No choice for me, the 4-1 is the ticket. Sound is a HUGE part of riding, that is the sound for me. The asymmetry look I also like. Great scooter, one of the best!
That is definitely not a scooter, that is a honda motorcycle with a hondamatic . So what's a called car that has a automatic? A car. The transmission on a bike doesn't determine if it's a scooter or not… it's not a step through design .
4 into 1 is the ticket. The sound is the best. Back in the day I had a VHR 4 into 1 on my 1979 GS1000E Suzuki. One day someone stole my muffler and I had to ride with just open headers for a week or so while the replacement muffler was shipped. It sounded so good I almost didn't want to put the new muffler on. You running your CB750 with the open headers brought back that memory for me.
4:1 all the way! Remember so well when George Kerker made the first 4:1 header back in early 70's for the 750 Honda, they were handmade and had that unique exhaust note so characteristic of his pipes, and they WORKED. Thanks for a cool video!
4.1 all day, I remember back in 72 waiting for a lift off a workmate and this bike started up , it was the first time I saw and heard a cb750 , I couldn't believe a motorcycle could sound like that, 11 years later I bought a 750 F1.
@@BrickHouseBuilds Ahh, very interesting. I thought 3 into 1 but not 4 stroke. A friend once had a Suzuki GT750 with an Apple 3/1. Sounded very much like that with just a little burbble on the over run like that one.........................anyway, sound great.
The dual 4-2 is the one I am looking to DIY now for my zr7 kawasaki...this is the only video I found of someone who actually did it with the sound comparison... I am worried about who could modify mine to 4 to2, and make it sound a bit like a harley!!
@@BrickHouseBuilds I'm in Australia and have just bought a K2 that hasn't run for 5 years. It runs now after carb clean but doesn't look too nice. It's original and not a barn find or basket case but now I'm wondering how much to put into it? Hmmmmm. Over here one like the bike in this video go for AU$13,000-$16,000. That's US$8,500 to $11,000. Fully rebuilt with all new OEM parts here they sell for AU$40,000-$60,000 That's US$27,000 to $40,000
I mean the same can be said with the 4 into 1 as well. On the first ride video I have a cell phone clip in a parking lot that really captures the sound well.
It seems to me the 4 into 1 sounds like a generic modern inline four compared to the 4 in 2. The 2 cans also fit more "harmonic" to the rest of the bike.
I hear ya but a sohc 750 sounds like nothing else even with a 4into1. I can pick out the sound of these with my eyes closed at bike night. All personal preference though
Idk honestly, the 4:1 is "throatier" but it sounds a tad "modern", whereas the 2:1 peashooters have these distinctive kinda rugged notes ! Two styles ! Couldn't chose 😅
🦅QUANDO FOR EM UM ENCONTRO DE SUPER MOTOS , MUITO SE CONFUNDIRAO COM OS RONCO DAS MOTOS SEM SABER COM CERTEZA QUAL É QUAL , MAS A CB750 FOUR NUNCA NINGUÉM VAI SE CONFUNDIR🇧🇷✝️🌎🤠
I had a 4 into 2 on a CB550 back in the 70's and it was OK. But I have a CB750 now with a 4 into 1 Kerker, no comparison. The 4 into 1 wins every time. Just my 2 cents worth.
No comment about the rideability and performance. I have a twin and a 2-1 set up is what I wanted, and I tried and tried and tried to set up the jetting and just couldn't get to ride smooth with soooo many combinations of jets and spacers. Eventually, had to re-install original 2-2 and original air boxes.. Bummer. How come you can get great tuning with BOTH? Not fair!!!
I think that comes down to the quality of the air filter, design of the pipes, and being willing to make changes until it runs like it should. It takes a ton of changes usually. Currently been fighting my XS650 and its exhaust which is a poor design for performance. In this case I have to live with 1 spot where the bike has a tiny hiccup. It has taken a ton of combos
can anyone tell me the type of engine configuration cb750 use? I have a zr7 (750cc also) but it does not sound the same as this, with the bruup bruup sound (4-1 or 4-2) Is this engine have 2 pistons at the same angle and the other 2 at a different same angle? Or does it have all 4 pistons each at a different angle?
@@BrickHouseBuilds the zr7 is also an inline 4, but the difference is the degree angle in the piston arrangement..and that`s what gives yours an brrrup brrrup sound :)
@@BrickHouseBuilds I know that cost has to factor into the decision as well, and original 4 into 4 are hard to find and super expensive. I rode a friend's 76 750 when it was brand new in 76, it was a mind blowing experience!
