    hi i just bought a 48cc skyhawk engine off of ebay for $100 shipped. are these engines better than most of the other names? and what is the top speed on these engines? any info would be great.

    Thanks Erik

    I believe that the 48's will get same speed, but have less 'pull' (torque)
    we have a 48 and a 70 on schwinn choppers and the 70 pulls a lot harder

    That's a great price. Is this a new, in the box, kit?
    Skyhawk & Starfire are Grubee brand names. I have several of these 48 & 55 cc engines. I wouldn't say they are any better than other brands, but will say they are as good as any out there.
    You can expect to run 26 to 32 mph top end. (depends on rear sprocket size)

    yes it was a new engine not the full kit just an engine i still think thats a fair price since most places want about 150 for a replacement engine.

    yes, $100 for a new engine is very fair...good for you, does the seller have more? care to share the link?

    was this from revolution cycles, aka motorizedbicycles.net, aka brian semones ?
    I have seen him selling just 48's on e-bay
    if so, he is a low life,
    be carefull

    I don't know what interchanges with what (internally) on these "Happy Time" china engines.....But, Dennis Foster is still Don Grubee's "go to" guy for parts.

    Are you building another bike or replacing one of your current engines?

    I am replacing the engine on one of my bikes i had 2 80cc bikes but i had a piston shatter in one of my engines so i took parts from the other to fix the broken engine and now the piston is poping up above the head i think because i have a piston from another engine it think its a spitfire engine piston and the engine jug and lower half i have it on is a daxs so i have to try buying a piston from thatsdax.com and see if that fixes that engine. I figured so that i have a bike for the summer i mine as well pick up that engine until i either fix my 80cc or buy the 4 stroke kit that i want to get, just cant afford rite now. I loved my 80cc bikes i wish they were still working hopefully i can fix the one i have with just a new piston. kings motored bikes said he would sell me a replacement 80cc engine for 145 shipped so i may just end up buying another 80cc making that the 4th 80cc engine i bought lol

    that's ok, thanks anyway...if i knew who it was i woulda never asked for the link, he's NOT welcome here.

    the sticky is gone because he went crying to don grube about us costing him his reputation (like we could make it any worse) and business, tom felt sorry for the guy...i don't. if he ever comes around again, i'll gladly show him just how far i can reach if i have to.
