Honda CB750 Cafe Racer Part 2 - Delkevic 4-1 Exhaust system unboxing & fitting

[@carltonolson6813]

That 4 into 1 looks insanely awesome on the CB. Keep the cool videos coming.

[@forthebold]

It does, thanks, more CX videos this Friday

[@gabedini]

At the start of the video I was skeptical I'd like the look, but that exhaust is mean looking, nice work!

[@forthebold]

Thanks, I was happy with how it turned out, better than I thought.

[@Jbailey9102]

This is my exact bike. Just only halfway through it runs and is built now to work on all the minor details I wanna do to it

[@forthebold]

Enjoy. Best of luck

[@xsp9615]

that is a good looking exhaust ! on my cb750 nighthawk, its a 4-4 exhaust, a total nightmare because im trying to transform that into a good looking 4-2 using the oem exhaust . keep on the good work and ,as always, have fun doing it .

[@forthebold]

Thanks and good luck with yours, this purchase was definitely worth it.

[@benhawke7231]

Hey when you paint the engine, you should polish the tips of the cooling fins and put some really thin masking tape over the polished tips. That makes the engine really pop.

[@forthebold]

That and functional also, it's pretty much a must do if you're painting air cooled engines as the heat needs to escape, undecided yet with what to do to the engine. Waiting for the customer to decide.

[@kevingrandke6075]

That is a nice set of pipes! I will have to order those for the 82-CB750 I am doing

[@forthebold]

They are good

[@Mstrndizguyz]

Is it designed for just a straight pipe or does it take a silencer also? After watching this I bought it also, but only a straight pipe came with it. Is that the way it is designed. I then ordered jets from 6sigma.... 120 main and 78 secondary. Plus running pod filters.... it needed jets to match the air flow. 1982 cb 750 k

[@forthebold]

It’s designed to take the delkevkc 63mm silencer too. Only thing I’d say is to use K&N pods too. Any cheap brand is just like adding water to your fuel

[@Mstrndizguyz]

are you saying a silencer instead of the straight pipe, take off the straight pipe and add the silencer?🙃 And by the way , you are an inspiration to my work on this bike. Its my first attempt and I'd be honored if you would look at a couple pics and add input. I can email if you like with my thought line and the direction of this build.

[@MrJuancarl0s]

hello how great your videos !! I would like to know if you can help me? I have a 93 cb750 nighthawk and I would like to put a 4 in 1 tube like yours! where can I get it ? enter delkevic but there are no cb750 models

[@forthebold]

You could contact them directly

[@obliq4037]

Hi! I'm going to bought the delkevic 4in1 system for my cb750f (1981) but I want to install a reverse cone in it. Where have you found the link pipe? It's not included with the 4in1. Thank you

[@forthebold]

Delkevic had it for me

[@kbowen2251]

That exhaust looks fantastic! I do have a small suggestion for ya though from my days working at a car factory. There are silicone ring covers you can get to wear over your wedding band so it doesn't scratch or dent the metal and/or paint. Cheap and really worth it in my opinion and that way you can keep your band on. I can't wait to see where you go with this build though!

[@forthebold]

Thanks and thanks for the suggestion, I'm always paranoid that if I take it off I'll lose it.

[@kbowen2251]

I know the feeling! I have a tungsten band myself and with some of the work I do I keep a silicone cover around just to keep from scratching or denting something. Should be able to find something on amazon and then you can keep a baggie of them in the shed haha P.S. electrical tape can work for now as well

[@forthebold]

good thinking, hadn't thought of electrical tape.

[@kbowen2251]

Only thing about the tape is it will need to be replaced frequently. That's why I still recommend the silicone cover.

[@mhamusic.]

4 to 1 was definately the way to go on this. Looks really good! I have a question regarding my first build. I have no idea what to do with the crankcase ventilation system! Should I buy one of those filters that just clamp on to a hose and leave it at that? What have you done for the GS550 and CX500? What do people do, generally, when building cafe racers or scramblers? Doesn't seem to be much info on the internet about this. Thanks so very much!!

[@forthebold]

I know what they're there for but as for when I'm not 100% sure. The best thing I stick to is if your bike has ventilation pipes don't block them, use filter pods, if the ventilation holes are bolted up, I leave them

[@TheRyanweyh]

Love that exhaust. Gonna be fun to see that bike transform

[@forthebold]

Thanks, it's going to sound nice.

[@TheRyanweyh]

For The Bold - dreegez for sure !

[@chrisbruins21]

Looks great ! I'm building a 82 750 F. Just curious if the exhaust leaves room for a nighthawk oil cooler from the filter cap? Was leaning towards carpy's but after seeing this one it looks great and seems like a little more affordable price point ?

