One more thought: Maybe a "shield" from shielded bearing came off of the bearing. I would check your bearings after removal and see if they have a "Z" or "ZZ" in the bearing ID number.

I'll take a wild guess: Those fragments look like pieces of JB Weld that were formed for a purpose. I would check you fill/drain areas and the cases in general to see if there was a repair inside that maybe failed.

Can the motorcycle be kick started?

Great article in Trail rider Magazine written by Rachel with her story that brought her and Rieju to the FIM EnduroGP Women's World Championship...

Rachel Gutish wins final Enduro GP in Germany bringing home series championship for Rieju while fellow Rieju rider Rosie Rowett finished second overall. Excellent showing for the new 300i to compete and finish in an FIM Championship. With this win, Rachel becomes the first American to win an...

Glad to hear you are on the road to recovery without surgery. As for "horror stories on braces": There are horror stories for everything we do on a dirt bike so I would just accept that slight risk and move on...I've heard about all the horror stories associated with hand guard/bark busters...

I just saw that at the conclusion of the 2025 ISDE, the USA women's team secured victory by 30 minutes or more. She (Rachel) appears to have been riding a 300i. Coupled with her victory in the 2025 Tennessee Knockout event a short time ago, she is representing Rieju USA well in competition...

For the rod kit, a 1983-2001 Honda CR 250 rod works...Plenty of those out there! If you just want a dealer to get you parts, try Motocenter AZ in Mesa, Arizona. They have sold lots of that year GG and plenty of Riejus. Number is 480-642-6686. For crank bearings, search this site and the...

Congratulations! Post a picture of your bike when you can. I may have some new and used fenders for that year trials! Picture is of new fenders and I have some used fenders in decent shape.

That looks like Colorado! Is that Gypsum Hardscrabble?

The ATKs are good bikes. My e-start stopped working a while back and it turned out to be just replacing the starter fuse and cleaning up some ground wires. It has been undergoing a complete overhaul for a few years as the main shaft wears a lot if you don't keep an eye on the countershaft...

Had an older Lectron and hated it as it totally flattened the power. Newer one does have some adjustment on Power Jet so that MAY help prevent a seizure during extended street riding. Modified choke circuit with cable: That MAY help but it's a stopgap and not a solution. Richer fuel/oil: That...

It is necessary for the 300 if you have it jetted/tuned for riding trails for which it was intended. Enduros and motocrossers are jetted/tuned/geared for slower but more "sudden" obstacles where we want responsive power. Scooters and 2T street bikes are jetted/tuned/geared to be ridden in a...

I would never do that with either of my 300s. I had to ride my 2014 EC300 for 15 miles of 60 mph highway with a group of others and we kept it at 55-ish and the 2014 had the stock choke lever on the handlebars. I tapped that lever every 5-10 seconds to keep it from seizing. I don't want to...

I recently rode a friends 2004 GG 250 and noticed the same thing and I was trying to figure out why it was like that...If you get yours diagnosed and fixed, please post what you find out to be the issue!
