You are watching: How many horsepower is a 125cc engine
Cr 8.6:1 ~ above yz 125. Ns think this is in line with the chainsaws. 54mm x 54 mm bore and stroke 124 cc3120 xp has a 60mm bore and 42mm stroke. 118cc.These numbers room different, yet I cant check out this counting for 4 fold boost in horsepower.Any how, why don"t they carry out a little tweaking on the saw motor and dual its calculation if without doubt this is all the is different?
125cc modern-day MX motor has actually the benefit of. -Boost ports-Case induction-Reed valves-Tuned pipes-34 to 38mm carbs-Power Valves-Full one cranks-Thin ring pistons
totaly diff engine, water cooled, reed valve, change exhaust valve size, pipe, carb etc chainsaws are really weight limited on what the can do,and size, friend dont desire a pipe and also a huge carb with a huge air box on a work saw
125cc modern-day MX motor has the advantage of. -Boost ports-Case induction-Reed valves-Tuned pipes-34 to 38mm carbs-Power Valves-Full circle cranks-Thin ring pistons
My BIL had a Winchester 70 in 375HH and the only thing we shot v it was a pine tree (pre CAD) and a groundhog, an ext of a novelty around here, I"ve shot a quite few big bores as much as the 50BMG but never got to watch the terminal outcomes in something bigger than prairie poodles, I"ll bet that 500 will anchor lock thar bares!!:msp_thumbup:

Sorry come the OP however when I saw the smoke poles in the sawmans sig ns couldn"t aid myself!.... 2 2 punch smoke and also smokeless powder because that fun, just in America!!!!!
It"s all around heat.It shouldn"t it is in too complicated to get means more power from a observed motor, yet you"ll never have the ability to get rid of the heat without going to water cooling or editing a cylinder and also head through 4-5 times the fin area. Then exactly how will friend shroud everything and also not have actually it be huge. You deserve to probably get similar horsepower numbers from a race saw, but it"ll never have the ability to run for any type of extended duration of time. With a modern-day bike engine you have actually much much more advanced porting, reed valves, carburation, ignition timing, exhaust systems and also of course cooling systems. In my younger days ns raced professionally and also then constructed motors once I ran the end of unbroken bones. I was to run RM125s which i ran the compression in ~ 225 psi v 36mm carbs. Way more 보다 you"ll find in any type of work saw.MP5N

All this is possible because the designers of motorcycle competition motors have....more an are and weight in the formula to work with. No going to broaden into a weimebook, however all things noted so much in this subject are possible in the MX world due to the fact that they have actually the space to work-related in and also WEIGHT constraints enabling freedom in architecture solutions. Starting with cooling...if much more power is to be had..more cooling is required. You have to have some foundations to build on come have an ext power...bore & stroke and the freedom based on casting dimension to have much more port area, bigger transfers, an elaborate intake and exhaust devices such as power valves & situation reed induction systems...etc. Simply goes on and also on...expansion chambers.. I just can"t see a chainsaw solution helpful with water cooling & pan to gain the air circulation as they space static in operations, expansion chambers. 20plus pound motors making 30 plus hp deserve to you just imagine what that would certainly look like? practically like blood"s bicycle saw! through water cooling...
