The CRF250L Owners thread

Is this your first FI bike?

Generally comments like this come from folks who have one for the first time, when you chop the throttle on FI bike there very little/no fuel going through the injector and the engine braking is more pronounced than with a carb'd bike, that also adds to why we get better MPG. All my bike are FI and feel similar to what your saying and I've seen lots of comments on the BMW forums from folks coming from a old school bike just like yours.
It's something you get used to, even depend on when coming to a stop.
I wouldn't disconnect the throttle return cable, but that's just me. If you think there's a real issue with it stalling then take it to the dealer and see what they have to say.

Good luck!

Dunno really.
Don't really care much either, we have a Bazzaz controller because I got it for free, I have no investment in the unit and don't owe Bazzaz anything.... I'm pretty impartial when it comes to them. If the results were anything different than what I feel I would say so, I have no problem speaking my mind. While enjoying the results we didn't buy this bike just to see what could be squeezed out of it, I'd have bought a Husky 310 if I though Nancy needed a higher performing bike, but the extra mid-range grunt from the controller is welcomed and obvious.

Maybe read up on the Bazzaz dynamometer to find answers, their's doesn't over inflate the results. Dyno results might seem like cold hard evidence when read online, but without knowing first hand about the dyno itself comparing their results to another is subjective, I know road racers who tune with the Bazzaz dynamometer because of it's accuracy compared to other ones, personally would I trust the ones that are most conservative if basing a purchase on numbers, but i'm not really the "tuner" type of rider and that's just speculation.

If folks with the EJK are happy, great, I would imagine the results are very similar as with what I feel with the Bazzaz, regardless of the varying numbers found on youtube.

LOST RIDER: It certainly all boils down to the altitude, ambient barometer, air temperature conditions and how the dynamometer operator & software corrects the power for these conditions. SAE (Society of Automotive Engineers) has a procedure for this...if everyone used this, there would be no pissing & moaning. BUT....most don't.

I was hoping you'd shed some more light on this since you are one of the few in here that has professional experience in the matter.
Methinks the only way to really have an accurate comparison between controllers, exhaust or other mods would be to have them all done on the same machine in the same conditions, or at least using the same standards you mentioned.
Bazzaz seems to be very conservative in their results and with their reputation I believe what they say based on my butt dyno. An obvious improvement in mid ranger performance, but it didn't magically transform the LRP into a race bike either.
Lots of marketing hype when it come to dynos online, especially by people trying to sell you something, I never got into serious tuning of bikes, I much prefer to ride them than tinker.

Any testing that's done to referenced standards still manages differ slightly when calibrations drift or the testers use different samples, if it's anything like loudspeaker testing. Which, as Lost Rider infers is more often than not used as a marketing tool rather than an honest comparison tool...

I sure found that to be true with aftermarket pipes on quads. Some of the bigger claims went with pipes that seemed nearly identical to ones with conservative claims. After i went through a few I found the stockers were often better at trail riding anyway -- and certainly less annoying when near private property boundaries.

Bottom line, as far as I'm concerned is "improvement in mid range" is what I wanna hear. I got the EJK....have yet to put it on...just piling on mileage to get to 600 and add it then. So far, mine has very nice torque...for a 250, and if I get some more as it breaks in, then with EJK, then maybe a touch with air filter & snorkel....I will be a real happy CRF owner!

I second this recommendation. Chad at Sprocket Center is a class act.

I have removed the backfire screen but yet to mod the snorkel.
Is the snorkel mod I hear about just cutting off the bottom inside the box?
Would it really make a diff to cut off 3" of snorkel? I could see if it changes direction of air flow but it doesn't.
What were bdsb's instructions for the airbox?.crf's only kit didn't come with any
Was also going to ask about th o2 sensor but I see on ejk's home site they recommend to leave it on as they did not note any dif on/off during their testing.

For some reason I cannot access BDSB's Honda section on their website. But, I removed the snorkel and unplugged my O2 sensor. I did feel a difference with the O2 sensor unplugged.

My mods are: EJK Programmer, FMF Q4 muffler, Megabomb Header, backfire screen removed, 13/43 Sprockets.

just ordered Q4. Very excite. Can't wait to dump this load that is my exhaust can onto the garage floor.

Who wants to loan me their fuel programmer hmmm??? In exchange, I will supply

After my mods it feels like a new bike. I enjoy it twice as much now.

That's what I did as well / all the same mods here besides the rear sprocket.Did you happen to notice any backfiring on deceleration? I may have to up my cruise fuel.

I do notice a little bit of backfiring but only when I'm decelerating.

Hang onto that exhaust..quick change and its ready for close to and in town stuff,trust me the q4 is loud enough to get some pretty dirty looks.
It's nice when close to homes to be so quiet. Zip,zip,zip. The q4 roars compared,in the middle of nowhere where no one will be bothered its awesome! that's my plan anyway.

Drop by I'll lend you my tuner. Lol

Cool, thanks
I'll probably just leave it for now,I kinda like it like that anyway,sounds a bit like one of my hd's with the screamin eagles if you twist your head and squint just right. Lol
I've got other stuff to mess with on it now after the bike and I slid 20' on our sides down a steep rocky slope after endowing a 6' vertical drop halfway down a long scary down hill....not so shiny anymoe

The Cycra ProBend CRM (Center Reach Mount) for 7/8 inch bars is what I went with. They fit on the stock and on the new Renthal bars.

Well I got to take my bike out for the first time this year . It felt good to get back in the saddle again especially since I just installed a seat concepts seat which is a nice upgrade over stock. I did a little mix of highway,town and dirt roads. However, on my way back home my bike started to stall and then surge. well about a mile later I found out why...no gas even though my gas gauge had one solid bar still. It must of gotten stuck, luckily I was only about 2 blocks down the highway from a gas station so I got some exercise today anyways. Some pics of the bike happy to see daylight again:

Awesome, I can't wait to save up enough to get the programmer and header. I'd like to put all of them on at once but my patience is non-permitting.

I was really hoping it wouldn't be so loud! :eek1

After spending too much time on YouTube it seemed like the quieter option.. I putt around town all day too, I guess we'll see how she blows.

Ventura eh? I live near Ojai/Oak View, swing on by sometime to compare bikes or shoot the shit. I can't ride but am home all the time right now...
We could do some testing for bikes with and without controllers maybe...

Moving to westlake village in a week so make it quick, or come out there too if it's closer.

Thank you for the help.
