    Thanks guys! I will give it a try today with an impact and the correct bit, luckily I didn't damage the heads.

    Yup...Balkan Boy is correct...they are not EXACTLY phillips...and the "+" is more shallow....for quick and dirty, you can grind (file) off the tip of the phillips to make sure you have a good bite in the +.....but trying a couple of smacks won't hurt...because if the bond is broken, it'll be loose enough that you don't bugger the +

    Central Hobbies sells a nice set of 4 JIS screwdrivers for $17.99. I've had my set for 18 months and use it on all the screws that have a JIS dot on the head - they work great.

    Japanese Industrial Standard Screwdriver Set (4), Item #:CHMJSDS
    Unit price:$17.99 USD (Plus $8 shipping).

    Got it off guys, thanks for the advice. I couldnt find JIS bits locally so I tried my luck with a regular phillips head and an impact gun, worked like a charm. :freaky

    How would you compare the FMF pipe's sound compared to the stock system? I've just heard a clip or two on the internet and it's hard to tell how loud it really is. I would like a new exhaust on mine but I don't want something that is obnoxiously loud to others.

    I would say this video is accurate of the sound, I did the muffler and header at the same time so i can't tell you how it would sound with the muffler alone.

    At cruising speeds, it isn't loud (actually quite nice) but definitely gets loud as you crank the throttle. I should have used my dB meter to take measurements... sorry!

    I'll try taking a video on Friday with audio gain control turned off (so that it doesnt try to amplify the sound).

    Hey guys, I haven't logged on here in years since I sold my KLR 650. I've been looking at dual sport bikes for a couple months. I thought I wanted a Kawasaki KLX 250 with the 17" wheels with the on-off road tires on it. Saw one on ebay and it looked cool. Then I ran across the Honda . I've had a few different bikes in the last 10 years, always seem to buy what my friends were riding. Older guys, cruisers, younger guys, rockets, but all my early years ( 6-18 yrs) I rode a SL-175 then a MR 250 Honda. Went with my dad when I turned 16 to buy a 1980 Honda XL250, but he would not let me buy it. Now I'm 48 and I can buy it if I want. So, I went to my local Honda dealer and the owner used to work for me when he was a kid. Anyway, he had 1 left out of 4 he ordered. i asked why he orderd so few and he said the dealers were afraid the bikes would be a flop, boy was he wrong. He said dealers are calling from all over the east coast offering him $500 over his cost to let them have it. I didn't ask how long it takes to get more or if he had more on the way. I really just stopped to look at one in person and as it turned out, the owner wants some work done at his house and early next year we are going to trade a bike for particle payment against my labor.He says Honda offers him an end of year deal where he gets credit against Hondas like a bonus. He said he will get me a bike as part of his bonus, maybe even a white one. But I like the red a lot. I hope you guys keep working on your bikes making them better so when I get mine all the bugs will be worked out.

    OK, thanks! A video would be great if you can make one. I'm sure other's would appreciate it also.

    Has anyone come across wider mirrors than the stock ones? I wear a size 56 jacket and the mirrors are almost totally blocked when I am riding. Thanks, Bill C

    From you pics I can see that you disassembled the muffler, but what mods did you actually make to it? Maybe it'll be obvious once I take mine apart and compare it to your photo but so far I am not seeing what your mod was. If you took the screen off, then cut the pipe shorter and put the screen back on, how much did you cut off? Any details would be great as I can't afford an aftermarket pipe plus I find them too loud. I would prefer to open this one up a bit without getting carried away.

    Also, I'd like to get one of those Dobeck FI controllers but their website doesn't even list them. Can anyone recommend the cheapest place to get them and hopefully a place that'll ship to Thailand? Thanks!

    The Honda spark arrestor hasn't changed much since the early 80's. The "arrestor" is the fine mesh screen that you can see in Dirt699's second picture. The exhaust flows thru the screen, thru "windows" cut in the tube, then out the end. The version of Honda spark arrestor I am most familiar with is the Honda XR400R. The earliest model...like my '96 had a tube similar to the CRF, with very large windows (much bigger than the CRF). Then to quiet it more, there was a "pea shooter" stuffed into the tube after the "windows". Later models had smaller windows, and more restrictive "pea shooters" to meet stricter (lower dB) sound ratings. The size of the windows, the restriction of the mesh size, and the peashooter restriction can make the exhaust louder or quieter, and power is inversely proportional to restriction. The point I am getting to is, theoretically, redesigning the spark arrestor insert with bigger windows, and increasing the inside diameter of the tube may be a cheaper alternative to a whole new muffler to improve power. I redesigned the spark arrestor and peashooter on my XR400, and the power increase was very impressive, and inexpensive. Of course, there are other reasons to eliminate the ENTIRE CRF muffler because it is HEAVY, and there is the additional restriction of the catalyst buried in the muffler. Folks who cut a window in the Yamaha WR250R muffler to remove the catalyst report very significant increase in power. Finally, Rocky Mt ATV sells their Lexx slip on mufflers for many models, and is comparatively inexpensive ($199). It is a very popular exhaust for the cost conscious KLR650 owners. Unfortunately, there is nothing for the CRF...yet. So, bottom line is there may be alternatives to spending nearly $1K on an obnoxiously loud CRF aftermarket muffler.
