Hi, Anonymous and the usual suspects are:
1. Clutch not adjusted properly.
2. Primary chaincase overfilled with lubricant.
3. Corners wore off shifter clutch dogs.
4. Shifter return spring bent or broken.
5. Bent shifter rod.
6. A loose shift lever on shifter shaft.
7. Shifter forks sprung.
8. Shifter pawl needs adjusting.
9. Heel/toe shifter coming in contact with the floorboard.
10. Transmission oil too heavy.

1ST of all i think you should take your bike to another dealer to get it fixed as they should be able / confident mechanics to repair any problem.
But anyway have you checked the throttle position sensor ? of the fuel injector connections ?
just that water could of coroded the connectors.

Why does my cr 125cc 2001 smoke when i start it but then clear up and spit oil on to my swing arm and out the exhaust

Excessive oil in the exhaust could be worn out piston rings. Has the bike ever had a top end rebuild? If it's been ridden even moderately in the last 10 years, it's probably due for a new top end.

My bike wont change out of secound gear

This usually means a bent shift fork. Quite likely the shift lever is hard as a rock. The engine will need to be torn down to get to the bent fork or forks. Bummer. Please rate my answer. Thanks.

My bike will not **** into 4th!! it goes into all the others just not forth. Does anyone have instructions on how to fix it?

The bike has a bent shift fork. The engine comes out and the top end gets dismantled then the gearbox dismantles and then splits in half. Now the gear sets come out and you can get to the shift drum and shift forks. I don't recommend a complete engine tear-down be done if you don't have the special tools needed and some serious experience. The shop will fix it for $750 to $1250. Bummer. If you do try the repair, don't start without a factory service manual.

I put a new shifter on my honda 125cc motorcross and no it will not shift gears. the shifter moves up and down but does not feel like it is shifting gears. what could be happening?

Did your bike shift gears prior to installing the new shift lever? Why did you replace the lever? If the bike was dropped and the shift lever damaged, the shifting mechanism inside the engine may have been damaged as well. This mechanism will probably be on the primary drive side of the engine and you'll probably have to pull the clutch drum to get to it.

I have a Honda XR650R 2001, in nuatural it keeps tryin to lock up

You have a bent shift fork not positioning the slider gear fully into neutral. The engine will need to come out of the bike. Remove the top end, the flywheel and electrics, the clutch, shift mechanism and kick starter and a few other parts. THEN you are ready to split the gearbox to get to the crankshaft, gears and shift forks.

You will need an impact driver, flywheel puller, case splitter, torque wrench and factory service manual, plus the normal screwdriver, pliers, etc.. Alternate to the special tools is taking it to the dealer. I normally tell people to take it to the shop just so they don't get into such an involved project and they have a knowing eye working on the engine. The diagram below shows how a shift fork moves a slider gear left and right to change gears. A slightly bent shift fork is not letting the slider gear "dogs" fully dis-engage 1st gear.

Stuck in gear

The bike has a bent shift fork. This means the engine comes out and must be totally torn down to fix the bad fork. The top end comes apart, the flywheel, electrics, shift shaft, clutch, main drive gear, kick starter, shift drum index wheel assembly all come apart then the gearbox gets split open for access to the shift drum and forks. This is not a job for the home mechanic. You have a few more problems I had best mention.

Most bike shops will not repair a bike more than 10 years old. Your bike is almost 40 years old. At today's repair rates it would cost around $500 to $600 for a shop to do the repair. That is probably more than the bike is worth. I searched the web and found a source for the original Honda shift forks. In round numbers they are $40 each. You should only need one fork. There is so much that should be done, all new bearings and seals, piston and rings, valve guide seals, and valves re-seated. Getting a gasket set could be a problem also. If I personally had the bike and it was really clean and nice, I would fix it up. But bear in mind, I have the tools and know how to do it in just a few hours and all it would cost me is the cost of parts. Paying the shop charges is the killer here.

No problem just done top end rebuild

Just ride it normally. Avoid super high revs when the bike is not in gear and using the power.

Please rate this solution. Thanks bookerm!
