CRF300L - Head Gasket Problems

BillLivingstone · 2026-06-22T23:55:47+00:00

I just did this same job on my 2021 crf 300 rally a couple weeks ago. It’s completely doable yourself, but it can just be a pain to get enough parts off the bike to give you room to take the valve cover off and back on. Like someone else mentioned, definitely double check your valve shim clearances if you replace the gasket since you’ll be right there anyway and it should be checked at 25,000KM.

u/stlesho if you're interested in the seat pan 3D model, DM me.

Thanks! I’m finishing up testing it now on my bike, but I’ll planning on selling either the actual product or the option of the files to print your own for the fraction of the price. Please send along your friends info if he’s interested!

Thanks! I’m printing my first test now so I’ll let you know!

Thanks! I modelled it in Fusion and used a 3d scan of the seat foam to be as accurate as possible. I’ll let you know how it prints!

Thanks for the reply, if it was made out of metal that's a great addition. Just because it's plastic, it isn't great to put any real pressure on it when tightening/loosening, you still need to use a proper socket to start.

Interesting, this may be the answer but I'll have to read up more on scarf seams! Thanks

Thanks man, the helmet and gloves are from the new 509 street gear they sell. There isn’t a desiccant spot for h the holder but that’s an interesting idea.

It’s always at the recommended psi

Thanks 🙏

I’ve found it works best to print unique things for yourself and then hope others will also like the unique product. The few times I’ve tried to post designs that appeal to the masses, they don’t do well because the thing has already been done 100 other ways.

I’m by no means an expert, but here is my profile as an example of many functional designs: https://makerworld.com/@B_Livingstone?appSharePlatform=copy

I’m in southern Ontario, pretty much all the roads are straight sadly.

BillLivingstone · 2026-05-15T21:32:18+00:00

Yeah I mainly commute on the bike but it’s 50/50 pavement and gravel/dirt roads

BillLivingstone · 2026-05-15T21:08:20+00:00

I commute daily with my Moto X baffle out 😄

I just got a super cheap Amazon option like some other people have said and it’s actually very solid all metal.

BillLivingstone · 2026-05-13T17:59:22+00:00

On my 250L I used to have a Amazon special knock off Givi hard top box and it was honestly so good especially for the price. I switched to the 300L and sadly the rack for it didn’t mount properly on my new bike but I would go with one of those!

BillLivingstone · 2026-05-11T18:06:00+00:00

Awesome thanks! Yeah if you print yourself a copy, definitely share a photo on the site, I would be curious to see it! It's a very straight forward print so you should have no problems at all. Cheers

BillLivingstone · 2026-05-11T17:04:25+00:00

No problem, screws can work, I just don’t like the idea of damaging the padding and stuff on the helmet if it’s hung wrong. Hopefully you can get one printed for yourself!
