awesome! did a bit of looking around easier to buy it all in one so dont have the hassle of looking around for all the bits ! will buy it now :)
 
mate i have oko 26mm on both my bikes and swear by em
 
If your putting it on straight away from the start I'd say ride ur bike standard once or twice then put it on. That will you will notice the difference. These are one of the best mods I believe. Brings ur bike to life alot
 
i think i have said this before... but buy it through DHZ let them know what sort of engine its going on and they will jet it for you.. it will save you a lot of screwing around and will save you coming back on here asking why its not running right when you put it on... not trying to be rude and not trying to offend buts its the truth really.. i should know cause i have asked my fair share of carbi questions before i got one that was already jetted for my bike...(big thank you to motorman).. also i agree with stubsy ride it with the standard carbi first cause the bike is more forgiving.. then when you swap you will instantly feel the difference in power delivery.. and i also agree with seano1 yet again lol... run your standard throttle until you get used to the power delivery.. i tried running a 1/4 turn throttle on my oko first up and i shat my self.... so i swapped back to the standard throttle..

I love my quart turn throttle n oko setup its sweet lol
 
sounds good !
my bike starts up and idles but when revving after a half turn it splutters backfires and bogs down so i thought i would chuck one on straight away...i did expect it to be jetted and tuned properly before i got it...might be an air leak somewhere. but i am going to take it to someone who knows how to tune the carb and hopefully it runs properly and ill test it out first then will put the new one on. used to ride a crf250 and occasionally my mates 450 so i know power! but sold that last year cause of other commitments so got a mini just for fun !
 
new x4r, the oko should be fine main jet wise... 38 pilot is spot on but the stock 36 can work then just adjust the needle height and away you go...

dont forget to check the valve clearance before anything..
