"Avenger 85 Motorized bicycle Exhaust manifold Fix!"

[@MotorizedChuck]

I also own mega Phantom 85v3 engines. Warning: remove the studs, chase the threads, add thread locktite and reinstall straight. Change the lock washers. Check your squish gap and adjust for tighter squish which will reduce heat and longer wear. Also chase and stud the exhaust

[@RaoulDuke224]

Didn't have to do that if you go see some of my videos I pimped out my phantom 85 it's called the super phantom menace 85

[@MotorizedChuck]

Hands down, the Phantom 85v3 is x2x that of the Avenger85. However, the Phantom needs to be gone thru to make reliable. Especially inner case cleaning, inner case flash and case seals

[@RaoulDuke224]

already did that

[@DirectCurrent4u]

And don't forget to balance and tru the crankshaft! 💯👍

[@RaoulDuke224]

@@DirectCurrent4u that I don't have to worry about

I have an avenger 85 and also exhaust problems. 5 gals fuel and pulled the top end off. Slight transfer champering intake scuffing and smoothing and exhaust polishing and raised the exhaust port by 0.4 mm. Also the exhaust had flash casting on the outside of it causing exhaust soaking flange from the monster pipe that welded onto the stock outlet. Filed on a flat sander smooth and also filed the exhaust flange at the port New gaskets I want my squish .65 to .8 tops and then rejet the carb

Good stuff

[@RaoulDuke224]

My phantom motor you see I did work on the cylinder head and the inside with sand paper and hand polished aluminum so no more piston rings snaging

[@RaoulDuke224]

As for the avenger 85 you need double exhaust manifold gaskets

[@MotorizedChuck]

@@RaoulDuke224 "Rings" snag? Unless I have an updated version, (doubt it) it has a single ring and unlike the phantom piston, it is a single ring. Also it resembles the hs272xp design

[@MotorizedChuck]

@@RaoulDuke224 I just did some transfer shaping. I believe it will really breath more efficiently but smoothing out the sharp ramping inside the transfers. Also it has only 22° blowdown so I raised the exhaust. 2mm

Looks awesome brother ride safe

[@RaoulDuke224]

Thanks 👍

[@skipstalforce]

Yep, I been wondering about that suggested oil gas mix. You see BBF muffler fell apart? Maybe them two gaskets can help with that also by reducing the vibration alittle. Thanks for the info Raoul!

[@RaoulDuke224]

Yeah I am what you call a thinking man always problem solving stuff
