Well I mange to mess the bike up again. Before a clanking noise was sounding @ the beginning of each start up. Then it started fading away since i changed the peacock back to on it was on prime. I just changed the oil ran her a lil then let her sit so i could check the oil level now it wont start


This sucks ima just go buy a BMW now

Don't have any idea, but it sounds like the engine is not cranking up.

[UnshavenCanuck]

Sounds like the starter is spinning but not engaging, looks like you need a new starter solenoid or atleast have a look at it. I haven't had the starter out of my pregen but on a car it has a lever that engages the starer drive, could be broke, might explain the rattle. Good luck

agree. sounds like the starter is not engaging. pull the starter or the engine cover to check.

[cuong-nutz]

ditto on starter not engaging.

[ricomtzjr]

+1 on starter not engaging

How could this have happened?

[UnshavenCanuck]

Don't know if it's possible to do but could you have hit the starter driving down the road? Possibly meaning to honk at some douche that cut you off because they didn't see you...lol. Again I'm not sure if there are safeties in place to prevent this, I don't feel like testing if mine does, but if there are maybe yours is broke.

[UnshavenCanuck]

Did you find all the pieces? Its probably safe to assume the starter is okay, just make sure the gear sticking out of the starter doesn't have a ton of side to side play.

The teeth of that gear are fragile and can break if something gets in the way of them while meshing the starter idle gear or if the shaft (13107 part) of that one breaks and the gear (59051 part) gets out of position and jams the big gear (16085 part) while rotating.

Hitting the starter button during riding should not cause that damage, since there is a clutch between the big gear (it only rotates one way) and the crankshaft.

Are the teeth of the starter idle gear also damaged?

^^^ What motofool said. If you need to order parts, let me know! I need to order more crap and would like to save on shipping.

[mgentz]

you will also need the proper tools to remove and reinstall the flywheel....don't forget!

[cuz]

Thanks Motofool

No its just the flywheel all other gears are perfect. It seams that the little gear that connects to the starter and the flywheel did move around.













Only found 2 teeth still looking for the others."/
Really thinking about boring this engine.

[Racer x]

. This is very strange.

The starter on a motorcycle is really different than a car. The motorcycle starter is just an electric motor. No solenoid and no Bendix drive. The Bendix is the thing that engages the fly wheel and let's go when the engine starts.

Motorcycles have a one way sprag and gear on the crankshaft. The starter is driving an intermediate gear and the solenoid is mounted near the battery.

Breaking. Teeth is very strange. All the gears all always lined up. There is no in and out of the starter gear. It is always in mesh with the starter wheel. To break four teeth you had to lock up the motor or something got in the teeth.

[tubarney]

my little gear looks exactly the same but my teeth and starter are fine.

I'm pretty sure those grooves in that little gear are meant to be there. But that doesn't make sense because they aren't even

Please correct if I'm wrong.

[Racer x]

The back side of the intermediate gear has a weld around the shaft hole. That looks normal. Are the teeth OK on the other side?

The teeth on the other side look good. I didn't have any problems before so its good to know those marks are normal. I was a bit worried.

[drphils87]

Wow how could this happen? Did you all decide that it was a foreign object in the cranckcase that this? Or were we just lucky enough to get a messed up gears? My bike has almost 7k on it and it just did this.

Off topic but i notice you have WC rearsets, do you just have your shifter set high to avoid hitting the sidestand? I road like that for 2 days before i could not take it anymore then i took 1mm off the bottom of the shift lever with a file until it cleared the sidestand in the next lower position, soo much better

[drphils87]

Lack of quality in that one part? How many miles do each of you have on your bike? Notice all of ours are almost the same year. Mine has almost 7k.

Can I use a standard flywheel puller or does it have to be a special tool?

Is the big gear the only thing I need to replace?

I just changed my oil two weeks ago, I put it all in a big piece of tubaware to safe it. LOL

Is it a centrifugal clutch like a gocart?

There is a special tool for that, but I don't know the code for your bike.

[mgentz]

the unit is kind of like a centrifugal clutch. In one direction it is bound to the flywheel with three weights. In the other direction it spins freely. My guess of how this happened is because of the back fire or something that causes the gear to bind and then the starter broke the teeth. I guess that's because the same thing happened on my bike and I know it was because of a backfire.

[drphils87]

@mgentz so what your saying is the first time my bike fired on a cylinder it backfired causing one tooth to break because it turned the wrong way, but only for a breif moment, and then while I turned the bike off and started it again, it only had one tooth to grab, breaking that one tooth with the next start until it had no more teeth to grab?

I cannot move (haven't tried excessive force) the big gear with the broken teeth in either direction. Is this good or bad?

@Motofool I REALLY don't want to spend sixty bucks on a tool I'm only going to use once, so unless someone will let me borrow his or hers for a decent price plus shipping, I'm just going to see what I can do with what I have. Is it tapered on there?

This is off-topic, but how do I get this blasted overtype to stop?!

[drphils87]

So that's at least four people with the same problem.

[mgentz]

Don't get a three prong puller get the mp tool that I'd basically a nut and a bolt for $30

Yes. As I said any counter force on the gear while the starter I'd trying to overcome the motor will shatter the teeth. Based on the perceived metallurgy of that bronze gear it would be quite easy to dnap off a few teeth. Once they go the idler gear gets overstressed when it gets to that gap.

Another thing to check for I'd smooth movement in that gear behind the flywheel. Mine was binding so bad that I'd blued the gear and turned it into a pretzel. Then snapped the teeth.

I changed it for GP shift.

Exactly 8726 miles.

Yea its just the big one. Unless other stuff is broken too

[Dano]

I got a 09' hope this doesn't happen to mine I am at almost 7500 miles.

[subxero]

i have a 12 with 6k on it. no problems yet

[drphils87]

I really think I piece of debris kept the clutch from releasing, because I remember it made the loud teeth snapping sound right when it fired up. Of course your theory fits too, but mine is more likely since I couldn't move my big gear attached to the clutch, but I got the flywheel off with the gear and clutch and the clutch worked fine, it wasn't locked up.

[mgentz]

One way or the other the gripping mech on that gear got stuck.
