Finally a different option for NOI! Time to dust off that SSXL.
This is a cast iron, 62cc, reed valve cylinder kit. This cylinder comes packed with extra ports and a windowed, 2 ring piston. The intake pattern is the same as Peugeot 103/Tomos so reed options are plentiful.
You can snag a cheap Peugeot 103 intake and point your carburetor forward. Be aware, there will likely be some interference with your frame so don't be surprised if you have to do some filing or grinding on one thing or another.
Comes with cylinder, piston, rings, pin/clips, and full gasket set.
