Every brazilian crf's comes from factory with no diffuser and snorkel.. and, we used to drill a 25~30mm (about 1") hole at very bottom of the spark arrester (then re-jet the carb).. the improvement after doing that simple mod is reeeally noticeable!! Great Video!! 👍👍
Good vid, I did the same mod to my 2007 crf150f on my channel. Easy, cheap and much improved over stock. Your words at the end are so true. So many people just gut the exhaust and pull the snorkel without doing the jets. This only makes the bike louder and probably results in an actual loss of some power. I agree with you. Buy the jets, they are cheap.
Just got my 2003 model, it looks great butt runnin' like hammered dog dookie. It was running great for 5 min yesterday, then it just crapped out. Thanks so much for sharing this sir. Take care, from Tn.
The first thing I did when I bought this bike in September was put on the FMF PowerCore pipe and jet it. I definitely recommend not just modifying the stock pipe but actually piping it. It made a huge difference in performance and helped a lot with the very "electrical" sound that this bike has, which I hate. Of course it costs more than just modifying the stock, but its definitely worth it in the long run. Great video!
Thanks! I've been looking at that pipe for this bike! It's on my list of things to do but possibly after a sprocket upgrade and tubeless tires. Just got some Pro-taper SE bars to replace the stock ones (they already bent on me). Good luck with yours, they're great bikes.
Dude that electrical sound is the alternator charging the battery when the moter turns I think, its so annoying you shoudl watch some of my videos the bike sounds like a hybrid,
Ok I might install the power up kit, I live in Australia and I have no idea where to buy this kit from and since I'm under 16 I cant just go to the local Honda dealership with out my family, is there anywhere you can buy it online in Australia, and is it easy to install, because I have no experience. Thanks
Great video, thanks for sharing. I own a 2014 and was wondering if it can be done since ive just seen older bikes. How much is the gain?? Is it noticeable?? Also what altitude you're?? Since ive read people tend to use 120. I live in 1500 ft altitude.
Easier to start, better response, more power. I was fortunate enough to have another stock 230 around to compare it to as I made changes. It's very noticeable. I'm at around 950ft but I do a lot of my trail riding around 1500+. 120 works fine for that.
cow productions you should be able to purchase everything from ebay. You can pause this video on the shipping paper and search for those part numbers. Or, just search for "CRF230F power up kit". There are also some companies (like Dynojet) that sale jetting kits. The process isn't complicated but does require a little carb knowledge if you have to diagnose problems (too rich/lean, bogging, etc). Do a bunch of reading first.
Jesses Bradshaw Hey do a quick search on Thumpertalk to see if there were any changes in 2017. My guess is the same jetting will be fine because they likely haven't made any engine/carb changes.
Thank you for providing these tips. However, the statement to use “either” the 2003-2005 needle OR the Full Power needle is not quite accurate. The Full Power needle has a wider taper than the stock needle and therefore requires using a much larger main jet (132) than using the stock needle (120 main jet.). After trying both needles, using any year’s stock needle with a 120 main jet/45 pilot jet works better than the Full Power needle/132 main jet. Using a Full Power needle with a 120 main jet will cause a very lean condition resulting in poor full throttle performance. The optimal main jet used depends on the needle used. Don’t mix/match them. Any year stock needle can be used effectively. The 2003-2005 usually works best with it’s clip in the fourth groove, counting down from the top. Any year after 2005 has a needle with only two grooves, however the taper is the same as the earlier years. Placing two 3mm washers (Ace Hardware) below the clip positioned on the second groove raises the needle to approximately the same height as the earlier needle/4th groove. So, any stock needle will work well with a 120 main jet at sea level. The bottom line: Most agree the stock needle (4th groove (or shimmed 2 groove needle)/120 main jet/45 pilot jet works best. The Full Power needle/132 main jet combination also provides much better performance than stock, just not quite as crisp as the stock needle/120 main jet setup. I’ve tried all these combinations, and can verify the results personally, which match the results reported by many others. This assumes sea level altitude, and that the other “uncorking” steps outlined in this great video are completed. I also chose to retain the exhaust diffuser to keep the bike quiet. It’s important to fine tune the fuel screw, but starting with it 1 3/4 turns out from gently fully closed will usually get you close. For more great tech tips/information about the Honda CRF 230f, visit the “Thumper Talk” website or app. It includes great information from many knowledgeable 230 owners/tuners. Thank you for making this helpful video! These are great bikes, and the simple uncorking really wakes them up, as well as improves their durability by correcting the lean stock jetting.
I've recently begun to mod by CRF 230 L and I have heard people say that removing the baffle and snorkel without rejetting can cause issues. Is it a backpressure isssue? I'm curious to know why it hurts the bike.
An increase in airflow (removing the snorkel) will cause the bike to run leaner. If it's like this bike was, it is already lean from the factory. It's possible to damage the engine from this. Just removing the baffle will probably not cause an issue but I kinda like mine quiet :)
Hey I live at around 200ft altitude and do most of my riding at maybe up to 300ft. It is winter right now where I live too (my bike is running extremely lean with the altitude, temperature, and factory jetting). What jets do you think I should get? Like do you think that a 120 main and a 45 or 48 pilot would work fine?
Yeah, I would go with the 120 main, maybe get a size bigger and smaller for testing. And 45 and 48 pilot. 120 + 48 worked well for me, I'm at around 950ft. The "Power Up" suggested main is like a 132 or something but I and many others found that to be way too rich.
+sequret process is the same but I believe the 230L has a different carb. Try the DynoJet kit or searching on Thumpertalk. Those guys would know better than I.
***** I wouldn't think so but I don't know. I'm sure someone has tried that combo. Take a look on thumpertalk on the 230 forum. Let me know what you find out.
Wow, this Google+ TH-cam integration is rather frustrating. I'm not sure how to reply directly to you cow productions since I see no reply option. To answer your question, a lot of people remove the baffle without re-jetting, I personally wouldn't. Removing just the baffle will yield only marginal performance improvements if any. Keep in mind the additional sound may make you feel like your going faster when you really aren't. In my opinion, the additional noise is not worth the gain from just simply removing the baffle and I'm not sure of any long term consequences. If you do it, read your spark plug frequently to check for lean/rich conditions.
I did the same to my left over 2014 10 mins after taking it off my trailer hahahah. I'm about 1280 sea level an same evening you did hear other than I put from crfs only they sell a longer air fule screw makes it much easier to adjust even Will riding. but you have to reed your plug any sign s of white flaky deposits you're still running too lean check out jets R Us he has an awesome write-up on how to read plugs I'm running a 132 Main jet an a 45 an mine is spot on for summer riding an when it gets cold I bump it up to a 135 an spot on again everything comes into play humidity altitude hot and cold you just gotta know how to read the plug that's on any Bike generator weed wacker an lawn mower. lol. nice video by the way.
+Brandon Setzenfand Good to hear, they are awesome little bikes. 132 was way too rich on my bike but I'm sure it differs. 120 was about the perfect balance. Different jetting combinations have been tested and dynoed here: www.thumpertalk.com/topic/137569-sticky-jetting-the-230f-power-up-kit/
YES! It’s especially important to rejet if you put a more free flowing exhaust on the bike. Less restriction improves exhaust flow/power and requires more fuel flow. Opening up the exhaust without increasing jet size not only robs you of “free” power, the resultant lean fuel mixture can lead to excessive engine wear, or even damage.
@@aussietin55 Sorry, but this isn’t accurate. It’s even more important to increase main jet size with a more freely flowing exhaust. Increasing to the proper jet size also provided MUCH better power.and engine reliability.

