What would be better a Tanka 47R or a pocket bike engine?
Tanka 42cc produces 2.8 HP Horse Power as advertised.
How many horsepower is a pocketbike engine? 2.6HP, 3.1HP, or more/ other?
I ran a custom-built pocketbike engine that supposedly had 10 hp. However, on its maiden voyage, the engine stalled. I could never get it to start, even after 100 pulls. Strangely, the engine does not have a keyway on the coil side.
And so it sits on my shelf, until I find out why it doesn't work.
Now I run a new 2.8 hp Tanaka 47R engine with the engine-specific Tanaka three-piece power pipe. It is center-mounted with Scooterguy brackets. I was able to fit the pipe AND OEM muffler on my bike without cutting or bending anything.
JMO, there IS no better engine for a motorized bicycle, provided it's hooked up to a low-geared shift kit. The 47R is a high-rpm racing Powerkart engine that loves to spin well past its redline. If I drive like I stole it, I get home fast at 88mpg. If I drive below its advertised 7,000rpm redline, I get over 100mpg with less oil spray on the bike and the rider.
A gallon of 87 octane gets me to and from work for nine days. The 47R is a loud pig with a voracious appetite. However, with a pipe and a shift kit, it's a tamed beast and sips on gas.
The spare 47R engine is much faster because it's ported, but I like the new one better. It has less than 2,000 miles on it, and has NEVER given me problems.
I'm tempted to buy the Tanaka 3300 engine. It's a steal, but I have no use for it. If I want less power and more mileage, I could always bolt on one of my 2.2hp Mitsubishi TLE43 engines.
If I wanted MORE power, I could always reinstall my 4.5hp GP460 engine and HT expansion pipe (But then, I'd be forever worrying about its clutch issues, lol).
