I want to kick the Japanese engineers in their egg rolls

I tried removing the throttle stop screw from my Wr450 last night. Why in the hell did they use a safety torx screw when they know it's going to be removed, in fact they sell the replacement kit with the new screw. I so far can't find a T27 torx safety bit after 4 different stops. All I could find was a multi tool contraption with one on it. Then the location of the screw is idiotic. I had to take the whole pipe off just to get to it and then the tool wouldn't fit. The only safety torx bits I could find were 30 and up. Every time I work on a motorcycle I think the Japanese engineers are trying to get back at us for WW2. It's working. Rant over.

Or maybe I'm just an idiot who can't even post my whining in the right forum area.

Sears Craftsman makes a bit driver kit with tons of security tips. Torx range starts out pretty small. I've used it a ton of times for many things. I think it was like $20 or so a few years ago.

Flash: it was the US Gov't that required both the stop screw, the tamper-resistant torx that anchors it, and the bore plug that hides the pilot screw.

Not the engineers.

Varieties of egg rolls are found in mainland China, many Chinese-speaking regions of Asia, and Chinese immigrant communities around the world. Not Japan.

OP: Use a metal hacksaw blade. All you have to do is slice a notch in the bolt (and it's easy to reach with the blade). Once you have a notch you can then use a rachet with a 1/4" socket and put a flat head bit in it. Simple and takes less than 2 minutes. There is very little torque on this bolt so it will break loose easily. This is how I got mine off since I wasn't going to buy a safety torx bit for a one-time use.

thank California's green sticker politics

It is not a US only thing. Same set up here , we have a "learner approved" licence class here in NZ and power to weight is the governing factor. Thus the restricted state of approved machines. Easily rectified however :-)

An awesome bike once opened up and worth the hastle !

Yeah, well, trust me. If it's ridiculous, it started in California.

Yeah, I was a bit frustrated at the time and was venting. My appologies to anyone of Asian desent or anyone fond of eggrolls I may have offended. I did however, figure out my problem, well pertaining to this situation. The rest of my problems will take years of therapy to sort out.

In doing my research everything I found indicated that it was a T27 safety screw head and given the angle and location made it very difficult to figure out why I couldn't get the bit to bite. It turns out it is actually a T25 safety head screw and once I tried that it came right out with little fuss. I found three different threads online; one here on Thumpertalk, one on Supermotojunkies, and one on a U.K. board that all indicated a T27 and since everything on the internet is always 100% accurate I never questioned it. I don't know if Yamaha has changed the screw they used or what, but for anyone in the future who is doing an internet search for this information, make note that mine was in fact a T25 safety torx head screw.

FYI you can find a Klein safety screwdriver at home depot for$25ish with those irritating bits in a kit. Also buy a 1/4 ratcheting wrench and the bits will sqeeze into tight spots.

Thank god it's a Yamaha. You don't have to do them very often. Getting the valve cover off is a giant suck.

I'm not gonna do valve checks. I'm just gonna run it till it grenades and then report it stolen.

Gee, thanks for being part of the problem

I thought that was a ridiculous enough of a statement that the joking would just be implied. However, I forget this world is full of idiots and there are actually people out there who would do just that. To clarify that is not my intentions.

Those wheels look horrible. I think you should remove them and send them to me for proper disposal!! :lol:

Just for disposal reference, is that the stock front rotor? :thinking:

Hacksaw blade brilliant! I've been cussing for the past 2 hours and now 2 minutes done! Thank you! Man that was a pain in the ass.

My torx bits are from harbor freight.  I think they were 3 bucks.
