My custom Header, Finished Engine Build. What Do You Think?
A while back I bought a Rossier for 70 bucks, guy didn't know what It was worth so I offerd him 70 for it, it was Brand new never used yet just did not have a Header... So I thought about paying someone to build me a header and everyone wanted an arm and a leg to do so. So I bought some mandrel bent 1.75 Exhaust Swan Bent tubing for 30.00 bucks and made my self a Header what do you all think? I don't ride in a lot of wet conditions so I'm not to worried about the Rust, but would be nice to find a way to keep it from doing so. Only time it gets wet is when I wash it but usually start it right after so it don't stay wet long.
I just did a Complete rebuild as well my mods are below because I know some guys may be curious just out of Typical male mechanical affection.
So far it Seems to Perform amazing I'm really impressed, not sure if it's the Cam and Big bore my Porting job that is making it pull so hard, Can't wait to get it on the Dyno because. It's hard to explain but it almost feels like you're going to lift off the ground when accelerating lol and I was shocked that it pulled on my buddys 06 trx450R that has Racers Edge head Job, stage 3 cam and green wire mod! Shocked the **** out of me because Inever expected mine to be as quick as it i now.
So the mods I have.
480 Big Bore "Cylinder Works Kit For now running the Vertex Piston"
Stage 3 Hot Cam
Epoxy head "Done by me"
Kibble White Springs
Kibble White Valves

2 layer Cometic head gasket
Hot Rods Crank

Rossier Muffler with my Own Header
I did my Own Epoxy Job, not the best in the world I know and of course I may get some hate on my Epoxy job but I reshaped my Intake and I also epoxy'd right behind and around the Valve Guides in a bit to make more of a casual "turn down" to the Valves, Most importantly I raised the port Floor with a bit of a Casual "turn down" as well. I made it to where the air/fuel charge hits the Valves directly at the same angle as the Valve.
