what all hop-ups can u put on a 200x???

[caleb200x]

i own a 83' 200x and i was wondering what all can i do to it to make it keep up with bigger bikes(like z-400's and yz 125's)

put in a cr125 motor is your best bet. you can not mod a 200x motor to keep up with a z400

My 200x has some mods and is not really that much faster, but it did make a difference. I have a 12:1 piston, K&N air filter, supertrapp head and tail pipe and I run octane in the fuel. The trike has more rev than a stock one, but not sure really how much faster it is. You can also do a cam but I hear that is hard on the crank. You can also do a performance carb but messing with a carb on a 200x is asking for flooding issues and hard starts. I got a stock carb with a 113 main jet and it starts super easy and doesn't flood. I think on the 200x it helps allot to run a smaller tire like an 18" to 20" and not the big ballon 22's. Smaller tires will gove more low end.

would a cr250 motor fit in a 200x chassis or would it??? also i would like to know if a cr125 motor would have to have fabrication to make it fit to?

[vartiak15]

yes and yes the cr250 would need a lot of fabing but the cr 125 all you need to do is fab some motor mounts and get custom exhaust!

what do u think a cr125 motor would cost and what year do u think i should get?

[vartiak15]

any year the newer the beter, but you would have to put some radiators on your bike some where. look on ebay i bet you could get an 85-90 cr125 bike for about 1000-1500. if you do this i would get the whole bike so then you have the carb, electroonics, and radiators.
