so im from sd and this past spring i sold my 05 mastiff and picked up a brand new 08 mastiff that dealer never sold.. bike has around 1200 miles on it now.. i was riding and noticed the clutch started slipping on me through gears at highher rpms.. on my home and hurd kinda a clunk i the primary..well got about half mile from home at stop lightand went to take off and it jerked once went a lil jerked again and it killed the motor.. motor was runnig perfectly fine..positive nothing wrong there.. but now when i go to start it up it just spins like the starter isnt catching.. guessing primary chain is broke or i sheered some bolts or something.. as i said this bike was like brand new so maybe they didnt loctite some stuff.. any input or concerns.. is there a better clutch to upgrade with as well.. spring is coming and looking to tear into as soon i get some free time..

1. Toss it in top gear. Push the bike. If it freewheels = Primary chain.

2. If it bumps and can turn the crank = Not the primary.

3. If it spins the starter = Starter one way clutch gear may freewheel, not turn the clutch outer or where the big ring gear is placed in or out.

4. Noises: Not certain on this, but if the ring gear is inboard close to the trans, meaning, could the the starter shaft bolt come loose, pop out the case, down the primary, on top of the bottom chain rung, locks the outer clutch housing's primary gear teeth to chain rung?

First thing to do is drain the oil out of your Primary. Then remove outer cover. You might find that the clutch assy is loose. Remove the throwout bearing from the center of the clutch and inspect the nut. It's possible the entire clutch assy is hitting against the outer primary cover.
Another possibility is the starter output shaft sheared off and jammed up between the chain and clutch side or drive sprocket side of motor.

You don't drain your blood or have a transfusion because you broke your finger. Either you can throw the pinkie backwards, has a crack, or is just bruised sort of drain the plug.

Then remove outer cover.
I see where you're going. But this is 'WATTs behind door #2?.' It's like saying, lets tear down the engine, not leak it down to see who is at fault first. See where I'm shooting from the hip?

You might find that the clutch assy is loose.
Another good call with the others. However, don't you think it would still crank over with the main ring gear to starter gear? How loose are we talking before he heard something?

Remove the throwout bearing from the center of the clutch and inspect the nut.
No. Keep the whole clutch assembly together. Grasp behind the ring gear or clutch outer, then push/pull back and forth on the shaft to see if there is a loose nut? Home he moves the X to Y there is a noise first?

It's possible the entire clutch assy is hitting against the outer primary cover.
Again, good walk, but this is something tied up? Free spinning? And if something is going to tear up the primary cover, it would not take this long to walk that far out. Why? Because you pull the clutch lever, you be pushing the whole clutch is the basket, right?


Another possibility is the starter output shaft sheared off and jammed up between the chain and clutch side or drive sprocket side of motor.
I believe the OP has stated the shaft seems to turn, but is clanging or not moving something at all? So if it was the clutch as you seem to be pointing to, how is it the engine is not moving yet is that walk in top gear before you oil the floor with a clutch chase is it?

You be narrowing down that puppy better, no? We start in wit 3 pages of going knowhere but to the problem, yes? :2thumbs: Sheer is she wear out your abstract is you be playing wit day big boys is I gotta read some clutch basket bolt loose is a goose chase is it?

SVEN, your an idiot. How many Big dogs or any American made bike have you actually worked on? None from what it seems.
Loudmastiff, send me a PM and I'll give you my number so you can call me and talk like normal human beings. Not this mumbo jumbo BS that SVEN keeps contaminating this forum with. I'm sorry but sometimes your posts just piss me the fuck off!!! :angry: To have you on here posting this shit is like me going onto a forum for Apache helicopters and thinking I know what the hell I'm talking about, when in reality I have no clue.

You're a dolt, not 'your' an idiot. :job:

Not a one. You are correct, sir.

... and talk like normal human beings. Not this mumbo jumbo BS that SVEN keeps contaminating this forum with.
Most of my stuff is so blatant generic I wouldn't enter any post I have no clue of not knowing a little something about it. Drive-train? I think I can handle a car's rear end, trans, transfer case kind of piece of cake is a clutch basket and a chain hooked up to a crankshaft. Lots less parts, don't you think?

I'm sorry but sometimes your posts just piss me the fuck off!!! :angry:
Fucking piss is me to no end how simple this bike shit is. The fuck you getting on my case when the both of us have not a fucking clue what's wrong with the bike there, guy???? Simmer down! :flag:

To have you on here posting this shit is like me going onto a forum for Apache helicopters and thinking I know what the hell I'm talking about, when in reality I have no clue.
I'm a quick learn, fella. This bike is a copy of a harley engine and transmission. It sure is not a complicated helichopper that's for sure.

I'd sit on the bike, rock the bike from side to side to see if your clutch basket screw was loose? :whoop: Like I said, I can hold my own, guy. Just relax and deal with the public like I have to. It's only a fucking bike. :roll: I don't know what the fuck you think you have there, jr.

Here, so it looks like you know something: The engine only assembles one way. Fuel-spark-compression are so the fucking absolute, it makes both your choppers roll and fly. I think I have a clue about engines, bikes in general?

Now, grab your trousers pull them up like I do and put up with the runner upper types I categorize you get on my case for one second and not help the OP. I'm very careful how I choose my tech threads.

