Pretty sure that is stainless steel. Just painted a set of these and I was surprised to see what looked like stainless.

OK, got my pipes on. I put the 270s in with the 130 pilots. Boy, the pipes sure woke up my shee! Ran great, for sure the power comes on sooner and harder. Shoot, I have had the banshee for 22 years - should have put pipes on long ago. Anyway, riding in the woods behind my house it seems fine. Was about 60 degrees. I don't think it is running rich for sure. Ran it at WOT on the road on the way back and it made a lot of power but didn't feel lean. However, I may bump up to the 280s just to be safe.

Ok, thanks all. I think I am going to go ahead and start with the 270s. I mostly trail ride and there is water and a lot of dust at times so I plan on keeping the airbox lid on. Plus I have some 270s. I also have some 260s but looks like I need to order up a few fatter jets as it looks like I will be going richer, if anything. After I get them in and take it for a run I'll report back on how close they are.

Got super lucky and scored some FMF Fatty's and PowerCore 2's for $100 on Epay. I have owned my Bansh since 1988 and it has had stock exhaust until now. It currently has no airbox snorkel (but has lid on) and a K&N filter with outer wrap. I ride at 600 to 1000 feet and usually 60-80 degrees. I have 220s in now with stock pilot. I have dialed this in over the years and it is right on around 65 degrees. I run 32:1 yamalube R. So FMF recommends 260s with a 30 pilot - stock airbox no snorkel. I looked through the long jetting poll and some people with similar configs look to be running up to 330! But others are running 270. That is a pretty big variance. What do you all think. I was going to put in 270s to start.

My '87 Bansh with stock clutch was doing this bad last year. It had started the year before and slowly got worse. It was harder and hard to get it to release. Checked the adjustment - it was right on. What is happening is that the plates are sticking together even when you pull the lever. I pulled the cover after draining the oil and completely dissassembled the clutch. I used a micrometer to measure the the discs and plates and they were all within spec so I just reassambled it. Cleaning the discs and lightly sanding the plates completely cured the problem. I have owned my '87 since new and it goes through periods of non-use which seemed to have allowed the plates to dry out and corrode at times. ):

Just added a K&N filter and outerwear that fits in my stock airbox. I removed the snorkel from the lid also. Otherwise my '87 is stock (except for some Boysen reads I put in a few years ago if that matters). I am at about 800 feet. I have 210s in now. Is the K&N enough of a difference to have to jet up some? Mostly trail-riding with some water so I plan on keeping the airbox. BTW, I bought my Bansh, new, back in 1988. Maybe a record? I have ridden it a lot at times and skipped years at a time also. Had to rebuild it once when a c-clip in the trans let go but that is it for major work. Thanks. Here is a pic of mine and a friends (We bought them at the same time - $2550 each).
