What kind of pipe is this

[Jordancaird]

It's says Riva Yamaha on the manafold

 

[Big Kahuna]

Factory Pipe Type 4 Dry Pipe or Riva Freeride.

 

[Jordancaird]

OK thanks so much man

You might want to turn your air inlet around, looks like it would direct water directly into the carbs.

Looks like my Riva pipe.

Riva Freeride Dry Pipe - its a great pipe as long as you have the mounts and pipe to head seal in place!

 

[CHRISRACERX]

That looks sharp with the red pipe and accents

Agreed! How does it compare to a Factory B pipe?

Agreed! How does it compare to a Factory B pipe?

More mid to top power, less bottom and throttle response.

 

[TheBuzzard]

More power top and bottom if set up correctly on a good motor. B pipe is more reliable. That's it.

 

[Jordancaird]

Dose anyone know how to get the bottom inside manifold bolts out I'm pretty stupid feeling asking that one but there is no room for anything and I'm stumped

Remove expansion chamber from header, then remove header and engine assembly and work on it outside the ski. Easiest way even if it doesn't seem like it up front!

 

[Jordancaird]

OK so u my gave been rite on the out side the ski thing lol cuz I've ripped that Lil rubber boot from the mani to pipe dose any one know what this is and the size I'm gunnar need

 

[Mobile Chernobyl]

Yea another step I forgot to mention is that after the header is on the engine outside the ski, place the engine in the ski then slide it forward to put the chamber. This will make your life much easier than trying to do it all while the engine is bolted down! Same is true in reverse.

 

[Jordancaird]

Ya I did it OK in side but now I need a new rubber boot thing dose anyone hAve a measurement for that rubber boot that connects the mani to the pipe
