    I'm wondering if it's possible to remove the 35cc Robin-Subaru and replace it with a 25cc Robin-Subaru on a GEBE setup? I keep hearing nothing but good things about the smaller (and quieter) motor.

    Actually my EHO 35 is quieter than my EHO 25.

    I don't believe so. The 35 uses a 76mm clutch and the 25 uses a 52mm clutch. So the clutch housing will not match up.

    Wow, you have both, Torques? Lucky guy :) Thanks for the info.

    Zev0, thank you sir, for the information...I'm glad I asked :)

    Have a nice peaceful Sunday, all!

    Well, Zev0 and Torques, it's official! I'm now a 25cc Robin-Subaru rider :) The clutch came with it, and it's mounted on the GEBE frame no problem.

    astring, as far as noise difference, there's not much difference. It's just a tad less from the 35cc. probably because i'm a little deaf :) As far as power, it's 24 mph top end, and it's a used one, so who knows how many miles of abuse it's taken. From an assisted start, I can barely tell it's a smaller engine. I'm 160 lbs, so it won't make a big difference. I like the smaller 25cc for farting around the neighborhood. I'm building a GEBE bike for a friend in a coupla weeks, and we both can't wait :)
