HGC Red Air Filter & Muffler Exhaust Pipe & Carburetor & Intake Manifold & Carburetor Intake Manifold Fits 49cc 66cc 80cc 2 Stroke Engine Motorized Bicycle Bike

OK gas bikers here is the scoop on these items. As you may know these cheap hp knockoff carbs are not plug and play. Actually a SPEED NT carb is better with no mods. On my last 66cc install the kit came with a Speed NT carb. I tried (drove) this with the HP carb first with the stock jet then I tried (drove bike) with the SPEED carb.With this HP knock off I was 10km per hour lower than the Speed carb.I swapped jet from the speed carb to the HP carb and gained 5km per hour but still not as fast as the stock no mod SPEED carb.I kept the NT carb on the 66cc and on my next bike a 49cc I used the HP carb.OK on to the Muffler. These bananas are only made for a a low mounted motor. I mount mine high so I can use a pull start as it must clear the peddle swing. Otherwise the muffler gasses will discharge at peddle/ peddle bearing level and oil up your bike frame. AND this banana will only clear a smaller front frame down tube. Not a Huffy cruiser or any front down tube greater than 1.5 inches without hammering in the muffler in the spot it hits the front down tube. In my case the muffler is worthless and I use it as a bugle and a bad one at that

The only thing I didn't care for was the muffler would hit my peddles do I had to ,with a hammer, dent it enough so I could peddle. Other than that I a swapped out the air cleaner for a bigger one I allready had. It fit perfectly.

the carburetors ok that's ok the muffler went right in the trash exhaust straight my back tire just what you need oil brakes

The carburetor was totally different than what was shown. The air filter didn’t fit the carb that it came with or the stock one. It’s like they just threw what was laying around in a box and sent it to me. The pipe however works nicely. Wish I had bought just the pipe for half the cost. Now I’m stuck with this carb that fits nothing

Exhaust kinda ok carb junk never could get it tuned in right or something factory carb would almost stomp it
