Hi guys! I just got a phantom v3.

[ReadyBetty]

Yes, I do that with my chainsaw gas. I put it in the red container and shake the crap outta it. Then when I go to pour some more, I always shake it again. BTW, can I chamfer the edges of those intake and exhaust ports with a Dremel?

Your better off with a small hand file if possible, using a dremel you might take it down too much causing problems with the cylinder, you only want to take out any sharp edges that could snag, some people have dremeled and killed their motors by taking off too much.

You really have to be careful how much you take off if you find any rough snags because the inside of the Phantom 85 cylinders has a ceramic lining that is factory sprayed into that cylinder, you really do not want to damage that surface.

Keep in mind Betty that I didn't have to do ANY chamfering on the inside of my V-3 like I did with my V-2, the V-3 is supposed to have corrected that already at the factory but always check just in case,

Whilst I am thinking of it, when you get the motor, take the bottom half and flip over upside down over a piece of paper and see if any metal shaving or fragments come out of it.

It is also a good idea that after you do that, to give it a bit of a rinse out by pouring just a small amount of fuel/oil mix from your gas jug and swish it around a bit and pour it out again...This should clean out any other residue that might be in the crankcase as well as lube things up down there to prevent dry starting it.

When putting the piston with the rings on into the cylinder, I always take some 2 stroke oil on my finger tips and lube the inside of the cylinder first and this will also make sure you do not have a dry start inside the cylinder as well.

Now my question for you is what kind of bike are you intending to use with your Phantom ???

Do NOT use an aluminum frame bicycle as they tend to crack and break when used as motorised bikes.

Use only a regular steel frame or chromoly steel frame.

Thanks! This is really helpful. I believe a lot of the failures come from overlooking these simple things. I was wondering about the dry bearings and bushings, but your suggestion seems to address that. Now I won't use the Axel gear grease, I'll just swish

I'm putting it on on old heavy Roadmaster I found in a junk pile and spruced up.

If in any doubt at all to confirm it is steel and not aluminum, just take a magnet of your refrigerator door...lol.
If it sticks to the frame, you know your good...lol.

You will also need to lose the water bottle holder and plug up the screw holes that are drilled into the frame for that bottle holder as the motor being mounted in that area will crack the frame where the screw holes are,

I know that @Gordy or @ImpulseRocket as well as a few others who have encountered this personally know what to do with those holes so that does not happen to you so wait for Gordy and others to chime in on that before you even try to mount that motor.

That pedal chain and rear sprockets looks like it is heavily rusted as well and could probably use a replacement chain from your local bicycle repair shop.

 

[Gordy]

Dang..that plug is the exact one I got. Will it bang the top of the piston or something? And what is "run it piston port"? And do it adjust squish by using a thicker gasket? I'm a noob. i Don't know much. Lol.

The plug should be fine, but I don't run one because they do protrude a bit.

Piston port is just running no reed or window. Stock phantoms gain half a hp piston port

A sanding drum on a Dremel is how I do it.
