Help replacing spark plug on XR250R

Okay, can you please check my procedure and tell me where I'm going wrong:

STEPS TO REPLACE SPARK PLUG ON 2003 XR250R

-----------------------------------------------

1 - Ask seller if he has the original stock spark plug wrench

2 - Thank him anyways

3 - See Motion Pro 18mm Spark Plug Socket in store and gasp at $25 price :smirk:

4 - Go to Lowes and purchase Kobalt 18mm deep socket for $6 :lol:

5 - Try new socket wrench and discover it's too fat to fit :p

6 - Go online and find OEM spark plug wrench, part# 89216-ML0-000 :ride:

7 - Order OEM spark plug wrench for $9 :)

8 - Receive email notification that the part is not available :lol:

9 - Find another online retailer and order the OEM part for $12 :lol:

10 - Discover it's not available there either because it's been discontinued :lol:

11 - Call Honda dealer who says they can definitely get it for me :)

12 - Receive phone call later saying they can't get the part for me :worthy:

13 - Go online to eBay and try to find stock spark plug wrench :p

14 - Get frustrated :p

15 - Give in and order Motion Pro 18mm Spark Plug Socket for $23

16 - Receive Motio Pro 18mm Spark Plug Socket #08-0175 for XR400 and other bikes :worthy:

17 - Discover that it doesn't fit for the same reason the Kobalt one didn't fit :p

18 - Remove two head bolts with 8mm wrench to make more room for socket

19 - Discover that there's still no way this socket will fit :cry:

20 - Run to computer to ask the experts here at Thumper Talk :cheers:

So......... what the heck's wrong?

I can't seem to find a stock OEM spark plug socket wrench anywhere. And the expensive Motion Pro tool doesn't even work. THe space between the cylinder head and the spark plug is just way to small, even for this thin walled socket.

I know an XR250R can easily run 20+ years on the same spark plug, but I've got this nice new NGK Iridium spark plug I really want to install.

Help!

if you can figure out what the outside diameter is that will slide in to get the plug take the socket to a friend with a lathe and turn it down to that od. and i run chapion plugs in mine 5/8" wrinch

see em on ebay all the time. I bought a new one from Service Honda or XR's ONly less than a year ago.

I says it will fit, but it doesn't.

I've been searching eBay for 3 months and can't find one. I'm using the stock part number as well as "XR250R tool" "XR250 spark plug" etc, and comeing up with nothing.

that one pictured will work 100%

I lost the stock spark plug wrench for every XR I've ever owned. Just grind that deep socket down and it WILL work.

There's a trick to getting the socket in place. If you just tip the socket into the hole from the front of the bike, it will hang up on the nubbins sticking in from the side. You have to go high and towards the rear, and drop the socket down from the top. If you look closely, you'll see where it just scrapes by the nubbins when you do it right. :ride::)

PS any thin-wall 18 mm socket will work, but it has to be thin. :lol:

did the exact same thing with the kobolt 18mm, got pissed went to honda and paid $25 and they ordered me the honda wrench. Mine was for an 94' xr250l should work for yours though. Dont know why honda says they cant get yours mine came in 3 days after I ordered it.

The dealer said it was discontinued and that the Motion Pro would defintely fit. I asked them if there was another, newer Honda that used a 18mm sparkplug so I could order the OEM socket from it, but they said no, just get the Motion Pro one. I suspect they didn't have the energy look through their online catalogs to find another one that woulf fit :lol:

THANKS GUYS! :ride: I bid and won :) that one on eBay.... and paid for quick shipping, so hopefully it will be here in a few days!

BIG THANKS TO EVERYONE who responded. I greatly appreciate it! :):lol:

I just use a box spanner and bar on my 250, not a problem.

You suspect right. The 400ex is still out there and has the same tool/issue. Cost is $8.13 and uses anything like a screw driver or allen wrench to turn it. They're wrong about yours being discontinued too, the XR250 socket is $8.96. Little advice, I gave up on parts counters LONG ago. You'll over pay and most of the time talk to fools.

markgoodall; your welcome

A box spanner? Box spanner? What do you think this is?? England? :)

:lol:

Ah yes, I recall me mum calling it that when I was but a wee lad. :)

Actually the stock/OEM spark plug wrench is a "box spanner" except here we call it an "impossible to find light-weight spark plug wrench".

Hardware and automotive stores sell them but usually only in a 5/8" size, often as a lawn mower spark plug wrench,

but other than that most any other place that sells a spark plug socket wrench around here will be like this:

Box spanner? I haven't heard that in years. Think I'll call me mum tomorrow and see how she's doing. :ride:

Nope :thumbsup:

You're NOT gonna believe this...... I actually bought two from this guy on eBay, and received them....... they don't fit. :eek: :eek: :eek::banana: :banana: :banana: :banana: :banana::D:banghead:

Okay....... think I've figured it out. It's pretty crazy. Need to check a few things for accuracy before posting the answer.

Stay tuned!

Ordering the OEM one isn't crazy, why haven't you gone that route yet?

You probably figured out what ramz told you in the beginning of the thread. If the socket is not aligned exactly right it will not go in. Once you figure out the angle it needs to go in and how to do it it will work like magic. I use a regular Snap-on deep socket. The diameter of the socket did not need to be turned down on a lathe either.

Ordering the OEM one was already attempted in steps #7, #9 and #11

Thanks anyways.

Nope, that's not the right answer either. But thanks anyways!
