MS460 Phantom 85 Bike 

This information comes literally, at the prefect time! More details coming soon... Thank You!

@@LAHover I have a question if you can help. My Phantom 85 vibrates at high rpm severely. I would like to know what balanced bottom end engine I should buy to make my own. I would use my old Phantom head and piston but need to know what bottom to buy. I am done buying Phantom!

@@pascalolesen5187 hey, so it’s probably best that you balance your own crank… which you can find youtube videos in or ask members in la hovers discord server. For the vibrations, it could possibly be a motor mounting issue so definitely check that out. The phantom 85 motor is relatively fine, mines ran for monthssss, but it has to be rode in a specific way if you don’t wanna blow her up super super quick.

@@pascalolesen5187 keep your bottoms end, balance and true the crank, switch over to ms460 chainsaw and cylinder OR run the normal cylinder with the non window ms460 piston.

Where can I buy a crank stand to try and Tru my own cranks? I've owned the dial indicator and stand for yrs now

I put one together too, did you have any problems with the chain hitting the tire?

Be careful you two. Nel Lusso frames are prone to excessive vibration and structural failure. Nasty frame under speed. My 2 cents.

@@superbro2097 Will happen if running anything over 2. Solution: add a skinny nut on axle(left) and offset it a bit. Will stop rubbing.

@@superbro2097 no but I definitely recommend using the chain tensioner

@@leonardarola I have definitely noticed the vibration😬

Good to know! Thanks for the feedback.

I did the same😂 came at it way to wide way to quick with way to much lean in my turn so I went down quick af

So true... I haven't had any wipeouts on my bike , but on my CR... T boned a deer in 5th gear on a fire road. Lost all the skin on both forearms, cracked ribs and 5 days in the hospital 😭... That shit sucks

Seems to giddy up pretty good 👍 I would say from watching this video, performance seems more than adequate for my needs.

True a fell due to gravel and holes after heavy rain coming up behind a car he pulled hard brakes I had to pull brakes wheels locked up and I went down not a full on long slide but man did my left knee get messed up(road Rash and deep cut also) still healing all now

Gloves, good boots and long pants are the absolute bare minimum for riding anything with a motor. I see guys riding street bikes in shorts and it just makes me cringe knowing what’s going to happen if they lay that bike down on their leg.

They are strong pullers for sure. Not sure how well they will do on long rides yet but I have a good feeling about it.

That will change when you turn 30. Enjoy your youth.

Moterbike Mike here. I 100 percent agree with you.I can't stand tunnel vision when I have a helmet on.🇺🇲🇵🇷

Haha you can hear the difference ❤

I had a stihl fs85 brushcutter/ trimmer that I used for hours on end daily for my lawn business. It lasted over a decade!

440?

50mm is just enough to fit. I'm thinking the same

@@Matthew-wj8cm 54 fits yd

@@mflbikes1870 yes yes. The big bore ms460 or similar

@@mflbikes1870 well I have a 440 with a 10mm bearing, but I also have a 49mm iron bore that came gouged tho seems pretty thick walled. So I've bin meaning to hone out a full mm see what happens. Just don't have a piston for that one.

Just make sure it's not too wide. There is not much room between the intake and transfer ports. I have seen p85 cylinders soon bad there was literally no where for the gap to locate without hitting a port.

@@LAHover you so so right there. Some are simply impossible to fit through. I heard the ms460 chainsaw cylinder is better and they also make a big-bore ms460. It's a 54mm bore some bolt pattern and all.

Just wanting to know what kit you'd recommend to a newbie and bang for buck :)

I did pop mine open and if my memory is correct it had two chambers, but mostly empty. It is indeed louder than my other bikes. I will likely weld up a crud flange so I can fit a silencer.

Ouch! Glad it was a low speed one tho :)

No, just poor timing on my part. I pull in the clutch when letting off the gas out of habit.

Dremel by Chicago Electric from HF. Carbide grinding bits from Amazon and HF. Practice on junk cyl 1st. Then open up your g2 if you can

Intake adaper

Rubber does not do much other than get in the way and cause alignment issues down the road. It might be running too rich. Rich motors vibrate allot. Try dropping the needle (raising the clip) in the carburetor 1 notch at a time and see if it helps

@@LAHover sounds good. It was running a little rich so I did raise the needle one notch already but it still is vibrating so I guess I’ll try raising it to the highest notch (it’s on the second to highest right now) and see if that helps. Thanks for the help man!

Sounded the same, you don't hear the reed tapping but that's about it. Here are the bars, I'm using a lifted steam, also linked below. Wald Steel Handlebar #803 5.25"... www.amazon.com/dp/B000EHYC8K?ref=ppx_pop_mob_ap_share FOMTOR 25.4 stem 110mm 35 Degree... www.amazon.com/dp/B07L9X5ZQH?ref=ppx_pop_mob_ap_share

I have not, but I have heard they are relatively good motors.

I would suggest not windowing it

Maybe find a larger intake and a carb to suit.

I'd say run it without a window and see if you like it. If you do add a window make it a small one.

More pull out of the Saw build, but that might be the carb/intake... Not a big jump in power as they are similar in specs. The Saw build runs allot better though, smoother cruising.

@@LAHover ok cool...so it probably is right on the same lines as the southern comfort CC and the DLH I'm thinking i mean with all of them just stock out of the box none ported... I know that one you just did was so smooth and clean sounding...iv got a CDH PK80 that iv ported and G2 Reed a PHBG 19mm carb a wc80 and a MZ65 clone and it's really strong on a 36t gear Cranbrook like your red one...it's really strong but it's do choppy when it's not under a load at low speed if it stay around 40 it's smooth but it used to be smooth everywhere until i made it really strong and it pulls really good at low speeds it's just choppy when it's not under a load and i hate that...lol...i put my real speed carb back on and it's alot smoother but still a little choppy nut not as bad...

@@LAHoverchainsaw motor sounds cooler, like a chainsaw 😊

For questions about builds the discord server linked in the description can help. Other than that there is a flood of motorized bike video on RU-vid.

I believe the banana pipes to be snake oil.

Needs a stroker crankshaft

You can use a reed without a windowed piston yes. In my testing performance has never gone up without a reed. That being said, I think the MS460 is designed for piston port and does not come with a reed anyways. I don't even know what reed system would fit.

sweet thanks man I'm going to give it a shot when I get the piston because your probably right about those piston ring gaps being too close to the ports, also my engine temp is like 450 to 500 degrees this seems WAYYYY too hot to me my other China doll ran around 250 280max someone told me it's because i have too much base gasket and when you remove one of those base gaskets to get a tighter squish it will make the motor run cooler. Is that true?@@LAHover

@@jarrodnielsen7547 I think the ring gap issue was only on the P85 V1 and V2. Did not apply to the MS460 cylinder or P85 V3.

ohhh I see I'll have to take a look inside when I tear it down, I'm putting that motor on another bike anyways so I might as well look at it while I got the thing off@@LAHover

Power is about the same. Saw Build runs better.

The p85 is such a mess :(

Bought mine for $375.

A lot

@@mflbikes1870 yeah I'm just not seeing that. All the info isn't out there because that would cause a lot of people to lose money 🤷

@@KB_Joys the info is definitely out there, you just need to look harder

The phantom 85 exists because builders were already doing it... The information is not spoon fed to anyone because very few builders have the time AND energy to build them, film the process, and edit a video about it... It a small hobby. Personally I specialize in the plug and play kits. I attempted a minarelli hybrid and failed, so decided to let someone who knows what they are doing build it.

It's possible, good call.
