How do I build a shifting kart using a CR250 Dirt Bike Motor?

We used to build a Go-Kart frame similar to the store bought and make enough room for the Engine to mount behind the Seat. IF, it not have electric start take into consideration room to use the kick starter or mount a Rope Pull maybe using a compression release. Make a rod to run where you want the hand shift and use pedals for Clutch, Brake and Gas. Good Luck, it a fun project and you should be able to use a nice size tire, look for a cost effective Tire set up.

You should shift based on your cadence- your pedalling rpm.\n\nKeep your pedals moving at the same speed, and shift to maintain the pedal speed.\n\nThe larger chainrings (on the crank) give you giant leaps in torque while the cassette (in the rear) fine tunes your efforts.\n\nIt really doesn't matter how you shift the bike, as long as you avoid using the two largest sprockets and two smallest sprockets whenever possible. In fact, I would recommend that you NEVER use the large/large combination, and use the small/small only as a starting point if necessary. \n\nMake sure you are pedalling when you shift, and that you only shift the front or the rear at a time...don't shift front AND rear derailleur at the same time.

Your question is SO unclear.\n\nWhy are you not looking for submarine motor kits? http://www.patronic.com/motors/motors.html\nhttp://www.dogpile.com/info.dogpl/search/web/submarine%252Bmotor%252Bkit/1/-/1/-/-/-/1/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/417/top/-/-/1/0

well there isnt, not stock anyway.but i would say 110cc racing superbike upgraded to max,with mini bike nos kit,new honda 110cc upgrade engine,mesh airfilters,plastic,or carbon fiber replacements,best way to do it = )

hey no worries ! u need not need ne xperience ! go karting consists of ony steering, acceleration n braking ! no gear control !

Get off the computer and get outside and use good old trial and error.  Build a ramp of dirt--it may be easier to make a pile of rocks (or whatever else you have in your area) and cover it with dirt.  Jump your bike off it and then adjust it as needed.  Buy a mountain bike video (The Collective, Kranked series, etc) and check out how they build theirs.  They will be bigger and the lips will be more vertical, but you can scale it down.  Also check out photos on online forums (MTBR, NSMB, ridemonkey, busted spoke, etc).  People post their dirt jumps all the time.\n\nIf you know of any BMX jump tracks, check those out.  But realize that a MTB wheelbase is longer, so the curvature of the ramp/lip needs to be a larger diameter.\n\nIf youre only going for 3' of air, you can probably land flat or build your jump so that you land on a down-sloped transition.  When you progress bigger than that, you will probably build your own transition exactly where you need it, and at the angle you need.\n\nCheck out Bellingham, WAs dirt jump park--my buddy helped develop and build it.

there are 3 ways to do this. \n1) electronic method (digital method). it wont be possible for me to show you the circuit diagram here. however its efficiency is very high!\n2) transformer - you can make a transformer in which the primary coil should be of less number of turns and secondary coil should be bo many times higher in number. i calculated it and it came to the value of 20,000 turns in secondary coil. it wont be possible for you to make such a big transformer?? even if u make one, where will you keep it? and also it consumes a lot of electricity to give a low out put. that means that its efficiency is low.\n3) motorized convertor - you need two motors. one that runs on 12V dc and the other that runs on 220Vac. dc motor should be powerful enough to rotate the ac motor. so, you can use the motor of the car ventilation system. its very-very powerful!!! it seems that you are from india. so, you can go for the motor of maruti car. now all you need to do is to connect the shaft of both motors and run dc motor. along with it, ac motor will also rotate and it will act as a dynamo and produce current. though the current produced will not be sufficient to run any heavy electrical appliance. however you can surely light a bulb.\nhope that i have answered your question. for further enquiry you can mail me at\nmangeshome1982@yahoo.co.in\n\nall the best!!

35-150 psi.  Start with 40psi and tune from there.\n\nCheck this pdf out:\n\nhttp://www.kleinbikes.com/assets/asset_upload_file610_1187.pdf\n\nTable 7 at the bottom.

To start off, install a K&N air filter,or something of the same type. Next, put in a real good set of plugs{spark}like split fire,LGSpremium,Bosch.... Then ask around at the local parts place and see if they make a better chip for the Cav. I'm into V-Dubs so I don't know for sure if they do.Next make the exhaust as free flowing as you can and still be legal.  More air in, better burn, more air out makes any motor better.Most of this can be done fairly cheap too.  Have fun.

Take the top motor cover off. There should be screws/bolts securing the bottom half of the motor. Take the screws/bolts out and you should be able to slide the bottom half down and off. Your best bet is to look up the schematics for your specific motor. Most of your motor manufacturers have a link for parts and service with schematics for your motor. Good Luck!!!

Too many moving parts and I can never seem to find the owner's manual that comes with them

Try Global Spec. It's free and allows you to put in your desired torque and rpm, then shows you matching products. Keep in mind they will spam the email account you register with mercilessly.

I think you need to ask a more complete question pertaining to what you want to do.  Once you've formulated that question, try very hard to input the letters of each word correctly so that old f__ts like me will know what you mean and respect you enough to give you a real answer.  \n\nSorry, your question was not misspelled (except for "quading" whatever that is).  I apologize, it was another question I read recently that was so bad, I couldn't make out what language the person was trying to use.\n\nIs your project about installing four-barrel carburetors on an engine?

it is under Dodge tool. Or you can use Shift+O to cycle through Dodge, Burn and Sponge tools.

Hi. Not to discourage you but the shape and sealing of a Wankel rotary engine are a bear! Good idea though. Power to weight is good and an R/C does not have to meet emissions. It is possible : http://www.berkeley.edu/news/berkeleyan/2001/04/10_cmbus.html
