HondaCB650

Swapped out the Hagons for some nice stockers that I previously had on the bike. These are CB750 shocks and are 13" long. I set them on the firmest setting and it really changed the stance, look and feel of the bike, plus gave me some much needed clearance for the exhaust. While we were in ther...

Well....I thought I was done. After watching my Dad (who is a good bit taller and more...substantial...than me) ride the bike, I'm really concerned about how low the muffler/exhaust hangs. He managed to drag the bolt on the slip joint already. The exhaust sounds amazing, performs well and whatever c...

Took it for a short test ride, topped off the tank, and returned home to check the plugs. After being satisfied that it wasn't too lean, I rode up to my Dad's work to let him have a look at her. Between my house and his work, it developed and oil leak on the RH outer valve cover bolt. Same leak that...

Well, I determined it is possible to change the main jets on the bike. A bit of a PITA, especially the #2 carb bowl, but it's possible. I had one....ONE screw on the #2 bowl that I thought was gonna mess me up. Finally got it out and I replaced all the screws with allen head bolts, just in case I ha...

BTW, those pics are from early in the build, just to show you what I'm working with. The bike is done, tank and seat mounted, etc., or else I'd just pull the carbs again.

How big of a deal is it re-jetting with the carbs on the bike? I don't know what's worse, R&R'ing the whole rack, or fiddling with the carbs and bowls, upside down, on the bike. Carbs are VM44A on an '82 engine, in a '71 CB500 frame. I need to go up on the mains. http://i190.photobucket.com/albu...

Another thing that worked better after a little heat in the engine and carb tuning was the tach! I'm getting almost zero noise in the signal now. I still need to program the speedo and make a change on the main jets, then figure out what to do about the side covers. Other wise, I'm ready to put some...

While the K&N filters respond well to carb adjustments, they interfere with the side covers. The RH side is worse than the left. I'll have to re-examine this. I could run Uni pods, but I'd rather make these work. http://i190.photobucket.com/albums/z189/uberkafer/CB650/P4160016Small_zpsbe2b8262.j...

Got the seat back from the painter today. Re-mounted the seat pan. I think I might have to come up with a better form of attaching the seat to the frame. Our method works but is a PITA. It's really a 2 man job. Luckily, it only has to come off about once a year for valve adjustments. http://i190.pho...

That's exactly how I have it now. I just need a bigger capacitor. I'll probably wait until the tank is off again and fix it then.

It's not the resistor I need, is it? I need another capacitor to filter out the noise. To clarify: With the tach wire ran directly to the coil, the tach read way too high. I believe it's made for single input. The CB has a wasted spark, 2 signal ignition. The resistor got the RPM's reading correctly...

Now that I've soldered and shrink wrapped all that together, would it hurt it I ran one in series?
Do I splice into the tach wire and run another ground? Or can I splice into the wire that is coming off of that capacitor and going to ground....would that work?

I was thinking a "how to" thread with "after" test results (g) They also have cams for the 550 (regrinds) I can't help but wonder why they couldn't weld up a 650 cam and used that "race" 550 profile on the 650 blank. Seems to make perfect sense to me... Just use the 55...

The speedo works, but I still need to enter the proper tire diameter and change it to MPH. I also installed a 10K ohm resistor inline on the tach wire to get the signal down. http://i190.photobucket.com/albums/z189/uberkafer/CB650/P4150004Small_zps549756a2.jpg That got the tach reading correctly, bu...

While I replaced the idle mixture screw O-rings, needle jets and float bowl gaskets, Dad fabbed up another simple bracket to mount the pick-up for the sensor. I found out that the carbs have 102.5 mains in them already, and I think stock is 100. I ground back the tabs on the idle mixture screws and ...
