JIS Screwdriver for 400/4 Carb slide screws -Trying to source correct fit please

<< < (2/3) > >>

ST1100:
I too vote for Vessel screwdrivers...
I also got me a 1/2" Vessel bit-set for the air rattler, as well a small 1/4" Vessel bit-kit for the tiny BOSCH GDR 12V-110 cordless impact wrench, way gentler then the impact thing you've to beat with a hammer...

MrDavo:
I have an excellent pair of stubby blue JIS scewdrivers, a fine point and a more blunt one, as well as a long shafted driver. I got them via eBay. The downside was they were packed in a stupidly big box, that took weeks to arrive from Japan. I've never had much luck with toolkit drivers, maybe they are worn out by the time I get them.

That said, the one screw they couldn't get out was one of the tiny screws in one of my Z1 carbs, which I needed to shift to move the needle, so exactly the same screws, albeit Mikuni not Kehin. The one that was well and truly stuck started to chew the head up rather than budging, so I took it to my bike engineer mate, who used a pillar drill to get it out. He didn't want to use heat as he was nervous about distorting a slide that is a very close fit.

Thanks Ash and others for your replies, most helpful. :)

Ash

I selected the Amazon link which took me to a choice of 4.

1. The opening item describes the set as:Vessel Megadora 900 +1x75 +2x100 +2x150 Cross Point Driver Set of Three Items Original Silicone Cap .  It doesn't specify JIS on these. 

2. There is a JIS item listed below a: Vessel Megadora 980 Impacta P2x100 P3x150 JIS Cross Point Screwdriver Set of two items Original silicone cap .

Could I confirm please if it was the item 2 that you recommended or is it a different model.?

For the carb slide job I would prefer a solid normal twist non cam action. rather than an impact, due to the frailty of the surrounding components.

The shanks on these look slimline enough to get through the tight space to reach the screw heads.

Thanks :)

Dennis
