    Jetting hp carb

    Just broke in my 66cc china girl. It's got a bike berry hp carb and I'm wondering what size jet to get. I dont know if the bigger number the jet the smaller hole or the other way around. Its 4 stroking at 1/2 to WOT and getting wayyyyy to much fuel. The plug is black. Half throttle is faster...

    "Speed limitation 38km/h"

    I'm on my 3rd tank of gas and I'm running 24:1. With the stock nt carb I had lots of issues with 4 stroking and wouldn't go any faster than 10mph. I just bought a hp carb and it still 4 strokes but finally climbs hills and goes a decent speed. This hp carb has a 78 size jet and the nt had a 65...

    "Speed limitation 38km/h"

    26 inch wheels and 44 tooth but it says in the manual that the "speed limitation" is 38kmh which is 24 and that's when it just starts to 4 stroke and not go any faster. Spark plug has perfect coco color and runs awesome before it hits 24.

    "Speed limitation 38km/h"

    Was reading the manual on my china girl 66cc and it says there is a speed limitation on it. I know it's not an electrical because I have swapped the coil and magneto on it. Could it be because it's not a balanced crank? It will top out at 38km/h and not go any faster even down a hill. Was just...

    Engine running slower when warmed up

    I have a China girl 80cc and had lots of issues with it 4 stroking. I went ahead and bought a bike berry HP carb and it runs way better but there is still some 4 stroking at WOT. It runs almost perfect around 1/2 - 3/4 throttle then 4 strokes. I have sealed all of the gaskets with some more high...

    No power when clutch is engaged

    Yea I'm trying to ride it in powerband but it doesn't get there when it's under load. When I give it gas it just starts to 4 stroke. It revs up really good with no load but bad with load, and I'm only 140 pounds so my weight wouldn't really matter I'll try to send a video later in the day or...

    No power when clutch is engaged

    I put a smaller main jet in the carb because it was 4 stroking under load I haven't tested it out yet though but I hope it works
