Yamaha Banshee 4mil motor assembly.

Banshee 4mil motor assembly. 58x115 crank with stock cylinders. My MX hardcore trail port for the 4mil long rod and some other little goodies tossed in.

This really help me put my motor back together even with having the manual

Glad it could be helpful to you.

[@KensGarage1]

Thanks for the video. Yep, it's long but very good. I am not all the way thru it yet but got a chuckle when you said to check for the case dowels. Just yesterday I assembled my RZ350 bottom end, then l looked over there, and low and behold what did I see? I took them out because it's a tiny bit easier to get the 1211 sealant on. So disassembled and reassembled again. Glad to see you are using 1211 sealant which is what I have landed on after several rebuilds.

Thanks! Will do!

I get to see my motor build thank you Herr juggs

[@larrywarner9314]

I put just a dab of grease on the seal and rotate the crank as im trying to install the gear it goes on a little easier

[@larrywarner9314]

Now to be fair not all piston manufacturers sent ligature on ring gaps and other instructions, i personally can say im surprised i bought wossner piston kit for one of my snowmobiles and not instructions at all.

[@herrjugsracing7816]

Oh wow, I haven’t run into that in 25 years.

[@larrywarner9314]

All it is is a dust sheild , i take them out so it gets oil on both sides

[@larrywarner9314]

I pressure and vacuum test every engine I build !!!! Chainsaws , snowmobiles, dirt bikes, any two stroke engine I build gets tested !!! Or I don't send it out the door

[@dennisbrooks186]

I watch anything banshee related haha. Idc how long it is. I've played around with porting, 2 strokes, 450s, w.e. motor I'm on at the time. But with nikasil, I've yet to cut into that. U have cubs renicked after porting? Is there a certain kind of cutter to not chip the port edges nik? I refurb mostly banshees, want to port my 521 maybe.

[@herrjugsracing7816]

They can and will chip. Maybe I can film how I do it. Its way to lengthy to explain and would make an excellent video.

[@dennisbrooks186]

@@herrjugsracing7816 nice man. Yeah 521 ain't one to practice on lol. I'm comfortable working sleeves. So u still use double cut carbide burrs? I need better tools. Foredom coming soon. Been using die grinding with 6" burrs but they hop around too much. Love the video man!!!!

[@georgephillips7408]

I feel like the banshee motor is the best sounding 2 stroke out there besides the older Detroit 2 stroke diesels

[@herrjugsracing7816]

I call the banshee motor the 426 Hemi of the desert.

[@raymondortiz3221]

hi i wonder why my clutch shaft wont go back as firm as yours??

[@matthewalbone4975]

You need to clean up them cases I recommend vapor blast

[@herrjugsracing7816]

I will pass it on to the customer.

[@paullane7489]

Great content! How much power could you expect(rough estimate) from a ported(street play) 4 mil on pump gas? I’m sure you are very busy, so what’s your turn around time on a full engine build? I mean something relatively basic that you do a lot of? Thanks for your time!

[@herrjugsracing7816]

70hp on pump gas and stock carbs. It takes a few weeks to build it out.

[@paullane7489]

@@herrjugsracing7816 got it. Sounds good. That’s pretty quick turn around in today’s environment of parts shortages. I’ll be in touch. Thanks for your time.

[@matthewalbone4975]

I gotta a Athena 144 kit on my 98 yz125 it's a ripper

[@josephmanfredo7812]

Hey Kevin so I'm going to have about 85- 90 horsepower when I'm done building my 4 mil. I see that you cut "every other ear off", so that the gears engage easier or more efficiently. I would love to understand a little more why and how you achieve this mod. Again I appreciate your knowledge and time.

[@herrjugsracing7816]

Makes for a longer open time for the gears to engage. Its a must if you are in the 85-90HP range. If you really are at those numbers your Banshee wont shift at all. If it shifts fine you aren't making HP those numbers.

[@josephmanfredo7812]

@@herrjugsracing7816 Wow Great to know, thats what I'll be doing when I split the cases. Thank you So much

[@josemaria-kx3cm]

great video, ive noticed sometimes the stuff inside the flywheel its just dirt or sand and not broken magnets so you can clean it thoroughly and blow it off 👍

How can I get my cylinders ported by you?

[@6GEARPINNED]

hey man wicked video, but question, im doing a full build atm stock and my stock main trans bearings came out nice and back in but when i go to put my aftermarket ones in with those half moon clips it doesnt fully rest in the case i dont like that. i check bearings have the same markings on them only difference is they are aftermarket? any help would be awesome as im stumped here. Thanks!

[@herrjugsracing7816]

Some of the aftermarket stuff doesn't fit right. You can modify the clip to fit or run different bearings. I have run into that before but get all my bearings from the same place now that fit correctly. If you stay away from Ebay and find a shop that knows Banshees you will bet in much better shape.

[@6GEARPINNED]

@@herrjugsracing7816 thank you for the reply! i acutally got a 3500 kit from bpatv surprised the bearings weren't a perfect fit? they also wont return or exchange the 2 that wont fit. so mod the half moon clip it is! thank you again! now i can keep building!
