Honda CRF300 Power Up Kit

[@ShonkyProductions]

*In this I accidentally refer to the intake manifolds as a "Throttle body". It is just the intakes that are changed not the throttle bodies.

[@marcochavane3124]

Thanks again for making this. After fitting Level 2 Rally Raid with the heaviest springs they have and adding these mods I have the Ultimate CRF300L Rally. I've been flogging it daily and hitting single track whenever I can. It can really compete now. Raced a DRZ400SM with a slip on this past weekend and we were neck and neck all the way up until 70mph. We also did some urban exploring and I was right behind him the whole time. I have my little unicorn now. Just need a Standard non-DCT Africa Twin for longer trips on interstate and I will be happy for years to come.

[@ShonkyProductions]

Hi Marco, I'm glad to hear your bike is performing well now and that you are enjoying it.

[@bruceherring2753]

Thanks for posting this, especially the airbox velocity stack bit. I saw lots of other version that were SUPER hackish. I had already made a similar template when I fond this video, which gave me the pointers I needed to complete mine in a couple of hours with minimal fuss. All the bolt holes lined back up, boot is fully seated on the throttlebody, and only used a bead of permatex ultrablack around the exterior seam.

[@ShonkyProductions]

Great work. It's not too hard, but good preparation helps. Let me know what you think when it's all back together.

[@davingray865]

Looks really good mate. It is what you said. More power. Can never have enough in the sand and I'm the Rally racing setup

[@ride4adventure]

Thanks for sharing the project and building what looks to be an alternative dual sport bike to a KTM 690 Enduro R. Obviously there's a difference in power but that narrows significantly on the dirt. After your Rallies, it will be interesting to see how the performance mods translate to general trail riding and adventure touring. Lastly, a tally on costs will be interesting to compare to the 690/701 which are pretty much the only other dual sports available at the moment.

[@ShonkyProductions]

Hi LBD, thanks for your comments. I will defiantly do some follow up videos on the mods with general trail riding / dual sport in mind. As for the costs, I'll keep a tally and include it in that video.

Hi there, love the vids! I’ve been adding mods to my rally to rips around up here in Coffs. I did the full moto x and 550 ecu and air box lid that transformed the bike! So mush better I also had the cbr velocity stack and fitted it a few weeks after, I’ve got mad vibrations no on the bike now, did you get that or have to adjust the fit a few times? Wondering if I need to enlarge top air box hole and fit dna filter to match larger stack now. Any advice appreciated. Also did you change motox end can because it was too loud?

[@ShonkyProductions]

Where in the rev range are you getting the vibrations? Yes, I modified the exhaust baffle to make it quieter. Also, there are several versions of the Moto-X exhaust, I have the longest muffler that make to keep the noise down.

[@stuartrutherford9583]

@@ShonkyProductions hi, was getting vibs between 6 & 8k. So much so that it gave me a bad earth on the battery. I’d just fitted a lithium one when adding the stack so possibly was lose…maybe. I have since removed the 3 bolts holding the battery tray to the air box and it running great now. Same as stock vibration. Battery is so much lighter so the two tray bolts to the frame is fine I feel. I suspect the stack needs twisting a bit more for true alignment with throttle body….but loving getting out there to much to strip,it down again. I have the v3 moto x, feeling it’s a tad to loud so might have to fine a db solution also. Run’s crappy with motox spark arrestor or db killer.

I'm wondering if you watched Jake the Garden Snake do very similar mods to his 300 with questionable performance improvements? I sure hope yours turns out better than his.

I don't think Jake had the 550performance ECU. You need the ignition modified to make more power/torque, not just fuel. I don't think he changed the intake manifold either. Just adding the cams will not help if you haven't changed the restrictive intake manifold.

Luckily, allowing the rear axle to slip forward to it's minimum travel, this was just enough to get the sprocket in without removing the rear wheel axle. I checked and got a reference of the original chain slack ( brand new bike ) before fitting and replicated that after the new sprocket was in place.
