You Gotta Be Kidding Me!

29 posts in this topic

Forgive my ranting.

Got the new '04 WR450 a few weeks ago. Picked it up on Saturday, rode it for the first time Sunday morning. Came back with a right boot covered in oil. (And a heck of a cloud every time I stopped.) Well, I didn't know about all the great information here at TT at the time, so I took it back to the local Yammy dealer. While they had the bike I discovered TT and searched and found all the posts about the decomp plugs and what pieces of crap they are. So I ordered a plug from the TT store. The dealer had the bike for a week, which wasn't a big deal because the TT plug wasn't here yet anyway. Went riding this afternoon, the first real ride since getting the bike back. And guess what, so much for the new plug. (I stupidly thought since the new plug was on there I'd wait for it to come loose before replacing it with the TT plug. Yea, I know - I'm a moron.) But all this isn't what has me ranting. The first time the plug came out I never saw it. This time it was kinda half hanging in the hole. WHAT A COMPLETE JOKE THIS THING IS. I know they come out, but I was certainly expecting to see something a little more robust that what I have in my hand. (Which is nothing more than a plastic cap atop about a 3mm sleeve.) Somebody please tell me there's more to this thing I just haven't dug out yet, because it's hard to believe that any manufacturer would consider this as a working solution.

Rant over. :ride:

Nope what you currently hold is some suits idea of a great fix. :p:ride::banana: .

So far I have only lost mine once ($1.96 part) but what a pain in the :ride: to clean that oil off the back of the rad and the boot.

My TT decomp plug will be on the way soon :ride:

Nope. No plug after '04.

If you go to an engine rebuilder you could get an 18mm steel or brass oil galley plug for next to nothing and it will seal off the hole as well as the overpriced TT plug.

i have only lost my plug once and never had anyproblems again! And the funny thing is after i repaced the "lost plug", when i was cleaning my bike from all the oil there was on it, my old plug was right on top of my skidplate lol :ride::ride::banana::ride:

someone said "overpriced"...but the TT plug is a well machined piece, and work VERY well. I had the stock plug ruin a perfectly good Dune ride a year ago.

and yes, it is insane that yamaha considered that plastic thing to be a viable solution.

So, what you are saying is...

One day, my 2004 WR450 will just decide to eject this plug, even though it has over 1000 miles on it? :ride:

Of course I didn't even get ten miles out of either of mine. :ride: But I'd go ahead and replace it anyway. It's cheap insurance. When (or even if) it does come off you have a direct passageway into the engine. As long as the bikes running of course the pressure is outward (you can see the oily mist spewing out of the hole when you rev the bike) so probably nothing is getting in. But if I'm out splashing through the mud when it decides to take a hike, or if I haven't noticed it's gone yet and I stall it in some nasty stuff.....

Searching this subject turns up guys who had their bikes longer then you before theirs came off.

And I agree with ARin - you could probably jury rig something but why would you? This is a quality part not to mention that supporting the TT store helps to keep this site here.

:thumbsup:

Nothing jury rigged about my method. It's been a time tested method of plugging oil passages in engines for years. I just can't justify spending $22 on a glorified metal plug when I can get something that works equally as well for less than a buck. Maybe I just don't care about the "BLING" factor.

Again :thumbsup:

What does the original plug look like WHEN ITS INSTALLED? Does it have a metal endcap? or is it completely rubber?

From the outside all you see looks like black plastic that's flush with the hole. Once off you see there is actually a metal backing to the flat circular surface. That sits on top of a little less than 3mm sleeve.

From the outside, i see a metallic plug. It's shiny, kinda like a cadmium plated part. I dont think it's original, and i'm wondering if my engine already has something installed in place of the original plug (i didnt buy the bike new).

Should i take a picture? or can someone tell me what plug i might have?

OOPS !!! i just cleaned and checked that plug more thoroughly. It's a black rubber plug :thumbsup: . I guess i can either make a aluminum stop for it, or get a TT plug.
