- Installing this oversized exhaust valve cover for 2023-2024 TBI 250 or 300 bike is an easy way to gain the bottom and midrange power you want, along with crisper throttle response. Fits all 2023-2024 250 and 300 TBI bikes. No refueling required. Better and safer than a high compression head, of adding bottom end. It's only $59.95 on pinitracing.com and includes a new gasket.

I want to give a shout-out for this product. I put mine on my 2023 TX300 and wow, the improvement in throttle response and mid-power lug ability is amazing. It also seems to have cleared up the throttle bobble. I'm excited to put on a new header pipe to get the full experience since my current pipe is really badly smashed.
Appreciate the good report. I will say the pro circuit pipe works the best to compliment this part. The pc pipe is the best overall anyhow. Better mid range than stock. FMF just like stock and scalvini was a loss, no matter what the situation. Bills has a bit more over rev. I test A LOT of stuff
The more I see about these tbi engines the more I keep seeing 250/300 stuff. I have a 150 tbi and would love to see what you think of that engine if you get your hands on one.
More great information!!!
On the tbi bikes running lean on the high end, what symptoms did you notice.? I'll be ordering the rail and line kit
Power just seems like it falls of and doesn't keep pulling. May hear some knocking. Thank you
I just order two for both my 24 300s. I'll try it on my regular rider first and report back. I ride at 9K elevation in Colorado and run a high compression head and BR8EIX plug.
Regarding TSP, I will never purchase anything from that company. I can share details offline but suffice to say, their customer support is worse than just lacking, it's non-existent. Caveat Emptor!
This sounds great!
I have a 2024 tx300 with a medium compression head. Would adding this larger cover and the reeds that also sell help add some bottom end and possibly midrange ?
Thanks. Don't add the reeds, but the reed strips and the over. Then it's a bottom to mid gain
Just a thought, a $29.99 spacer and gaskets for the stock cover.
It's a good idea and that was originally the plan. The gaskets were expensive at the time though and between 2 gaskets, longer bolts and a plat that had to be flat, it was $30 just to make it all. Plus this way it looks trick with that anodize color and the business gets signage
I think you should look into producing a clutch weight for the betas, they are now using a diaphragm style like ktm.
Their flywheel ignition configuration does not allow for a flywheel weight, so no one makes one.
You'd be the only option.
Ok. Hi Dave. Which model. A lot of people ask about these
@@pinitracingdevelopment5445 the 300rx model could use it or 250/300rr
I just received mine. Can I use the stock bolts? Because I did not receive any other bolts with the cover.
Yes. Stock bolts. And thanks
Would be awesome to see the difference on your dyno.. I'm on the bubble for this though, I want one but $60 and might just be "SO" maybe you could include one of those funny snake oil stickers with these :) ...
Ok, so quick update only a few minutes after seeing this and considering it I thought WTH, I'll order one and check it out. So I'll report back on what I experience!
It doesn't show anything on the dyno. The exhaust valve shuts the chamber area off as it opens. It only affects when the valve is closed. To hard to measure things at low openings and which low opening right? You have 50 different settings for percentage of throttle and 40% is totally different that 38%. You'll dig it.
Is something like this applicable to the TPI bikes?
No. Different set up on those bikes
You say this is very noticeable for the 250sx? I want just a bit more pop right off the bottom. I have a TSP order through Southbay but I got an email saying “no longer than 4 week delay” :(. TSP is claiming very noticeable extra smooth power to help with clutch pops off the bottom etc. If you feels yours does the same I might tell Southbay to cancel and refund. I didn’t like dealing with TSP when I was using my ERM device on my TE150i. Whenever possible I’d also like to deal with US makers anyway.
The internal size of this one, and that one are he same, even though the shapes are different. This means they will have the same result. So for half the price you can have in a few days and will have the same result. I have to say though, that the reed strips we have, are a $ 200 improvement for only $20. So get both and that's a good gain for less than $100
@@ktmhusky your video says I have to change the reeds pretty often tho
@@davidbeauvais1364 The reed strips and reeds are different parts. The strips replace the stock plastic reed stops and let the reeds open easier for better bottom and mid. But yes, reeds wear faster than people think. People change tires all the time and even top ends, but never reeds.
@@ktmhusky How long are the reed strips going to last
Okay folks. I just had to add my $0.02 in here now that I have received this power valve cover and put it to the test up in the high mountains of Utah. To be honest I can't tell a single bit of difference so I guess my opinion would be that it's kind of a waste of money. Now. Maybe some other people will feel differently about it and have a different experience but on my brand new 2024 tx300 this device does absolutely nothing.
Hey you can send it back and get your money back if you want. I don't anyone to feel like they were ripped off. Others say it's a bit too much midrange, but I'm pretty sure they are at lower elevations. What's your name

Ya I'd send it back if you're good with that.
@@flingndirt_UT Yes of course
Interesting because I had a lot of luck. I will say it's not worth the $130 TSP wants for it, but my friends bought 3 more for the $60, after trying it on my 24 300 XCW. I bet slavens would have never been quick to stand behind something he sold for $130. Looks like everyone wins
Significant difference for my 2024 ktm 300 xc, I wasn't expecting much .Love it when an add on is better than advertised
TSP clone? I heard basically the same thing from them days ago
They came out within 2 days of each other it seems. Considering the fact that no one could make one and have anodized and laser etched within 2 days, it was just a fluke we were thinking the same way. At least we validate each other on this thing
@@pinitracingdevelopment5445 HaHa True that.
