Re: Where's Waldo of carb parts...

Look on the side of the carbs for an imprinted model number. These aren't Keihin VB44A's are they?

He should have VB44A carbs--presuming his bike still has what it left the factory with.


Yes, I have the VB44A's.

Re: Bogging when cold

Sounds like a work around for choke plates that don't close all the way. Have you had them apart to visually inspect and make sure they operate smoothly and close completely?

Re: Carb clean; accel pump

I got annoyed, trying everything to get the accelerator pump bowl passageways cleared. I used a small drill (1mm) to drill out the brass block and try to pull it out by threading a screw into it. I had previously found a tutorial that stated the block was plastic; that proved not to be true. Under t...

Re: CB650 Custom Side Panel Badges Wanted

Are those the traingular ones like the '81 or the rectangular ones like 79? There are a few on ebay if you're not too picky. Some of the prices are stupid. IIRC, I replaced my missing one for around $30?

Re: Carb clean; accel pump

Finally ordered it. Shaft size is quoted as 89mm. I measured mine, it's more like 1.75" or 44mm. Guess I'll be cutting it down. Should arrive Monday. When I cut it, what's the 'spec' on length? Is there a specific clearance between the lever that depresses it, or is it just "make it the sa...

Impatiently waiting until 10am Tuesday when the dealer opens to find out if I can order one. Until then, looking up aftermarket alternatives just in case.

Re: Carb clean; accel pump

Here's a pic of the accelerator pump diaphragm/shaft from my #2 carb. I assumed it was a fixed and unmovable mystery part until I read up on it. Finally took the accelerator pump bowl off without losing the spring, tapped gently with a mallet, and realized it had been frozen in place with rust. No b...

Re: Testing pictures

This is my accelerator pump shaft/diaphragm. Think it's still serviceable?

Re: Carb clean; accel pump

I just found this PDF about accelerator pump bowls on the 77-78 CB750. Is the diffuser in the middle plastic or brass? I was under the impression it was brass but now I'm left wondering... http://www.hondachopper.com/garage/carb_info/accelpump_valve_repair/Repairing_77-78_Accelerator_Pump_Valves.pdf .
