I’m not really sure what you’re asking but I’ll give it a shot. I think the “overdrive” you’re talking about is the raspy sound some sport bikes have with aftermarket exhaust. By using this baffle type you are essentially muffling that high pitch noise you’d hear from cheaper mufflers at higher RPM. Hope that answers your question.
Did you have to make any adjustments to the carbs after adding baffle? I’ve got a Sportster that has open pipes. Got pulled over and chewed pretty good over the loudness. I’ve been looking at these baffles myself to tone it down a bit.
Surprisingly no carb adjustments. I figured I would have to but it ran just as good after. I’d recommend these baffles for your sporty. It dulls the sound without making it sound like trash.
i own an unrestored ‘80 custom exclusive, i prefer the tank on the custom models, they’re better looking than the f and k models. i’m planning to restore this engine but i do not have any experience. have you took classes before to be able to overhaul the engine? i’m 21 and i really want to learn this craft. any advice?
First off, I love that you’re interested in learning about older motorcycles at such a young age. Secondly, I agree with you on the C model tanks. They’re actually pretty tough to find in decent shape. I was never formally trained on any motorcycle related topics. I was a Toyota dealership technician for quite a while and was somewhat trained, but only on Toyota specific components. Everything I’ve learned has been through experience, research, asking questions…but most importantly, failing. Nobody wants to fail but I’ve learned the most from how NOT to do something. Your ability to overcome and learn from mistakes will transform you into a better craftsman than any trade school can teach. School and training is an excellent tool to gain basic knowledge and I definitely don’t discredit that at all. If you have the means to do it, do it. All that said, the best advice I can give you is to take some basic classes (if you have the means) and apply for an entry level job at a machine shop, auto/cycle repair shop or whatever interests you the most. If you stick with it and have the desire to learn you will succeed. Best of luck to you!
@@SignMeUpDesigns thank you very much, you’re very helpful and informative. there’s just something about old 70s to 80s UJMs. they look like real bikes, unlike what we have today, air or liquid cooled engines with plastic parts. i have nothing against it, i just prefer naturally aspirated 4 cylinder simple engines, they’re more beautiful than the modern classics and modern japanese bikes.
last few questions, i hope you can help me. i want to replace the 4 old cylinder sleeves with new ones but i want to keep the displacement stock. could those 4 be replaced? i’m planning to take a vacation there in the States and i want to get my motorcycle frame there to get it acid dipped. could that be done without any problems? and lastly, as a drag bike, have you done anything to your engine? is there any modifications? thank you very much
It’s an unbranded 4 into 1 that came on the bike when I got it. It originally came with a megaphone baffle. The baffle on the current setup is a drag specialties with a simple stainless turn down pipe.
What size did you go with? I have a 2.5" OD on my CB750k7 but the interior diameter is about 2.3" on the caliper. I think the 2.5" OD from Drag Specialties would be too big. But would the 2.25"OD be too loose? Is that a thing?
you recorded before in the shop. then after outdoors. why were you inconsistent in recording audio in the same environment...your test is inconclusive...sorry Charlie but this is a NO-GO!
Love the sound afterwards! Can't wait to get my cb750 running.
If you’re having carb problems, I feel your pain. Good luck!
Very clean bike
Do you have any advice on how to maintain the deep bassy sound but without so much 'overdrive'?

Siiick bike, and great video! GO Bulldogs!

Love this bike
Thank you. It’s still for sale!

Which header and baffle is that. I have a Delkevic 4-1 that I would like to do this to.

2.25”. I measured the same. Once you drill into the pipe and install the set screw that baffle won’t move.
you recorded before in the shop. then after outdoors. why were you inconsistent in recording audio in the same environment...your test is inconclusive...sorry Charlie but this is a NO-GO!
I guess I failed. If you heard it in real life you would agree it’s quieter. Thanks for watching.
