Hey guys I have a Sebring bike that I picked up off my friend . He said he did some upgrades to it, but I am not sure how much he actually did. Overall it does pretty good and I believe I can get it to maybe 30-35 mph on a downhill, but I don't have any idea because the speedometer/odometer doesn't work. I have been doing a lot of research using these forums and going all over online info for the morini M1 engine and how to increase performance. So as far as I know The bike has stock everything. So the (1) first thing I did was ordered the Mikuni vm18 carburetor, a UNI air filter, and a new intake that is compatible with the vm18. I would like to know if this is a good decision in putting on the bike for better performance.
(2). I had a bad experience with a crappy Chinese gy6 engine in the past while doing a big bore kit and never got it to run and i am skeptical of taking the next step of kitting the moped especially since i've seen a lot of people saying that porting will need to be done to make sure that the parts fit. my second question is which kit could I get for the best performance that will take the least modding, and can anyone help me with said modding if it is complicated.
(3) Which tuned pipe should I get for the sebring (morini) that is under $200, and why should I get that specific pipe.
(4) If the bike still has the old speedometer and it does not work what do I need to do to get it to work.
Thank you for your time and consideration.
