More top end on your two-stroke

Hello fellow Motorbike Builders!
I have a couple two-stroke Motorbikes and like we all do, built it stock, when I first started building Motorbikes! With a few simple modifications I went from 18 mph in stock form, to 42 mph max speed! I took the Head off, then the jug. I used a Dremel tool to grind the intake and exhaustports larger to .080 total…. .040 on all sides of the jug. Very simple process. I purchased the big round head, The Extreme cooling head, Bike Berry sells for $74.95. WELL worth the money$$. For best results used Bike Berry‘s expansion chamber muffler they sell for $69, it works the best, stock pipes are to restrictive! The bike runs so well that I used Bike Berry’s 30 tooth sprocket, and sprocket adapter, the Aluminum one that clamps to the rear hub. Yes 30 tooth! Very nice piece! Works really well! I have tons of power, torque and top end speed! 42 mph Max to date. Thank you Bike Berry! Ron McAteer
