k lets go over this again cuz i've got a new goal! im no longer looking to make the worlds highest hp horizontal motor yet i still want mad power and most important gas mileage! the gpx 160cc stock with a ct70 tank which swanni said holds just a little under 2 gallons only gets 42miles per tank going by Dan lorenzes gpx 160cc specs. which sucks! i thought these get like 140mpg? anyway doing a 178cc s cut kit is not the answer to gas mileage! but i was thinking! the lifan 150cc has a small tiny bore of 56.4mm vs the yx 60mm+ pistons yet it has the longer stroke which means with the smaller bore gets better gas mileage? since theres less room in the combustion chamber for air/fuel. so someones selling a 57mm bb piston for the lifan 150cc which the lifan is really only 147cc's and this 57mm piston sets it to 150.1cc's. well what if i bought the lifan 150cc engine then sent my cylinder out to this guy to get bored for the new 57mm piston and ready for the question? bolted on a takegawa +r head?! will this +r head fit the lifan 150cc? or is it for the gpx/klx motors only? and then theres the v2 head which from what i read is not as good as the +r head. im thinking a combo of a nice head with a long stroke and smaller bore will get good gas mileage, be reliable, and fast! what do you think? or whats this star motor you're wanting to build?

i wonder if anyones even considered putting a 200cc vertical into a ct70 now that would be some shit! but i wonder if it would fit? i definitly know there would need to be another or bigger gas tank to go for a good ride cuz the gpx 160cc stock gets 42 mpg on the ct70 and thats not much my civic gets better gas mileage and its a car with 4 cylinders and a way bigger engine! somethings not right. its that Dan Lorenze guy that i got those gas mileage figures from his thread at planetminis.

finaly found you
how you doing
see you later x7rocks

so the lifan 150's are better then the yx150's after all! i've seen all these horror stories on planetminis about all these 150 yx motors having problems like one guy broke the engine trying to kick start it! and i seen others. so far theres a few that are having problems with the lifan 150cc popping out of second gear at high rpm! which cant a kitaco or takegawa parts fix this stuff? like putting real polini parts on a rep for example? but you know these guys are driving the hell out of those pitbikes! im just gonna be cruisin trying not to scratch my bike lol my engine will be more for cruising and highway mileage not wot track riding with stopping and going dropping the clutch every time.

how fast do these 150-160 motors go anyways? can they cruise steadily at 75mph for hours?

lifan 150cc with 59mm high compression akunar piston and race cam for bvh ported with a 30mm mikuni and big bore pipe is that any good? or how much can you bore the lifan 150cc to? its got a 56.4mm bore stock with a 15mm pin. but the stroke is 59mm!!!!! thats more then the 160cc gpx! can a scut kit fit the lifan 150cc? and whats with this v2 head? i read something about bigger fully stainless valves?

now that i think about more it might be better to just buy an x18 and sell both x7's and part out the x18 only keeping the things i'll need.

well i was gonna get that pbu extended swingarm cuz they make one for the x18 and x7 and they both look 100% identical. and yah i'll prolly order an x18 front end and title from Jay its all i'll need! unless the 200cc wont fit the x7 but i thought the x18 and x7 have the exact same frame?

but i dont have one and i have 2 x7's and the x18 wheels all i need is a title and extended swingarm with a 200cc vertical and my ass would be set!

do i have to buy an x18 or can i just put a vertical 200cc into one of my x7's?

cuz i already got a set of x18 wheels brand new never used!
