Installed new pipe on my boys xr80

Recommended Posts

I put an fmf powercore 4 pipe on the little 80, and holly smokes...it's like a different bike! More power from top to bottom, and it sounds awesome! My boy is now a baby thumper :) i was just excited about this, and thought i'd share.

The bog is normal for a 4 stroke. They don't like "quick twist to the throttle", especially from an idle. The engine has a had time dealing with the large amounts of air from the quick snap of the throttle.

Sarge you don't have that CRF or XR over there in Iraq with you do you? Just kidding!

I'm thinking about doing the same thing for my boy's xr80. Where did you end out on the jetting?

Sorry for taking so long with a reply.

The bike is snappier all the way through, there is a slight bog from idle, but i think that going from the stock 95 main jet to a 100 will take care of that, i haven't done this yet, as soon as i do i'll report what happens.

I've been searching for some more power for my son's crf80.. Who has the best price on that pipe right now ?

Does anything that fits the 100 fit the 80 of the same year model?

Rockymtn has it cheaper, but it says silencer? Not sure if they mean complete pipe or not ?

Mine is the complete set-up, header, and tail pipe.

      A while back I picked up a '95 XR250R swingarm that I plan on installing on my '90 XR200R in the near future, to save a little weight and have rear disk brakes. 
      I missed out on a totally complete rear brake system for $75 a while back which sucks. I look on Ebay every now and then hoping to find a great deal on a complete or near complete setup but no luck lately.
      Is anyone aware if Honda used the same brake system that was used on the '90-'95 XR250R, on any other bikes? 
      If so, then I can expand my search. If not, then I'll just keep looking at 250 parts til I find the right setup for the right price.

      Has anybody purchased/used one of these Arrowhead IHA6017 cdi boxes??  I tried 2 different ones of these on a 1987 and 1994 XR200R, and the bikes won't even start.  Bikes just pop and backfire, had to put the old cdi's back on.  I noticed when I ordered the boxes they stated "advance ignition curves" in the specs.  The box is also much bigger than the stocker and won't fit in the rubber mount.  I didn't mess with moving around the timing to try and get these to work....I just sent them back.

      Recently picked up a 1987 xr200r in pretty good condition, all stock.  The carb was all gummed up and running real rich, and the previous owner removed the baffle and end cap from the exhaust, but left the air box top chute in place.  I cleaned up the carb and verified all stock jetting, needle position, air screw, etc.  Where we live the quieter the better for off-roading so I ordered a new baffle and end cap, but did ride the bike for a week before the parts arrived.  With the muffler parts out I had a brown plug and plenty of power throughout the entire throttle range.  Got the muffler parts, installed them and now the bike falls flat while climbing hills and gradually rolling on the throttle, I get a burble at low speed sometimes and I have a black sooty plug.  I'm kind of at a loss on this one.  I realize that the parts restricted the exhaust....but it's basically back to stock and I've had these bikes stock before and they ran fine.  Seeing as I have all stock jets and am getting a sooty plug, I'm wondering if electrics are weak?  I also tried adjusting the air screw in/out and moving the needle clip to position 2, either of the two made my problem worse.
      Any ideas?

      So the other day I notice that the rear shock spring on our 1994 xr200r had cracked and separated about 2 coils from the top.  No big I thought....just go on Ebay and pick something.  Well, after a few days of looking I can't find ANYTHING used or aftermarket!  The stock Honda spring #52401-KT0-691 is "no longer available".  Can anybody lead me in the right direction to get a replacement spring for this bike??
      Thanks in advance.

      I have a 1999 xr200r. I used to ride it like a champ than i stored it for a year getting it out once in a while to run. Than i took it out a couple days ago started it and it ran and died instantly. I cleaned out the carb put everything back together and still sane thing. You have to feather the throttle to keep it running. It also made a loud pop and it jerks you when you ride it. I changed the spark plug, cleaned the carb, and put new gas in the tank. Any ideas? Wanted to ride it this weekend...
