    *** SOLD ***
    This is a serious, high performance engine that was built a couple of years ago by Terry @ Fire Power Minis.

    Quick Specs:
    • 195cc
    • 12:1 Compression

    He started with a YX160 and added the following
    • TB V2 Race head
    • Takegawa S15D de-comp cam
    • TB 66mm cylinder (195cc)
    • 66mm Akunar Piston.
    • Keihin PE28 Carb jetted for the above engine

    I bought this engine on a street-titled Honda CT70. This bike could accelerate quickly to 70 MPH! 70 MPH on a CT70 is a bit on the scary side, but, fun. I have since injured my back and can no longer kick start a high compressing engine.

    I have since removed the engine and sold the rolling chassis to a friend who had another engine he wanted to put on it.
    Now, this great engine is up for sale.

    Included with this sale:
    • 195cc YX160 engine as described above
    • lighting coil (not sure specs)
    • Keihin PE28 carburetor
    • Flywheel
    • Shift lever
    • Kickstarter lever

    When I stopped using it, the bike had developed an electrical problem and lost spark. The problem could've been CDI, Coil, wiring, or the lighting coil that is included with the engine, I never got around to diagnosing the problem, as, due to my injury, I wasn't really motivated. Thus, the lighting coil is not guaranteed to be good.

    The kicker shaft and right side case cover are both new. The kicker was skipping, and the cover was cracked. This can happy with these engines if it kicks back.

    The engine likely only has a few hundred miles on it. When I had it apart to replace the kicker shaft, everything looks great, the cylinder doesn't show any where, all cross-hatching is still visible.

    This engine cost around $1,500 to build. I'm only asking $750, OBO + actual shipping charges.

    This is my old bike!!! I had Terry build it for.me. Wow small world. Put into a 1977 ct70. Very fast and fun bike. I even changed sprockets b/c the first set was way to low. Great power and very fast. Im from Ohio and sold it on eBay just b/c I didn't ride it much but sure was an attention getter.

    LOL! I'm selling it for pretty much the same reason, I didn't ride it much.
    Then, it lost spark. I never got around to diagnosing the problem. A friend wanted a titled CT70, but, not the wild motor, so, I sold it to him w/o the motor.

    It was a fun little beast, but, I messed up my back (not riding), and starting it was getting a little tricky for me.

    I know this engine is pretty reliable. As for the kickback, oh yea I been there a few times. This bike was set up nicely too. I enjoyed the little Pirelli's, made the ride smooth. It was actually surprisingly stable and smooth for doing over 70 mph, well according to the trail vapor speedo. Where you located? I just remember the guy picking it up from me with a trailer with like 3 other bikes. Whoever gets this engine will NOT be disappointed.

    I must tell you I'm intrigued by this engine, but........
    Spencer, when did you have it built? from the post it looks like 2010?
    JAS, where are you located if someone wanted to save on shipping and pick it up?

    It was indeed fall of 2010. If I was to guess, I only put maybe 100 miles on the bike with this particular engine.

    How much horsepower does this engine produce?

    I don't know the answer, but I'm thinkin...ALOT.
    A lot of horsepower as far as CT70 engines go. Not for the faint of heart :--)

    That's awesome. I want one. I have an 88cc with race head its pretty cool. I couldn't imagine 195cc's.

    Horsepower potential is determined by the head. Airflow = horsepower. Rough guesstimate, that head will efficiently support 15-18hp. S15 is a pretty mild bumpstick, especially with 12:1 CR and a 66mm bore. I'd expect this tune to run out of breath at relatively modest rpm, i.e. make its power down low. I doubt that it can quite make 20hp. That said, it's torque that moves the needle on the seat-of-the-pants dyno and the torque curve ought be be wide. It should deliver impressive acceleration, from off-idle through redline. If it'll "only" deliver 75mph would that really matter? It'd get there quick and probably pull 65+ on a 10% grade...imho, bulletproof power. My concerns with this motor: octane requirement and longevity.

    The overarching concern with a bike capable of 60mph+ is the rolling chassis...brakes & suspension to match. An otherwise stock bike, taken to high freeway speed, would be a death trap. With this kind of displacement, it's possible to top 85mph and that'd be the easiest/cheapest element in the equation. The cost of each successive mph increases dramatically over the last one. Restraint is the only low-cost alternative...the toughest to exercise, as well. :whistle:

    My guess is 16 hsp. A Daytona Anima 190cc is around 19 hsp with a 4 valve head.

    I agree with racerx as far as where the power was at. It was all lower end power. Very easy to loop the bike if not careful. With the short wheelbase of a ct70, you didn’t have much time to react if you goosed it too much. Mid range power was decent while upper range kinda fell off. I would certainly like to own another one but not sure if the reliability is worth the risk of blowing up a $1,000 motor. It’s not a Honda...

    Anyway here is a video of it before I sold it.

    Peak hp would be limited by the head; with this displacement, I'd expect it to peak at a relatively low rpm. That said, it should make enough for 75mph+...and...the torque curve should be "fat & flat". IOW, power everywhere in the revband and enough torque to pull itself along with effortless ease at any speed one would (sanely) care to ride. Displacement = torque. What I gather from the running description makes me think that the gearing (sprocket combo) was too short; correcting that would make low-speed takeoff more civilized.

    Of course the laws of physics are what they are. Translation: big power increases need big chassis improvements to have balance. Most owners would experience dizziness, chest pains & shortness of breath, upon learning what suspension, braking and chassis upgrades involve. That said, a well-balanced bike, capable of 60mph+ cruising and with enough braking power to yank bike & rider to a stop from high speeds, drama-free, is possible...if one is sufficiently motivated...
