make sure to grab a 1.5m gasket to properly space this kit out!

I am passionate about getting everything out of 50cc and this kit gets you set up to do just that. I have actually drilled and ported out 2 sub exhaust ports next to the exhaust with plenty of room to spare. I also closed off the intake piston port with some JB weld because I have the ADDY aftermarket case and have switched to case induction. With this case, porting, 21 mm delorto style carb, 17/38 gearing, and a modified proma circuit exhaust, I'm hitting top speeds of 54mph consistently and daily drive this 20 miles to work and back every workday. I love this kit!

e50, timing set 3mm BTDC running HPI mini, 16x40 hit 42 GPS Speedo, 170lbs man child not bad. Techno exhaust running 15.15 sha 78 jet, running slightly rich with is better then lean i suppose. edit 1, installed claw shoes and brace and baby does this kit rock, low end still sucks but mid to top end is crazy. pulls like a 2 speed, gained 3MPH from clutch running. My kit tops out at 44 now, avg 38-40
edit 2 topped this kit out at 48mph gps, put about 300 miles on it, ended up taking the kit off as it just way to much of a dog off the line and throttle needs to be pinned constantly. If you're looking for a nice boost over stock with a good mid rip/top tip this is a decent kit, if you need low end look away. My verdict on this kit is just go with the airsal 44mm gain some low end/speed But with that in mind use martystoolbox and calculate your rpms relative to your gearing. this will keep your bushing nice and happy.

My Series B with a 14mm bing 80 jet and 15mm #1grandpa intake 18 degrees TDC, techno circuit pipe, I'm averaging 29mph and top speed is 40 with 16/45 gearing. I don't have to peddle off the start anymore. My bike is in the power band 100% of the time now, so nice. Bought a second for my sons bike for Christmas, crazy cheap upgrade. This is what you want if you have a kid and want more power or also have a motorcycle and want your moped to have power 100% of the time.
