Yes, with ERM it's easy to make fueling adjustments and then test to see how it feels. If it's a rich stutter try leaning out the setting at low rpm and test it...

IMO the best performing carb for off-road is a Keihin PWK 38 Air Striker fitted with a STIC metering block. It's what I use on my 2017 KTM 300EXC. Strong and responsive power from bottom to top. Yes, unfortunately it's not a cheap option. tokyooffroad.com/product/stic-keihin-pwk-38mm-air-striker-short-kit/

@@TokyoOffroad i will have to go stock keihin, those metering rods very pricy in SA, im assuming 38mm airstriker better than the 36mm, thanks for your thoughts

@@user-ud7fo8no8l - Regarding stock Keihin PWK Air Strikers the 36mm will have better bottom end and the 38mm will have better mid and top end. Add a STIC metering block and the 38mm will have similar bottom end to the 36mm and still be stronger mid through top.

@@TokyoOffroad hi, i see your link for the carb kit, am i right in thinking, its everything i need, i see plug and play, is having this shipped to SA not a problem

@@user-ud7fo8no8l - Yes, I jet the kits with a baseline setting suited for the customer's bike. Shipping to SA is no problem by UPS. The shipping cost is calculated automatically on checkout. Thanks for your interest.

@@danielbrown2310 - I’m located in Japan. Yes, I can fit kits, but my recommendation is to use someone local to you.

@TokyoOffroad Ahhh. Well I definitely didn't realise you were over there lol. I'll try and find someone I'm the UK.

With TPI the fuel injectors are located after the crankcase, at the transfer ports. The majority of the fuel will only go to the top part of the cylinder (occupy the space between the top of the piston and cylinder/head). The oil is injected at the throttle body. Running premix through the oil pump would result in the crank bearings and lower part of the piston/cylinder not get much oil (as the oil pump only injects a small amount about 1/100 the volume injected through the fuel injectors). I wouldn't recommend doing so. If you want to use premix, relocate the injectors to the reed valve block and delete the oil injection. This way the full volume of premix will flow through the crankcases, just like a carb, or TBI bike.

Sometimes they are a tight fit and don’t pull easily off by hand. If you have a gear puller use that and it’ll pop off very easily

@@TokyoOffroad if my seal doesnt have any visible damage could it still be bad? My bike has all the symptoms - oil on my swing arm, super smokey, boggy, low oil levels etc

@@TokyoOffroadthat worked so well thank you

@@TokyoOffroadmy distance collar is just as stubborn coming out - any advice for that?

Yes, they are in short supply. I just received some stock of Keihin 38 PWK Air Striker short body carbs and have updated the availability on the webpage here (note: I only sell modified carbs which include a STIC Metering block): tokyooffroad.com/product/stic-keihin-pwk-38mm-air-striker-short-kit/

Yes, my stock 2024 300 EXC TBI had very poor fuel economy (worse than a carb bike). But with the TSP map, fuel economy is very reasonable and similar to a TPI. Bike runs really well now with the TSP mods (map, medium compression head and oversized PV cover).

@@TokyoOffroad My 2020 150 powers well on 80% fuel. You should read my Crank Case Injection build thread on KTM forum. I cant post a link here. Quite eye opening how wrong KTM got it.

I'm using 13/50 gearing. Works well for my riding.

I can't comment about the Pinit Racing version. Regarding the TSP PV cover, as I showed in the video they have done dyno testing and the difference is clear, so definitely not snake oil. The TSP tune with medium comp head were night and day difference compared to stock.

Yes I have cleaned and checked all connections

Are you asking about draining the 2-stroke oil from the tank and how to clean/replace the oil screen? It's covered in the KTM Repair Manual in the Lubrication Section. The method is to remove the throttle body, remove the oil pump, drain oil from the tank, remove the rubber boot on the bottom of the oil tank and the oil screen will come out of the bottom of the tank.

