I bought one last night when it gets here I'll fire up the saw and the gas welder and see what comes out of the smoke and fire. I'll bet it won't be chrome anymore. I noticed that it comes with a knock off K&N type filter with a stack. I wonder what I can do with that? evil grin.

I'm gettin lazy might be easier than rolling my own like I've been doing at least a lot quicker. should be better than a home rolled.

I ordered one from them the day this was posted by Jim. If there are ways to make it work best, better or worse I definitely am interested. I want to mount it on my slant 50 with a SBP shift kit so I have a really smooth running system. I was surprised to see the filter and stack and don't know what to do with it but may figure something out.

I maybe wrong but I'm thinking a guy can use that mount and V stack with filter on these bike engines with out too much mods. but then I've been wrong before. Mr. lathe might come in handy on it to make it fit.
I also need to decide which bike to put it on.
I need some sound effects of lord vader with heavy breathing

The filter that came with my pipe,same one I imagine,was easy to adapt using the the round plastic grid that holds the foam filter in the original filter.Cut the two tabs off and it Fits right into the chrome rim on the front of the filter.I cut out a gasket but it may not be needed.You have to drill the chrome lid on the back for longer screws and use large washers or a back up strip so not to dimple the lid.Seem to make a difference but probably not too hot in the rain.Ron

looks like you couldn't use the v-stack? you all are maybe going to see some really strange mounting of my pipe and carb by the time I get r done and yea I'm sometimes an animal and I thought that was funny as h$ll and like it.

big $hit eating grin with the heavy breathing and the theme song of lord Vader playing in the back ground with Inna god of davida being played backwards, me cussing, screaming ,crying, frothing at the mouth and having a good time cutting the new pipe into little bite size pieces tearing up the new air filter and Rufus sharping his claws on the rear tire.
It's a great day.

I think I need to thank Ghosto for posting on where to get the pipe I ordered it Monday and got it today that was fast!

I'm guessing by v-stack you mean that nicely machined funneled connector.Ran out of room!I'm thinking of attaching a curved hood on the back in case I get caught in the rain.Maybe act as an air ram or possibly a rain ram. lol.Anyway between the expansion chamber and the filter I feel like I have 20% more power,give or take 5% for placebo effect.Ron

That stack will fit the carb perfectly I relieved the choke bolt by drilling the back side of the stack where the chokes bolt sticks out a little she bolted right on I did put some sciclone gasket goo around where the stack and carb meet.
I wouldn't worry about moisture on the air filter unless there was a toid floater rain storm my airplane has a foam air cleaner and I don't go around the rain when I'm flying so far it hasn't quit, it eats the rain.
I've cut the exhaust pipe into pieces and going to go weld it up here in a little while.
My carb with the stack will not clear the frame but I'm making one of my offset intake manifolds so I can run the stack and air cleaner.
Well I better go to play.
