Exhaust Tinkering Part 1 of 2

A few seasons ago, I re-installed the original 4 into 4 chrome pipes that came with the bike when it was purchased new because I wanted to paint the 4 -2 - 1 pipes that were flaking badly and generally looking terrible.

I loved how the 4 mufflers looked from behind but was not crazy about the additional weight. They must have weighed about 60 lbs and I noticed that the engine didn't quite rev as freely as when I was running the 4-2-1 exhaust.

I finally got around to painting the exhaust and reinstalling them and was reminded how much I disliked the exhaust note.  There was a hollow ringing sound that I didn't like when blipping the throttle.

Since I was re-installing the 4-2-1 exhaust I had to hear it without the muffler just to get a baseline and it was definitely too loud for me, but what was worse, it seemed like the engine was a little more sluggish and resistant to revving.

Then I came across this youtube video : https://www.youtube.com/watch?v=vPet-q6F5jA&t=132s

I found one of the baffles for about $15 shipped and shoved it in there to hear the difference but it was still too loud so I left the baffle in place and put my canister muffler over the baffle and discovered the hollow ringing noise is gone and it now sounds pretty terrific.


I think this baffle configuration will allow me to install a resonated exhaust tip in place of the exhaust canister for a short custom look.  Maybe next year.

After running quietly for a few weeks, I replaced my canister muffler with a moroso spiral flow muffler because I had it sitting around for years.  The baffle makes the exhaust sound pretty good with this free-er flowing muffler so I'm going to run this for the rest of the riding season. It's louder but not obnoxious.

Universal Speedometer/Tachometer install

I wanted to replace my original speedometer and tachometer for something more compact. I'm not sure why, but the original 85mph speedometer always bothered me. I guess I felt like the bike deserved better even though I've only pinned it once in 10 years of riding.   After casually looking around and almost pulling the trigger on a cheaper universal speedo with an analog sweep needle for the tach, I stumbled across this product. It can be found in all the usual places such as Amazon and eBay but it's usually buried behind 2 or 3 pages of search results with vastly different prices ranging from mid 40s to mid 80s (US$). The description typically includes a listing of what each wire is intended to be connected to, but in typical fashion for these kinds of imported products the English translation leaves a lot to be desired. For example: the product detail notes: "Oil Quantity Indicator" as one of the display areas, but they really mean fuel level (my bike doesn't...

how to open your door when neither handle works

My recently acquired 2003 Honda Accord EX 4 cyl had a faulty door lock actuator in the front passenger side door.  Here is a run down of what I did wrong in case you find yourself in a similiar situation. Shopping for door lock actuators - Prices go from around $10 to over $40. I mistakenly ordered a pair of door lock actuators ($20 for left and right) for a coupe and received 2 black actuators that were not sized correctly for my 4 door sedan which has smaller white actuators. I did not discover the problem until after I had the door panel off and the actuator removed from the door latch assembly. It was hot, the flies were landing on me and drinking my sweat and I just wanted to button the door back up and stay cool inside so I searched for the closest parts store that had the part in stock and went there to buy it for $45. (I did return the 2 wrong parts but did not get a full refund, but I'm ok with that...$16 back in my pocket is better than $0) Reassembling the door l...

Nighthawk CB750 rear wheel swap part 1 - decision

I've always had a very slight side to side swaying sensation in certain conditions that I was not able to pinpoint.  It was especially bad back when I had a trunk/top case on the back of my bike.  An old timer on a forum noted that the tall rear tire mounted on a 16" wheel can get a little wobbly (concerning a top case causing 'sidewall flex, by increasing the leverage on the vertical axial moment of the bike') and that pretty much got the thought in my head to swap the rear wheel to a 17" or 18" at some point. the 1979 cb650 would have been an easy and cheap path forward since it's pretty much a direct swap to a 17" wheel with the advantage of the wheel design matching my front tire.  Unfortunately, those wheels were not cheap and getting more expensive by the day. I found 2 or 3 listings on ebay and was looking at a minimum of about $90 to get one shipped to my house and then I would still need to clean it and swap out the bearings.  Since I...
