I don't know about the differences, but here is something I tried.

On the Q4 Hex, I removed the bolt that holds the spark arrestor/insert in place and tried to remove the assembly. It wouldn't budge. So I called FMF and asked the guy how do I get the spark arrestor out to clean it. He said, remove the bolt and pull the assembly out. I told him it wouldn't budge. He said that was unusual and didn't offer any more help.

I tried again. I put a small piece of metal on the lip of the end cap and used that as a base for levering an awl which was inserted into the screw hole. I tried to pry it out and it wouldn't budge. I tried everything I could think of and the most I got was a slight shift when I put my fat thumb in and tried side-to-side motion. But it still wouldn't come out.

Now I don't want to ride with the silencer core removed, I just wanted a look at it and the spark arrestor. So for now, I'm putting the bolt back in and mounting the muffler up tomorrow and riding.

Eventually, I may open the other end of the muffler and insert a smaller diameter core to reduce sound, but that's a ways off.

I like FMF products a lot. However, their "technical support" over the telephone is notoriously bad. I don't think their tech support via email is any better, but it can't be worse than their telephone "support."

If you're going to increase the travel by inches, it should increase the ground clearance / seat height by the same amount at full extension - unless you're putting in springs so stiff that the extra travel can never be used, but then that may not work well.
Landing from some air and going over the bars or breaking some ankle bones would not be fun.
Of course anyone can do what they want with their own bike, it's just another measurement to consider.
I was thinking about this too. But there would have to be a way to put bump stops in the forks. wouldn't there???? I think that the springs themselves would limit the travel, the further they get compressed the higher the rate becomes, on progressive rate springs anyway, but I guess that's only to a certain point. THis will take some thinking.

(I have a WR250R, not a Honda, but I think the FMF pipe stuff is the same.)
Didn't have an issue with removing the spark arrestor from mine. A small screwdriver inserted around the spark arrestor edge/exhaust pipe/edge usually works (probably with a hammer).

A Q4 pipe is pretty loud without the spark arrestor in the end. I ran mine a bit that way and most of the people on the street looked at you.
There is a difference in the Q4 and P4 internals. For a quiet exhaust (on the WRR), take a Q4 pipe and insert the 'quiet' spark arrestor from a P4. (Gotta bend the spark arrestor screen to make it fit in the Q4). Read the WR250R thread for the specifics.

WOW! no one lifted opinions or gave some tips on riding in? Please people , I thought this forum is place where like minded guys help and share with each other? Also if anyone could give me tips on opening the throttle end to fit hand guards it would be nice.


Thanks.

Like minded? You must be new here. There are as many opinions on breaking in as there are people here. A few dudes saying "ride it like you stole it" and a few saying "for the love of God baby it" isn't really gonna help you so there's little point going down that road.

Gals too don't forget. I use the search function to find information. Folks throughout the years have asked many of the same questions (for instance on breaking in there have been whole threads dedicated to that) search is your friend

I used a hack saw as suggested in the directions that came with mine.

Engine break-in discussions are in the same category as motor oil and chain lube discussions. People have a wide variety of opinions on these questions, and the differences are never resolved. Riders have success with greatly different engine break-in techniques, just as they have success with a wide variety of motor oils and chain lubricants. Pick any reasonable method/product you prefer, and you won't go wrong. Along that vein of reasoning, you certainly will not greatly err if you follow the manufacturer's recommendations.

I wondered that myself so I gave FMF a call. The guy said the Powercore would flow a bit more free and be louder for sure. the Q4 is better for riding on the road because it wasn't as loud.

That is what I was told.

Exactly, I bought my 250L, rode it for 20 miles then did the Shenandoah 500km. Which is a enduro event (not race). Rode it hard on the trails and on roads. It was happy with the high RPM's

in addition changing the oil out early in the motors life is key (say at 100miles or less). i do believe most all modern motors are also fired up once to test them from the factory so a new bike's motor has run already atleast once.

unless you've watched your bike come directly from the crate to assy and then you take it, many shops will start all news to confirm they indeed do run properly before a sale so that would be run #2. now the crf move fast but others bikes that don't might be started many times over after that at the dealership.
