An old saying goes, "You can have two qualities of power, reliability and low cost, but not all three".Ok. I was just worrying about getting a pocket bike engine once I saw that tempting deal in the other thread.
Felt like I could have spent the same amount for more reliability. But for the same price I guess it's either power or reliability, it's a choice.
Yes, my 47R was ported by someone for great performance.Now I can't afford a good deal anymore lol.
The Tanaka 47R is 2.8 HP which is still less than a pocket bike engine.
Or is the tanaka custom ported by someone for max performance?
They're hard to find used.
This looks like true performance to me with a tanaka 40cc engine (maybe because he's going downhill?), but he seems to have a custom ported cylinder and cut piston for max performance and other parts and lots of money invested in it:

Horsepower is just a number I TRY not to get excited about. Now GEARING is where the performance is! I am totally excited shifting through the cassette. I usually only use first, third and fifth gears. If fifth gear is buzzing the engine at 35mph, I'll shift to 6th gear, which is 16.36:1How many horsepower does your ported Tanaka achieve?
How much did it cost you to have it ported?
A used Ported Tanaka for $120? Temping.... I doubt anyone else would sell it for that low lol.
The pocket bike engine can also be custom ported: In pocket bike parts this member named Boosted does custom ports to get TRUE performance gains. It's amazing how he ports them, but it costs like $80 to have him port an engine.
Search gopednation.comIs there any big difference though?
Does it revv higher?
You bought it used for 120?! Hmm where can I find a deal like that.