[@forthebold]

That’s a good question. Not sure about the post 80 models. In fact not even sure about this one yet. I’m fitting the exhaust this week again with the oil filter on. I’ll let you know.

[@chrisbruins21]

Awsome thanks I know I asked delkevic but they didnt really get the question. But they did say the 900 and 750 are the same and I think the CB 900 stock came with oil cooler.

[@zenpro8164]

not only looks but equalized scavenging is the most important in which needs to be mentioned for increased performance

[@forthebold]

Absolutely.

[@88nastase]

Please tell us how do you solve the problem with the pod filters and the jets...

[@forthebold]

First would be to get decent pods, go K&N, never the cheap ones.

[@88nastase]

For The Bold - dreegez this could get the rejetting problem solved?

[@forthebold]

You will still need to re-jet, always, but it'll make your life so much easier, Pods are around £170

[@88nastase]

For The Bold - dreegez ok.thanks a lot for your answer. I'm working on a cb400n. Not the best bike to start,but that was available. Nice job with the videos!

[@forthebold]

It's a very good bike, all the best with it. I'll be doing a video next week on K&N vs cheap pods and issues, rough guide is 15% increase on the main jet size.

[@paulmaddison2507]

I wish you had should how to fit them very very short strong springs?

[@forthebold]

It’s in a video later on towards the end of the series.

[@dennisdalhuisen1519]

Hello, Which muffler are you going to use on this? The endpipe is 2,5 inches. I could not find a suitable muffler. Thanks for your help!

[@forthebold]

Delkevik do muffler to fit this also

[@page188]

In Brazil, this Bike is very rare and expensive. But, the engine is the same as the brazilian CBX 750. So I bought one and am now buying some parts. The project is a bit more difficult to execute because the CB is more "ready" to become a cafe racer than the CBX. But I'll be starting the tear down proccess this week. Would you mind take a look at the CBX 750 and see if the original gas tank will be a problem or will do? Thank you very much, apprecciate your videos. Since my bike is monoshock I already bought a dual shock and will install.

[@forthebold]

They're pretty rare and expensive here too to be honest. Good luck with yours. Without actually measuring I couldn't say if the gas tank would be an exact swap, but you can fabricate frames etc to fit.

[@matthilley]

11:00 "The weather should be getting a little bit nicer at the end of February" haha.. tell that to 'the Beast from the East'

[@forthebold]

I remember this time last year I was sat out working with my laptop!

[@nielsoostveen4816]

Looks good! Can you do a cost thing for this bike too?

[@forthebold]

Thanks, unfortunately as it's a customer bike I can't, if it was for myself I would. Sorry.

[@outsidethelines8502]

I was just going thru some old papers and found the owners manual for a 79 CB750K that I had a couple of years ago, let me know where to send it if you want it. It's in good shape, no charge.

[@forthebold]

Thanks thats very kind of you, fortunately I have a workshop manual but thanks for the offer

[@stancoleshill8925]

I was going to ask why you were going to remove the engine. Looks like it has been outside for some time.

[@forthebold]

I always do. You can’t properly do a proper job on a rebuild or custom job without removing the engine to both clean/fix the engine and powder coat the whole frame.

[@rmulchi]

Looking good man! It’ll growl now. Next month I’ll be swapping my original rusted 4 into 4 on my cb750 with a 4 into 1 from Cycle X. This week is rear sets!

[@forthebold]

Thanks, all the best with yours

[@MrNDboi]

what muffler did you end up with? i ordered the same header system and need to figure out the muffler part still

[@forthebold]

Just open end

[@raywhite7934]

hi loving the builds, was wondering if you were planning on any modern front end swaps as I'm hoping to do this on my z550.

[@forthebold]

Thanks, no not on this build due to the cost being too high for a front end conversion.

[@brucekirk5386]

My 4-1 hits the ground bottoms out the collector was badly smushed but I built an entire exhaust system when I rebuilt her.

[@cranky1812]

It's a really good exhaust but I think 4 into 2 would have been better for top end performance and esthetically pleasing.

[@hisaanhaq4116]

Id love to hear your thoughts on the exhaust fitment, i have a different bike gsxs 1000 but your review brought me here for the delkevic, like what you do 👍🏼

[@forthebold]

I like it. There’s a video later in the series of actual fitment and sound.

[@nunpuiazahkhar]

Hi, i could'nt find the video where you lift the fuel tank. Can you please find me a link?! Ill be glad

[@forthebold]

I'm afraid there isn't a video like that.

