well Polini claims 11hp from a Corsa bore too. I wish I could gain that much power from a 50cc to 72cc upgrade simply by installing their bore kit. I understand what you're trying to say but if you go around to moped or dirt bike tuner shops and associate power increase with reeds, they'll think you...

So then, what are the pros and cons? What are the disadvantages of going to different types? One of the kits on eBay have two different reeds, one for street and other for racing. $30? I would spend that for a little more torque throughout and less floating at high RPM, especially on the SB50. Torq...

Where are they doing business from, Europe? When I deal with overseas products, I most certainly ask for a shipping method that involves tracking, even if the cost comes at my expense. If they sent the products using a non-trackable delivery method, that's not very smart. I wouldn't have responded t...

For those careless (or simply unfamiliar) with removing the fuel bowl of an OKO or Keihin PWK carb, they might tweak the float by torquing it, bending it out of shape. This occurs often when someone tries to remove the fuel bowl while the carb is right side up. This has the effect of either placing ...

Reeds are a component that sometimes mimics the effects of carb tuning (via jetting). The basic idea behind the reed's function is no different from a check valve which allows flow while the piston is on its downward stroke and stops incoming flow when the piston is on its upward stroke. Reeds move ...

AF16E engine (DIO), stroker configuration on parts.
