The dirt bike thread!

BD, you know you can eliminate those "hourly rebuilds" if you just went with a 4-stroke Dual Sport....LOL! I read the WR250's have fuel injection and a 6th gear.

[breakdirt916]

Lol...yeah yeah I know

The issue with dirt bikes is they are high performance in the heavy duty environment...all require quite a bit of maintenance...so much so, that I look more at the cost of maintenance just as much as the cost of initial purchase.

Most KTM's (plated) will cost $2,500++, need more maintenance while riding, and close to the full value of the bike at each rebuild (albeit less often).

The low interval 4 strokes (drz400) are also pretty mellow on performance.

4 strokes can also be a bear to kick start hot.

4 strokes are also heavier.

So the YZ checks off a few bits off my list - light, top of the line performance, easy to start (hot or cold), simple to work on, and most importantly like, least expensive to rebuild!

Rode Perris yesterday...main trAck was gnarly, vet track was too small, couldn't figure out how to get into flat track

[Rogue]

I was just pulling your chain BD. 

I don't think there are any 4-stroke DS bikes with kick starts any more. 

[breakdirt916]

Ya...ahh the elicit magic button

Actually one of my favorite dual sport bikes is a Honda CRF230F LOL

Stiff suspension, high Center of gravity, and high power actually work against you in the really knarly stuff!

[Rogue]

I looked at the CRF250L....fit me perfectly, very nice bike. FI too. But....250cc is just that. Sustained 75-80 mph on a 250 just isn't very appealing to me for highway use.

[breakdirt916]

It's funny...those underpowered piggy heavy mini dual sports are stellar in foreign countries LOL

Just mailed my cylinder to Millennium Tech and talked to the tech...we are going to port the cylinder: lower it and finish it out so that it will make "more power everywhere".

Installing a WR transmission will best match the new/broader power output and, according to the tech will "be a nice little mod" and I would be very happy with the bike.

Can't wait!!!!

BD, I saw a video of someone with an Athena big bore kit on their WR250R. Claimed it had a top speed of 110 mph! It may have been a 310cc after mod.

I'm only at the free-flowing intake/exhaust with my DR. I might go with the high compression piston and camshaft mod someday soon. Right now it runs pretty sweet but I'm told it can be made into something even more special.

[breakdirt916]

LOL....I have seen those

I'm honestly a *little* cautious about super-ultra-biggest-overbore on a bike designed for a certain power output: trade off for wear and tear on other parts

I had an Eric Gorr 144 stroker on a '98 RM125...it was downright terrifying. Scarier than any 2 stroke 250 I've ever been on. Close to the violence and savage nature of a 450 MX bike. After I got used to riding the beast, everything else started to fail...It started with worn clutch basket and went as far as internal transmission bearings failed and shattered the crank case! I had to get new cases. I spent $3,500 repairing a bike I rode 10 times. Once re-built, it was scary fast, again...and then the next owner killed it within 4 rides.

As much as I'd like to bore out the 250, I'm going to stick to stock bore size and just change the way the power is delivered (via porting, reed cage upgrade (to boyesen Rad Valve, wide ratio transmission, and re-valved suspension). Hopefully I can go another 2 years...and this time I'll do the top end sooner, and go even longer 

Alternatively, I *do* have 2 motors...I was thinking of making one more street friendly/wide ratio, broad power. Then just build the 2nd one to slay and pillage cities 

It's actually kinda fun how "simple" the bikes are, and how sensitive they are to tuning. I can swap out jets for $20 at home and understand exactly how it works. Nothing like my F150 

[Rogue]

Slay & pillage cities...LOL! Do tell!  Speaking of cities I'd love to visit California City and explore there.

Have you seen Cycle Cruza's video? Check it out the dude is hilarious. He recently bought and modded a WR250R. He's kind of a noob and deeply opinionated and biased but fun to watch his urban shenanigans.

Yeah on engine mods, big bore/stroker kits will most definitely tax the engine's transmission, oiling, & cooling systems, not to mention your brakes will need upgrading. Realistically I probably will just put a longer duration camshaft on mine to take full advantage of the opened up intake and exhaust and stop there. Maybe...LOL! Yes these DS bikes are super easy to work on and dirt simple (no pun intended). My valve adjustments takes all of 20 minutes!

My first dirt memories are from CalCity as a kid at Galileo Hill camp ground lets set a date for a weekend its a resort in the middle of the desert with pool/bar nice rooms or you can camp near by, Riding is endless with trails perfect for beginners to the best riders, Ill do some research on this being my daughter Niki want to do one more trip this year maybe we can get a few together for a weekend before it gets hot.

[Rogue]

Pool, bar resort in CalCity? I'm in! But I'm riding to it. I'm currently fixing to install my GPS + radar detector mounts + power ports. I plan to ride this bad boy hooligan bike on long distance cruises to nowhere.

[FastMoto]

Just looked up Galileo Hill on Google Maps, looks interesting!!! So looks like it's a resort out in the middle of nowhere...and CalCity is out in the middle of nowhere already!!! My only dual sport at the moment is a large bore KTM so can't do too super tight/techy stuff, but can handle most terrains ok. Probably gonna be in the 90's+ real quick so the window is closing.

[breakdirt916]

I would be out...I mailed the cylinder for the YZ rebuild but still haven't pulled out the motor for the bottom end work...

We ben racing year round so long heat is not an issue , Arrive Friday evening to a air conditioned room have some drinks at the bar then suit up by 8am Saturday for a good 3 hour loop then back for lunch by the pool hang till 3 r so when it cools down then take another ride, Next morning rinse and repeat The wife my daughter and her bou are in also we love the place lets set a date!           

Couple pics from Thanksgiving 2004 we would camp a few miles away then take a granny ride with a chase truck to the park and picnic, Good times!

I'm in Arizona this weekend.  Memorial Weekend is out.  But I'm open after that.  I would rather stay in the hotel as I have no camping gear.  I'm also a dirt noob so I only plan to stay off any difficult terrain.

Below is recent video from Motogeo.  He went to visit CalCity.

 This is a fun one not only to race but spectate, Cant wait till Sunday!!

[Disco BoB]

anyone ride district 37?

[breakdirt916]

I do D37 dual sport events...not a desert racer tho

[Rd Todd]

 We were members n did a few races in 04 thru 07 but mostly just to attend the Mini Nationals at Barona oaks each year.
