    It looks like it will work fine. The only issue you will have is the front mount. Those oversized tubes can be a pain.

    I'm having some troule with gasbike. They got my $$, but havn't sent order. No e mail response. Might be better to go with one of the sponsers here. Ckeck out vendors section. Good luck. Welcome to the site .

    I emailed them a few times, and have gotten responses immediately. Where is the nest cheapest place then? I am looking to spend about $150 total with shipping. Gasbike can get it to me for $141, they said they would hold one from Cyber Monday at that price for me.
    EDIT:
    So I'm thinking about powerking, then I can get it for about $125 shipped or less and they have good reviews. Also, what do you mean about the front mount? Sorry to be a total noob but if you could explain a little more about what you mean that would be great.

    All I will say is there is a difference in engines and you get what you pay for in quality and customer support, and as far as the 80cc to 49cc the 49's run circles around em.

    So a 49cc is BETTER than an 80cc? Because many seem to order 80s over 49s and 80s cost $15 more or so... I think I'll go with the original bike.

    well I have both a 49 and a PK 80. 80s first off aren't 80s second there built for more torque not speed its not going to be like a 80cc dirt bike pullin wheelies. I think its a common misconception that an 80 is going to be better I say to each there own but like I said I have both, Equally fun personal opinion buy both see what you like, shoot a 32cc tanaka smokes an 80cc!

    Well I am probably going to go at 30mph MAX and not be riding it too far away so idk which one to get but $125 buys an 80cc from powerkingshop which doesn't seem too bad to me.

    Go with your original bike idea & research here how to securely mount the engine.If your not towing anything get the 49cc;bigger isn't always better.

    Which 40cc kit and engine did you say will do circles around the 80's....I just built an 80cc and I have to say its very sluggish and slow from what I expected. I have 3 Goped scooters with a 42 cc engine from Zenoah and those are hitting 35 mpg and acceleration is awesome.

    So, when I saw an 80cc, I thougth wow, I can't wait, but the truth is the motor is slow....so what other motor did you say can do circles around the 80cc?

    What speeds are you getting on your 80cc? I was hoping for 35-40 mph with my bike...

    I have my starfire 49cc and smokes my pk 80 all tho my 80 is nice on hills I can get 30-35 on my 49cc but I run a 48T on her and my pk 80 runs a 44T if you were to run a 44 or a 36 on my 49 it would easily go 40+ but hills wouldn't be much fun not that its a problem but it does bog a bit not to mention I'm a big fella 220+ on an old steel bike :whistling:..But I love and ride daily my stage 2 grubee 4stroke my 2's are just for beer runs or playing don't really ridem much since I got that beast dialed in.But that's a whole other story.

    Looks like the bike would work size wise but I think the only draw back is it looks like a coaster brake.

    So, everyone agrees that coaster brakes are not desired for these kits right? I actually replaced the back rim on a cruiser with a free wheel sprocket and mounted hand brakes instead......so, even if you do get a cruiser, just change out the rear rim and go freewheel.....
     
  20. The 80cc is only 70cc. I am impressed with my Gru Bee. It starts and runs well although the straight-cut reduction gears are noisy. I have greased them and put corrugated cardboard in to deaden the racket but still sounds like ****. My next move is to see if it will hold Hypoid oil and not ruin the clutch. The mounting problem you will face is the half-circles that straddle the frame are intended for 1 to 1.17" frames. I hada a heck of a time fitting mine to a Schwinn cruiser frame. The rear Komet brake was larger than the sprocket hole so I used a 12" metal lathe to enlarge it. In my case, with the curved downtube, I had to mill a 1/2" aluminum block to space the rear clamp. I still ended up with an engine that that sat too low for a regular sprocket and had to go to a small girl's sprocket. This was ok for starting power, but wouldn't want to peddle home. The crank was too narrow so had to fit the crank out of a Huffy Cranbrook to clear the cases. The fuel screen in the tank is too restrictive and if not careful you could fry the engine with a lean wide-open run. It needs an inline filter and the screen removed from the valve. Try to find a decent kill button or toggle. be sure to blip the throttle on coast to oil the piston etc. I intend to have mine cryo treated for longer life. KW
