my poor old 200x

[probed_out]

hello everone im new to the forums and i love three wheeler i always have my first taste of three whellers was an old atc 70 that my uncle gave me then i trded it for atc 110 that didnt run and i gave up on it and sold it latter my dad gave me his 85 200x and i wrecked it few times and beat the poor thing half to death

anyway it started burning oil really bad so i deiced its time for a rebuild and i want more performance out of it so i will up the commpresion with a wiesco piston

and im pretty much stumped on what eles i can do to it mayba polish and port the head? is there a such thing as bigger valves for these things? can i cam it? etc

you guys can feel free to add anything to my short list

thanks in advance

Doesn't look that bad, seen way worse.

There's a manual for that.

yeah it needs rear fenders really bad and a rebuild that engine smokes so bad its not even funny

[oscarmayer]

there's a tone you can do to that motor. how much are you willing to spend is what determins how fast it goes. $400(parts only) gets you a swiesco and a basic rebuild and maybe with a good deal new clutches. $1k(parts only) gets you a full rebuild with CNC valve machining, web cam, web hardened rockers, performance springs and titanium retainers, 12:1 weisco piston ported head, new performance clutch setup.
so it's a matter of how much you wanna spend is the truth.

megacycle cam and rockers 300, gasket kit, 40 bucks, oem clutch 100+ 12 bucks for barnett springs, piston 120 (includes bore), new springs and keepers 100

there ya go

you can also rebuild just the top provided the rockers and cam aren't messed up for about 160 bucks. just a piston and gasket kit...which will include new valve seals.

okay thanks ill give top end a build with wiesco

my clutch and springs are only 1 year old and probally only have 50 miles on them so i wont touch em

it might only need valve seals but i might as well do it right the first time

thanks everyone

do her up right,thats a nice machine when done right.do your top end rebuild and check everything carefully.sprockets and chain,brakes,cables,then do your cosmetics.she is a keeper.

[probed_out]

i put on new sprockets chain and a clutch cable and handel i need new brakes though theys gettin thin and the front rotor was very bent so i took it off so i need one of those

thanks for the heads up

a quik question this thing has always fouled spark plugs like crazy im gueesing its was running rich could it be the needle and seat?

[oscarmayer]

yea i would def do a carb rebuild, especialyl if your doing a top end. that way you know everything is new and right. make sure you use the 110 jet in the kit if your going with a weisco piston.

if your interested in cnc valving or poritng contact www.theoldone.com (endyn) tell them mike sent ya.
