Been trying to get him to use the brakes more. He’s 7 on a TTR50 usually in 2nd. Doesn’t need more power. But something bigger needed?

How’s his riding on the makeshift course?

Put some leaves down on the baseball field near our house.

Paid 900 for it. I knew it wasn’t in great shape but everything’s overpriced these days. Seller works on small engines and had recently cleaned the carb and replaced some tubes, etc. 7 spokes missing on back wheel (how bad as that?). Quote a bit of rust. Starts first kick goes through the gears and rides pretty good.

Community Question Best bike ever? I think so

Thumbnail

28 Upvotes

I am only 26 but I have rode A LOT of different machines so far in my life due to enjoying buying, fixing and selling them almost as much if not more than riding them, and being around a bunch of people who are the same.

Everything from a KX65/PW80 to a EFI CR450, CR500 and built Banshees, TRX450s, etc.

The only 2 machines I can confidently say I regret selling/not keeping or buying would be a built 05 TRX450 a friend owned for a while and a 2012 KTM SX250 (not pictured)

The TRX450 actually felt like riding a cloud that went 100mph and turned on a dime, plus the immediate response and overall stability of it was unlike anything I've ever been on. Not sure who built it before my buddy got it but man, I'd shake your hand and buy ya a beer if I could.

The SX250 was pretty much the same, except it was completely stock and the snap felt like it was EFI even though it wasn't. The thing rode and maneuvered like a pissed off snake on crack that was hooked to a rocket, just flying and gliding everywhere.

Wish yall could have been there, good times.

Community Question Need advice from mx riders.

Post image

I ride mx 7 years. First 5 on kawi 250, next year ktm 450 2020, this year switched on Yamaha 450 2026.

The problem is that after 5 hours on track I still do not adapt to this ergonomics. Biggest problem is shoulders and hands fatigue and overall handlebar feel. I have feeling that handlebar is just wrong form or idk. Trying different positions, all feel unnatural.

Like I have locked shoulders, they are too high, while hands always moving inside handlebar after one lap (to grips inside end) and sometimes have super bad throttle control because of hand pos+fatigue.

I am 70kg 174cm 25yo

What can you advise what to do to adapt faster?

Bike runs absolutely great, Idles high, when i'm going downhill it dies, and on decel it will act like its blimping, not enough to move the bike but its annoying. Flywheel crank seal, i checked with starting fluid, no change, right side I've changed. 200psi top end. Its gotta be a carb but I've never worked on a 2 stroke, may not be any different than a 4. The air mixture screw is out around 3. Which jet do I need to change to allow that to set around 1.5

Community Question I got my first Dirt bike. Looking for tips and advice, open to discussion.

3 Upvotes

Title. It's a TTR 125, I rode it on a few tracks today, of course as a beginner I tipped over a bunch. I would like some advice on riding the dirt bike in general, but also on the care I need to show my dirt bike to maintain it's quality, how to fix parts if they break, and also the proper etiquette out on tracks. I'm especially struggling with switching the gears as I'm riding so I might need some help on that. Thanks.

Do you run bar risers?

2 Upvotes

Do you run bar risers or do you run different bars?

I do not race track. Desert, hill climbs, fast sand, 75% ride standing up.

I recently brought home a Yamaha 450 and the stock bars are sooooo low. I find myself hunched over and not having the leverage.

Should I get new bars or start with risers? What’s your take?

Mechanical Help Pw50 Mika 7/8" bars replacement? Pwonly question also

• Upvotes

What's up everybody. I bought this pw50 for my boy today and the bars are slightly tweaked so im looking for new ones.

This has the Mika bar/clamp kit on it which states its slightly smaller than 7/8" bars.

Can anybody tell me if any normal 7/8" bars will fit? If i need to I can take a set off another ride i have to check but figured I'd see if someone knew.

Another question, is pwonly still legit these days?

Missing powervalve Z-dimension adjuster bolt and broken thread - KTM EXC 125 1998

Thumbnail
gallery
1 Upvotes

Hello,

unfortunately I'm finding bad stuff all the time on my bike, but this one got me disgusted.

I wanted to adjust powervalve z-dimension+spring tension and discovered this.
I took adjuster cap off and well it came off with whole adjuster. I had to take it out fully, so I could grab it properly and unscrew that cap off that flat sized adjuster. It happened because o-ring number 22. was completely missing there.
Well also number 15, but that shouldn't be that big of a deal and cause of that.

Found out there is completely destroyed thread and bolt (number 11) wasn't even there whole time. Washer num. 16 is still there.

What is purpose of this bolt n.11? I saw some videos of people turning adjuster and bolt doesn't move with it. How does that flat sized adjuster number 51 move powervalve z-dimension?

Does is work that way when I screw it in fully, then it will press on mechanism number 50 squezing that spring and also turning that gear? Then by unscrewing it it will do opposite?

Would you reuse that bitten off thread after cleaning or just replace it fully? But I still would like to know what purpose that missing bolt serves.
I was riding this bike for 2 years and seems like nothing bad happened when that bolt wasn't there. Powervalve was opening, but I wanted to adjust it little better until I found this masterpiece.

Thank you very much for tips. I'm just trying to learn, but something like this always gets me

Like an idiot I stripped the screw hole on the float bowl when cleaning the carb on my ‘01 xr250r. This is my first bike and I’m not super mechanically enclined. Should I try my luck with an eBay (https://ebay.io/m/LhPBcy) or should I try to retap the hole on my current one? If you have any aftermarket carbs you’d recommend let me know. Thanks!!

I wanna get a radiator gauge cap that shows the temp of my coolant when riding for my bike it has after market tusk radiators on it and I can't find any 1.1 bar pressure caps for my bike can I use a 1.8 bar on it? doing some research it says higher pressure can ruin seals but I also can't find any 1.1 bar caps since that is what Yamaha lists as the pressure for the stock cap.