Hey, I didn't say rust. I said carbon so clean is the part, you open the oem box it came in... YOU see new rust is it? FUNNY!!! Is that the fluckle duckle did I say? Confuse your ass is so it so in your face you don't see it!

:iamwithstupid: I wit steam clean

Signed,

Steam off the carbon. I said, 'don't worry about rust.' Why? The chamber lives in a gas and oil type environment, not lives under a shower of water, meaning thinking any rain is going to ruin an engine... It gets a little water in the engine and you keep riding it till the sun comes out. :roll: (JK)

Listen to Bigdogtech01
Look, all I did was walk Big's tech walk. The diagnostics have to walk. Yes, there are tons of guesses. But you sort of hear funny noises described by the OP, or more, follow what the OP describes.

You now walk the OP's abstract against the next poster's [Big's] abstract. You walk my abstract, it's going to sting you as in, we both walked the noise, but Big forgot the clutch lever pull. That's the walk-thru. That puts you in the [penalty box], about someone needing to sit down and let the less experienced with not a clue about a noise problem, is to cancel one post after the other. That is my walk cleaning up your walk.

If you do not walk what the OP explained as best he/she could, go off in a different direction. Get it, Big? You went after X [the clutch pull] and I went after Y [the chain broke or a part is caught] factor.

Like a chess game move. Like coming up on you at a turn showing you a wheel [how slow you be going] around it. Z da shit for all it squirts?

Yup, like I said...IDIOT!!! :loony::loony::loony: I can't have a conversation with someone like yourself who thinks he knows everything, when in fact your lack of intelligence is an embarrassment to the forum. :bang:

first off im 9 hours away from my bike at the time.. im pretty mechanically inclined.. i work 95 hours a week in the oil field in nd.. just dont have the time as of right now to tear into it or i would.. and its 10 below zero here for another couple months so i do have a lil time.. but anyhow the clutch did start slipping pretty bad..and felt something and heard it in primary.. bike shifts through all 6 gears just fine.. and while in gear if i want to move it i have to pull in the clutch.. bike rolls fine in neutral.. it just wont catch to turn te crank when i go to start it.. im thinking bolts broke or something.. wish it had some kinda warantee.. rode it one summer.. and i used to own the fabulous 05 nightmare.. had the whole motor problem with that.. dumped a fortune in the thing.. but love these bikes and want it fixed.

Sven...im with these guys speak english or get the fuck out

That's what kills me... all these jackoffs bitch about how you post. "If English is your second language, go back to school."

After 20 minutes of quieting my mind and re-walking the talk/theory... piece of cake. I could follow your theory anywhere!

If we get that... fueling, ignition, Kskid, secondary throttle valve modulation... its all there. Ripe for the picking... for those that can walk the theory.

Guys, guys! You start tagging names to me being a knowitall, and that is a tall odor. I leave that to those runner upper guys that use 'tech' in their names. So they are the ones that know it all, being they be telling me I'm an idiot on top of it.

And this is no offense to anyone, but I select the world's fastest production bike and lighten it even more so it's that much quicker. I'm a chopper kind of guy, no? And that quote above was from someone at a different site sending me a pm.

I treat each website the same absolute way, because there is no other way the bike plays out. And thank you, loud. You proved where the tech direction was going [by your INITIAL description] that sounded more of the direction I was thinking.

Others chimed in to tell you to follow the wrong direction. Now, do you understand how many directions are the probabilities? If it is not X, then it's Y. In this case, your bike did not hit the cover as the tech was describing cover damage and a loose clutch housing was about to walk in the Y do you think I sign off as NOLTT?

Because! :roll:

Loudmastiff, as Andrew said, removing the outer primary is a very simple procedure. Yes it will cost you a quart of oil but it will allow you a full view of what is going on inside the primary and quickly allow you to see if the clutch nut is loose and causing the problem or if there is a problem with the starter.
If the clutch nut is loose and allowed the clutch pack to slide outwards on the transmission shaft, it would be the cause of all the things you describe. This isn't brain surgery and you will only have to buy a quart of oil to know what is the problem.
If it turns out to be your starter, give Curtis(Wild Steed) a shout and he can fix you up.
If it turns out to be the nut on your clutch, get some red locktite and re torque it.
If damage has been done, we have plenty of help on this forum to get you through it.

I would pull off the primary cover to check for any broken parts, make sure the nut on the clutch and engine side are tight, no play in the input shaft, and that the clutch carrier is not broken.
Feel free to contact me for any help as well.

Clutch hub nut as Andrew said. My 2008 Mastiff had the same issue, also two nuts on the back of my clutch carrier came loose and made a grove in my primary back plate. While you're in there you should pull the clutch assy and make sure the thin brown seal has been removed from the trans main shaft. There was a service bulletin that BD sent out on that. My scoot still had the seal on and I removed it.

Fighting To Help

Raywood, I to wish thank each and every member with such passioinate desire to help a fellow member with his/her bike. IMHO this is what makes The Big Dog Biker Forum such a great site! Think about it; these guys were ready to go at each other if they had only been in the same locality. The only issue I saw was a little communication gap. On the other hand, thanks for monitoring and applying the brakes before things went too far.
