I'm 14 turning 15 in June and I'm looking for a vehicle for when I turn 16 but I'm stuck between getting a full sized dodge truck, a dodge dakota, or a xj. What do you think would be the best option for me? I want to be able to go mudding and also have fun driving every once in a while during the winter.
Don't use a windowed piston unless you have a reed valve... For the piston skirt a couple milimeters is probably fine but too much will make it just send fuel back out through the intake. At least pistons are super cheap so if you do get it wrong you can easily start again and dial it in. This is definitely how you learn what works for two stroke tuning, experimenting and trying all kinds of new ideas.
you wana sell it lol? And where's your oil fill tube? I'll likely want to keep the elbow setup too and but now with my 302 the fill neck hits the CAI so getting the cap off is not as easy as it should be.
Smoothed ports? Polishe exh port leave intake rough textured but smooth widen ports also for air flow don’t raise it much then drop to a 41t sprocket and punch holes in the carb cap remove exhaust cap and cut that tube off the cap leave 1-2 inches… works pretty good better than banana lol mz65 or the clone of mz65 is what pipe ya want unless ya modify a actual 70cc dirtbike pipe or jog pipe
Get a shit chrome,steel hub rear wheel ,then weld sprocket to it, also my Dawes frame has no need for horrible chain rerouter, that make bad vibes, also rubber mount exhaust,these three things will make your bike not fail, probably catch fire instead !!!
Clearancing the piston on the bottom does nothing because air and fuel isn't drawn in on the bottom of the piston, it's drawn in on the top were combustion takes place. I get that you're trying but really..... know WTF you're talking about before making a video to inform or should I say misinform others. Anyway keep it up and eventually you'll get it right. 😁👍
Good job on getting in to porting. These cylinders are a great way to learn because if you mess up, they're only $20. On my old flying horse, I left transfer timing the same, hogged out the port itself with a good top blend and matched the deck using the gasket to transfer the shape. I raised the exhaust 1.5 mm, widened it 4mm, and on the intake I widened it 2mm and lowered it 1mm. I shaved the head too much and it hit the piston, so I ran a thicker gasket until I had 0.06 of squish. I ran a manic mechanic intake and opened it up as much as possible, and ran a SBP exhaust with a wider diameter stinger. These mods aren't perfect but the bike would CRUISE at 40-45 with a 32t rear sprocket and topped out at 58, HP limited top speed. I also bored the carb as much as possible, probably only 1mm, and re-jetted. It smoked the clutch pads after a week and blew up after about ten tanks of gas.
I’m currently experimenting with a flat top piston and it’s excellent on paper but I still have my doubts. I can always save up more money and buy a piston in case I mess up but the ideal piston for these motors for me (without any scientific data) would be one with a skirt, a window or two on the intake side, and or a flat top to prevent blow by. If I were utilizing the videos I’ve re-searched over again for video comparison, I’d probably ad a ramp but I’m still looking around for information on the topic to increase overall power.
I just bought two of the dio Reed engines. The intake ports are so small it is ridiculous. They are half the size of a stock intake port. I know it needs porting I'm not sure whether to go up down or both.
As far as power the pipe and carb is the # 1 power adds ya can do the porting determines speed and can effect torque and other aspects but getting ya port timing right wit the pipe or modi g the pipe for ya port timing is key to max piwer
im almost crying while watching this he actually grinded down the head and now theres not gonna be a good seal :( im almost crying jesus christ dude like i get you wanna learn stuff but before you kill yourself do research
lmao wtf that cylinders mint just buff that out and use it as a third transfer port. Will need the windowed piston with the oko carb. carb pilot jet needs to be drilled and you need a real good expansion chamber. then it'll have some real power. these motors are all about the tuning not the parts.
Mirror polishing the face of the piston and combustion chamber helps too. Especially when you're running high compression. It resists carbon buildup, which will keep your compression from getting too high over time, and it'll help prevent pre-detonation (pinging/knocking), by preventing hot spots. It also think it makes the engine run a little cooler, because it reflects heat, making more of it leave through the exhaust.
