Removing the restrictive emission control from the skyteam ace should improve performance and tidy up the look of the engine. Let's not worry about the environment at 125cc.
Tools required plus the OORacing 'EGR Cylinder head exhaust emission blanking plate'
Remove the tang that holds the pipe to the air intake by hand. Remove pipe.
Use small pliers to remove this copper adapter.
0.22 inch threaded screw or bolt will fit nicely into it's place. May be imperial?
Screw in with small pliers.
Remove emission outlet pipe with a kex key.
8mm ring spanner to remove the mixer part of the emission control device. The metal tangs that hold it in place are flimsy and may bend if you apply too much pressure. Once unbolted, you can pull the entire device out - the outlet pipe on the other side of the bike will simply slip out with its sleeve.
Keep it for reattaching for roadworthy for resale.
8mm ring spanner for the OOracing 'EGR Cylinder head exhaust emission blanking plate'. Do not over-tighten.
Much neater. Perhaps faster?
