How many miles are on your happy time?

[TWalker]

I bought my first one 3 years ago from Kings and it is by far the best, smoothest running engine I have ever had. I wished all my engines had been this good. The chinese quality fade has nearly forced me away from using them at all.

No idea how many miles probably less than 1,000 but it has served me long and well and is getting a sick shifter this week.

This was the first bike and engine I built.

I'll be honest, a Kingsmotorbike engine was my favorite all time engine. It was indestructible and I abused it a bunch running nitromethane/methanol in it lugging up steep mountain passes for hours at a time...to the point that the exhaust turned cherry head and the head changed color from the heat.

I put hundreds and hundreds of miles on the bike mainly on offroad trails in very poor conditions. It never skippeda beat. I sold the bike last year and haven't gotten one like it. It was by far the most powerful HT engine I have ever owned to date. Unlike today's engines, I used a standard 44 tooth sprocket to mountain climb. Every motor since then is a 48 or 50 tooth sprocket because they don't have the torque to climb hills at respectable speeds.

I don't know if Kings even sell's the same type of engine today. I screwed up and bought from almost every other vendor since then because of price and convenience. I wish I had dozens more like it....a powerful bushing engine that I never worried about.

I agree, I think I bought mine while the chinese were still wanting to impress the US market to buy engines.

I've had some decent ones since but none that had a smooth power band and were indestructible like this one.

Its a keeper.

220 miles on my Powerking 80cc

87 octane

20:1 mix - Amsoil Interceptor - no problems at all. Starts every time.

Normal speed 20-22mph.

Once in awhile, I will take it to 30mph for a few seconds - It will do that easy, so once I get some real miles on it, I would be curious to see if it will get to 35mph or higher - again for just a few seconds.

44 tooth. -I live on steep hills so I need pedal assist to get up the hills at WOT at 22mph.
May go to a 50 tooth, but I don't want to sacrifice the top speed yet. And w/ the assist, it doesn't really seem to be putting a strain on the engine.

I would be curious to know if anyone else has an 80cc w/ a 50 tooth, and how that works for you?
But please answer the primary question for this thread. I don't want to be accused of thread stealing.

my Dog: - (still under construction)

no problem,s at all untill i went to a cheaper oil that i wanted to get rid off then the bushing fell apart.chunks went up the port got lodged in the piston side and took out the cilyinder.

I'm just getting started breaking in my king's 80cc. So far, I'm impressed. Runs great, idles well. I'm breaking in at 16:1. Any reason you wouldn't want to keep it as oily as possible? What would be wrong with running at 16:1 all the time? My plug looks great, and it has reasonable power.

I think oil is your friend with these things. And keep the rpms down. The buzz is pretty intense on the upper rpm ranges. When it's vibrating, it's tearing itself apart, and cracking your frame.

I don't see any reason why it would hurt anything running it 16:1. I run mine 20:1 all the time.

I just rolled over 3,000 miles today!

900 miles on PK 80cc. I ride with wide open throttle about half the time especially on the freeway. Max speed is about 30 mph. I also rode wide open throttle up a 9% grade for about 8 miles at about 15 to 20 mph with some peddle assist when the grade was steeper and at 12 to 15 mph during the pre-300 mile break in period.

Also I rode between 30 to 60 miles a day during break in.

Only problem so far is that the muffler broke off at the weld yesterday.. Will take to muffler shop to fix soon.
