@@Ragz10 thanks bro, I thought so but I wasn't sure. I put one of those ms380 on a phantom and a yd 100 bottom end. It fit perfectly to my surprise. There were on builders saying I had to use spacers and such but I didn't. Haha. Thanks again
@@Ragz10 for now I'm just using the cat box that the cilynder came with. I did try to weld the phantom piece to some pipe kit I got from AliExpress. I'm never welded before so I blew that project. Ha , yeah the cat box is loud but I love the throttle response on that. So for now I'm going with that . They have dirt bike pipes they are using but you'll have to weld and fabricate. I'm not there yet.
Dude,you don't know what you're doing,you have to stuff/fill the transfer ports in the case,make your copper gskt fit first and all 4 bolts go in straight before you force your bolts in,that should go in by hand,omg Wtf,why embarrass yourself with a terrible video of hackery, guarantee you'll have a case leak if you even get it to run.Good luck.
I did not make this to show how skilled I am or how much I know someone was complaining that they never show start to finish on how to do this so I promised somebody I would do this this video. It is really only for one person but anyone can watch it
He wanted an engine right didn't have to drill or change anything about the cylinder and he didn't want to have to tap screws so I showed him this way. There's a lot of different ways to do this but this is the only one I know of where you don't have to drill
Most of the problem was I spent 30 seconds making that base gasket because the library was closed. I in cut it in 30 seconds. I didn't go to the library to make a copy of the cylinder and transfer it onto the copper so it would be perfect. I eyeballed it
@@oldtrip1765well,,, did it this way with a 0.5 mm aluminum gasket and i have 2mm squish,,,, i guess I'm going to have to deck it to reach that squish
😂😂 minarelli won’t hit 12k?? Are you high?? Click the icon beside my name. I’ve got 4 bikes documented doing 15+ k rpm. 12k is built China doll rpm. Can’t wait for you to throw this motor on a bike and show us 12k for 1-2 miles straight. My last 3 video are 15+ for 6 miles straight with gos overlay.
Use a laser rpm counter on your magneto. You will see your true rpm because any other way your counting every misfire. You will be surprised on your real RPM compared to counting how many times the spark plug fired compared to true revolutions and true RPMs
If you don't believe me take your rpm sensor turn it over and see it's error on the back of it it is safe 98% 92% take that 2% * 15,000 then look at the back of the laser rpm sensor where it will say 99.99% accurate
@@gangsterbuilder lol. Again, look at my videos. It’s not my eye telling me I’m revving high, it’s my ear. And also watch the speedo. My tire size (24”), front sprocket (11), rear sprocket (44) and speed will tell you exactly what my rpm is. I’m not an idiot. 15000 rpm is 65.5mph. Hard to argue math
Why don't u just cut the bolts and make studs or is there not enough room to put a nut on I have a ld100 and I want to put a ms380 or ms440 but all I have is a 40mm crank so idk which 1 to get
you'll get better performance if you fill those transfer port shut. if not, it'll become a air tank instead of a air pump.
That's about how I figured it would go when I saw you forget to put the gasket in 😂
Great job gangster,
👽👾👍
Did that leak like a sieve? Not sure that copper would seal there on the lower transfers sticking so far out on the case side
29 mins later were still at square one....
Im am interested in your 660 build also. What bottom half is that. And what magneto? How did you get it to fit?
Never mind I just read other comments thanks
Bro, I was going to ask what kind of a bottom end are you using? Yd 100?
If didn't get response he uses yd100

@@mikedraper453 no problem bro.
Any idea if pipe n carburator though? Thinking of building on e down the road

For a card I'm using the vm22 26mm awesome carb.
So its a yd100 bottom end and ms381?
Does that copper gasket come with the saw cylinder piston kit? Or where can i buy one i really wanna try this
And do you have to fill the transfers for it to run

Do I normally crank out an engine in a few minutes? no! but can I ? of course I can

What cylinder do you use and is this a yd 100
how thick (fraction or mm) is the copper plate for the gasket for yd 100 bottom and 381 head?,,, planning to build one
Depending on your squishy. I like a squishy .6mm to .8mm
@@oldtrip1765well,,, did it this way with a 0.5 mm aluminum gasket and i have 2mm squish,,,, i guess I'm going to have to deck it to reach that squish
1.75 mm
Have link to parts?
Also what carburator and pipe you use thinking of investing in a yd down the road and may do a saw after.
Is this just a plug and play set up ?
Not even close
How's this build coming along ?
Not even close
Mb wrong comment
M5s, not M6s? 380
Chainsaw usually are m5 and have smaller cap heads then m6 cap screws
do you have some body cut your finger nails for you so you dont cut your finger off

Yes I'm always high 15,000 RPMs I've bet at least 2,000 of them are misfires

@@gangsterbuilder revolutions per minute has absolutely nothing to do with Misfire. It’s the amount of times the crank makes a full revolution