Do you still have the airbox air filter snorkel or whatever that thing is?
You don't need to take those 3 screws to remove the diffuser, just hold it up with one finger while you take off the screw holding it to the pipe

I have a 2017 and I really don't wanna do the work looking for the jets 😩 it's so new I haven't seen anyone do it yet

This is accurate good info, thankyou sir.
Do you have to adjust fuel air mixer when re jetting? I’m wanting to re jet mine but I hear it’s hard to remove the cap for the air mixer
I believe I did. You can pull it out with a wood screw or similar.
Can you pry it out? And under it does it take a normal socket or something different?
did you use the stock needle

SoftwareDevJason Hey thanks! Would the Honda Power Up needle work with my 230? It's a 2017.
Jacob Chaplain I think it works fine. A couple guys online recommended the earlier 230 needle instead though. I doubt I could tell the difference.
@@SoftwareDevJason Yes the 48 slow worked for me too
just cut the diffuser right at the holes so you just have the bulb, keeps the sound down.
Did you make any changes to the gearing or footpegs.?
Gearing and footpegs are stock. Footpegs I definitely wanted to change at some point.
this may sound like a stupid question but im new to dirt bikes so what does the defuser do?
+IAN CROCKER Creates back pressure in the exhaust and makes the bike quieter. Also referred to as a baffle in most cases.
thanks!
any insight on how similar this job would be on a 230l
+sequret process is the same but I believe the 230L has a different carb. Try the DynoJet kit or searching on Thumpertalk. Those guys would know better than I.
Did you put the clip in the center position on the needle or further down?
Second position from top if I remember correctly. I can verify later tonight in my notes.
SoftwareDevJason I'm planning on changing the main to a 125 vs 120, 45 pilot, you think I'd need to move the needle ?
Correction. Clip in 4th position from top I believe.
