So im confused. Is this in the case that i just need to do maintenance on my engine after a few years and I just need a new head or is this an entirely new performance upgrade by having the intake and outlet offset😅 or is it none of the above. I’ll be honest the only problems I’m having right now are in that there’s not enough air going to the engine but then again I think it’s because I used too much oil and not enough gasoline for the engine because I used a 40:1 mixture as per the instructions…
I'll only answer to this: The 40:1 is the minimum for most.There's Allot of videos(Duh,right?),that argue for more or less.I ran a cleaned port,(Just Flashing,and tiniest of bevel so the rings don't catch),with gaskets to match for 3000+ miles at 25:1 and then went 32:1 for the next 1k.Water in the fuel caused it to Pop and wedge offset when I stupidly listened to "Add a fuel drying additive in cold weather".It absorbed water...
@@bryduhbikeguy i was told to ride and die 24:1 i think. Like that that was the thing to go for… i’ve already done plenty of miles so im gonna use up the rest of my fuel and then chnage 40:1 to 24:1 - 32:1
You could never polish a port enough to stop turbulence. Yes your eyes and fingers tell you it's a mirror finish, I get it. To fuel and oxygen molecules, there are huge mountains the size of everest to bounce off of all along those port walls. Yes, smooth is bad, but smooth to us means absolutely nothing, we can't even fit through the port. Ask an ant how smooth your mirror finish port is and he'll ask, how high are you?
Nice video Toney, I have that exact Dremel kit you showed been using it for a few years. I used it to Port & Polish my first build, And it did a great job.
I see and think that I understant the why's of porting intake abd exhaust ports on t he 49cc 2 stroke engines. What I'd be interested in is there anything to be done to 49cc 4 stroke engines that is worthwhile.
