Hey guys
I’ve been running my new bike in recently (pitpro 140xr) and it’s been running sweet as…until the motor starts to get warm/hot and begins to splutter and lose power from ½ throttle onwards. It’s especially predominant when going flat out in 3rd and 4th gear.
I’ve read through various threads and think that the main jet might need to be bigger? I’m running the stock mikuni carby (30mm I think?). Does anyone know what the standard main jet size is? Also, where can I get a bigger one and what size should I run?
Could it also be a CDI/electrical problem? Or will this be fixed by moving the e clip up one or 2 positions?
i think the bike is running a bit lean (hot engine, can't keep the high revs etc.) i havent' checked the plug yet, but i will tomorrow.
Any help would be great fellas
