Assuming it is shunt, that is probably not much better than stock.

Finally bucked up and bought that regulator. Got 122.5 main jets installed (Equiv to DJ 132 & V&H recommendation) and have 47.5's on order. Pods should be here early this week. Also have a fairing coming my way. Its getting closer and closer.

You still need the needles or it will have a mid range bog if you have a 4:1

Well i will just have to see how it runs. I ride at about 6-7000 ft, and i'd imagine those uni's will be slightly more restrictive than a mesh K&N.

This bike really is not perfect but i'm trying my best to make it a dependable RIDER. Saving all original parts and throwing some aftermarket into the mix.

Painted and wrapped the header and installed it on the bike. Bolts up and clears perfectly, only one thing. It points right down the middle of the bike.

Anyone familiar with this pipe design as to the brand? I may have to get creative with a muffler. Either way, it sounds beautiful. A bit more "high perf" sounding than the old 8 valve.

Heres some pics for now.

BTW thank you for the help Posplayr.

Heres a vid of it running. Don't bash the no pods Buddies drag bikes run unharmed without them.

Thanks looks like a Yoshi Race header; that is why it comes right down the belly.

Look at the pictures I posted and look on the header collector for numbers staring with "SU"

I think they came in all combinations but I have not seen the chrome race header. It should be larger OD down tubes. (over 1 1/2" )

Bike sounds good

I checked it out before painting it and couldn't find any stamping. It does have large down tubes and a big collector.

You dont have any leads on a muffler for one do you?

Thanks

Looks like the Yoshi on my 1150. It came with my first 1150, and I kept it for my current cycle. They don't come up for sale very often. It makes oil changes a bit of a PITA on the 1150. The filter doesn't fit between the tubes, and where it can fit, the oil cooler is then in the way.

Sorry I sold all of mine

Samsonite, give me the OD of the header, I have a nice used Two Brothers can.

Unless you get lucky I would think you are going to have a hard time finding a midpipe and can for that header unless you can find teh whole pipe and they dont come up that often but they do exist. Look at the exhaust that Giablo just had in the for sale section

Yoshi cans are available on ebay in varying conditions. For example look at this pipe. It is Yoshi and it has a similar bend in the mid pipe although this is the older non can style.

This is rough but cheap and you could piece something together from something like this.

To be honest, that header maybe worth more to someone that already has the complete exhaust and wants a backup. I would sell it and use the proceeds to buy one of the new Yoshi replicas in stainless. All the other pipes rust.

On I forgot you are going to have to get rid of that center stand. The street version that clears the oil pan can retain the center stand as well, but you give up some on ground clearance.

[Samsonite]

Yeah i had done some research and found those pipes. Keeping an eye on them. I dont have a problem making my own midpipe and finding a decent can.

I can do without the center stand.
