    Does anyone have any reviews or opinions on the grube 4 stroke kits?

    Good question.I don't have any reviews but i do have an opinion eventhough i havn't tried one.....it's the best your going to get.
    Combine a Grubee gearbox/clutch frame mount kit with a Honda GXH50(or clone) and u can be satisfied that you've done your best.
    He also does rear mounts but i don't know how good they are...i've never heard any bad reports so they must be ok.
    Personally i would "hang-out" for the new Dax model if your interested in a rear mount......great expectations there.
     
  3. I've built two. It is a good product. It takes a little time to break them in . Make sure you add 90w (gear oil) to the transmission.

    My opinion? The basics are right- the mounting plate, gearbox, etc., but you should replace all the nuts and bolts you can with quality stuff from your local hardware store.

    I have the Honda engine and there is the potential for good speed.

    I have one.. and..

    I have one. The engine is great !! The Gear box is poor. Very noisy, tried adding GO 90 and it made it worse. The oil made it only slightly quieter, but then the clutch slipped with oil. so.. I drained the oil, the clutch quit slipping, but it is back to being super loud !!! I can not hear the engine the Gear box is so loud !! It is embarrassingly loud. I quit riding it with only 90 miles on it. I have heard some say the gear box gets a little quieter after a few hundred miles. I am not sure of this since I quit riding mine. I am not sure if it gets quieter for those folks or if they are going deaf from the loud gearbox. It was then I then decided to pursue other avenues using 4 stroke engines. Thanks.. Enjoy the ride...

    I saw somewhere that the gearbox was filled with transmission fluid but can't remember where I saw it or just how long ago. The gearbox case was actually drilled and tapped, top and bottom and plugs installed. I'll look around again to see if I can find it.

    I think that I have read about someone trying every type of fluid combination there is. My gearbox is working with bearing grease only and is not at all loud. I got my gearbox late last summer. I read that the gearboxes shipped from late '06 to early '07 were noisier.

    Houghmade, where did you buys yours?
     
  9. If you change the gear oil a couple times & put some mile on her she turn quieter.
    Mine at about 100miles.
    HOUGH is right about the nuts & bolts. I paid $4 bucks to change them

    I don't want to get deep into it, but is the same kit you can get from Bicycle-Engines.com. I am not anxious to send people where I got mine. I got what I paid for and I am happy with the kit, but it took a long time and there have been other issues with my compatriots on this board.

    I paid more, but I replaced everything with stainless...probably not necessary but I became a lawyer so I could afford the little luxuries in life....like stainless nuts and bolts .... ;)

    That's not right...his was a legitimate comment(although provacative) and should not have been quarantined,simply edited.
    Personally don't like the guy but since he is a member here i do believe in his freedom to express his opinions however outlandish.
     
  17. hey let the guy have his say !!!!!!!!

    fetor (and blackmikeybikey)- we have NO problem with disagreement, or different opinions. At all. But, if you can't (or won't) stay civil, then there IS a problem.

    I'm merely asking a question and at NO stage was either myself or blackmikeybikey being a smart-arse,or challenging anyones authority.
    As i said i'm NOT a big fan of RevolutionCycles but i don't want to see his example become the norm rather than the exception.
    MBc prides itself on it's honesty & integrity & these standards are well worth maintaining.......one rule for everyone.
    "NO problem with disagreement,or different opinions".........hmmmm.

    I must side with the moderators on this...Semones doesn't play well with others...why should anyone have to deal again and again with such a contentious personality? Good going mods!
