Locked Up 2005 CRF250R

I have a 2005 Honda CRF250R that I purchased from a good friend just about a year ago. During that year I rode it maybe 5 times. During my most recent ride I noticed something odd. I was doing some free riding up north of family property when my bike didn't seem to be responding correctly. I pulled off and figured I had run out of gas, but to my surprise my tank was  nearly full, and yes the gas was on. So I thought maybe it overheated. I checked the coolant and it was fine. So I took a break from riding and let the bike settle. After about 30 minutes I went back to the bike and tried to kick it over. About every 5th kick the kick-starter wouldn't budge at all. It would take some muscling, but it would kick over, shut off and "lock up" again. After about 5 failed attempts I left it for the rest of our trip. I got back home and drained the oil and noticed some brass looking metal shavings in the oil. So I took off the left side crank cover and noticed metal flakes all in the bottom. I'm wondering what it was and what this means. If ANYONE has any ideas of knowledge of this it would be greatly appreciated. Here are some pics of what I found.IMG_0416.jpgIMG_0415.jpg

Your rod bearing is gone I have an 04 that's locked up right now trouble is they don't hold much oil. You probably had blow by like me and it got too hot in there and the rod bearing locked up. I bought a wiesco kit on ebsy for 350$ it has piston rings crank gaskets everything you need me sure piston and rings are replaced or it will happen again. The problem with blow back or blow by is its not noticeable. I'm in the same position as you at exact same time same bike too lol. The kit for the 04 fits the 05 and 06 too do you'll get the sane thing. Are you good with rebuilds??

Lower crank bearing went. Don't kick it over anymore. Rip the engine apart and plan to replace the crank or the bearing and rod. Hopefully the metal filings didn't damage anything else in the process.

Well the kit was created by wiesco it replaces all bearings so I think he should replace it. It needs a piston and rings to stop the blow by though so it doesn't lock up again

Bit yeah if you keep kicking it it'll damage your crank case they went cheap from Honda

Damn, $350? I guess I shouldn't complain it could be worse. Rebuilds? I've never done one before but I have a service manual and I'm pretty confident I could do it, maybe with some help from a friend of mine. How do I go about this whole process? Just start tearing it apart? Or is there only one specific region of the motor I need to focus on?

Timing you have to get everything back in how it came out

When you take the valve cover off take a sharpie and mark the camshaft sprocket and chain where you can see that's where they meet

lkeffersyz: what exactly was the kit? was it a piston kit? a crankshaft and connecting rod kit?

I'll send you the link hold on one min

      Rockstar Energy Husqvarna Factory Rider Starts his Quest to Defend Cross-Country Rallies World Championship
      March 15, 2018 – (Motor Sports Newswire) – Rockstar Energy Husqvarna Factory Racing’s Pablo Quintanilla will re-start his 2018 international rally racing campaign on March 24 to 29 at the Abu Dhabi Desert Challenge in the United Arab Emirates. Working hard towards returning to full competitive fitness following a foot injury sustained during the closing stages of the Dakar Rally, Pablo’s teammate Andrew Short is expected to join the Rockstar Energy Husqvarna Factory Racing squad at the 2018 Merzouga Rally in mid-April.

      With the Abu Dhabi Desert Challenge playing host to the opening round of the 2018 FIM Cross-Country Rallies World Championship, the event in the UAE will see Pablo Quintanilla begin the defence of his FIM Cross-Country World Championship title. Securing eighth overall at the 2018 Dakar Rally in January, the Chilean rally star is already looking forward to a solid return to racing aboard his FR 450 Rally machine.
      Successfully wrapping up his debut participation at the prestigious Dakar Rally with a top 20 result, Andrew Short has been recuperating from a fractured tibia and fibula on his lower right leg. Resuming his training sessions in the middle of March, the American has his eyes set on making a return to racing at the Merzouga Rally on April 15/20, in the dunes of Morocco.
      Celebrating its 28th edition in 2018, the Abu Dhabi Desert Challenge is a six-stage-long rally taking place in the southern part of the United Arab Emirates. Kicking off with the traditional Super Special Stage on Saturday, March 24, the event will continue with five more days of racing in the Liwa Desert before competitors reach the finish line inside the Yas Marina circuit on March 29, 2018.

