Monster 185 Plus- C max 175 C- Sky 110 S

[Krishna]

Hi Pilots,
What to buy ?
Looks like Monster 185 Plus, 2015 give the best results and fixed his problem with the exhaust est... ( Find technical data attached, page 14 ). Only one question: they have measured trust of 77 at which RPM... 7800 or 8600 ?
I had C max 175 C, 2013 (http://www.ciscomotors.com/prodotti/eng ... -c-175.htm) which show 68 Kg with weight- 16 kg ( Monster has 14.2 and no ballance shaft and cooling, C Max has ). Also C max 175 C show 27 BHP at 8000 RPM, Monster 25 BHP at 7800 RPM and no cooling, ballance shaft.
Sky 110 S- no available at theis site ( http://www.skyengines.com/ ) only 110. Great engine I heard. Will be appreciated for the technical date if somebody has.
So Pilots what to buy...
