has anybody ever heard or have one of these i was looking at mopeds and scooters online at this site http://www.jimmyjammz.com/newsite/scooters.htm and i saw this claim that a 49cc air cooled stock production engine claims to put out 5.2 hp at 7000rpm, i am wondering if its true or possible especially with a compression ratio of under 7:1, i have a kitted a35 powered tomos targa lx that i love but even with all the mods i don't think i'm close to that power in all honesty. I don't know.... tell me what you guys think about this

thanx

the puch magnum x dirtbike, which is essentially a puch moped e50 with a bigger carb and some other tidbits, puts out like maybe 3-4 hp stock, or so says the tech specs

if you look at the polini website, the stats for lots of speed kits shows like 6-7 HP and up,

i am not sure how exactly to figure out the compressiopn ratios, but i think 7:1 is pretty low, i always just go by the guage, and never compute it to the ratio

brett thats funny you mention the puch magnum x cause thats what i learned how to ride motorcycles on that was when i was 8 and now i'm 25 i loved that little sucker even though it was automatic then i jumped up to a kawasaki kdx80 2 stroke bike, until that i didn't think riding could be any more fun. and here i am many years later riding my tomos targa lx, basically my magnum x engine made by tomos and still having just as much fun, some times more fun than when i was a little kid splashing through puddles of mud and hitting little jumps. when i have kids they are getting dirt bikes when their 4 or 5 i love seeing kids riding i wish everyone had that privilege

Don't a lot a lot of those older 50cc motorcycles (MB5, zr50/x1) make 6-10 hp stock?

with that kind of compression and at only 7000 rpms i highly doubt it. two strokes like to rev so that kind of power would probably have to happen much higher. the old 50cc gp bikes redlined at 17500rpm sometimes.

you can get lots of horse from direct injection but already they had a recall on the 2007 beamer matrix scooters so ya the more there is on them the more there is to go wrong

how does the port injection work exactly i'm pretty good with engines and 2 stroke and 4 stroke theory, is it using a fuel injector just misting in the fuel directly before the port? The fuel injection on bikes is new to me because i really don't have any experience with fuel injection other than on cars, i can't afford a two wheel or atv's with that sort of technology.

most new two stroke marine engines are injected,at high and low pressure,basically sprays a mist.

about the magnumx i wouldnt doubt mine has 5hp.stock except a proma chamber.it goes over 40 with me on it and gets there fast,i dont know about compression but id guess it has around 100 and yeah its turning 7500 easy