      Pablo Quintanilla: “Abu Dhabi will be our first race after the Dakar and I’m really looking forward to it. It’d be good to start the season carrying the #1 plate on my Husqvarna as the reigning champion. With it being the first race for the new season, it is important for everybody. My goal is to get a good race pace from the beginning in order to be inside the group of leading riders. The season will be long and my plan is to continue improving my pace as the racing goes on. I want to get back my racing speed and also remain strong throughout the event in Abu Dhabi. Taking place in deep sandy dunes, the Desert Challenge is always a tough event and it is also highly probable that we will have to race in high temperatures. It’s going to be a challenge but I’m looking forward to it.”

      Jeremy Martin Leads the Charge for Wiseco Riders at Daytona Supercross
      Christian Craig Turns in Career Best in 450 Competition
      MENTOR, Ohio (March 13, 2018) – Jeremy Martin showed the way for Wiseco-sponsored riders in Saturday night’s Monster Energy Daytona Supercross presented by Honda. In a season marred by bad luck and misfortune, Martin put together a near flawless ride to earn his first Eastern Regional 250SX Class podium finish of the season.
      Martin qualified eighth for the division’s annual visit to the World Center of Racing, finished fourth in his heat race, and came home second in the 250SX main event, missing his first win of the year by less than a second.

      “It’s Daytona, a real man’s track.” said Martin who sits fourth in points. “It was the toughest race of the year as far as fitness. I had to slow down a little bit, halfway through the main. I was getting close to (race winner) Jordon (Smith) and I was starting to think about where I could make a move on him, then I made some mistakes and he got away from me. Couldn’t quite get close again, but it’s good. We’re on the podium and in contention for wins again. That’s something I haven’t been able to say in supercross in a while. We want to get wins and now we know it’s coming.”
      Martin’s podium was a bright spot, but the rest of the event was rough for the GEICO Honda/Factory Connection squad. RJ Hampshire crashed hard in his heat race and had to be transported to a local hospital. He injured his back and ribs, but shoulder pain left him with the most concern.
      “I felt good on the bike all day,” said Hampshire via his Instagram account. “Had some pretty good speed and my foot just slid off hitting my shifter in those rollers during that heat race. After seeing the pictures from the crash I’m very thankful I didn’t take a shot to my head. I have some fractures in my T3/T4 in my back and ribs. Also have some damage to my lungs which is why I’ll be spending a couple nights in the hospital. I’ll be getting some more checkups this week on the shoulder also.”
      Cameron McAdoo, the third member of the team, was unable to compete at Daytona after being sidelined with a hand injury two races ago in Atlanta.
      Across the paddock, in the premier 450SX Class, Christian Craig got the call to fill in for Team Honda HRC. With the team’s regular riders Ken Roczen and Cole Seely out with injuries, it was up to Craig to carry the load for the factory team, and the upstart rider didn’t disappoint.
      The San Diego native was solid in both qualifying sessions, won his heat race and snagged the holeshot in the division’s main event. After relinquishing the lead to eventual winner Justin Brayton, Craig continued to show he was up for the challenge. The 26-year-old rider raced for second and third for most of the 20-minute-plus-one-lap feature before losing one more spot in the late goings to bring his No. 32 Honda CRF450R home fourth in the final rundown.

      “I had a great week testing with the team,” commented Craig. “They came down to Florida right after Atlanta and I feel like we really improved. Just getting more time on the bike and getting more comfortable was huge. I started off race day feeling really good. My qualifying position didn’t really show it, but overall I was happy with my riding. It’s all about having fun out there, and man, that’s what I did tonight. I was up front in the heat race, fell to third, but then the two guys in front took each other out so I ended up winning. You can call it luck or whatever, but I just put myself in a good position to capitalize on people’s mistakes."
      “I had a good gate pick and some confidence going into the main. I grabbed the holeshot and led for almost the first lap, but [Justin] Brayton got by me pretty quick. I stayed second for quite a while. I just rode my hardest and did my best. Unfortunately, a couple guys got by me so I ended up fourth. The track was so tough. This is only my second time racing Daytona and last year didn’t go well, so I really wanted to get some revenge this year. It’s better than the week before, but man, I was so close to a podium. I just need to keep putting myself in good positions and work on getting better each weekend.”
      Monster Energy AMA Supercross rolls on this weekend when the series visits the “Gateway to the West” for its annual race at the Dome at America’s Center in St. Louis. The 11th of 17 races on the 2018 supercross calendar will be televised live on FS1 Saturday, March 17, beginning at 8 p.m. Eastern Daylight Time, 5 p.m. Pacific.
