I was always on my way here, wasn't I? LOL Long time rider here, and lover of all bikes but especially small ones, this is my latest acquisition. I realized about the time that I ordered it from bikeberry, that it greatly resembles a pocket bike in some ways. I've owned a lot of different small displacement bikes but somehow have never managed to slip into the side lanes of pocket bikes or gopeds, although recently in the past year or so my boys both got old enough for me to justify getting really way too far into Razor scooters and MX350's and 650's, all of which we have and all are modded to varying degrees, all of them awesome. Anyhow, I'm here to learn all about the potential that I know is inside this little guy, a bike we've dubbed "Poopsi". Poopsi has already shown near 25mph speeds, but know there's more here. This one's a 50cc 2 stroke, so I know how to do what's needed- I just sort of need to know the what to spend the $$ on. Specific questions 1. what walbro type carb can I put on here for higher flow and adjustability (stock carb has a blocked off air mixture port). 2. Pipes? I'd like to keep it compact if possible. (Might forgo a pipe for now if it's going to turn it into a trumpet) 3. Clutches- do people like to mod the stock clutches or is there something out there w adjustable tension or springs that will raise stall a few rpms? 4. Am I overlooking anything deceptively important like better spark plug? 5. Can you get a TAV style CVT running on one of these?? I'm in Western WA and want the bike to be adult rider friendly (Hills. Everywhere).
