Which mods is the best for a Phantom 85

[FrankHorrigan6]

None. It’s…I actually can’t explain. It’s a 50mm minarelli on a bt custom case. Takes normal China doll exhausts and ld heads. https://rmhperformance.com/products/venom-80-cc

Just dive in kid. It's worth it. I understand the exceptions but any grease monkey who buys a race motor and thinks their cool will get no cred from me but a hypothetical kid with the cheapest Amazon kit and some heart in his garage makes it go just 3mph faster or leave just c alittle harder. That kids my hero and I'll treat him like one lol

Also agree on screw other opinions but I urge you to go for it! Take ur time. Set ur degree wheel a million times. Do it. Buy 2 cylinders extra when u can and bust out that dremel!

I fully plan to read up on porting and port an engine, but before I was intimidated, and decided to order a phantom. Now is a different story as I ordered my phantom last October. But after ordering the phantom and hearing all the good and bad of the avenger, I had to have one. I just wanted to know what the fuss was about. That's plenty enough to keep me busy for a while though, so porting my own engine and building something from the ground up is gonna be a little while.

That's interesting. I don't think that's a BT case though. The BT cases have 4 mounting studs on the front and rear mounts. Have you run this engine yet?

Which style of porting are you leaning towards, the more modern style or the older Gordon Jennings style?

It’s a bt. They pair with wali to make them.

I'm not sure. I haven't looked into it yet. It's something I figured would be best to learn before doing it and actually getting practice with what I learned. Just to have it fresh on my mind.

I realize that now. I read the description and see the parts stamped. Is there any warranty available on this engine?

Shares the bt transfers and tendency to run fatter cranks. I however sold it cause I stubbed my toe on it too many times. My current projects include a testa rossa malossi minarelli horizontal and this. Ma bmx cub

That's a wicked build. Did you ever run it?

The cub? I’m beating on it at the moment. Has 789 miles on it. Running Klotz nitro in it.
