Topic: CB750 specialty tools

[hotelstationery]

I just did a valve adjustment with regular automotive feeler gauges and after I was finished I thought there must be a better way.  I would love to pull the valve cover right off and do them but I'm guessing that the cover won't come off with the engine in the bike.  I Googled CB750 valve adjustment and saw these nice feeler gauges from Z1 Enterprises.

Naturally I'm going to order two, in case I lose one.  Since I'm going to the trouble of making a postman carry it all the way to my house I thought I would order some other things at the same time, especially specialty tools that are either required to maintain my bike or just make life much easier, such as the feeler gauges.  What would you recommend, assuming I have all the normal hand tools such as sockets and wrenches.

I've seen this carb adjuster mentioned on the forum before, is it a worthwhile tool?

They have two different vacuum gauges.  Does anyone have either and care to comment?  Since one is quadruple the cost of the other I would expect some significant difference.

Do I need a clutch holding tool?

Or a clutch hub spanner?

Any other thoughts or ideas would be appreciated.

Clutch hub nut tool is a must to work on clutch, that one is cheap.
 I make a wrench for the tappet cover nuts, might make the job easier, or more enjoyable.

I didn't have a problem with the tappet cover nuts, it was just hard to get the feeler gauge into the hole and it was so bent, especially on the inner front ones, that I felt like the flex was hindering my ability to get a good feel for it.  I'm sure more experienced hands don't have so much trouble but this is my first time on this bike.

It's not that everyone has trouble with the nuts, but there is adequate...and better..

+1. I bought mine off amazon under $7. Size 24mm I think

IMO You don't need the cluthc holding tool for a CB750. Just put it in 5th gear and crank down on the rear brake adjuster.

The clutch spanner is a must. You don't need the carb tool but its handy for the extra long flat tip screwdriver. If your going to be rebuilding an engine you will need the tool to pull of the rotor. Clutch holding tool, never needed one.

I made a special screwdriver with a fatter tip that fits snugly in the wide slot of the adjusters, I always found that with the wide slot and a skinny screwdriver tip that you had to back the screwdriver off just to stop the adjuster tightening with the nut, this seems to make it a hit n miss affair requiring more than one go at it n I used to get quite pissed orf, not any more.

Economy gauges. Got mine long ago. the late '90s.
Mine serve the purpose, but I use them judiciously, as they won't tolerate
rough handling. Plastic restrictor/dampers, hoses that rot and split, and hose adaptors that need lock-tite applied to the threads (I super glued mine on) so they don't unscrew from the metal tubes. Works out ok tho, Syncs come out good. just use care when setting em up.

Nice the tool  I make is for the tappet access. Covers the 17 mm.
 I use a stubby craftsman. Screw driver on three tappet, while adjusting.

Thanks for all the help, my order is on the way.  Also, further research has indicated that the Carbtune is the ideal synchronizer, so I will be getting one of them.

Those feeler gauges are pretty much worthless and I had two or three of them snapped after only a few adjustments.
Just stick with the car gauges and bend them slightly at the ends.
