    Thought it would be a good idea to start a thread about how long you guys have been running your kits,,how many miles do you have on your motorized bicycle,,and how much did you have to repair during the period.Can we see a 10k mile motorized bicycle possibly,,that would be fantastic,,especially on the same engine!

    Thanks guys!

    It's an often asked question and you'll get some replys. It never hurts to ask questions again because newer members might not have seen these older threads dealing with the same subject. The 10k figure has been posted here several times by some of our members.

    I'll chime in first. All of my current bikes except for one I just built over the winter have over or near 1K. One has over 2 thousand miles. Maybe I've been lucky. I've only experienced minor problems and have never had a major issue with an engine. I don't abuse my engines but they do get ridden hard occasionally, and put away wet :)

    Been riding for two years now and have around 4000 miles. The Robin Subaru EHO 35 still works great. Change oil every 50 hours and clean air filter every 10 hours, they'll last forever. About the only thing you'll have to replace is the sparkplug.

    With these bikes breakdowns do occur. As you learn more about your bike better ways of doing things become clear. I consider this a good thing in that it challenges you to always want to improve your bike. Meaning you don't become bored and lose interest.

    The bike also puts me into a family of other fellow bikers here on the forum. I enjoy sharing my love of motorized biking with others who have the same passion. In my public life people are always wanting to talk with me about my bike. So for whatever it takes in repairs and upgrades it gives back so much more.

    I've completely lost track of how many miles my Pig has on it. Still runs great! No failures of any kind. I did have to drain the tank once due to water in the fuel but other than that, it has been bulletproof. I have not had anything loosen up or need adjustment in months. I'm on my fourth set of brake pads, my 7th back tire, and my 3rd front tire. The HD#40 roller chain was the best $20 bucks I ever spent.

    I also replaced the stock plugwire with one I got while at a local pull-a-part yard. I only needed one end so it was free. (Best kind of upgrade!)

    I just unscrewed the stock wire and replaced it. I hear some kits are glued and you have to dig it out, but it is still a great mod even if it's glued.
    The HD chain is the first mod any motorized bike needs.
    Makes it so much more reliable, less drag and noise as well (depending on your particular tensioner setup)

    I think the motor will last longer than the bicycle.

    Here's my solution to an oval tube mount. Long bolts screwed into the mount with coupling nuts to tighten. No cutting required (although it would be easy to grind the heads off the boltsfor a more sanitary look)

    Here's a better view of the latest pipe

    Has a nice sound and good torque, with a nice sweet spot right at my normal cruising speed. I also run a 41 tooth sprocket to drop rpm's a bit.

    My Schwinn AluminumComp Mountain Bike with a generic 66cc in-frame kit lasted me well over 10,000 miles as an all season daily driver/commuter - but I'll not deny that longevity had far more to do with random chance then anything in particular that I did or the type/brand of motor & it had it's fair share of issues, mostly gasket related;

    [​IMG] [​IMG] [​IMG] [​IMG]

    Funny you should say that lol, while the frame is still in great condition - the bike was retired from service shortly after that last pic was taken. While it still ran great, the compression was a bit low & the chrome cylinder liner was beginning to flake a bit (bottom of cyl) - it was really just about everything else other than the frame & motor that was done for, beaten, corroded & just plain tired I realized that the cost of repairing all of the bikes woes, pretty much everything other than the frame & motor would cost more than just building a new one, even including an engine.

    Primary cause of destruction? The salt & calcium chloride they put on the roads around here in the snowy season and my indifference - it was a $400 beater built specifically for that abuse ;)

    my first engine, a grubee starfire gt4 lasted well over 10k. i rode as my primary means of travel almost everyday for 3 years, raced it twice, and beat the heck out of it

    the only problems were 3 busted chains and one cdi failure.

    one of the busted chains cracked the case so i had to replace one side, but that wasn't the motor's fault.

    there's almost no chrome left on the cylinder walls, but it still ran great.

    i actually still have that motor, but i grinded away on the motor mounts to fit it into my little red racer so i can't put it into another bike without welding some mounting tabs on the frame.

    the motor i replaced it with when i rebuilt the cruiser has a couple thousand on it with no major problems.

    but, i also have a junkpile of broken motors that i raced with. some of them lasted a few hundred track miles, one lasted 10 street miles, and another new one that i spent a week on to make it go fast made it almost to the liquor store 5 blocks away before the stock crank bearing (the only thing i didn't replace because they didn't have them in stock at my bearing place) disintegrated, destroying the rest of my hard work.

    My first engine is on its second bike. The original "Tempus" - a Micargi Huntington - was in a bad wreck with an F150. Frame was bent and cracked. The float bowl of the carb got cracked also. But I went over the rest of the engine with everything short of a microscope. It was fine. New carb did the trick.
    It is now bolted to the JC Higgins in my avatar. I haven't had a speedo hooked up to it in more than a couple years so I don't have a clue how many miles. But the engine's been running fine since early 2010, so at least three years of running like new.

    First bike is a China Girl and made it about half a mile.
    Took a month to get it replaced. That engine lasted about 300 miles and then ground out the crank bearings. I will likely replace the engine when the snow is gone.
    Second bike is another China Girl and ran great for another 300 miles and then broke a front motor mount stud. It is still running good; just not rideable. I will replace the mount studs when the snow is gone and keep at it.
    Third bike is a 212cc Predator build that I am just starting.
