Extreme Motor Sports are very common nowadays. And one of the popular to the young and the young at hearts are the pocketbikes(a small scooter with a 49cc motor powered by a single piston),which are fast becoming a favorite racing sports by most father and son tandems. I just recently watched a pocketbikes racing at the Ynares Center in Antipolo, Rizal and I could say even though they’re still young, the riders are really fast and can leaned their bikes in curves just like a pro. I would recommend to those who would like to try these sport to always wear the proper safety gears; like helmets, gloves, elbow and knee pads before racing. Happy racing!!!
Check this out guys. For those of you who had a GY6 engine here are some tips you can do to your engine. Personally, I already done one of the tips, and that is ELIMINATING AUTOMATIC CHOKE on my Geely. And I can say proudly, that I have done it successfully on one single attempt. I even adjust the air/fuel mixture just right. “Begginers Luck” maybe, but It sure put a great big smile on my face.
GY6 Scooter & Go Kart Engine Performance
A lot of Chinese made scooters and go karts are powered by a 150cc engine based on the Honda GY6 scooter engine design. The GY6 engine with CVT (continuously variable transmission) has decent performance for it’s small 150cc engine displacement. It surprising how well of a job a small 150cc GY6 engine can do at moving an adult around on a scooter or even a big go kart. Of course, more power would always be nice, but considering the small displacement of this GY6 based 150cc engine, it really is impressive. Even so, the GY6 can benefit from some modifications to increase performance.
The Honda GY6 based engine found in these scooters and go karts is like most any other internal combustion engine – in that it can benefit from some well directed modifications. This is true of just about any mass produced engine which have compromises that are driven because of manufacturing restraints like time and cost. These compromises usually limit efficiency and performance potential of an engine. Increasing air flow through an engine is the goal. More air flow along with the appropriate amount of fuel will result in more power producing potential. With that idea in mind, let’s look at some ways that the performance of GY6 engine can be increased. (full article…)
We’ll GEELY is actually my ride. She’s a 150cc china scooter of mine. She is also known as Eagle 150. She has a small but powerful GY6 engine. We’ve been using it for almost 4 years now. Going to work/home, run errands, even to the market on weekends. I can say that she is very economical in terms of gasoline consumption. She can run at 35km/liter, with the average speed of 60 -70 km/h. Im not the speedy type, but It can zoomed when the need arises or when you want some thrill. All parts are stock, except for my pulley which is now a racing pulley.
The large space on the front seat has very important role. I can not imagine other type of motorcycle that can handle what that space have to offer. I can put there almost anything, like an LPG tank, 2 sacks of rice, big basket (for market), a dog, water jug, even hollow-blocks hehehe.
Lucky for me, coz there is no major trouble for the time that we are using Geely, except for the regular change oil, and the following items which I have replaced already (front and rear tire, rear shocks, spark plug, front bearing, handle grip, stock pipe, brake pads front and rear).
Im also keeping Kim. Another scooter of mine. She’s a 90cc Kymco Yup scooter. Before, I always ride her, hehehe, year 2001 to 2002. Unregistered scoot are no that hot that time. I always ride with a group, going to Famy Laguna, caliraya, Louisiana Quezon, Lucban Quezon, Tagaytay and just joyriding around the metropolis. But now Kim just stays in the garage, I do start it’s engine from time to time:D
I always browse and join the forum at my favorite motorcycle website, motorcyclephilippines.com, it is where I got most of my knowledge in fixing/modifying Geely and also gained friend from different parts of the world. I’ll be posting some tips on GY6 engines I’ve gathered from the net, which I think might be helpful to my co-scooterist using the same engine. As for now, Geely is recuperating, bcoz she had an open- carburetor bypassed, hehehe 😆
