intake

Ok so I've shaved the head a bit and ended up increasing compression. I read somewhere that you can shave some of the exhaust port to increase top end performance? Is this true? If so how do I go about this. I've already dremeled the intake manifold so it's the exact same size as the port. It...

On the case reed engine I have to change the rubber hose for one with a 45 degree angle. The silicone hose is longer which would allow me to move the carb farther back from the seat tube. I just don't know how this will effect the engine. Will it make more torque like a non reed engine or do...

To work properly? I'd imagine pretty straight but. Mine is slanted towards the front of the bike now because of this intake manifold and the way the motor is mounted. I'll go ahead and start drilling the flange at the motor for a better angle and check back here for any info from you guys. Thanks!

First all hello. I'm a brand new motorized bike ower. I have a two-stroke mounted to my Trek frame. I have been fixed everything I can on it and have now tackled performance. I bought it used so I don't have any history on the bike other than what I have learned that was wrong with it after I...

Whether it is on or off, fuel goes through. I can run my bike in the off position. So because of this, fuel can freely go through when the engine is off and I can't do anything about it. Will this hurt my bike or is it fine?

The air cleaner was in the way of my leg, so I came up with this idea. Turbo hose. It works perfectly.

Hi guys. Little back history. I have a roadmaster mount fury 24 inch frame with a black 80cc china girl. The engine clears so far but i have some issues that i wabt to touch base with. The lower tube were the mount is, is rather large and the bolt holes dont match up. I could squeeze the frame a...

Does anyone here know what the proper torque of the intake and exhaust studs are? Im in the process of replacing them. Id rather use a torque wrench to tighten them down just to be on the safe side.
