different way to mount a tuned pipe

Here is what I've been up to decided to try something a little different
so here is what came out of the box

bike that the pipe and aircleaner is going to go on to. notice the aircleaner has a Velocity stack

Here is how it came out a little backwards

some pictures of the carb I got it all backwards the pipe is black but I didn't get a picture of it somehow only the muffler is chrome now it runs good but not as good as it did before the changes. I need to go back and open up the transfer ports as I wasn't sure it would run with the cylinder on backwards but it does so I'll fix the ports later I've got other thing I need to do now. That intake manifold was a pain to make stainless steel is hard to gas weld.
So how you guys like the backwards bike?

missing pictures of the pipe painted and on the bike rear view pipe tucked in nice and close

I like it

It sure would give me the clearence I need to fit a better air cleaner.

I can just see someone giving that bike the double look going down the road

Very innovative....definitely good thinking out of the box....I wonder why it doesn't work as well with the cylinder head "backwards"?

Wow Norm, that looks cool. But I think you shoulda turned the whole engine backwards in the frame then chain the engine to the crank chain ring and run the engine backwards........................

the transfer ports off of the crankcase are covered up a little by the cylinder and I need to go back and match them up I didn't want to do that until I was sure it would run this way. So now that I know it will I'll take it apart and do the grinding to get them to match. I still don't like the intake and may make another one and not use stainless steel what a pain that stuff is to gas weld with out the proper equipment.
I've found that the bike is super quiet all I hear is the intake and with the big filter its a little quieter than than the stock one I think.
I think the cool factor went up a notch and as far as I know no one else has tried this. if a guy wants to do the ram effect all are looking for it is possible with the carb facing forwards. I'll be happy and run a filter I don't need a rock going inside the engine and doing some custom polishing and porting of the cylinder and piston.

I'm wondering if there will a cooling problem with the hottest part of the cylinder not being in front of the airflow anymore?

**Norman** · #8 (**permalink**) 08-31-2008, 11:05 PM

I'm not worried about it if its going to have a melt down it would have already done it as I've been riding it and even letting it set and idle to see what it will do. So far its running fine. The guy in Mo. who does competition chain saw racing/ cutting says he removes all the cooling fins off of the flywheel he said the more heat that the saw will build the better. I don't know about that but I guess he gets it very hot.
I'm not recommending everyone to do the mod that I did I wanted something different. Sure looks different tho.

Its interesting - the manifolding to the pipe looks a little long though, I'd look at that as well myself.

If you are talking about reversing the cylinder and then replacing it on the motor I know at least one person who would be very interested in that being a functional fix because of her specific requirements.

means a lot less welding as well if it works as well as the stock configuration

This is the same pipe I am using and what I have found to be the optimum header length is between 11 and 12 inches as measured from the exhaust flange to the beginning of the expansion chamber.
