This may be blasphemy but you could always track down a nice 4-1 exhaust setup that is used and in good shape until you find can put down the cash for the real deal.

Probably could find a good used one for $200 ish.

I think that may be an option as well. Hmmm. I think I have a nice 4-1 kerker not being used.

Well since I had to buy my stock pipes and restore them and there is nothing structurally wrong with them I want to run them. It's 4-4 on this bike or nothing ;)

I almost always prefer the 4-4 pipes even on a cafe, but on a stock resto like yours anything but a 4-4 is a lesser option.

I agree, this bike needs stock 4-4.  Unlike Danny, I prefer a 4-1 on a cafe.  It would be boring if we all liked/had the same bike/exhaust.

so here are my headers.
these are the two worst #3 and #4





here are the #1 and #2 pipes. this rust is only on the headers, the rest of the pipes are pretty good actually




moving on. I was assembling my gauges, I bought new gauge wiring harnesses from yamiya. the speedo harness came with the 4 lights etc. and a yellow wire and a black wire. the yello with male bullet connector and the black with a female. there is clearly nothing to plug into in the speedo....so I am assuming these are extra???

Yeah, those pipes are toast.  If not rusted through and dented, have you considered getting rechromed?
Plating has gotten very expensive, may not be worth it.

I've heard that chromers wont touch pipes because of all the crap inside them. if chroming comes out to be $500 I am definitely just going with new pipes. I'd like to do benjies 4-4 pipes but I've read that they interfere with the centerstand. if I can find this to be untrue and they fit JUST like stock, I am going with them...roughyl $1200 and all stainless steel construction...sign me up.

I think I am just going to run these until I find something better or spring for new ones. I just can't afford it right now

Chef- soak the header and just the header in CLR. Then get a steel wool 000 pad. They won't gleam but the rust should come off. My #1 header is rough but I rather have a rough one then not be able to have 4-4s.

I was at the Honda shop wed after lunch to see the 1100 and send my wife on a biz trip to Atlanta. A pair of younger sales reps male and female were the only ones to talk to my whole clan. The one said he owned a 350f but had sold it. My wife got them talking and told them about my bikes. I couldn't resist and asked if they had seen a man with a handlebar moustache buying parts! Yep!!  I told em he just put the engine last night I saw it on the internet. They were impressed for sure!! "you tube?"  Better link them up to your build.

So, the strategy is to lie to people you are asking for help?

I think I'll be busy going for a ride.

Good luck!

Another less popular option is to scuff them down and hit them with high temp black. doesn't look like you will hurt them any.

I do not have the extra wires on my wire harness for the gauges. Weird. I would call if you paid good money for them to find out what they are to?

Yes, they are extra as the yellow and black wire is used on the CB750 Japanese market bikes. It connects the speedometer over speed device (#12 in the diagram) to the red warning light in the upper triple tree. Since you won’t be using this feature – it can be ignored. No worries.

Aha I had a feeling that's what it was for! But I haven't seen ANY on us models, only a few on YouTube that were Japanese models. Thanks!

Browns will plate exhaust pipes.  They plug the ends before dipping into copper, nickel and chrome.  http://www.brownsplating.com/  It won't be cheap.  I'm guessing rechrome will cost as much as a new set of repro pipes.

That's for the link Scott. I'm trying not to spend more Han the pipes are worth because if they rust out from the inside no amount of chrome will make them "work" better. I am currently saving up for a new or repro set. Going to ride mine as is. I'm not at a computer so I can't upload my pics, but I got my front brake working. The only thing old about my brakes is the caliper body and the 3 way intersection between the forks.

I put dot4 in the system and slowly pumped and got bubbles out. Installed y
Speed bleeder and then followed some advice I read here and attached a 10ft hose to the bleeder and sucked through it for a good but to get fluid right in the system faster Than pumping it for hours. Seemed to work well. Then I kept the lever pulled in and the bars to the left to let out any bubbles overnight. Seems ok. I have NOTHING to compare it to at all so I don't know if its spongy. Walking the bike around I can stop the front on a dime with only 1 finger and about 3/4" of movement.

I put the seat I have on it and with the lowering blocks I am going to be able to tip toe around and stop with my left foot down at lights. I think It's manageable. I might buy another "cafe" style seat that's thinner to use and hold on to an oem one.

Front brake should not be spongey at all.  Plz post a pic and info on the speed bleeder, been wanting to get a couple.
Do you really need the lowering blocks?  Pin shipped today.

thanks Stev-o! I took the lowering blocks off and it made almost no difference. I can still only stop with one leg off to the side with a stockish seat. cant really even tiptoe walk the bike though. oh well. I read up on lowering blocks and how they put more stress on the shocks than necessary because the angle is different. I think I will leave them off. I do want new rear shocks though. really want to stick with stock look. DSS has a pair I've got my eyes on

also, the speedbleeder I bought is part# SB10125-SS. its an M10 x 1.25 thread and its stainless steel. it was around $10 I think. bought it on ebay. fits in perfectly. the hex head is 11mm though, kind of throws off the whole 8,10,12,14 thing going on with these bikes.

Hey Justin may be dumb on my part but have you made sure the lowest sitting setting is in the shocks? I'm 5'9 but really short legs and I touch easily on my bike.

An option may be to buy a repro ducktail seat on eBay for 144. From the looks it sits lower then the stock non ducktail.

hey Nick, yes I do have it on the lowest setting. I have REALLY short legs ha. I want a ducktail seat badly but the only real one I like is the one yamiya sells for $1100, ha. I am thinking about buying one of those foam and cover sets and shaving it down. but I still need a better pan and I need a K1 hook and safety catch (according to the fiche there are two hooks). got my coils in place, and my brake light switch, horn. going to start routing the harness now.
