I enjoy this channel because we actually see you working on things, and not just a jump cut to the finished thing your making. Also not everything works, and you try different methods of making these parts.

@CafeRacerGarage 3 года назад

I appreciate that, this kind of comment helps me make even better videos that you actually want so a thank you for taking the time to let me know this :)

@DragonSol42 3 года назад

You are certainly not the only one who forgets the small things when excited for a project. Unfortunately I occasionally forget the big things like personal protective equipment.

@quadbuilt5987 3 года назад

I have been really looking forward to this video and once again you provided an awesome detailed and relative documentary account of the processes involved in manufacturing and constructing custom exhaust baffles while detailing the cause and effect relationship of the modifications. Loved it and agree the tone sounds spot on.

@gregmoppett8425 3 года назад

Your timing on this couldn't be better Dan! This "new" 82 Virago I told you I got is obnoxiously loud. 1hr ride and my ears were hurting. In trying to figure out how to remedy that you may have just given me the answer! Cheers heaps yet again mate! Keep it up!

@mikedelta1264 3 года назад

Great vid. I have two CB750’s (big bore) 79 & 81. If the carbs aren’t clean (ie jets deliver same quantity of fuel through throttle range) and haven’t been balanced/synced the exhaust noise is considerably louder.

@ToninFightsEntropy 17 дней назад

I used an app for decibels this way yesterday, and the first thing I tested was the maximum input the phone can register.. Turns out it's not a lot, so I ended up putting my phone in another room, to get readings within its range.

@BOBBER400 3 года назад

@Thewatson77 3 года назад

Great video Dan 👍🏼 Making your own custom baffles is the ultimate way to do it. I think the sound is spot on now. And yeah...I forgot stuff too when I get excited 😂😂

@bez2944 3 года назад

I had the same bike and tried so many things to get it to sound good but nothing worked. I tried all kinds of baffles. Bought some, made some, nothing ever worked. Always too loud. Ended up doing something that seemed wrong, but was the best solution.. i put a cap (round disk of sheet metal) blocking off the exhaust at the tip. Seems wrong, but was definitely the best it got.

@garya3056 3 года назад

I’m no expert but every aftermarket exhaust seems to have the db killer in the end of the silencer and not in the exhaust tube before it? Great looking bike though 🙂

@CafeRacerGarage Год назад

Yeah you can put the DB killer anywhere you want I just put it at the end because it’s convenient, could even run a straight pipe, and just put a DB killer in it with no muffler if you wanted to

Did you wrap your baffles in the end? I modded my baffle with the tabs & end plate & wrapped it but I find it just blasts the packing out. To the point where I wonder if I’ll end up with big holes in the packing where I bent the tabs down.

great video thanks! I just replaced my throttle cables with custom length cables and I had a problem with my throttle sticking.. I had to get the return cable made 10mm longer. Easy way to tell is with the adjusters all the way closed how much "slop" do you have in the throttle, if none or little then the return is the problem.

@observingrogue7652 6 месяцев назад

I don't believe in Loud-Pipes-Saving-Lives, because it's relying on everyone around me being competent and without malice to hit me, or make me fall. Now, as I do my delivery job, with an embarrassingly loud motorized bike, one pedestrian just popped out in front of me from between parked cars, making me hit them & fall. That idiot jogged into the road without looking, like he was walking down a hallway, only looking towards me, AS I WAS HITTING HIM. Then, when we both got up, he claimed it was my fault because I was speeding ( I wasn't), on an ELECTRIC BIKE (It's not). Somehow, he didn't hear me coming, or he was that zoned out. Because of person, my work phone got shattered. And my exhaust isn't pointing backwards, its down, bouncing sound off the ground beneath me. Then there was the other pedestrian jaywalking diagonally with his back to traffic, I almost hit. Instead of loud pipes, I now want strong Dustbin Fairings with a cage & mesh, to cover my bars and front wheel, to ram idiots like these out of my way, and reduce the chance of them making me fall, or damaging anything. I don't care if their heads bounce off the pavement, and they pass right there. I'm sick of stupid pedestrians causing me injuries & damages, then want to blame their incompetence or negligence on me, or give me worthless apologies instead of money. And I wish my bike was powerful & quiet, so they don't hear me coming, freak out, then move irrationally, making me hit them anyway. That's one of the reasons why I don't bother with headlights anymore, unless it's a time or place where I can't see. For me, I'm better off being invisible, and we should ride like we are literally invisible anyway. Not expecting anyone to see us. Anyway. Beautiful bike. Great job building it.