Did you find the issue. It must be an electrical issue. Check the wiring and connector. If the oil pump isn't working you should see a blink code on the dash display

Thanks for your interest. Due to requests I do make and sell the brass CCPS couplers on the Tokyo Offroad webshop here: tokyooffroad.com/product/ccpscoupler/ I also offer modified plastic sensor trays which accept the brass coupler and will have new stock of the 2020-23 trays next week

The spoke nipples can still turn OK even if Tubliss rim tape has been applied. I haven't found it to be a problem...

@@TokyoOffroad Thanks for such a quick answer! Been riding a 2022 500 EXC-F and just picked up a 2024 300 EXC-W. Filling my shopping cart! Wife may move from her 2021 FE350s if I can find a way to soften it up a bit for her. Suspension is a bit stiff to me. FYI, just installed MXTech Lucky cartidges in my 500 and National Shock, unbelievable!

@@MarkSpencerAZ Congratulations with the new bike!

Pleased to hear that you found it useful

Yes, the XP1 kt work great for rocks. Compared to stock the fork will feel plusher (as it keeps it higher in the stroke) and more stable. It's a good choice for technical riding including hard enduro.

Personally I'm not a fan of using gasoline to clean foam air filters as I found it hardens the foam and breaks the filter down, significantly reducing the life of the filter. Besides which kerosene is a lot cheaper than gasoline where I am. And engine oil doesn't tack up, drips and makes a big mess.

Yes, for sure. The upper lower s do have protection stickers installed so they help protect against that. In the past I have taped the edges of the guards to prevent dirt ingress and that works well. But the guards are easy to remove and install so taking them off for washing is a good idea.

Yes, for sure. In the past I have taped round the guards to prevent dirt ingress, but these are easy to remove and reinstall so removing to wash makes sense. I do have protection decals under the upper lower guards which helps too.

15W/50 oil is specified in the manual and is what I always use.

Last week I had a problem on the left side. The radiator bent back in a crash, hit the left side PV cover, squashed the lower radiator hose connection and started leaking. I took the radiator off and was able to shape the connection so that it was round enough not to leak when the hose was attached. As such I'm looking for some radiator guard which offer better bend back protection...

Yes, you could do that. Or you could carry a small container of 2T oil in your backpack.

No, the ride location is in Gunma. If you’re interested in joining a ride please send me a message here: tokyooffroad.com/contact/

@@TokyoOffroad ok will do.

No, sealant on the threads is neither recommended, or required. The torque specification in the KTM manual states 6Nm with no threadlock.

For MX, as you're typically riding on the pipe at higher rpm, I wouldn't expect there to be a big benefit. Lugging the bike at low speed on steep low traction dirt and rocks is where the low rpm torque and power is really important.

Noticed a big price difference between this and the and Pinit Racing version, over a $100 cheaper for the Pinit.

@@racesla Yes that is true.. Which is why I bought the PinIT racing one but hard to say which is more effective.

@@TokyoOffroad Well there are those pesky rutted MX turns that I'd like to avoid using 2nd gear if possible. My 300SX w/PC Works pipe according to Pinit, may be a bit much into the mid-range.

He’s had the head and tune for several months and has reviewed them in previous videos.

Thanks for your feedback. My intention is not to mislead anyone regarding what I'm testing and I did include details of the engine mods (TSP Map and medium compression head) and setting (green map) in the the video. To help avoid any confusion I just updated the video title to "Two Stroke Performance Oversized PV Cover- Install and Ride Impressions (with TSP Power kit)". I also added some more detail to the description of the video regarding the mods on my bike: "Testing was performed using the TSP Power Kit (medium compression head and TSP Map 3BE-24-J) and Green map, with FMF Fatty pipe and Moto Tassinari VForce4X Reed Valve." Hope it's clearer now.

a whole lot of ktm/husky riders have an aftermarket exhaust, race head and tuned ecu and/or maps. a lot of ktm/husky riders mostly chase gains due to the emissions and possibility of much more power with it with the dreaded emissions. either way power delivery will still be different in any application and will improve low to mid range by some margin.

Acting like you know more than this guys tells us all we need to know about you.

No, the cover only fits TBI 250/300 bikes (currently 23&24 year model)

This is not possible because on previous generation engines there is no exhaust chamber under the power valve cover

I think S3 make one for those years
