Topic: Valve adjustment tool

[fredmalito4]

 What are you guys using to adjust the valves on your engines without removing the valve cover? That’s not going to be a big deal on my chopper as I have plenty of frame space, but I can’t seem to get my normal or angled feeler gauges in to the hole created by the tappet covers. Recommend me a special tool that I could go out and buy so I will quit cussing! Thanks everyone.

This is what I use for adjustment, it's just the lever from a 1/4 turn valve with a slit  filed in to it .

I just ordered yesterday https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F251646351273

Seller has also another tools available, I opted for full set. Hope good choice.

I’m sorry that I wasn’t clear, it’s the feeler gauge that is the problem. I can get a wrench and screwdriver in without issue, though the tools that you guys showed are pretty groovy.

I find it easiest to back the screw off a few turns, slide the feeler in the gap then set the gap. Once I get the amount of drag I like on the feeler, I tighten the nut, check drag again, and remove the feeler. I agree that its difficult to get even the bent feeler in between there on some of the valves.

 On 750's I just have a simple long feeler blade gauge with the tip section bent up a little. I like to have a .004 also to see if the exhaust are too large. I have never had any problems setting tappets with these blades, a 10mm wrench and screwdriver.

The Motion Pro bent feeler gauges work fine for me on all the SOHC-4s. And Honda made a tool for the square adjuster head.

Like he said, not a big problem on a 750. Easier if the feeler guages are loose  like not  with all the others.

 Thanks, guys. I found the Motion Pro bent gauges and I will order them up from eBay.

The Motion Pro gauges made a huge difference for me.

Fred which bike are you working on .?
 Are the ends of your adjusters square ?

[fredmalito4]

‘78 750K, mine are flathead.

I’ll be working on a ‘71 next week. Are they different?

4 into 1 has small two ended single metal feeler gauges with bent feelers that are decent quality and dirt cheap. I have worn a few out yet at the price I usually buy a couple of the two different styles at a time. I believe on the one gauge the feelers are .002 the other end.003 on the second gauge the one end is .004 and .005 on the other end.

DSS has the small OEM Honda plastic topped tool for the square valve adjuster. It is really cheap in the US for about $8 US. When DSS were OS recently I tried to buy it up here in Canada from Honda and they wanted $65 for the same tool?`

I just buy them from local auto parts then pull out the sizes I need and attach to key chain ring, then hang on my peg board, also have offset 10mm closed wrench and thin screwdriver with big fat handle, icalso seem to use my headband flashlight almost exclusively when doing valves,

I use the MotionPro    .002-.003 also . I've found after some use the metal will kink up a bit . I now try not to push the gauge straight into the gap as to do a side swipe stroke to check the clearance .  Another .004 gauge is also helpful as a previous poster stated to check the exhaust is not too loose.  I just last week put a red dot on the exhaust side and a yellow dot on the intake side of the MP gauge so i don't have to keep looking @ those small stamped #'s.

That tool is very handy. I bought one a year ago. That seller has the CB750 Shop manual in new print, nice to have when sitting in the sofa planning how to do, not in the garage making it dirty.
The other tools such as clutch and wheel hub retainer tools are needed too.

I hold the  with three fingers in a U shape,  and try to force them in wiggling as I go.
 A 3 or 4 thou shim likely won't lift the valve.. if it gets in its good.
 Also I check with next size sometimes as a no-go check.

get a feeler set you can remove the blades from not a riveted set,scissors will cut the rounded tip off the ones you need,this will leave a burr so use a knife stone to smooth it away both sides,use them off the main stack,bend em as needed.
