    Advice on tuning after 1/4 turn throttle install

    I installed the rubber caps on the carb but not too much difference at idle (havent ridden yet). I did notice though when tuning the air mixture screw, firstly when its turned all the way in it doesnt change revs it still just sits. Secondly i have my screw out just before 2-2.5 id say.

    Advice on tuning after 1/4 turn throttle install

    Its when I blip the throttle that it happens at idle not riding. I'll stick those vaccume caps on and see what difference it makes before fiddling with the jetting again

    Advice on tuning after 1/4 turn throttle install

    Hey man i just sprayed some degreaser around it and around the exhaust to i dont believe there are any vacume leaks though. I believe the air mixture screw is about 1.5 or so out. What i did observe though was as you snap the throtttle it will build find to half way up then bog until you let it...

    Advice on tuning after 1/4 turn throttle install

    engine is a yx140. should be no exhaust leaks or anything. airfilter is oiled. the throttle seems snappy enough although it isnt dead on. Im thinking it still might be the jetting as i havent completely solved it.

    Advice on tuning after 1/4 turn throttle install

    hi guys, After installing my oko flatslide i bought a 1/4 turn throttle. I fiddled with the air/fuel mixture screw in order to get the bike to rev cleanly as best i could, but is their anything else i need to do in order to get the bike running smoothly? i might go down in main jet to 95 and...

    Running hot after 24mm oko install

    And of course i get that one... haha. Yeah found that when opening the throttle it would rev out then hit a point towards the top where it would sputter a little then continue to try and rev through. so ill go down one from #100 to a #98.

    Running hot after 24mm oko install

    i think ill go up to a 40 pilot and see what happens. If i block the powerjet will i be loosing any performance?

    Running hot after 24mm oko install

    Running hot after 24mm oko install

    Chucked the 38 pilot in it and tightened up the exhaust manifold, also added a 1/4 turn throttle. Noticed the bike idles a little better now but wont start up with the choke on. Is this an issue at all? ill get the bike started and need to throttle a little until it gets warmed up a tad. Whats...

    Running hot after 24mm oko install

    So after a long overdue ride here is the report. With the oko installed i noticed a few different things when riding, firstly when im full throttling in say 3rd i can actually feel and hear the bike cutting out at high rpms. Secondly there seems to be a fair bit of back firing going on with...

    Stripped Thread - Helicoil Tutorial

    In the short amount of time i have owned my pit bike there's one thing i have learnt. ENGINE METAL IS SOFT AS BUTTER! After managing to strip the threads of two bolt holes which hold the left side case cover on, i went in search of a solution to my problems. Big shout out to My67xr he...

    Running hot after 24mm oko install

    For anyone following this, i changed the carb and got similar results with the engine heating so im not too worried about it any more. One thing i did notice was when i went back to the drawing board, i had realised that i installed the white little piece that keeps the throttle cable seated...

    Running hot after 24mm oko install

    I did the valves again to .004 and .006 engine still runs hot but i do notice when i screw the air fuel screw all the way in the revs rise high and drop when all the way out. i believe its about one and a bit turns out now. Im going to chuck the molkt i had on it back on to see how hot the...

    Running hot after 24mm oko install

    Ill give it a crack later, might re do the valve clearances again. Starts easy but was one kick with my molkt opposed to two or three now. I'm thinking of changing the clearances to .004 inlet and .006 out. Would this be a bad idea?

    Running hot after 24mm oko install

    So what i did was, i installed it and didnt touch anything. The air mixture screw is at the stock setting and it seems to be okay maybe a little bit of hesitation but not much when snapping the throttle. I havent touched any jets yet but i did order a #38 & #40 as well as a #104 and a #98. Air...
