I thought i had everything worked out. If you'd read my earlier posts you'd see  I bought a bike with 13 miles on it, but its a 2000. I had some trouble starting it fixed was running good. took it for a ride. Ride was amazing running perfect. On the final 2 miles home I was shifting up from 2nd to 3rd the bike stopped running and the rear wheel locked up I skidded about 15 feet. The kick start will go down now, but it takes a lot of effort. A teenager who saw it happen says he rides motocross and it is the crank or a piston. Keep in mind this bike has under 100 miles on it. Oil is at correct level,  valves adjusted properly, just cleaned carb, new spark plug. Any advice???

Man!  That's terrible.

I have a bunch of profane words I would give to you for the asking.
You've probably used up your ration of them so feel free to use mine any way you want.
You can use as many of them on your bike as you wish.

How fast were you going ?

Do you have a service manual ?

 

[jayrobbins]

35mph

I was accelerating

Open the oil filter,examine the oil, filter and any sludge.  Open the sump drain bolt, catch the oil, examine all these oils, filter and sludge for any shiny metal bits.

Report back here with results.

[jayrobbins]

I will tomorrow,

[jayrobbins]

please help

Tiny bits of metal will probably be found because as was mentioned in jay's earlier posts the bike is a 2000 but it only had a few miles on it.

During that stage of its break in a lot of shiny bits is pretty normal.  At least it was on my 2011 G5.

Again, I don't own one of these older RE's but the lock up might be due to either the engine or the transmission.

If it works like I think it does, putting the transmission into one of the gears, pulling in the clutch and pushing down on the kick starter should result in the kick starter moving down.
Then, repeating this without touching the clutch lever probably will end up with the starter lever not moving.
Remember, the transmission must be in gear before doing this test.

If the kick starter lever refuses to move while the clutch is pulled in it would indicate to me that the transmission is locked up.
 If the kick starter  lever does move down with the clutch pulled in  the transmission is most likely OK.

Jay said he was shifting from 2nd to 3rd so if the transmission is locked up it could be in two gears at once.  Of course, I don't know about these RE's so maybe that is not possible but on many gearboxes if a shift yoke breaks so it doesn't pull one gear out of engagement with another while another yoke pushes another gear into engagement with another it can lock up the whole thing.

I am just  hoping for something that might be pretty easy and pretty inexpensive to fix.

Thanks for the info. A update. Checked both engine oil and oil in main drive both are clean and look how they should. Also with the clutch in it does freely move.

[Arizoni]

Well, damn.
I guess this is where I get off and leave you in the hands of the experts who really know about these older models.

Here again, I don't know about the older RE's but the new UCE's use rolling element bearings in all of the lower end and transmission.

Ball , roller and needle bearings almost never seize up due to a lack of oil.
If your bike is similar a frozen bearing would be very unlikely.

Was there any unusual noise just before it locked up?

[jayrobbins]

Not that I can recall.

Three things you can do to determine what it is or is not the problem;

 Remove the primary chain case cover a.k.a. outer primary and take a peek inside to ensure everything is proper.

Remove the timing chest cover and do the same there.

Remove the petrol tank followed by the head and cylinder.

 

[jayrobbins]

I removed all three and inspected. No issues that are visible. One again all oil looked good.

You probably had a piston seizure.

With a non-broken-in bike with just a few miles on it, and the heat wave temperatures being as they have been, and any kind of brisk riding, and it is possible to seize.

I would get an owners manual, and follow the break-in instructions.
You can't break that bike in like a modern bike.
You have to ride very slow and "granny-like" for hundreds of miles to break that bike in correctly.
