Hi I'm new here I'm a old timer ,,, x RC model boat builder and racer ,, with lots of Zenoah 2 stroke experience, we can increase our carb bore's ,,,, we also raise the timings Ext 185* intake 165*max on the .26-,29.5 ,can I increase the carb bore on the 200 blasters how about shorting the pipe how many RPM's can you get out of a stock bottom end also are they oil finicky ? I have Morgan cool power on hand thanks Chris
 
Morgan is a reputable fuel company mostly nitro fuel ,, but makes cool power oil for go carts and other 2 strokes I use it 10 OZ to a gal for my gas boats to 20,000 RPM
