    I like the Honda 4strokes. Does anyone have experience in what performance differances you would get by going with the bigger engine ?

    I dont have any experience with either. But I understand as performance is concerned, theres not a whole lot of difference. And that GX50 looks big as heII. Id go with a GX35 unless you're morbidly obese, bike up mountains or something.

    I have the gx35 on a staton friction drive, it zips along (no hills no rain in AZ)

    GXH50- 12.1 lbs., 8.9 in x 10.8 in x 13.9 in; 2.1 hp

    GX35- 7.6 lbs., 8.0 in x 9.2 in x 9.4 in; 1.3 hp

    Not much of a difference in physical size, but a pretty substantial weight difference.

    It's 3-1/2 inches taller... which makes it seem much bigger.

    Note that Honda recently 'derated' the HP for the GX25, 35 & 50. (They changed units, from BHP to 'Net HP.') I don't know whether the HP difference is real, or whether there's just a difference in KW between a Brake HP and a Net HP....

    The key difference between the two engines is this: The GX50 has more torque at a lower RPM (GX50:2.2 FtLb@4500, GX35:1.4 FtLb@5500.) Both engines develop maximum HP at 7000 RPM. This means that the GX50 will pull better when the engine slows down - when going up hills, or you're accelerating.

    But, nothing comes for free... 5 more pounds, plus, the engine weight is centered higher on the bike. In addition, while you may be legal in CA, in many states, 48cc's (or more) mean that the bike has to be registered as a motor vehicle.

    how fast does this setup go>? have u had it on any hills yet? thanks.
  8. I recently went from the friction set-up to the staton chain drive over a nuvinci and the difference is exponential!!!

    With the friction i HAD to pedal assist the bike to get about 7 mph uphil. after the addition of the nuvinci i can easily climb most all hills and that same hill i struggled with i now cruise along at 15 mph with no assist.

    top speed between the 2 for me is not different either way. i can just apply the power down low much better with the nuvinci hub and acceleration is much better. top speed averages 30 mph.

    The GX50 if the tank and fly wheel shroud are off it doesnt look very big. At 210 lbs and experience riding with the 50cc I couldnt imagine any thing smaller with less power. The 50cc is the perfect Mab motor IMHO.

    Any problem anticipated with heating with the cooling shroud off?

    Good question, mine are on still but Ive seen alot of guys with the honda/hs in frame who ride with them off. The fins on the fly wheel do help to cool it with the shroud directing the air flow to the block.

    I currently have this engine on my BMP friction drive set up. I also have a Honda GX35. There's not comparison between the 2 engines. The China 2 stroke will out perform the Honda, hands down. A half horse power makes a big difference in these small engines. I'm sure the Honda is a good engine and will probably out last the China engine, which has more power, torque and higher top speed. I know nothing about the Honda 50cc.
