Phantom 85

[ImpulseRocket]

I'm getting a phantom 85 soon and was wondering if putting the cylinder on is a pain.

no worse than any other engine with a 1pc cylinder. When fitting mine together initially I couldn't even get the head halfway on because the case halves weren't lined up properly so the studs on each half were slightly mis-aligned with the other side. I managed to loosen all of the case bolts up and persuade it just enough to solve 90% of the issue, and then used a rat-tail file to clearance one of the stud holes that was still slightly binding.

That isn't a problem unique to the Phantom. Had that issue with 2 other engines. Just cheap engine quality control at work.

Great, and I was worried about getting the rings compressed to go in the cylinder

Yeah, that's no different than any other engine. The P85 cylinder has the little bevel at the bottom to help. I installed mine with just my fingers and a little patience.

No not really. As easy as any other. You just lightly lube the piston and cylinder and slowly lower it on while pushing the rings with your finger or a flat tool

When you say, Just got it, how long ago was that...They ran out of V-2s a while back and only have the newest and best V-3s right now.

I am running a V-2 I got last year, you only have to make sure to flip the bottom end upside down and shake out any possible metal fillings still in it, pour a little gas/oil mix into that bottom end and swirl it around a bit and pour it out just to make sure there is no more filings in it,
Check for any inside the cylinder casting flashings that need to be filed off and smoothed out so it does not catch the rings.

From there, just take some 2 cycle oil and rub it around inside the cylinder and on the piston rings and put things together.
