Back to stock(ish) part 3

First ride with the original carbs after about 1 year and the seat-of-the-pants performance meter indicates that the cb750c is sloooow.

I'm sure my performance meter needs recalibration after riding around on the new Street Triple, but I'm pretty sure the old girl was not this slow with the gixxer carbs.

I'm sure I need to do some troubleshooting, maybe check for intake leaks or pull the carbs and see if anything is wrong.

Otherwise, with the standard mac mufflers she sounds angry.

Loud, slow, and angry, but I love the way she looks and like the riding position.

I'm going to continue riding her this way looking for any opportunities to get her running the way she was meant to run.

Had 2 fuel leaks after re-installing the original carbs. #4 float valve was leaking and now appears to be sealing after dropping the bowl and fingering the floats. Then #2 bowl gasket was leaking because the gasket got pinched on reinstall.

Seems like my choke is not doing the fast idle but doesn't seem critical as she seems to be warming up ok with just the throttle.

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...
