I just bought a brand new yz450 last week and just broke it in. So i changed the oil and oil filter and put all the drain bolts back in. After all the bolts were put back in i started it up and noticed oil was leaking from the drain bolt under the left foot peg. I figured if i tightened it alittle more since it wasnt very tight it would solve the problem. As i did that the bolt popped and when i took it out pieces of the thread were on the bolt. So i was wondering if i took it back to the dealer if it would be covered under warranty? cause im positive that the bolt was in straight and that i didnt tighten it above the torque specs. If its not covered how much of hassle am i gonna have to go through just to get it fixed.

I believe Yamaha has a 30 day warranty. In addition... always replace the washer and use a torque wrench.

did you lose the washer when you pulled the drain plug? I'd say that's the most likely thing. But still talk to your dealer, even if it was your fault since you just bought it they might be nice.

Sounds like they are still making Yamaha's out of old melted down lawn chairs.

i took it to the dealer today and the assholes said since i touched it its not under warranty and i have to pay for repairs, even though clearly i had nothing to do with it. The same thing probably would of happened if they touched it. I definitely will not be buying Yamaha in the future

I had an '05 yz250 and I noticed that the hardware the Yamaha uses seems to be sub par compared to other bikes I have had. I had to replace 2 triple clamp pinch bolts, 2 front axle pinch bolts and the oil drain bolt. All of them stretched and broke or stripped their heads and I was using a torque wrench on all of them. That sucks it happened to your new bike. Is there a way to can get to the threads to heli-coil them?

New bike, may have had some excess metallic particles , clutch plate debris and such that collected in the threads when you drained the oil. Could have caused damage to the threads when reinstalling the drain plug. Not sure how much meat is around that hole, drilling for a tinesert is quite an oversized hole. That may cause other problems. Helicoils suck. See if you can find a drain bolt slightly larger even if is not metric. Get a fine thread, not coarse. Drill and tap it to the next size up. Use heavy grease on the drill bit and tap to keep any shavings from entering the engine. Fill and flush before using.

i cleaned out the threads on both the bolts and the threads on the engine before reinstalling the bolts and it went in smooth when i hand tightened it. But if i have it tapped out is it gonna hold as if it were a new thread?

How are you "positive" that you did not over tighten the bolt, did you use a torque wrench?? On my YZ, that is a steel bolt going into an aluminum case. It would be very easy to over tighten it. Sorry man, no offense, but it sounds like you want them to pay for your mistake, though it would be cool if the shop only charged 1/2 rate or something. Yamaha's have a very good track record(lack of problems/recalls) compared to the other Big 3 by the way.

Yea i admit its possible it could of been my mistake but it never really felt like it was gettin tight besides isnt the copper washer supposed to do something to prevent that from happening? Anyways if they are gonna charge me $77 for helicoil thats ridiculous they could have at least tapped it out for that price im only gonna end up with the same problem in future

As far as the copper washer goes, copper is soft and helps create a seal between the bolt and case. It would not compensate for over tightening. On many race cars that I've dealt with over the years, helicoils can be stronger than the original threads and in your case that sounded like the best fix, IMO. I have never experienced a helicoil gone bad. Hope it works for you.

I only bought one Yamaha. Leaky things, and loose bolts were the reasons I never went back.

Personaly I would replace the helicoil with a Timesert . The timesert has a shoulder on it and the last 3 threads expand so it can't back out. The new threads the dealer cut for the helicoil should be the same pitch as what the timesert uses. In my opinion the timesert is superior to a helicoil and its stronger than your original threads. Lets go, Lets go, I'm Bored, Lets go.

It sounds like just a shady dealer. They definitely overcharged you. It shouldve been half that. Yamahas threads on some of the components are on the soft side. You dont want to tighten it down too much, but like Newmann said, some debris couldve collected. I had a similar thing happen on the sump tank on my old 08 YZ250F...except it was the vent bolt. I took it to my local shop and they drilled/tapped it and flushed it out for $30. Granted I am on a first-name basis with everyone there, however I am not sponsored or supported by them in any way.

what dealer did you buy it at? i know there are some pretty reliable dealers down there.
i would have talked to the shop manager or dealer owner and seen if they cant do anything for you, a reduced shop rate should have been offered. I will say though, if you "stole" the bike from them, i would say they might not be jumping at the opp. to give you a reduced rate if they did not make any money off the deal.
either way, dont let a silly drain bolt deter you from such a fine machine. i have owned several yamahas, and most recently, the drain bolt fell clear out of my 06 yz 250 and poured oil all over the bed of my new truck. shit happens. they are quite reliable though, and out of all the bikes i have owned, the blue ones required the least amount of mechanical maintenance. every bike has their ups and downs.

i got it at north american warhorse I paid $5200 for it which is pretty much how much they cost at the other dealers. The sales guy who sold it to me is a very nice guy however in the service department they are jerks. Yes i do love the yamaha but maybe what i meant to say is that i wont go to that dealer for any more repairs or just be more careful next time.

kawasaki drain bolts stretch too. I've started keeping spares for our kx250f's and I have had a couple kx 125's come through my shop recently with shifting problems that turned out to be the drain plug was stretched allowing it to stick through on the inside of the case enough to rub on the shift drum.

Those vent bolts are shit.
Ask the dealer for a bolt from a Honda crate if they do honda's too or another bolt and throw that bolt away as far as you can.
