Worked better then advertised!

2009 Honda CRF-250X:
Install: The directions were not very good and a bit hard to follow. With a few minutes for rereading I was able to install the kit no problem. The parts looked just a shown and fit like a glove.

Difference: I'm 280 LPS of fat, I noticed a HUGE difference in the low range and torque. I have an after market FMF pipe and when coming down from higher RPM's I would get alot of back fire and sputtering. This mod made all that go away.

Easy install and used on Crf450x

Bought for 2012 with smog pump still on the bike. Follow directions and easy install. I also opened up the air box (cut to off, no side vent cuts), installed DJ jetting kit, flex fuel screen adjuster and a FM q pipe. The decel popping went away and gave the bike more power. The fuel screw did not seem to make a difference to jetting until I removed the smog pump. It was worth the cost as did not need to spend hours making a block off kit. I had it installed in about 30 minutes (but already had the bike apart to mod the airbox and put in a stiffer rear shock spring. Looks good too!

Worked great!

I have had this on for a few months now and had no issues. Installation was pretty simple and allowed me to shed a few pounds by getting rid of the emissions equipment.

Great product

Was debating on whether or not I needed this kit as it does not increase horsepower at all, but soon found out it was well worth it, makes working on the bike much easier and it gives it a much cleaner appearance. Instructions were great too

I read a lot about cost. the directions are straightforward and it goes right on. If you can not pay you can not afford to play. It is a great little product.

Big improvements for the price

I have done a number of upgrades to my CRF450X but exhaust aside, this is definitely one of the best performing upgrades I have done. Cost taken into account....the best by far.

Took me all of 10 minutes. Easy to follow instructions.

Okay, I get the whole "dress-up bling" thing and it does look good, but considering this is not CA legal....kind of like highlighting the sections of your test you cheated on for the teacher to find.

I purchased this for my 08 KLX450R and it worked great, the only part that didn't fit was the bolt to plug the intake (its to small). I just substituted an M6 bolt and was off and running.

A: Yes the emissions block-off kit comes with all of the necessary plugs, screws, and fittings. For more info and possibly instructions I would contact Applied at 1800-853-0555.
Q: Emissions Block Off
Over 4 years ago
After installing my Emissions Block Off Kit... Do I need to do anything to my jet system? I have a Honda 250x 2005

A: As long as your bike is currently jetted correctly, your 2005 CRF250X will not require re-jetting.

A: I found that it did lean the bike up a good bit, but adjusting the fuel mixture screw was enough for me. Note that I do NOT have stock jetting as I rejetted after exhaust.
