 It doesn't seem to be a problem. I had it up to 90 today and didn't notice any ill effects.

 A few pics from a local bike night last week. The 750 and 350 belong to a couple of my friends.

If anyone is still surfing this old forum. The bike has shown back up in Chambersburg pa. And was in rough shape when I got it. I've since rebuilt the engine and currently fixing it slowly

This old thread you probably mean, but yes, if you subscribed to the thread with one click or posted in the thread and configured your SOHC4 forums profile to email you for all threads you comment on, then people are still seeing any updates to threads that went zombie mode due to lack of posts.

I have one of those K&N unipods I bought this last summer. I wonder if you can fit it inside the air box as well, I think you might but maybe not. Rainy weather often can affect tuned bikes running individual carb pods adversely if riding in bad weather.

Personally I'm all the gear kinda rider and I've ridden in light rain, don't wanna do monsoon gully washer flash flood rains we get in the summer, there riding in the rain and then there is stupid, I've ridden years ago in a monsoon storm.only traveling a mile through it and I was soaked and freezing cold and riding through 4 to 6 inch deep water abd it was not even the worst monsoon downpour I've witnessed. Sometimes a weather radar app or webpage from the computer with Doppler radar can tell you if you are needing to wait or if you gotta go early to beat a storm, monsoon rains storms here in the desert SW are so unpredictable sometimes you flip the coin and win, often you lose.

Sorry the owner of the bike between Scott and you didn't take better care of it...
Exhaust would benefit from a glass bead or sand blasting if it is bad enough, and then a black jet hot ceramic coat, flat black exhaust  pain has to be touched up often to stay looking good avd won't tolerate outdoor storage like that bike was subjected to... The header pipes merely burned off the paint and then rusted...

That is a Kerker exhaust muffler, right?
I have forgotten all Scott did on the bike and Photo_ucket has been jerks on images for years and years now...
Apparently Scott still has the account with them as they haven't deleted the images or the forum software has retained an image with the nasty banner watermark obscuring all the photos you shared.

Given you rebuilt the motor it has been abused or misused and may have gotten tweaked in carb setting to cause it to run lean damaging the motor and causing the header issues...or maybe that header issue...that's just flat black exhaust paint and it's sins...
I'm not a fan of murdered flat black...
Why did you need to rebuild the motor or was it just a personal choice?
What did you do to the motor when you rebuilt it. It is a term often used and it can mean minimal or maximum work... that's why I ask what all you replaced, machines, refreshed with new or better parts and the like.
Some people say they rebuilt a motor and it was completely torn apart, everything measured and any close to spec or expected to be wearing out before the next time they dig into a motor, around 30k isn't uncommon on the SOHC4 for timing chain and guides as well as any needed freshing up or replacement of parts requiring attention for bikes maintained and ridden regularly.

So, rebuilt can mean minimal refresh or can mean major overhaul and rebuilt to factory new condition or better than factory condition. Some call a new top end gasket set and maybe some valve work and some spray paint a rebuild...

The satin finish was gorgeous initially, try lookei g for Spray Max Urethane spray cans I think they have a satin, not always carried, but it will protect the paint job from spills as it looks like the PO was very sloppy and inexperienced, sometimes you can be experienced and still have an oops that damages the paint.
Good to see the bike again and kudos to you for your work on it and bringing it back to better shape. At least it's still surviving and having someone love on it again...

I did meant this section of the thread, sorry.  I haven't posted in one for a few years now. I'm playing on glass beading the exhaust and and painting it back a nice satin black. Theres a semi local place that does a special type of powder coating called cerakote. It should hold hold up much better then what was on this. And yes it is still the kreker Scott had installed on it. And she still sounds amazing. When I got the bike by complet randomnes. I actually trade a old car trailer for it. It ran but was smoking awful out of the exhaust. I had torn down the top half of the engine leaving the pistons installed  and checked rings and the clearance. Some of my tools were a bit not 100% suited for what I needed. But found the jug to be in good shape. Just needed a quick rehone. I was having trouble finding the right size pistion rings. And went to Facebook for help. And actually found Scott. He directed me to this forum and I found out about the pistons. Someone else has tried to rering it and use .5 over rings instead of 1.0 over rings. I also replaced the timing chain guides and valve seals due to them being worn out. And it had a damaged valve adjuster access cap, most likely someone had the arms in the wrong spot and tried to reinstall the plug or cover? According to the speedo on it there's about 25k on it now. It's got some oil leaks still. I need to reseal the bottom of the motor and I believe the gear selector seal. I havnt pulled the side cover to verify that yet. It's been a very fun bike so far

Hmm how much ring gap did they end up with .5 rings in a +1 bore ? I wouldn’t think the ring tension would change that much ??

I'll be honest I didn't check them. They were brittle and coming off in pieces when I removed them. I didn't check the new ones either, I didn't have the fender gauges and it was a ice box out in the garage haha.

Harley was meaning to pick on ya, just clarifying the terminology for ya so you get the slang we use on the forum.  Welcome to the sohc4 forums. If you haven’t, go over to the new member area and you can copy and paste some of what you already wrote into your intro, showing folks the condition you got the bike in, etc…rewrite what you need. Tell people where you are , how long you been riding, if this is your first sohc4 etc. if you have other bikes no one is gonna hold it against ya, thing about vintage bikes is you need a reliable modern bike to keep you going on 2 wheels so if one needs maintenance or work you got the backup(s) to pick from… if you have lots or little wrenching on bikes and cars then share that too, often helps other to get to know you and welcome you. Lots of good helpful people hang out her and a few curmudgeons as well… overall a good place. Thanks for the update…

Did the cylinder have scuffing from the clearance being way too wide?
How did they fit .05 over rings on 1.0 over pistons?

Thank you for the info! I'm very new to all of this. The cylinder walls were actually in ok shape. They were glazed over but nothing to hateful. The .05 over set up was very loose in the bore. Where the 1.0 ring had a nice snug fit. I would have figured the .05 rings would have had a weird contact patch from being over spread. But everything was ok!

Well, their mistake caused them to get rid of a nice bike, hope you got a steal of a deal for their stupidity. I would not kick that bike out of my shed...

We are talking .02" rounded for us USA folks, I'm thinking the difference visually side by side might be fairly subtle. Doing the math on the circumferance of each bore size the .5mm over rings would have .06" more ring gap aprox in the bore. relaxed on the bench they would look a lot alike IMHO.

Wow, what a coincidence! My gf's father bought a 1990 Fatboy brand new, and sold it in 1995. 5 years ago he was trying to buy another one and went to look at a 1990 Fatboy not too far away from him. Turned out it was his old bike, and had been through 6 or 7 owners since he sold it.

 Sorry. Just now seeing this thread has been revived.
 Yeah, I recognized the bike when Harley S. posted in a FB group. It's sad to see it a little wrung out like that. But it looks to be in good hands now!

 And Holy Crap...25K on the speedo now?!?! It only had a few hundred on it when I sold it!