[@nunpuiazahkhar]

Ok. Thankyou... Sorry about that 😅 i must have mixed up with someone else's video

[@007mercucio]

The pipes I just got came with silicone exhaust sealant... when do you add that? And where? Do you let it set on the pipes first? Apply it wet, and slide it together then? Can you just skip it, entirely? Anyone?

[@jamiegreen8065]

Install at every connecting point that doesn't have gaskets. After connecting, twist till you get the correct angles then let it sit for a day before starting up.

[@forthebold]

Yep. Install at every point.

[@jait8399]

How much weight?

[@daved2783]

Have a gs850 project bike, where is a good place to get an engine rebuild kit?

[@forthebold]

There are a lot of gasket kits out there on Amazon / ebay, suzuki dealers, then I guess depends what part of it you want to rebuild? Piston rings, valves, big end ...

[@daved2783]

For The Bold - dreegez I want to go to a 70mm bore, motor is a little tired. Just need a top end kit/gaskets

[@williamknutson7468]

Now do a video of proper carburetor tuning for this exhaust...

[@forthebold]

Already done. It’s in the series

[@jeffreywilde203]

You look like a friend of mine who is a cofounder of Rag & Bone: Marcus Wainwright. But youre you! Anyways thanks for the video. Got a Delkevic system for xmas for my 1977 Kawasaki KZ650. This gives me an idea of how to go about putting the exhaust on. Did you have to fabricate any sort of exhaust mount?

[@forthebold]

I even got mistaken for someone elses son the other night, by the father himself, I think I have one of those faces I guess. No fabrication needed, the exhaust system is a direct bolt on providing you order for the correct bike.

[@jeffreywilde203]

@@forthebold Ive heard its tricky aligning the pipes to the collector. We shall see. Thanks for your help.

[@Supersvein82]

Spring in february?! Not in Norway! 😭

[@forthebold]

Well, late Feb, March 1st is officially the start of spring here.

[@Supersvein82]

Ok. I hope to get on the road by mai 1 st, but we might get snow. :-)

[@SrgBlueBalls]

Does anybody know if this exhaust also fits a Honda cb750 KZ RC01 '79. can't find it anywhere. Thanks

[@forthebold]

This is that model. Apart from the Z bit

[@amazing_ray]

Seems to be pretty warm in the UK 😎

[@forthebold]

That day was, surprisingly 12 degrees centigrade, can't complain for a January.

[@rumble_doodz4067]

im in the middle of converting my 84 cb700 into a cafe racer will this exhaust work with the 700 vs 750?

[@forthebold]

Hard to say, I'm no exhaust expert, best check with the manufacturer as I'd say a lot are universal.

[@quangnguyen4408]

How long does it take you to finish it?

[@forthebold]

I give a year for each bike, but I only spend about 3 - 5 hours a week on them

[@forthebold]

Search Delkevic and you'll get to their site

[@connoroguinn9573]

So i'm curious, what muffler are you going to install? I was looking at cone engineering or just doing another brand of a reverse cone. Have heard anything good or bad about reverse cones? Also your channel is awesome! I binge watched most of your episodes in about a week!

[@forthebold]

Thanks. Glad you like it. I’m going for a Delkevic muffler to fit straight on

[@BigOmni]

Did you buy just the down pipes and the link pipe for Delkevic? I contacted them and they told me they will only supply the link pipe with their exhaust and that’s don’t supply it with just the down pipes. A shame if the case 😔

[@forthebold]

I did get the link pipe in the downpipe kit, could it be different for different bikes?

[@BigOmni]

For The Bold - dreegez - my bike is a 1980 CB 750 with DOHC. Did you get it from their eBay store or direct from their website? Thanks again for taking the time to reply 👍

[@forthebold]

I got mine from their ebay store, shou;d be the same kit as mine.

[@BigOmni]

For The Bold - dreegez - Thanks. I have messaged them on ebay again. Let’s see what they say this time 👍 Just sourcing some GSXR 1000 forks and triple trees for mine at the mo.... hopefully some come up 😀

[@BigOmni]

Well they are still saying on the eBay store that they will not supply the Downpipes and the link pipe 😢 I get this reply..... “Hi There, The link pipe is not sold seperately as it is unique to the Delkevic silencers. The FULL system can be found on these two item numbers:272874931357 or 272017718102 where all of the necessary components are supplied. Hope that helps, Thanks.” Did the one you got explicitly say downpipes and link pipe or just downpipes? They are also not replying on the website which is a tad annoying tbh. I may have to find another manufacturer 😞

[@forthebold]

We weren't sure what muffler to add and the ones they had on their existing kits were too long for the look we were going for, but we might get the 12" muffler so it doesn't poke out too long and have the removable baffle for the straight through system.
