    centrifigul clutch those engines are like the other honda clones out there, need to make sure shaft rotation is correct.

    You can tell from the pull start the rotation is right but it would be a little awkward to start it on the bike unless the recoil could be clocked up.

    sfeland Is using this on his recumbent

    "I did have to machine a part to be able to fit the variator on the Harbor Freight motor shaft), and the centrifugal clutch with the spring loaded pulley is used on a 150cc scooter. The shaft is a 5/8" shaft so a Comet Torque converter should work. The 1st drive belt I use is for a 250cc scooter. That should help keep the maintenance down a bit! The final drive was a GEBE system but the bike and I am too heavy and the motor is too strong for the lightweight belt as it lasted about 200 - 250 miles even being very careful. The final drive I use now is the Whizzer drive wheel with a machined V-belt pulley on the Jack shaft. Today commuting home from work coming down a slight hill with some help I was able to get the bike to hit 37.2 mph. Cruising speed is 30 - 32 mph. Someone asked what my gear ratios are... They are GOOD! Seriously....... I will check that out when I have a bit more time and let you all know. I do have a GREAT power band for a heavy bike and I am not lacking power at the top end at all. I do live in Chandler and normally have Monday's and Tuesday's off so if someone would like to check the bike out a bit better, just let me know. So far I have about 1400 miles on the bike, about 80 with the new motor and the rest with the good motor I just took off. So far.... knock on wood, I have had absolutely no trouble with the current setup. It is an ideal setup for commuting.... IMO. Best wishes, watch out for the crazies and stay safe on the road!"

    I have looked at this engine, several times, at our local store.

    The configuration is not right for installation in a bike. It could be done...I was looking at it from a kit standpoint which would require too many modifications to be practical.

    Chris Davis is using this motor with an EZmotors automatic clutch. I think this past weekend was the tryout run. Maybe he' let us know how it went.
