GY6 50 High Performance Racing Carb
26mm Carb for Performance GY6 50 engines with at least a 50mm piston plus larger exhaust header
Performance Exhaust is needed to run a carb this big with a 50mm head and cylinder. You will move a lot of air with this carb but this can put over 50 all the time easy with plenty of torque if CVT is tuned correctly with 6gram weights, performance variator so it is not restricted like stock and at least a torque spring at 1500rpm then of course a performance clutch does even more.
There was no difference I could see from a no name stock GY6 150 24mm or did this carb do any better. This was after a whole race season.
For me if you really want to use a different carb I suggest a 24mm TM Series Mikuni. These are four stroke carbs used on motor-cross bikes.
To use you will need a taller manifold. Since I do not get very many Naraku spacer I use a Teflon intake and jack it up with stock plastic spacer sometimes double those making them larger with dermal tool.
I see no difference and it did not perform and better than a no name brand and the so called Keihin carbs I have used in the past on the very same bike with the same jetting which was 95/98 45 pilot.
Larger Intake needed plus intake spacer for best results.
Use only with larger 50/52mm heads. All other heads will have to small of intake opening to handle this carb. However the intake spacer will help since it can be reversed.
This is a 24mm carb, stock is 18/19mm so its quite larger. Larger intake (chrome) or Teflon Coated intake will be needed along with spacer to replace the black plastic one in stock engine.
Carb is only used on engines with 50mm - 52mm Heads.
This carb will not work correctly on any other head or a stock engine and is for upgrade only.
This carb may also be used an quality replacement carb for GY6 150 stock engines with no large intake needed.
SRC scooter racing crew will uses this carb on number 09 which is 85cc with pipe and racing head.
We have installed this carb on our 50=52mm big bore kits along with new intake and spacer/riser and it works great and adds all around performance.
