Shineray 200XY IV / Roketa DB-27A Exhaust Mod

[john25]

I bought a pair of Shineray 200cc dirt bikes a couple of weeks ago and couldn't believe how quiet they are. I pulled out the exhaust tip/spark arrestor and found what was essentially a PLUG with holes drilled in it.

Had to fix this so I went on ebay and found a vendor that would work with me in trying to find a bolt on spark arrestor tip that would fit. The tip that we found bolted right on like it was make for the bike. It's actually made for a Yamaha TTR-125. Check it out on the bike.

The bike now sounds much better, but not loud and it is a screen type spark arrestor. I know I am going to have to rejet, but I am in the process of modifying the airbox and changing out the stock air filter set up out for a "real air filter". Here is the ebay link for this tip.

wish mine had that kind of exhaust on it when I bought it.

of the subject, but if you ever need to replace that rubber mud guard, treadmill track works really well.
