Manual actually recommends running 30:1. I run Maxima 927 at 32:1. The JD jetting kit and the recommended setting in that kit are critical to a good running YZ125. Mine runs perfect. I am now running a Smartcarb, and even better. It also makes a big difference in overall power and smooths out the power a little. But it's very expensive. JD Jetting kit at the very least is needed for this bike to run really good.

@@GOATbro_Australia sick thanks man. Can you drop the smart carb link ? I think I’m gonna go that avenue just looking at my options on it and where to get one.

I probably didn't need to, but I did trim a little just to be safe. If you take your airbox/subframe off, you can mount the carb to the airboot. If you spin it around, you can see if the rear ports clear the inner lip. Also, once installed, your shock spring will rub slightly on the airboot at the very top of the stroke. Some are sanding a spot down to clear it, but I have not found a need too.

@@GOATbro_Australiaalright sweet thanks for the fast response I’ll run with it I’m sure some 3m tape or something would be a little extra barrier but once you sit on it I assume there’s daylight

For the boat part only, I have a 12 foot high, X 10 foot wide roller door. The bay is 26ft long.

You can with a Speedbox chip.

I have a few eMTBs and the overall quality is very good on the HC5. I think the battery cover could be better for sure, the charging port cover is not great, but they changed that on later models, and the stock pedals are junk. Other than that it has held up well after 150 miles. I really like it. It's hard for me to compare it against other bikes, but I would say it's good value for the money, and should last a very long time. Hope that helps.

@@GOATbro_Australia cheers bro… thank you…

I hear ya! I was pissed too. They did repair mine and did cover all costs, but I can't blame you for wanting a new one. Anyway, mine has worked without issue since being repaired, but it was a pain. Once working, it's a great rifle, but it should have come that way from the factory for the money you spend.

I jetted it to the owners manual recommended settings for my riding conditions and installed the RAD Valve at the same time.

@@GOATbro_Australia Right on. Just curious - The Rad Valve manual suggested a jetting change? I'm asking because I recently purchased one but the manual wasn't included. And Boyesen didn't get back to me. I've read mixed responses from people. Half saying no. Half saying the opposite. I appreciate the response. Big time.

@@HexBMX I never saw any recommendations for jetting changes. I would just jet to what your manual says for your conditions, and you should be good. Running with 32:1 mixture. That's where I would start. Worked perfect for me.

@@GOATbro_Australia Thanks. Yeah, I'm going to drop the main jet down one and see how it does. It's running the stock pipe except for the FMF Powercore silencer. It's also running well now. So it should be relatively easy to dial in. But I can see the reeds are ready to be changed. I appreciate the responses.

If the bike is on a stand and the rear suspension is fully extended, it might rub slightly. The actual length of the carb is the same as stock when I measured, so I am not really sure why it would rub, but yes when the suspension is fully extended it seems to rub slightly. Probably not much of a concern. Maybe contact SC and see if they have more insight into this.

@@GOATbro_Australiasweet thanks for responding, I ended up trimming the airboot because I was paranoid and didn’t wanna have to rip it apart again

@delayeddeyhaus7720 so your happy with it now? Keep me posted.

​@@delayeddeyhaus7720 SmartCarbs are slightly longer end-to-end than stock due to routing the vent passages internally. There's only so small it can be shrunk before running out of room for those passageways. That said the longer length is typically a non-issue. Slight airboot/shock spring contact is permissible and will only result in the boot shining up over time. The spring doesn't move enough to cause any actual wearing through of the boot and is at its worst at full extension up on the stand. Removing the reed spacer, if present, will shift the carb forward and away from the spring. In general we don't recommend running the Boysen RAD valve in conjunction with a larger-than-stock diameter rear shock spring. Doing so really limits the amount of room for the carb. Happy to answer any questions!

@@SmartCarbFuelSystems ya I ended up sanding down the outside a bit but stopped and just threw it on. Once I sit on the bike there’s not much contact if any. Started 2nd kick and it runs better just out the package. Still not perfect but I’m gonna let it break in a bit before lean it out a click or 2

I won't go into exact details, and I don't actually remember without digging up all the paperwork, but I paid roughly $12k below MSRP. Keep in mind that was 12 months ago, and the MSRP can increase one or more times a year.

Go Aussie! Moving back soon!

Yeah, sorry about that. I need to do better next time. Thanks for the comment and for watching

Sorry yes, I did test the kit, and no complaints. Ran smooth and clean. A definite improvement over stock. It's worth the money. As for the Smartcarb, that was mostly to satisfy my own curiosity and it surprised me. It added significant power across the board, especially on the low end, and runs even cleaner and smoother than the JD kit. In my opinion, it was worth the expense. The JD kit is certainly worth doing if you can't afford a SC. Hope that helps, and sorry again for that lack of detail.

Thank you! It's holding up great. We are really enjoying it. No issues.

Yes it runs my whole house including AC and our Well pump.

I don't have the standard insert, so I can't say, but assume it would not.

I can't say that it does. I don't have the standard insert, so unfortunately I cannot really say.

They want to save money.

@@GOATbro_Australia you’d think they’d want to make the best engine possible to compete with the Austrians

Why? They are visible to the public when out on the road

Medium, 5-10

I think you would be happier in the long run with a 125. The KX112 would be fun for a while, but you would get your money's worth from the 125. Just my 2 cents. Hope that helps!
