Blew the motor up today :(

[Dogmeat]

35 miles up in the hills, thing decides to squeak a piston on a light spring snow day ...

It was running AWSOME until then too, then it started bogging ... I thought at first I might have some snow in my new snorkel air intake ... wasn't the case ... It started back up then died, sized up cold.

Towed it 35 miles back with the M8 ... got it in the garage, dumped some oil in the cylinders .... it turns over now, but it's real hard.

I think I'm at the "enough" point right now. This motor had barley 200 miles on a brand new top end that Carl's Cycle did for me last spring ..... *sigh*

wtf ....

That makes two of us!

Lost mine yesterday. A tough knock for me but, you've taken an absolute beating- feel for ya man. Makes me hesitant to fix mine. Wish I coulda met you when you were in Crested Butte this winter. That was probably the biggest shot of snow for us this year. Rode a nice M8 this winter. Liked the power but the ride just didn't excite me much. Something that runs should be exciting enough, I guess. Good luck Dog, You've been fun to follow on the forum. If I ran this kennel, I'd defintely throw you a bone!

I think I might snow check an M10 for next year ... :hs:

I dunno, I'm gonna get the garage cleaned out and get all the summer toy stuff outta the tubs then put this thing in the back of the garage and just start tearing it down ...

I really wanna get the motor out of it sometime this week and try to figure out WTF happened, it kind of has me worried.

It just sucks so bad because when this thing runs it runs like a striped *** ape ....

Funny (not really ) how they always run best right before the sheet hits the fan.
Is it possible Carl's will help???
Sorry to see it down!!

 

[Dogmeat]

If anyone wants this sled as-is plus every spare part I have for it, $3000 will take it.

 

[SLDHVN]

what really sucks is the fact you can barely get 3000 for it in running condition. i know personally...

send it to indy dan, let him work his magic.

then ride it for the rest of your life... i think thats what im gonna have to do with both of mine, good news for me tho, they were both already in the indy shop.


whatever ya do, good luck!

ski

imho, buy a 2010 like i did and HAVE FUN!

Does he do top-end stuff too or just bottom end stuff?

I've already got his TMIII bottom end ....

 

[SLDHVN]

he does it all, well worth it too, i have 3 of his motors now if that helps

 

[Dogmeat]

I'll give him a call and see what he thinks it'd cost me to just ship him the whole damned thing and have him go through it .... I'm HIGHLY reluctant to spend another dime on this damned thing right now

 

[Dogmeat]

Welp, started tearing the sled apart this evening.

So far I've got everything off the motor, all I have to do is drain the oil reservoir and coolent and yank the motor ...

Inspecting everything thus far, I have some kind of brown **** caked up in the exhaust ports ... I dont know what this is. It's on both cylinders though.

The oil lines leading to the crank case are both primed and full of oil, so it doesn't appear to be anything wrong with the pump. The oil pump cable was aligned properly, etc ...

I'll post some pictures of everything when I get the jugs pulled on Sunday ....

I am DEFINATLEY giving this sled a thorough cleaning. I had thought I cleaned it up pretty well at the start of the season but it's dirty as hell again after only two rides

 

[f15ejedi]

If its really dirty after two rides you might be blowing oil someplace then everything is sticking to it causing it to get dirty. Is the brown stuff in the exhaust like soot?

 

[sled_guy]

Dogmeat,

I composed a big post about your luck and what not... but then deleted it. My only advise, which I think was the advise the last time, was to not spend another penny on the thing.

Not really, it's sort of sticky even ...

That's kind of where I'm at ..

Like I said, if somone came along and offered me $3000 for it as is they'd take it.

heh

As it stands now I'm probably gonna have to get it running again just to have any hope of selling it.

Not to hijack the thread, but just throwing this out there... If anyone is looking for a motor, I just rebuilt my 06 motor from the ground up. 2400 total miles on the engine, had new pistons at 900 miles. About 50 miles ago it went down on me, so I did the 32mm crank kit, new pistons, new reeds, new everything except cases and cylinders(were perfect when I pulled them off). I am wanting to plant a boosted 4 stroke in the chassis. I don't know what it's worth to somebody, but the SLP pipe, can, head, ecu, wiring, this and that could all go with the motor. Again, just throwing it out there to see if I can't help a fellow 900'r out!

Friend of mine tore into the bottom end of the motor.

The motor had maybe 300 miles on the new top-end. It was using oil when it croaked, or at least it appeared to be. It was running flawlessly right up until it seized.

Here's pics:

Suffice to say, I'm done with this sled. I'm gonna email Indy Dan to see what he would charge to just do the whole motor for me (mag side cylinder needs replated too) but I am willing to bet he'd want several thousand dollars and Im not about to spend that on it.

I'm gonna go pick the sled up sometime in the next couple weeks and strip it down to the bulkhead and part it out and sell it, so if there is something anyone wants off of it let me know. I'm done with it.

 

[mountainhorse]

DM...Sorry to hear about your chitty luck.

That looks like an Indy Specialties FULL billet crank.

Wondering what gave up??

Did you loose a piston and scatter debris in the bottom end?

Do you have a pic of the Mag Side Crank throws/rod?

I'm sure that Indy Dan (Indy Specialties) will work with you on a solution to the problem.

Good luck Bruddah!!

 

[indydan]

??????????????

Yeah Aaron, where are the piston picture ???

all the pictures you have of the bottom-end you have showen don't show anything wrong other then a Mag rod drag mark on the case ??? did the rod bearing fail ?? or was piston material just dragged under the rod ??

Dan

 

[indydan]

PTO end bearings

Aaron, I think you got the first TM 3 Full Billet I sold & if you deside to rebuild the top-end again you should send me the bottom-end and I will update it to the triple PTO bearing and no-charge to you and I check the rest over to make sure there is no metal in the bearing from that Mag piston.

Dan, here are the pics I took of the motor right after I pulled it out of the sled. The motor is at a friend's house in Colorado right now. I will have to see if he can take more pics of anything specific you would like to see.

But, the connecting rod bearing did fail. You can waggle th rod back and forth about 1/8" or so. PTO end appears to be just fine.

At first what I thought caused this was a reed failure, the intake manifold on the MAG side was dirty as hell, the PTO side was totally clean when I took the cylinders off the motor. Upon inspecting the reeds, they were just fine. We're kind of trying to figure out where that black plastic junk came from, it might have been the crank seal ...?
