200x twin need help

[Xfactor]

New to this site thought id share with you and get your opinion on my new project. its an 85' 200X with an engine off an 79' Yamaha RD200.Its a twin cylinder 2 stroke engine i have it almost complete it runs just have to finish the exhaust and air cleaner etc..Let me know what you think:D

[Vealmonkey]

You need to post some pictures to get a better idea of what people think. It sounds interesting though. I hope you built this trike safely. Welcome to the boards.

[Daddio]

We need pics of this. Oh, :welcome: aboard.

[Xfactor]

here's a pic tell me what you think

[Xfactor]

here's another pic

Looks like your on the right track. How do you plan to run the exhaust?

[Bigbore]

Looks nice. :beer


Mini Banshee power :lol: It does look like the front of the engine needs to come down a little.

[Xfactor]

I'm working on the exhaust now i don't have the pipes off the motorcycle so ill have to fabricate some,but it will have dual pipes cant waist that opportunity :D also thought the tac was cool

[factoryX]

ok this is sick, you have room to make the pipes go back up in the frame , also what you could do is turn it into a 2 into one pipe take, and simply find a 200cc 2 stroke pipe from a dirt bike and take the the pipe mounts and weld them to the dirt bike pipe. How did you mount this?




Banshee 2 in 1 pipe, and the other is a kdx pipe.

WoW that is verry cool i was thinking about something similar the other day......

[Xfactor]

i ordered the air cleaners the other day there isn't enough room for the stock air cleaner being there's two carburetors so i ordered these they clamp right on the carb's i think they should work pretty good

[factoryX]

This bike should be freaking awesome, the motor stock has 22-24hp. and should wiegh less than the 200x motor.

[Xfactor]

The air filters are here but look what is on the box

[MTS]

nifty project, cool thing about them old RD motors is there is quite a few ponies to be made over stock with revised porting and correctly made pipes

[85BigRED250]

haha awesome!!!what kinda filters are those?

[Xfactor]

the filters are Standard power filters got em on ebay

[Xfactor]

So there wasnt enough room to mount the filters on the carbs so I bought hoses to extend them out this is what this looks like

[MTS]

might wana re-rout thos's there gona get a trailprotrailprotrailprotrailpro ton of dirt in them like that,

[factoryX]

just screen them then...

[sandpuppi101]

I use similar air filter's to what you have there,those must be oldschool with the trike on the box-anyway's I use them on my MDR 600X,and when they get dirty I clean them 1 time and just pitch them after that,there not a k&n but they work good.

[Xfactor]

So i found an 86 200x that needs a new top end but its in better shape then mine and the only want $100:D so should I fix that one and use mine for parts and put my twin cylinder on my brothers yamaha blaster which I think would fit better anyway or just forge ahead

[userj8670]

Hey man nice build. :TrikesOwn :w00t: Where in western new york are ya? Just my two cents worth but them plastic hoses to extend the air filters might collapse over time due to the vacuum.

[Xfactor]

im in the Olean area which is 50 miles south of Buffalo the air hoses are thick industrial but thanks for the tip

[Tecate250]

Man I think this bike would be a good example of a bike that could have been. Do not throw it away on a blaster. Retro engine in a retro frame.
Goda love that

[ironchop]

believe it or not...JC Whitney had Yoshimura silencers for Rd`s for a good price...bolt-on performance

my RD cafe racing builder friend uses the old Roost Boost bottle on his RDs and claims mega-improvements

those RDs were high-winding bad mofos

[Xfactor]

thanks for the tip ironchop I ordered some and there on the way:D

[outtaline]

:beer Dude that thing is fn cool I'm puttin parts together for something right now 200x cr125

[300rman]

take your time on the pipe. you dont want the stocker anyways, go with a newer KDX200 or similar pipe, it will really wake that motor up.

[Xfactor]

just an idea but i think banshee exhaust would be the next best thing being the rd200 is just a smaller version of the rd350 which went on the banshee let me know

[factoryX]

I don't, pipes will be to big... you would need like 2 kx100 pipes..

[Xfactor]

hey sorry haven't posted in while been busy. Got tired of seeing it and not being able to ride it so i stuck some flex pipe i had siting around on.put the silencers i got from JC Whitney in it. presto gave it great back pressure about same as stock and amazing power gave me a great pattern for the permanent exhaust ill post pics later

[factoryX]

......pics..........

[SYKO]

flex pipe? oh man..... I think this build should have some money spent on custom pipes made your in NY hit up dynoport!

[factoryX]

I still think a 2 to 1 pipe is better than thi set up or even 2 kx 100 pipes...
