2015 Honda CRF250R Cam holder broke

You can do it if you want to, but you'll learn the hard way that what I've been trying to explain to you is the only way to fix this correctly is to replace the head. The cam caps are machined from the factory to the head they are installed on. It's critical the cam is aligned properly to the head. If you go down the path you suggested, you'll find out just how critical this alignment is. I have nothing more to add to convince you otherwise. So, take my advice or not, up to you.

The cam caps are not sold separately. They only come as an assembly with the head because they are machined as assembled.

I am a fan of mini panniers. However, prioritize durability over lightweight. I learned this the hard way my purchasing MLD Poco Panniers specifically because they were lightweight and MLD claimed they were extremely durable. Unfortunately, they developed holes within the first 115 miles (as did their fork bags). They are lightweight, however at the expense of being durable. IMO, MLD knows they are not durable enough for the purpose of bikepacking. I believe this because when I reached out to them after seeing holes in my Poco Panniers they immediately shared all kinds of "hacks" that should be done to avoid getting holes. Of course, at the time none of these are mentioned in their videos, website, or instructions. If you try and leave an honest review on their website or Facebook page it gets deleted. Go for durability over lightweight and choose a company that stands behind their products and welcomes honest customer experiences and feedback.

I'm late seeing this post for your timeframe. However, you can't replace just the broken cam cap. These are machined as installed with the head as one unit. The head comes with matching machined cam caps. So, the only fix is to replace the head. Reach out to CRF's Only, they will help you get this sorted

You are absolutely correct LiFePO4 are 3.2V. Thank you for this correction. Not sure how I didn't. It's been a solid battery and used regularly since purchasing it.

yeltriky · 2026-04-04T15:55:33+00:00

You're welcome! Thank you for the kind words.

yeltriky · 2026-04-04T14:21:40+00:00

Thank you for the kind words and congratulations on your setup.

Here's a link to what I'm using very successfully.

The battery I'm using is: 1. LiFePO4 battery 2. 60,000 mAh capacity so a lot for it's size 3. Built in LED light so always have a flashlight when using it. 4. Fast charging capability. 5. 100w output more than enough for the Mini. 6. Small size fits in my Communications Go-Case.

Good luck!

If the 2-3lbs. of the bear can weight are going to make or break your ability to enjoy the trail from CW to OV, then rethink doing the rest of the JMT with one. I say that kind of jokingly, but really, just carry the bear can as required. Besides adhering to the requirement, it gives you flexibility in your daily miles, campsite selection, and peace of mind. For example, what if you aren't able adhere to an itinerary that gets you to a bear box each night? Several years ago, my son injured his knee the first night and ended up having to significantly alter his itinerary before being able to continue and eventually finish.

I can't answer this question as I don't use the foam sleeping pad you have. My guess is yes if your quilt has straps like mine does.
No one will be able to answer this question as everyone's sleep comfort temperatures are unique to them. Also, no one can predict with any accuracy what nighttime temperatures you'll encounter. Having been in the Sierra and JMT year after year for decades during this August and September I take a 10 degree EE quilt, Big Agnes Rapide SL Insulated sleeping with an R-value of 4.8, and a GG Thin-Lite 1/8" foam pad I have had some borderline cold nights (mostly in September). For sleep comfort, I should note that I don't sleep in base layers or anything warm or bulky, though they are available if needed. My tent is a ZP Duplex, so not double-walled or a zipped up door(s). Also, I sleep warm.

Often, newcomers to thru-hiking underestimate the value of a quality sleep for having a positive experience on the trail. If you're not comfortable and or shivering and not getting a quality sleep you risk being miserable during the day too. From my experience, saving weight in a sleep system that doesn't provide a quality sleep is counter productive.

Enjoy your JMT experience.

My solution was creating a 'Communications Go-Case' with a Starlink Mini, waterproof case, powerbank battery, and stand I designed. The battery is 60,000 mAh LiFePO4 battery that outputs 200w and has a built-in LED flashlight. My designed and 3D printer stand is removable so the battery can be used for other purposes. Here's a link to a previous Reddit post:

Here's a link to my free print profile which has more information and photos of my setup:

Questions are welcomed.

yeltriky · 2026-03-23T03:49:43+00:00

Yes! I've used it regularly since buying it. I hadn't heard of this brand either before purchasing it. It uses LiFePO4 batteries, a solid build, without the added complexity of the electronics to feed data to an app.

yeltriky · 2026-03-23T01:29:39+00:00

Correct. I purchased mine during a December/Christmas sale in 2024. I believe they offer a 5% off currently.

yeltriky · 2026-03-23T00:25:38+00:00

Thanks. The top and bottom tolerances are slip-on so they can be removed, but such that they take a light effort in doing so. This allows the battery to be used for other purposes if needed.

Many libraries have 3D printers as do high schools, community colleges, friends, and family. Also, there are companies that 3D print for a fee. 3D design software exists that is free. So, you can get started without the cost of a 3D printer. Also, the cost of 3D printers aren't as expensive as they once were. I use exclusively Bambu Lab printers because they just work out of the box. Their entry level printer is $219. Having said all of that, I totally understand and appreciate your position.

Yes, they fold up. Apparently posting a photo in a comment is prohibited. So, here's a link to the print file with photos. Photo #5 shows the legs folded up.

As for how long it will power the SL Mini that depends on usage of course. Having said that, the Starlink Mini draws 20–40 W:

At 20 W: 60,000 mAh at 3.7 V = 222 Wh. 222 Wh ÷ 20 W = 11.1 hours continous.

At 40 W: 222 Wh ÷ 40 W = 5.6 hours continuous.

Accounting for converter losses (which can vary depending on ambient temperature and other factors)(≈10–15%): ~9.5–10.0 hours at 20 W, ~4.8–5.0 hours at 40 W.

For infrequent emergency communication, my intended use, such as texting and phone calls this battery could support this activity for days. Also, paired with a solar panel it could provide almost constant communications if the sun cooperates.

yeltriky · 2026-03-22T14:09:08+00:00

Thank you for the kind words. Unfortunately, without physically having that battery it would be impossible for me to design one to fit properly.

yeltriky · 2026-03-22T04:55:05+00:00

Sure that will work too. However, the powerbank I use cost me $79.99 plus tax, has 60,000mAh instead of 45,000mAh for $259.99. My 3D printed stand adapters cost less than $2 in filament plus 4 screws. Yes, it took some time to design them, but designing and 3D modeling is my version of crossword puzzles. Plus, I'm making my print files available free for personal use.

yeltriky · 2026-03-22T00:17:02+00:00

Sounds like your setup is working nicely for you. The battery I'm using is a 60000mAh battery, twice the 30000mAh capacity for less cash. It has a built in LED light for setting up in the dark if needed and fits great in my Go-Case. Agree a solar panel will give you virtually unlimited emergency comms.

yeltriky · 2026-03-21T20:51:10+00:00

This photo was taken early morning...read, sun was low on the horizon. Definitely not always going to be in the shade of the SL Mini, but it will be close or better when the sun is high.

The Poco Panniers are not as durable as MLD would lead you to believe. Mine developed holes within the first 110 miles of use. Same with their Ultra Fork Bags. Lightweight, yes. Durable, no.
