Signal Rotor FIXED!. Starting the engine that was drained...another problem

[adidasguy]

I hit it with an impact wrench just for good measure as I had one come loose 2 weeks after installing to torque spec. Though that was the first one I did. I didn't clean the surfaces properly so there was oil in there. Now I also score the surface a little with 400 to 800 grit sand paper. Just enough so the surface is not polished as when spinning loose, it polished the surface very smooth in a circular way.

I don't recall the impact wrench turning the bolt at all. I think the impact wrench has less torque that 130 nm. Its the hitting of the impacts that maybe insure everything is tight.

Leave it. If over torqued, no reason to take it off. That is such hard steel you can't damage it without lots  and lots of work.

SOUNDS GREATTT! At what spec does the stator cover bolts need to be torqued to? I realize you mentioned that in the video.

[adidasguy]

I forget the cover bolt spec. It is not that much. Those small cover bolts into aluminum can't hake much before they strip out.
I only remember the rotor bolt 110-130 nm.

I installed the flywheel. put oil in her. ( this is a drained engine that has been empty for 2-3 weeks now). I hit the ignition but it sounds really odd. I could smell burnt fuel. the bike started to crank but wouldn't go all the way.

Oh, dear....

[junk301]

it does seem like something is spinning. maybe the flywheel isn't on properly. I'm not sure

[junk301]

too add my throttle is extremely tight, would this stop the bike from starting? the burnt fuel would mean that the flywheel is working, correct? I'm just assuming its having trouble starting since it was sitting without oil for so long. I will post a video on how it sounds.

Watch my new video on installing it. maybe it is not on tight?


Fixed Suzi's loose starter/generator rotor and made a new video of the repair.

I followed hour video. the bike is cranking but its not catching. I don't want to drain the oil just yet. I will upload a video tomorrow on the sound its making.

[adidasguy]

You can remove the right side timing rotor cover (no oil is under it) and see if the crank shaft is turning when you hit the starter.

[junk301]

Yeah it was turning with the starter. I will post a video tomorrow. thats when ill be working on my bike. When I did try starting it I did hear the exhaust pop once or twice. Is there any way the timing rotor could be the issue?

Is there any way the timing rotor could be the issue?

Yes..... see my earlier comment.

Those new holes in the crank and the rotor need to be precisely, that's........ PRECISELY!!! 180deg from the originals.

The rotor only has to be a degree out of sync with the crank to effect timing.

You need to check the timing marks before you go any further.

The procedure for timing F`s has been covered many times, here is just one of them....

thanks sledge, I will open up the valve cover and check. however would the exhaust even pop if the timing is off?

Whatever it is, it doesnt sound good at all. The throttle cable is completely stuck even after loosening it by the kill switch box and at the carbs. Compression is fine in both cylinders, the spark plus are firing.

[junk301]

im going to inspect the flywheel. I feel like the gears aren't meshing properly

[adidasguy]

Sounds to me like the generator rotor is loose. It catches a little and turns the engine, but not a really tight fit. It is slipping and catching as if there is now some rough scoring on the crank shaft allowing it to occasionally catch and turn the engine, while still slipping a lot.

[junk301]

yes that was my feeling. do you think any damage could of been caused. and when opening up that side do I need to drain the oil or can I just tilt the bike to the right

[adidasguy]

Drain the oil into a clean container to re-use it.

[junk301]

if it was loose. would I need to pull the flywheel then reinstall?

[adidasguy]

Absolutely. You can't tighten it down because now there is oil in it on the mating surfaces of the shaft. It must be clean. I score the mating surfaces with sand paper to aid in a tight press fit. (Give the crank a hand job with 800 grit paper).

Check the shaft and rotor for scoring and circular ridges and bumps. You have to remove those. The surfaces are a friction press fit. Perfect fit is important.
