49cc vs 80cc

put it this way i weigh 210 pounds my first kit was a stealth black 80cc slant head wich i was more than pleased with, then after i sold it i decided to try a starfire gen II 48 cc engine wich sounded great bigger ports, better bearings blah blah blah just to realize that i ned the power of the 80cc (66cc) vs the 48cc i mean the engine proved reliable although i didint get a chance to put more than 500km on it before i swaped to another 66cc i bought of bgf and im quite pleased with it
 
well for me its not a fair comparison as i learned all the doos and donts on my stealth such as replace your mounting studs with some higher grade studs i had mine break flush in the engine and the engine being aluminum got damadged wen i tried removing the rest of it so it got so bad i had to cut a square piece out of the engine were the stud was threaded into and i used a new square piece roughly same size as i cut out and just bolted it to the engine ans then covered it with jb weld and it held for as long as i had that bike wich wass like 2000km, and my bfg i tore it completly apart before even starting it and threw in skf bearings and i used "the right stuff " for all the gaskets,changed studs and locktighted everthing so this engine (the bgf) has been really good to me but thats not a surprize
 
I need a chart to follow that last comment! All I have to say as a vendor is I have tried every engine out there , I have to give the hats off to the 49cc, now i mainly deal in 80cc but the 49's are less noise and less vibes.... You do lose power but maybe 5mph.. I like them and are great for cruising..

that and in most states a 49cc doesn't require license/registration/insurance, whereas anything above 50cc generally does, so at least with the 48cc you can swap out the 44 tooth sprocket and drop to say a 36 and still get comparable speed (less pickup though) and still be less one ticket should an officer really want to hassle you..Here in Michigan you need a license even for the 49cc, a 15 buck add on to your car license and a tag on your bike..
 
With my 70cc, I can maintain 18 mph up the steepest hills even though I weigh 200 lbs and am using a 40 tooth sprocket.
 
What A Good 80cc Motor To Get I Mean Witch One Most People Use On There Bikes Somthing That Last A Long Time.
 
ive come to the conclusuion its all hit and miss sometimes you get good motors and sometimes your luck just isint that good i can say im happy with my bgf and ive herd lots of good things about them
 
I'm happy with my Dax so far, although it does make a lot of random noises. As far as I can tell though that is normal and as long as I have power I'm set.
 
o.o

i have a 48cc happy time engine, i can keep up with/ catch up to cars on the local 40kph-limit roads, so realistically they're probably going about 50-60kph, no complaints
 
i concur with the hill climb as well jet80 slant is the same as the bgfslant kit minus the big frt mount and the longer clutch arm. i have a bgf on my personal bike and it really rips and makes no crazy noises and believe it or not barely vibes.. on the other note i bought a gen 2 grubee49cc for way more money than the jet or bgf 80cc slants and its in a box in 10 pieces what a junk
 
i never tried a 49, but i've got a grubee starfire gt4 66cc that i like so much i go in the garage in the middle of the night and make sure it's comfy...
