    now, i really DO NOT care if anyone disbelieves me.

    this is a true total: between 16,000 and 18,000 miles on the very first motor ive had. a kingsmotorbikes 70cc.
    this has been ridden, and is still being used to/from work daily for 4 years. until 6 months ago, i lived in tucson, so 'winter' was still 75 degrees.
    only once or twice a month, did i use the car.

    16,000 is true, calculated miles to/from work. but i guessed another 2,000miles for weekend riding/errands, etc.

    its unheard of. even a well-kept motor doesnt usually last much more than 10,000miles.

    replaced a few cdi boxes, a few carb needles, tons of spark plugs, a magneto, and replaced head/jug gaskets.

    Is this something I should be worried about enough to carry a spare?

    Yeah, how much of that did you have to do on the road?

    Why would anyone not believe you!

    From your description, your engine may have roughly 1000 hours of use on it, which isn't an impossible feat from a two stroke engine with hard plated cylinder that was tuned properly and run well within its limits. An old boat of mine logged 1200 hours on a two stroke outboard, with many of those hours spent with the throttle wide open. It was still running strong when I sold it for a bigger boat.

    While these imported engine kits may not have a very pretty finish because of the casting method, the bores are usually nicely chrome plated and honed, and have a good fit with the piston - which looks like a decent quality casting and alloy. I think it is because of this hard chrome plating that it takes so long for the engine to fully break-in and perform its best. For me, it seems like power and compression aren't at their best until you have about 25 hours of running time.

    I miss the old kingsmotorbike engines. I never had one as long as you did to know how long they lasted but I can say they were the most powerful Happy Time engine I ever owned. I could climb a steep hill with a 44 tooth sprocket at decent speeds. The newer engines can't do it as well (fast) with a shifter kit with 7 gears to chose from.

    are you ever scared of hitting the "reset" button and losing your mileage record!?!?

    All of the computers I've seen will allow you to set the odometer so you don't lose your mileage in the event you have to change your battery.

    I've got almost 4k on this engine (approx 1 year old)
    never babied...ran hard from day one...I work it hard pulling the girls
    never had any probs till about a month ago...seal leaking causing clutch slippage
    much adjusting since it started
    this is a 100$ replacement engine from livefast
    I calculate 2.5cents per mile ownership cost (minus fuel)...can't beat that anywhere else

    should have some really good news this week :):):)

    I'm guessing you are becoming an EZM dealer and you are getting your kit?

    haha. it was more of a "i refuse to run at less than 1/3 throttle, even with new carb, plug, magneto, CDI...anything"

    really. tried all new components and yet it just wont stay running unless i'm on the gas. not much for that wonderful power it had, either.

    no complaints. 4 years and around 15,000miles. not bad. not bad at all

    Sounds like it is just plain worn out.

    If the bore looks like the plating isn't flaking off, hone it and buy a new piston/ring set. You might get some more miles out of it! I think you have the record for HT engine longevity!

    i didnt know you could hone it, seeing its a Nikasil lining and not steel-sleeved. but i got nothing to lose, so i'll try it. whats the worst that could happen...i mess it up? :ack2:
