thanks cactus, i think that could be the problem coz i have played with the float level before. i'll give it a try this weekend and let you know how i go. cheers for that

Hi guys i've posted before about having a problem at WOT. It just won't clean out and bogs and splutters. i'm running the stock carby in a 140xr pitpro with a uni filter and a 105 main jet. the bike runs SWEET 3/4 throttle and below but after 3/4 its absolute shit. i checked what...

Hi guys i'm still having trouble with my pitpro 140xr at WOT. pretty much 3/4 throttle and below is perfect, then going past that from 3/4 to WOT and the bike splutters and bogs, it doesn't die though, just won't accelerate anymore...like it's getting too much fuel and not enough air. i had...

thanks for that guys i'll have a look tonight. up or down, which way is lean and which way is rich?

sorry it's a pitpro 140xr

Hi i've got an 08 pitpro with a uni filter and a 102.5 main jet on the stock carby (30mm mikuni). the bottom end and midrange is awesome, but as soon as you open it to WOT it bogs and splutters and doesn't clean out. i've heard heaps of people talking about adjusting the e-clip but i...

gday, i've got an 08 pitpro with unifilter & 105 main jet. its always taking so long to start the bike and i don't know why that is. could it be the valve clearances? i've only ridden it about 10hours all up since buying it new. it will take so many kicks to start, whether full choke or...

I've got an 08 pitpro 140xr. everything's stock apart from a unifilter and 105 main jet. It starts when it's cold after a few kicks and full choke but after riding it for a while with the engine warm/hot it's hard to start again. I have to empty the fuel from the carby every time to get...

cheers for the part numbers in the earlier threads cass i'm going to order them tomorow at the moto shop legend

No worries man, i'll let u kno im getting the oko 26mm keihin rep carby next week from maylands so could be in the same boat as you.

yeah but isn't the stock mikuni on the 140xr a fake? that's what i've heard...don't know if it makes any difference if it's fake or not though. i'm taking the carby apart to night and taking the jet to the moto shop to get a bigger size so no biggie.

Hey guys I’ve got an ’08 pitpro 140xr and I’m going to buy a bigger main jet for my carby (stock 30mm mikuni). I want to buy a 102.5 and 105 main jet, but don’t know what brand to ask for? I’ve read in similar posts that mikuni and keihin have totally different sizes and I don’t want to...

cheers man i'll go find out about the jets from my moto shop and wait for 'the spoon' to help us out with the filter size legend

well sounds like the oko 26mm carby is the go. is that the flatside carby? also, the stock carby takes a 40mm uni filter...will this be the same size for the oko carby? and where can i buy bigger jets if you know? pitpro?

cheers for that motoxxx but if i start messing with the air/mix screw on either carby (oko or stock), wont' that mess up my revs below 3/4 throttle that is fine? i've read that just changing the main jet size can fix this problem? i will probably get an oko carby, but if i could fix...
