I want to own a Dirt Bike sometime (It's on my "Things to do before I die" list :D ).

 

Do they have manual Clutches like the Yamaha Raptor I was disscussing in the ATV thread?

What's the difference between 125cc and 250cc?

About 125 cc's  :D

 

As far as what brand...I always liked KTM. Had a 125, and a 250.

 

What brand is entirely up to you.

 

People are just as opinionated about Yammies vs. Kawisakis vs. Honda vs. etc.... as they are about Chevy and F###.

 

Just ride a few, and see what you like....Then pick the one with your favorite color.

How much do you weigh?

 

A 125 cc will have a lot more power than you would think.  The problem is, the powerband is more eratic.  Say it has a 13k redline, it may not have any power below around 6k rpm, and then around 9k rpm, it takes off like a starving rotweiler after a cat.  No kidding, it feels like the handlebars are trying to run away from you.

 

The 250 will have more low end grunt, and probably be a funner (word?) pleasure ride.

Well, when talking about the 125cc vs the 250cc in a 2 stroke engine, thats a big difference.  All depends for your weight and riding ablility...the 125 is a good size to start out...the 250 is just a beast, too much to handle for a first bike.  I've seen guys buy the bigger 250 because they could and end up selling it for a 125.  Something you may want to consider are the 4 stroke versions of their bikes....MUCH smoother power (no insane powerband) and more lower end grunt.

 

As for the brand, as mentioned above...just ride 'em and pick the one you want.  I would suggest the Honda's though....my friends and I have had VERY good luck with them.... very strong & long lasting engines.   :D

125 2 stroke -or- 250 4 stroke

Ditto!

 

When you first ride it make sure you have plenty of flat, clear area to learn how the bike responds before you experiment.

 

I rode a friends Husqvarna (sp?) 250 years ago.  I started out on it and was disappointed with the power (all I had used was 2k-4k rpm).  So... I grabbed a handfull of throtle. :D Around 5k to 6k rpm, it was like twin turbos.  The front end came up and I had to wait until the power leveled off to losen my grip on the left handlebar and back off of the throtle.

Your story made me laugh.  One of my friends bought a YZ250 from a guy he worked with.  Well, he putted around a small field and bought it.  We went riding that weekend and I almost fell off my quad laughing the first time he nailed the throttle....looked like a wild horse trying to buck him off.  He ended up selling it for a thumper (4 stroke)

 

This is my analogy of engines for bikes, excluding power characteristics (ie powerbands)

 

125 2 stroke = 250 4 stroke

250 2 stroke = 450 4 stroke

 

Also keep in mind how complex each engine is to work on.  A 2 stroke motor will require more maintance than a 4 stroke (ie top end rebuilds) but they are MUCH easier to do.  There are no valves to mess with, no cams or rocker arms.  A 4 stroke can go much longer before a top end rebuild but is more complex (same as a normal car engine).  Just something to keep in the back of your mind...

      Disable AFM for $0: The M5 Method for 6-Speed Trucks

      By BlueV8 · Posted

      Disclosure: BlueV8 is a Supporting Vendor and sells plug-in AFM/DFM disablers.   Before you spend a dime with us — or with anyone — try the AFM disabler GM already built into your truck. It's the shifter, and it's free. ⏱ The 10-second version 🚫 Skip the M5 method if: Most of your miles are highway — M5 locks out 6th gear, so you cruise at higher RPM and burn more fuel You already know you'll forget — it only works if you do it every single drive Your lifters are already ticking — nothing that switches AFM off repairs existing damage You already run a tune or disabler — this would be doing the same job twice ✅ Worth trying if: You want AFM off today, for exactly $0 You want to test-drive V8-only life before buying anything Your driving is mostly town and short trips, where 6th gear barely matters Your truck is leased or under warranty and you won't touch the ECM — this is zero hardware, zero software 💡 The whole trick, in one paragraph Owners across GM forums keep reporting the same pattern: put the transmission in manual / range-select mode, pick M5 or lower, and AFM never activates — the truck stays in V8 the whole drive. Bump it up to M6 and V4 mode comes right back. Two of the cleaner threads on it are here and here. GM has never documented this behavior, so file it under "strong owner consensus," not gospel. The good news: it takes exactly one drive to verify on your own truck. Steps below. What "free" actually costs Effort, every drive. It's a routine, not a setting. Shift to M, tap up to 5, every time you get in. There is no set-and-forget here. 6th gear. When GM shipped trucks with AFM/DFM switched off during the 2021 chip shortage, its own estimate of the penalty was about 1 MPG — and those trucks kept every gear. In M5 you're also giving up overdrive, so expect the highway hit to be bigger than that. Patience. One Tahoe owner ran the L5 routine for two months, then got tired of it and bought a plug-in disabler — he had an extended warranty, so flashing a tune was off the table. That's not a knock on the method. That's just what month two feels like.   I put together the full instructions, limitations, and links to the original owner discussions here: https://www.bluev8.com/blogs/news/how-to-disable-afm-for-free-the-m5-method

      Half of you don't need an AFM disabler. Take 30 seconds to find out which half you're in

      By BlueV8 · Posted

      Disclosure: BlueV8 is a Supporting Vendor and we sell AFM/DFM disablers. We wrote this because not every GM owner actually needs one. In some cases, regular maintenance, towing use, an existing tune, or simply using M5 makes another device unnecessary.   ⏱ The 10-second version 🚫 Skip it if… You keep the oil full and change it every ~5,000 miles. Your risk is already low. You're happy shifting into M5 every drive. That disables AFM for free. Your truck tows heavy most days. AFM barely runs under load. You already run a tune or delete kit. Done is done. It's already ticking or misfiring. You need a mechanic, not a plug-in. ✅ Worth it if… You bought it used and the oil history is a mystery. Checking the dipstick is… not your hobby. (No judgment.) You're a long-term keeper with lots of easy highway miles — exactly when AFM runs most. The V4 drone and shudder drive you nuts. You're under warranty, so a tune is off the table.   The full article includes the supporting GM bulletins and owner reports: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler

      Metal shavings on dipstick and filter

      By PunchT37 · Posted

      It`s magnetic so it`s not main or rod bearings. I would pop off a valve cover or 2 and take a good look at the rocker arms. See if you can see if any needle bearings are coming apart.

      Metal shavings on dipstick and filter

      By Clay LeBlanc · Posted

      Hey yall.   I have a 2015 GMC Sierra 1500 5.3 2wd. I just did my own oil change (currently 132,000 miles) on the truck for the first time since I got it. It has always had routine maintenance done at the correct time. Never once had a check engine light, oil pressure light, or any light (except low fuel lol). Also never towed anything ever. It has been a daily driver for me.   I noticed the dipstick has metal shavings magnetized to the end of it. And even after wiping it and putting it back in like 12 times, it still pulls some out. The oil filter also has a good amount in it.  It has always ran perfect and still does. Never ever had a weird noise or knocking or ever ran rough. Almost too perfect lol. So this metal has really surprised me. I see some similar stories where people say this is normal wear, others say your engine is cooked. I know it’s hard to say for sure without seeing in person but just wanna see if anyone has had a similar experience at this mileage or any advice?   Thank you in advance.
