196cm3 roketa engine finish

[puncho5]

Hello Everyone im new here just thought i bring some of my work here to let you guys see the events me and my friends are doing and done we have been and the pocketbike game now for about three years from the 49cc 110cc 125cc to the 196cm3 me and my friend race the bikes a quarter mile the bikes are running to fast it un f wording believeable only problem is my friend has the 15/22 and i have the 15/28 sprockets he leaves me 2 1/2 bikes ahead also theres a weight ratio vs hp in thier to, my other friend had pbu to do his 143cc inner rotor and inferno ing oil cooler 17/28 gear thats coming this week he has to breakend first but the video is coming i will upload as soon as it done so you guys can judge yourself thers was only little moding needed to be done the engine should have came on this bike this is the only bike that will hold the 200cc without fab work only thing need to be done is grind down the top mountin bracket because it hits the engine case i just put the top mounting bracket for reinforcement but overall this bike only bike has major engine diplacement upgrades.

Hoooly crap man...thats awsome! Can you mount a street exhaust pipe on there?good job though man!!rock2bows_smiliethumbsup2

[Midbike Racer]

WOW! Very impressive. rock2

[schofell84]

whoa.dude.punctuation.helps.

im pretty sure the marking 193cm3 doesnt mean thats its displacement. still a cool engine though.

Schofell what size do you think it is? I saw the reinforcement...but didn't Yamaha have to out bracing under the engine on the FZR600 because it would twist the frame in knots? Punch have you cranked her down a strip yet? I think she would be a handful to ride on a road course. But I'd sure give it a hell of a try.

[X7rocks]

vary nice work done
but this motors output isnt that great my stock 124GPX beat these motors
but still a nice job atleast you have a 5 speed nowthumbsup2
oh and the color combination is really cool

[swheels]

thumbsup2Yeah you did a great job.!thumbsup2


Hey x7 you gotta remember that the bikes that motor normally came in is almost 3x heavier (mabey more)than the x18's.So now that motor is basically just pullin the rider.The rest of the bike is just there for the ride.

Now it looks more closer to scale all motor.The motor has got to have some weight to it though.thinking_smilie

Lookin at one pic.I see what could be a potential problem.Looking at the front drive sprocket in relation to the angle of the rear drive sprocket.Theres a chance that if you run over a good bump when the suspension compress it will tighten up on the chain.Possibly even pull the motor out of alignment,tweak the rear swinger or pop the chain.Becareful.

OOOOOHHHHHHH DOOOO I LIKEEEEY
cant find the drooling emoticon

That's nice!!!

[X7rocks]

swheels you do put a vary valid point
since it was a large scale dirtbike that it went in now its in a 18 it should be a rocket
i would like to see how it sounds with that exhuast though

i would like to see how it sounds with that exhuast thoughI would love to put one in the other bike since it doesn't look like i'm getting the watercooled 250cc motor.But i think that motor has got some serious weight to it.For drag bike i think it would be great.It haulmoon1

[schofell84]

it looks like a 200 but anyways you know the 124cm3 deal with 117's. id love to get one of those 5 speeds in a smaller engine case ... hrmmm.

the xr200 engines (which that one is based off) have the same case bolts that mount to the frame as our engines. the vertical engine can be swung horizontally by boring the cases. i believe the new xr200's are dohc also?

Dude you were a troublemaker in highschool I'll bet bluelaugh hanging that out there and scootin. Boy I love a challenge cowboy

[schofell84]

ha yeah, someone builds em and puts em on ebay for pretty cheap. they were big with honda atc dune racers.

[stuntnx7]

ive got a 250cc 2 stroker quadracer engine i was thinking of doing this with...would be quick too...hmmm...idk i might just sell my fresh 250cc engine and get something else

[puncho5]

Thx for all the replys guys x7 i remember a year or so ago we use to pm each other on pbp when you had the blue x7 and you said you make sprokets and you were getting some 52.4 hi comp piston for the 110or 125cc with 13mm wrist pins, but anyway thats another story anyways guys this bike and my freind x8 strecth is very very fast it will shock you people,we have took kids bikes and made them monster, i have the rocketa and my buddy has the zonshen 196 china stamp this bike is nothing but motor it comes up on a wheelie while rollin in 3rd gear,i have a beef up 125ccin the garage that i dont use anymore since i found real speed.

