    HI Gang, what is your favorite "mini 4-stroke" and why? Also what is your favorite 2-stroke mini engine, and again why?

    RS EHO35, so reliable, easy pull start, sounds like a sewing machine at idle, pulls with authority, putt-putt at 20mph all day for next to nothing.
    2-stroke, Tanaka PF-4000, aftermarket mods galore, 50:1 mix means almost smokeless, so reliable, high torque, with silencer not much louder than EHO35 at idle, pulls with EXTRA authority, can putt-putt or go too fast (for a bike) on next to nothing.

    Going by YouTube clips, the RS EH035 engine noise seems at a lower octave & non-piercing. I like it. I went with the Tanaka PF-4000 mainly because it was somewhat cheaper and was recommended by GEBE for higher speed. Plus, I wasn't repulsed by mixing 2-cycle oil to gas. I replaced the stock muffler with a 3rd party Tanaka 40cc muffler silencer kit. It's basically a filled muffler, some 2-ply silicone tubing and a small chrome silencer. At idle it's a soft putt-putt and when running, the noise isn't too bad at all IMHO. Still a long way till break in. For initial use, I bought some pre-mixed 2-cycle fuel. There has been no smoke at all. Taking it slow, but, a few short bursts and I got up to around 29.2mph (GEBE kit). Seems slow, but, maybe it's the break-in factor, or, cause of that muffler silencer kit, but, I'm not overly concerned with getting high speed. I want to try and be discrete out there.

    The EHO35 is a little marvel, you can walk 25 feet away from it and it's hard to tell there is an engine running, there is a noise but it doesn't have an "engine" sound.The Tanaka is just so much more fun, almost no wind or hills can bring you to a crawl as they can with the EHO.

    Interesting! I wonder what the Flywheel and clutch surface look like on the Tanaka? I have not mated a drive up to a 2-stroke, but I am believing we can! The little RS EHO35 is a VERY quiet precision engine, but I am aware that some of the Japanese 2-strokes are very well made.

    Whats next?

    I've had the Honda and Subaru 35's and Tanaka 32, 40, 47 & 47r.
    I prefer the Tanaka 40 most for its power, fuel economy & refinement.
    They just need an aftermarket muffler (stock can is too loud and restrictive).
    They all share the same clutch/PTO mounting dimensions.

    Hi Lowracer, Thanks! that would simplify the mounting brackets tremendously! I wonder of the mounting bolts are same diameter and same spacing? I do not intend to use the small onboard clutch.

    Yeah, all these engines share the same bolt pattern.
    I've swapped engines with no problems just bolt'em up and hope the throttle cable pull is a match.
    If not, I just solder up a new cable.

    Honda 35 is a great motor and is priced right, my problem is having a Honda 50 along with the 35 the 35 will just sit and not get ridden.

    All I have is a new Tanaka PF-4000 GEBE kit and I like it using a lined muffler and chrome silencer combination (connected with silicone tubing). Top speed range so far isn't very impressive- 27 to 29 mph using GPS on mostly flat stretches, but, that could be because of break-in or using the muffler silencer kit. Also, maybe the GEBE mounting needs fine tuning or my mountain bike isn't ideal. Still, it went up a hill at 20mph with ease. That impressed me.

    Hi Westcoaster, sounds like your bike is definitely off to a good start! What hp is that Tanaka? Considering we are only allowed 30 mph on level ground, your bike is currently operating perfectly.

    I have the Tanaka PF-4000 and literature says its 2.2hp. I'm using the GEBE kit and do like it for its simplicity in design and look (at this time, I didn't want something resembling a motorcycle). So far it can easily cruise between 17mph - 22mph. Opening up the throttle and it'll speed up to 25-28mph (not including downhill which does increase overall speed).

    With the GEBE rack mount, I had rotated my Tanaka PF-4000 further away from the seat to make room for a seat pouch (to hold my bike tools, etc). Since I read that the engine will perform better when positioned closer to the seat, I removed the seat pouch and repositioned the front mount bracket to bring the engine closer to the back of the seat. Managed to hit 30.3 mph with the GPS on fairly level ground (not going downhill). Seems to do 20-23mph pretty easy now with only 3/4 throttle. Still, it falls well short of the 38mph I've seen mentioned for this engine. I weigh in around 170lbs, but, throw in the weight of the bike, GEBE wheel , accessories and maybe non-optimal GEBE alignment, and I guess I should be happy to get the speed I get.

    I've got the Honda gx35 & a Tanaka pf4000. both exceptionally
    reliable performance-wise. I think the sooby and the honda are
    pretty evenly matched. I've heard the Honda does better in a
    wet climate, And that's definitely what I've got here in the Pacific
    Northwest. I like the extra power of the Tanaka, but the stock
    can is LOUD & there doesn't seem to be an easy way to tone it down.
    As a result I don't think I've got more than 20 hrs. on it in the
    year I've had it. It's not terrible if I keep it under 6000 rpm,
    but over that I can't really enjoy it the way I'd like to.
    The little Honda's another story, really quiet. I don't really
    care about going much over 17 mph. Putting along at 14/15
    let's me enjoy the countryside. Still the added power of the
    Tanaka is good to have in steep terrain.

    I have a 49cc on a bike rear mount, don't know who makes it. It's China made works fine. Comes from a place called That's Dax, Good people.

    Sounds like a HuaSheng 49cc 4-stroke...basically a Honda clone but with internal clutch.

    I didn't have much luck with one of those, but then I didn't get
    it from Dax. I wish I had. There are half a dozen factories putting
    out the Hua Sheng. I think Dax's arrangement calls for better quality
    control than some of the other dealers. The Hua Sheng is
    actually better adapted for a bike than it's parent Honda GX50,
    though mine, when I could get it to run, was heavy and unwieldy.
    I gotta stick with my little GX35. It's never let me down.

    Hi, I am very careful about what I say because I told the truth in my opinion on another forum and was thrown under the bus. Sometimes the dollar is more powerful than the truth. I just hauled around 120 lbs of food home behind a 66cc Dax motor, on a Schwinn trailer. The girl cashier asked why I had a bicycle helmet. I'm going to take this home on a bicycle. (I left out the motor & trailer part). I have to have some fun.

    It's happened to me on more than one occasion. I hear you.
    Don't let it stop you from telling the truth. Eventually those
    upset will get over it.

    Thanks Brother, The way I see it being 58 years young, been riding since 5 years old, I am here for the enjoyment of the craft. Anyone who says building a Mb is easy is being some less truthful than they need to be. I don't pretend to know everything, no one I know ever has. I Own M&S Motorized bikes. I am retired! No Workie, no mo. I am happy to help others that do not have the knowledge I have over many years of learning. There is no school for this. I did it the hard way, have the scars to prove it. Any advice I give, take it, or throw it away. I am the way it is guy. I have been a member here since 08 I think. I also build custom Choppers, the kind you can ride on the freeway. I'm not special, just have bikes running thru my veins.
