Review on Kinbelle Exhaust Muffler Stroke Engine by Richard Surveh

Was looking for something less limited. Unfortunately mz65 tubes are sold out until May or June 2020. So I decided to try the fat belly whistle. I could choose cdh66 or zeda88. But I decided to try an underdog. With few reviews. This tube came with no problems. The stock screw on the clutch disc wasn't long enough. But I had more time to sit around. I need a better exhaust gasket as it's pretty crappy. I have a pk80/66, high pressure head, thin copper head gasket, G2 style reed kit with 19mm inlet, Dellorto SHA clone, quality bearings, perforated gears, perforated inlet/outlet, windowed piston/linear boost, no 3rd yet th gear, stock CDI, stock clutch disc, stock magneto/sync, 36 teeth. I used to have a poo-poo flex exhaust that was quiet and good for low torque but only got to 35mph and gave up. Once I installed the reed and window the speed dropped to 25 mph. I needed the best material for this engine. As quickly as possible! I ordered this pipe, it came in two days, all the welds are fantastic and it doesn't have a belly seam like the CDH66 pipe. It's much easier on my eyes. The pipe gave me at least 25-60% more power compared to the stock engine with other modifications. I can climb hills without pedalling, I haven't tested my top speed yet but I know I can hit 40mph because I've been cruising through traffic at 40mph. I had to go up 10 points from 0.60 to 0.70 and I still think I can only go up a few points. This whistle added a lot of power at low, mid and high frequencies. Totally worth $55 in my book. Sounds rough and not too loud? But it's pretty loud. If I drove 10 miles my ears would ring. Hearing protection recommended. Or put on a muffler/diffuser. I will only use hearing protection. It costs money in my book. And gave my bike a whole new spirit!
