CRF250R 2010 Crankshaft option

After 35 hours, I saw a very little ammount of sand grain size cooper particle in my oil filter. So it's the off season here and I'm won't trust my crankshaft for another season.

I want your opinions on the some option I have.

1-Hotrod connecting rod with static balancing 250$

2-Honda crankshaft 300$

3-Falicon or Carrillo connecting rod with static balancing 400$

4-Falicon connecting rod with dynamic balancing 650$

I'm a novice track rider with some trail ride. I check for something bulletproof for the next 100 hours, but not sure I want to spend 600$ unless it's really really really THE option

Go with #3 option. At that point, you would be having your stock crank re-fitted with either a Carillo or Falicon rod and bearing. Great set up and your crank has already been heat cycled equaling a much truer balance.

By the way, you caught it at the right time. Whatever you do, don't start that engine again. You could be looking at much more than just a crank and bearing if you attempt to run it. It's now a ticking time bomb. Please take my advice on this last paragraph. If you don't, you'll wish you did. I've seen this movie before.

Believe me, I ever rebuilt a complete engine with a clogged oil pump. I'm not gonna take a chance with it. The third option is the one for now I like. Not really more expensive than a brand new unit, but better than one. With this option I'm able to rebuild it for 800$ new top end include.

Since my 450R failure, I ever open my oil filter and inspect the paper after every oil change, so every 5 hours. So I'm really happy to catch it so soon

A friend of ours had a falicon CRF450 crank snap in half at the crank pin. So I'm not convinced there is any tried and true best crank option.

Check what happen to my crankshaft. Finally the ''cooper'' particul in my oil filter was....rust

      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.

      Hi all,
      My main question is how can I make my 250r more reliable. I have owned it for 2 years and it was spent about 1 year in the shed probably needing new valves and piston rings (i have been putting it off) Will steel valves last longer and work well in the engine? Also, what are your thoughts of me selling it and buying something newer? is it worth it?

      I checked the valve clearance on my 06 crf250r and both exhaust valves is at .007 and the intake is (left side) .005 and (right side) .000??? idk my feeler gague only went down to .002 and it would not slide in.
      Is that ok for the exhaust? Do I need to just shim the right side on the intake? or does both need shimming?