[X7rocks]

id like the inner rotor kit :D

[swheels]

Do you guys just drag race? any road course racing?

[puncho5]

i would like to see how it sounds with that exhuast though It sounds like a drag engine you can hear the stock cams roaring while ilding you can feel it while standing next to it when twisting the throttle me and my buddy gave some x12-x15 110cc 80yards+ sunday while racing the quarter mile we caught them before they shifted to 4th gear, the gear ratio with the sprockets are long.

[puncho5]

no course racing only drag not that i dont like it we just never tried it we just like to see who can get from start to finish the fastest off the line feathering the clutch popiin wheelies and running we have brought so many hop ups its crazy i have so many parts for different motors we could open are own store we have spent major $$$$ with pbu, honda, cyclegear, classichonda,if anyone really want to go fast the cheap way, do this you will come out cheaper than heads ,boring,porting and polish.we brought all those hop ups and could not get the speed im geting now.

Nice work, puncho. What times are you getting over the 1/4 mile?

Swheels, the problem lies with the centerline of the front sprocket and the pivot point of the swingarm, those have to be on the same centerline so the chain won't tighten or loosen up.....The way he has the bike set up with the engine sprocket higher than the pivot point of the swingarm the chain will loosen dramatically, if it was vice versa the chain would tighten.....I had this problem on my son's cateye with the 125 so I ended up putting a strut on the rear and removed the shock altogether, the only way to get the two on the same level would have been to cut the entire bottom half off the frame and drop it about 2inches, since the bike is not raced the strut was the easiest solution...,,,,,With these guys bikes I would lower the engine, make longer top mounts and lower the back mount or make a stretched swingarm and raise the pivot point, only problem with that is the bike will take on the look of a dirtbike unless they relocate the shock mount to keep the swingarm more level and not raked so much...

That explanation is exactly why we can't let you leave the game Randy bows_smilie LOLOLOL No fading into the sunset if we can help it thumbsup2

[redryderaus]

Agreed, Nutty. Your knowledge and experience is too valuble to lose, 125ccCrazy. Welcome to the home of Midbikes thumbsup2

Ideally the sprocket would be on the same axis as the swingarm pivot thus giving no change in chain tension regardless of swingarm movement. Unfortunately this is impossible to achieve with the common designs used.

yea funny neither bike had a chain on

[puncho5]

yeah my chain loosen a little bit because of my weight but its not a problem i have rode over bumps and everything now when my son gets on it stays the same i have took links out of chain and push the wheel all the way to front of swingarm because theres so much torque snatching the tension screws strip, so theres not much play, as long as the chain lines up, and the chain/wheel spends freely without rubbing anything theres not a problem,i see here theres a lot of guys here who know there S**t i like forums like this,iam always open source for advice me and my profess fab guy look at all this but i got it to work with no problems now my buddy ran into this problem with his strecth bike he had to fab 2 steel pipes like the spring sets to keep the swing arm stable to keep the chain from rubbin in comin off because the 22 is so small.

[puncho5]

yea funny neither bike had a chain onSo blits you still think my bike is photoshop huh, i love that little pm you sent me on pbp i still laugh to it.hangloose

[Blitz$M.Inc.$]

uh you must have me confused, i never sent you a pm
never said anything about photoshop either
i just said there is no chain on the bikes

Thanks H and Red, just throwing my 2 cents out as usual LOL.....don't know it all (yet) LOL, just speaking from personal experience with live and learn situations I guess.....
I'll hang around from time to time but I am getting out of the bikes..kinda boring riding by myself....my kids don't sem to care about them any longer so time to get rid of them and make more room in my garage for my hot rod....

[chwiej]

[chwiej]

Wonder if we could put these 2 strokes in midbikes?These scooters are crazy fast!

you can set your bike up with one of those scooter motors.But do you know how much it will cost you to get yours to run like that?$$$$$$$$$LOL

[125ccCrazy]

Now that makes me want to talk my buddy out of his 125cc 2 smoke dirt bike and put the eng on my x12...... That would be pretty crazyrock2

[s0utherncalinate]

DAMN!! he smoked the R6!

WANNA sell that 125cc?

[stuntnx7]

DAMN!! he smoked the R6!




he got tree'd bad.....and he cant ride...no way a scooter anything would keep up with a real bike

[Blitz$M.Inc.$]

well its 2 stroke vs 4T
