Thomas

Engine 139FMB 147FMB 4T 72cc

The engine is really nice. I haven't had it running yet. But it is mounted and ready. There was a small tear in the shield by the chain. But we quickly found a solution to that

BTS horizontal engine 154FMI 125cc 4T 4-speed

Zumico GR200. The engine fits perfectly, I had no problems in mounting it to the frame. The engine runs perfectly, smokes from a shot. Fast delivery. Recommended.

Denis

BTS horizontal engine 154FMI 125cc 4T 4-speed

Engine received quickly, there was a lot of oil in the box but that's because of the carrier, otherwise the engine is great, I mounted it on my masai greystone 50 and it's really plug and play, you just have to connect the cables. On the other hand, the double-branch gear selector doesn't fit on the masai greystone and neither does the kick, so I kept the ones on the original engine, but otherwise everything fits perfectly. I'm really satisfied with the engine and with Gmoto! I highly recommend it!

BTS horizontal engine 154FMI 125cc 4T 4-speed

very fast delivery was pleasantly surprised . To the product looks very good exactly as described . Was of the opinion the motor is produced in Taiwan . This is not so product in China. Well look ma times . Will install the engine in a KIKKER 5150 . the current one with the semi-automatic is not my taste . hopefully it has the power of 12 hp as stated in the description .

Nick

Engine 139FMB 147FMB 4T 72cc

I've now tested this 72cc engine and unfortunately it didn't quite live up to my expectations. The top speed is around 50 km/h, which is a little disappointing as I was hoping for more. However, the engine works fine and does what it's supposed to do, so if you don't need more speed, it's an okay choice.

Brian

Complete engine 110 cc

Runs fine, pulls really well. However, I think it shakes a little when you get up to 8000 rpm, so I do not do that. I have geared the moped on the chain, so the rpm comes down. Coming down, but it can easily pull an even higher gearing if I want to go faster. Now driving approx. 85kmt
