CRF250L initial review

[NordieBoy]

If you start loosing traction with those tyres,16f/14-16r psi would help no end.

yeah, next time I do the 42nd I will have rimlocks front / rear, once it starts getting wet on this track I imagine the stock tires @ 22psi would be, well, challenging!

I'd only go for rimlocks in the rear.

Next weekend s mission will be the Maihihi trail ride (with MotoZ Tractionators!) or if I can find the extra cash......head down to Waiuru for the Tussock two day ride....

Just as I got out on the Kapoors side I passed some dude on a Yamaha XTZ 660 going in; given the choice I would stick with my CRF on a tight track like this! Having said that, I do want to take my 2007 KLR650 through...

I took my 250kg GS through there a few times, usually road pressures on legal knobblies like E-09. It's good fun. In winter the streams can get up to mid thigh height before they are pretty difficult to cross.

Have a look at this trip, particularly the stream crossing from about 2'10". Excuse the quality, it was filmed using a first generation GoPro which was picking up interference from the motor.

Ive done this a few times on my MTB. Never thought of doing it on a trail bike. Having a car at both ends may be a pain though.

Brilliant video, certainly more water when you guys did it! I notice you started on the kapoors side, when I head back in later this winter I will still come from the Owhango side so as to do more uphill on the clay than downhill!

My 350 only goes to 8,300rpm.

I've ridden one - thought the timing chain was going to head north and take out the "family jewels" - so I was pulling 8300 RPM

Just installed the EJK fuel tuner, super easy to install. Only additional mods is I've cut back the snorkel so there is only the external part and removed the airfilter backfire screen. Holy crap I've got a new bike! This is the best mod you can do (asides from the 13t front sprocket) on the CRF250L. More power everywhere, overseas dyno reports show that with this mod I'm almost at the power of a WR, but with a lower center of gravity and better manners on the road. I took the CRF back up the gravel roads to Mt Pirongia and basically destroyed the stock rear tire, the new power is great. The bike was great beforehand and now it is awesome. Only waiting for radiator guard and bash plate now. Next rear tire is a slightly used T63 that's been sitting around. Can't wait to hit the 42nd Traverse again this weekend......

...and removed the airfilter backfire screen......

Um, pardon my ignorance but what have you done to stop the air filter catching fire now the screen's out?
Did you get a flame retarding air filter instead or something?

Good question! removing the backfire screen is a common mod on the CRF (once fuel tuner is installed) and (so far!) no reports of any negative or flaming incidents. Check out the "Best Dual Sport Bikes" website, that is where I got the idea from. Many other users have done the same thing with no issues other than improved airflow. To counter the painful thought of my bike catching fire, I've attached a photo from Mt. Pirongia looking down to Kawhia.

That's great news you are happy with your new mod, I don't mean to burst your bubble but if you believe your CRF250L stock 18hp has been increased to the same as a WR250R stock 30.7 hp with the addition of just a fuel tuner, you may want to cut down on your daytime drinking. An improvement it may be, but nearly doubling the hp? Not a shit show in hell

Not tying to be a prick, jus sayin

Dyno reports say no difference on the DR.

My screen has been out for more than 100,000km now.

Do I read this correct: you checked whether removing the backfire screen made a difference and it didn't? Mind you, Suzuki screens could be less restrictive than Honda's, the CRF backfire screen was like a whole other airfilter. I've contacted EJK and will report back on their opinions as to whether airbox & screen mods help/harm/do nothing to assist the EJK tuner. It certainly "felt" better with the screen removed, but my butt has not officially qualified as a dyno.....yet!

Holy crap!! didn't realize that the WR's were that powerful! My bad...but check out Rick Ramseys comparison....

Doesn't mean much as I'll never buy a WR, but certainly interesting reading...
