Honda Need transmission help!!!!

Recommended Posts

I am trying to get transmission information from someone who knows what they are talking about. I have a TRX 250 X. Not the EX. 1st, 2nd, and 3rd work properly. The machine can NOT be shifted into 4th or 5th under power

of any kind. It will only shift into these gears after I let the machine roll for a bit then it will go in to them. After I do shift into the gears, it will go with no clutch slippage. Where would the problem be so I can fix this. I have to slow to about 50 mph to get 4th and about 60 to get fifth. Help me please! This machine tops out at 87 to 93 mph when working properly. Thanks in advance for any good advice that is given.:bonk:

That's an amazing little 250 you have there that will hit 93 mph. 95% of 450's can't hit 85!

He stated "mph"......quite and amazing feat for a little TRX250.

Actually, I don't think a TRX would hit 70 so yeah, I call bullshit!

Well judging by the lack of mechanical knowhow of the majority of people on here including a certain moderator I can understand the nay-saying. I was told the same thing about a 65 mph atc 185s but it has been confirmed.

And yes with proper gearing,piping, and jetting this is well within the capability of a "little" 250. If I decide to go with a larger than stock bore, which I may, Triple digits although low, are possible. Does a 250 Ninja go over 90? Again a little 250. I haven't said anything about the exacting specifications of the rebuild or the way I ported or polished the intake and exhaust ports. Nor anything about carb air and fuel flow, custom built exhaust to exacting specs, possibly expensive and extensive tire size and selection processes. So I guess if you want to say BS good for you. But until you spend the amount of time that I have on research and development keep your obviously inexperienced nose out of things. Everyone else, please feel free to offer any info you may have.

Why would you come here for help if the majority are lacking mechanical knowledge??/ Are you pulling in the clutch or shifting under power?? If you are properly using the clutch than I would suspect an internal transmission problem. Split the cases and inspect the trans.

Please help me put together a list of mods for my 400. I'm shooting for 148mph. Since it's about 40 percent larger than your 250 it should be about 40 percent faster, as well. Lousy comparison, huh? Kinda like comparing a Ninja street bike to an ATV, though.

Dude, a 250X couldn't reach 93mph if it fell from an airplane, literally. Give it up. You're not going to convince anyone otherwise...

I'm normally not a combative person, but since you're here(full of BS) spouting off about our lack of mechanical knowledge and inexperience I felt the need to say something. Good luck with your quad and the whole delusions of grandeur thing...

Well I would never thought thar this thread would go to this but OK... Don't ask for help if your going to be negative on our answers. Perhaps if you left out the mph you can achieve with the little 250ex would have helped some.

Isn't the 250ex shaft driven????

oh sorry 250X, still to fast for me....

Seems to me that any guy who could modify a little 250X to hit 93 mph could fix his transmission woes w/o our help.

      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.
