Default Re: interesting experiance, trying to blow up a china girl !!

ok back from a ride ....

i have no proof of speed although i realy did try !!! i taped a gps to the bars and tryed to video it with my phone but its too dark and the screen just looks like its all blury and u can not make out the numbers .

so here are the stats any way if you wana take my word for it ...

i got her up to 36.7 mph top speed i saw on the gps so far tonight and most riding was on lvl ground. so engine gear ratio is 4.1:1 and with a 44t drive ratio is 4.4 to 1 and 26 in tires at 36 mph is 8,556 rpm ... not bad

i was riding along and all of a sudden i lost power big time !!!!! i was going 32 or 33 and all of a sudden BBBWWWWWAAAAAA.... its like its not getting enough gass and dropping in power rappidly !! ohh yeh i thought here comes the bang so i brace myself and nothing happens.... i just slow my ars down to a put put and shut it off. i give the motor a look over and low and behold the air filter broke off the carb !!!! lol the rubber piece that joins the filter part to the ruber carb conector seperated from the vibraton ! i guess it wont run correctly without the air filter ! for the life of me i coul d not find it so i putted home lol

time to order a nerw CNS ccarb air filter

any one know where to get one ?

sick bike parts has a 90 deg one that looks nice but will it fit the CNS v3 ?


ohhh and i promise a video when its light out lol i hope i can rig up a makeshift air filter untill then

Default Re: interesting experiance, trying to blow up a china girl !!

just checked my bike over and damn it .!!! my rear hub is worn bad !!! lol its catching in a spot and gripping the tire so it wont spin freely and there is drag on it all the time , but not enough to make it so i cant pedal it it just makes it hard to pedal and is prob limiting my speed .

i may get a new air filter and swap my rear tire out to a free wheel or just swap the motor on to my diamond back mt bike until i get a new hub

i guess a cheap wal mart 100$ beach cruiser hub cant stand up to 30 - 40 mph speeds for weeks strait ! ROFLAO !!!!

i think the break syst inside is compleatly worn to sht and gripping the hub

man she sounded like she was crying lol

well i am going to ride it no air filter and worn hub and all until it blows lol !!!


had it up to 36 mph and 8,556 rpms with no filter and a hub thats locking up !!!!

man she sounded like she was crying lol

alright guys i pulled the chain off to see if it was just the motor catching via unadjusted clutch.....

nope lol the hub is DESTROYED !!!!

i cant even spin it by hand in some spots ! it will spin by hand hard in some spots then catch and i need a mule to free it !!! i cant believe i got the bike up to 36 mph with that mutch friction holding it back !!!!! i took a video of me spinning the hub and i am up loading it now also i am taking pics of the new bike its going on.

video of the damage to my rear hub, the motor chain is disconected

lol the bike is blowing up before the china girl !

ok i am srsly starting to doubt most peoples speed claims here on the forum, lol it seems like a lot of people claim 40 mile an hour out the box with a stock motor or even that there x,y,z brand engine does 9,000 rpms stock lol well i srsly doubt that because in order for a stock motor and sprocket to reach 40 mile an hour on a 26 in bike it would have tobe powerfull enough to turn at 9,000 pluss rpms !!! i highly doubt that any stock motor will send you down the road at 40 mile and hour and 9,000 rpms on a 44t rear !!!

i mean i have MAJOR port work and nearly 13 to 1 comp with a modded piston, a 16mm carb and perfectly port matched intake and exhaust and a custom x chamber and 40 mile an hour is at the verry top of my speed margine here, i call fubar on those claims ! my bike is nearly 3 times more powerfull than it was stock and there is no way those guys would keep up with me on a stock motor !!! NO WAY !!!

i mean i am trying to break this thing by reving it to the max and holding it there and my speed is 36 -42 depending on the weather, heat, and road !

ok here is my piston ... you can see how its running and the port ramps i made, also you can see the skirt cut 1/4 in on the intake. it has been holding up to this abuse quite well i would say .

also the puch head, it has some carbon build up but seems just fine and the plug looks good.

Default Re: interesting experiance, trying to blow up a china girl !!

ok here is my port work and jug

you can see the intake has been ground to a D shape and hogged out as far as i dare

the exhaust is ... well ... just huge lol.

i ground it out to an offset D shape and i can fit my thumb through it !

the cylinder wall is pretty good considering the abuse i have put it through for the last 3 weeks lol some glazing and a lil bit of scoring but still useable

the piston has some blow by where the rings close together and where the exhaust port is but thats to be expected espesialy with sutch a large exhaust port.

its all going back together and on another bike untill i get my trike rear end and new hub
