I believe I got screwed, cause I'm new to this.

So I've been looking for a bike for a few months, havnt ridden since I was a kid. I wanted a kx450f and have looked at a few on facebook MP and at a couple dealers, usually 2013-2018. Well last week i went to a local dealer and seen a great deal for a 2022 Kx450f with an hour meter saying 3 hours. The price was more than others I looked at but felt that it is so new it would be a safe bet, so I bought it. Well a buddy looked at it and told me it got alot more hours than that and has a vortex ecu swap. Also I didn't notice but was missing the factory skid plates and a couple other brackets. Also has 2019 plastics. My question is what should i do? Would the dealer have know they were lieing to me about hours and condition?

Can for helmet/handlebar

I’m looking for a good camera for my 13yo to either mount to his helmet or handle bar. I’m so not technical haha, so I’m hoping people have suggestions. I’d like something that has audio, as he had been verbally assaulted many times while out riding. And something that can maybe record continuously for several hours, it looks like GoPro’s only go for about 70 mins.

There’s been too many incidents of adults on back roads doing stupid shit to him. From cutting him off with their trucks, to trying to shove him off, videoing him, threatening him, cussing him out. Today was my last straw……

He was out riding with his 10yo brother and 12yo friend and a guy on the road pulled a gun on them, chambered a round and pointed it at my 10yo. We made a trooper report, the troopers made contact with the guy about 2-3 hours later, he consented to a body and truck search but they didn’t find the gun (which I’m assuming he had stashed back at his house by then) and of course they didn’t search his house. So we don’t have a case to press charges now. My boys are responsible and not doing anything reckless or damaging they are just out trying to enjoy the summer safely. But I am so worried about their safety now!!

Leaking gas tank yz125

If my tank was leaking through the bolts where the plastic attaches, would I be correct in thinking that as fuel evaporated, the oil ratio would increase (eg from 32:1 to 28:1)? Would I then also be correct in saying that this is a leaner condition with less fuel and more oil going into the crankcase?

Where can I drive my talaria without a license?

So ik thinking that you can go on trails that aren't made specifically for anything for example our local MTB trail is basically just a 3 minute downhill and 30 minute uphill I see a lot of dirtbikes hanging out there cuz that place isn't made for cars but cars can fit inside now that's just an example

My dudes, I recommend Fivemile Pass, in Utah.

Teeming with side-by-sides, but a rad spot nevertheless.

What’s your favorite 2 stroke oil?

Personally I think Castor 927 has the best smell to ever exist. What’s your favorite for smell, reliability, price, and whatever other factors play a role? What ratios do you usually run? Does your bike have a sweet spot or do you just go off what the manual says?

06 crf250r wont kick

I bought this bike only being able to bump start it and trying to figure out what the issue could be? It dont want to idle, the longest ive ever got it to idle was around 30 seconds before it dies. Looked at the idle screw to try and adjust and its broke. Im assuming this could be the reason for it not being able to be kicked started? Still a newb here so any input would be appreciated!

2008 CRF 150R Help

Hey everyone, I need some help with a 2008 150r. It starts fine first or second kick, seems to idle fine but will stall randomly sometimes. I’ve tried every clip on the needle, 38-50 pilot, 140-150 main, checked valves, timing, acc pump screw/o ring mod, etc. cannot get this thing to run correctly. The problem is about 30-70% through the throttle, once it’s past that it rips. I know these are finicky sometimes but I’m lost. Elevation is 500ft

My bike wobbles while leaning?

I just got a 2018 250fx with a rebuilt engine. I rode it on trails today and I noticed after a while, it started to wobble while I would turn or lean it so I could turn. What could be the issue causing that? Also while I’m here, any advice on getting it onto a 5 gallon bucket? We don’t have a kickstand yet, so that would help a ton.

1998 Rm250 hard to kick over

My dad bought a 1998 Rm250 3-4 weeks ago but since then we have fully taken the bike apart and cleaned it except for the engine. We don’t have any case splitters that’s why, but every time we try to start it up the minute I turn the gas on it dumps from the carb overflow even if it’s upright and the bikes off. Could that explain why the bike is hard to kick over? I believe it might be a float needle issue with the fuel dumping but I came here for answers. The front brake also is kinda locking up so when you move it you hear grinding from the brake.

Valve clearance on a 2008 Crf450

The manual for this models claims the clearances to be (0.011 +- 0.001) for exhaust and (0.006 +- 0.001) for intake . I just measured mine in TDC and got (0.012) for both exhaust and ( 0.003 L AND 0.006 R). Just a bit confused how the left intake clearance could be way less than spec since I was told they always increase in clearance not decrease.

Could that be the reason my bike won’t start anymore and feels like it lost compression when trying to kick start it. Would i need to re-shim all of them or just the left intake one?

Oh wise and knowledgeable Dirt Bike riders of Reddit, I need your advice?

My son’s 2021 Huskie TC 85 clutch is making noise, took out the basket and smoothed the contact points and replaced the clutch pack discs and spring but still making noise. Inspected everything while it was apart and didn’t really see anything out of the ordinary. Sounds like basket or something is rattling but i double checked the torque specs and all. Any ideas what I missed or what’s causing it? Maybe I need to tear it back down and go deeper?

Brand new KTM 500 threw cam chain and destroyed the engine, dealer says if it needs a new engine it could be months. What can I do?

Hey guys, just got out today for the first time on my KTM 500. After just 27 miles it appears to have thrown its cam chain, blowing a hole in the top of the motor as if someone took a chainsaw to it.

Called the dealer and they said if it needs a new engine (which they believe it will) it could take months before it’s back together. Needless to say being without a bike that I just bought a week ago for months at the start of summer is pretty infuriating.

Does anyone know what I can do, or what buttons I can push, to resolve this better than that? It seems pretty shitty that they can pull a move like that.

2stroke Bike stays high revs after closed throttle

New to dirtbiking so forgive my ignorance.

I have a 2018 Husqvarna TE300, bought it used with 94hrs on it. Taken it out 3 times now and it runs well. But I noticed in the past two rides, When the bike is warmed up and I've been riding for 30+ mins, I'll let off the throttle/close it and the bike will continue to rev/build. It doesn't last long, maybe 30 seconds and then goes away for a while and might return again during my ride (2-3hrs)

Is it possible that since this only occurs when the bike has been ridden for a while, there is expansion on a seal somewhere causing an air leak on a seal somewhere? Where would you start troubleshooting?
