Probably $900 at the shop. Price it out at a few shops. The entire engine gets torn down. Be sure to install new crankshaft end bearings and seals as well as shift shaft seal and sprocket outer bearing and seal. A flywheel puller, impact driver, case splitter and torque wrench will be needed. Sorry for the pain.

Could you take a moment and rate my answer? Thanks!

Whats a lower rod bearing for a 2002 cr250 and can i put it in at my house??


The bearing for the lower end of the connecting rod is pressed between the crank halves. Most people would just replace the crank and rod assy. as the crank must be rebalanced after pressing a new bearing in.

Kickstart is jammed will not move bike was running then just stop


Most likely you have bad main bearings and/or lower rod bearings. In the process, this usually takes out the piston and cylinder, too. Repair will require a total rebuild.

Want to know what parts i need to replace my lower connecting rod bearing on 99 suzuki rm 125 and the best place to get them


Understand that your bike has a pressed crank. A shop will need to press the crank apart then press it back together and align the crank. I suggest you go to Babbitt's for parts.

New crank main bearings are highly recommended.

Need to replace lower connecting rod bearing, possible crankshaft! is this difficult


To replace just the lower connecting rod bearing is difficult. It needs to be pressed, and then trued to specs. If this is not done correctly, your crank will destroy itself very quickly. Buy a crank, and replace the bearings and seals on the left and right of it.

How to remove lower bearing on connecting rod in a yamaha yz125.


I'm not 100% sure because I have'nt had much dealings with yamaha dirtbikes but I do know that on Hondas and Kawasakis there are no rod caps to remove the rod from the crank, the crankshaft actually splits and the rod slips off. They are a very tight press fit and have to be reassemled perfectly or it will throw the whole balance of the engine off. I recommend taking it to the dealer and letting them do it. I know that on my Honda CR 125 instead of trying to replace the lower rod bearing I was able to purchase a crankshaft with a new rod already attached. Hope this was helpful.

First bike do i mix the oil and fuel on a 06 cr


If this is a Two Stroke Motor and it does not have Oil injection..

Then Yes and if your not sure it's safest to mix rather than not..

the worst you could do in the following situations is:

- if you have a 4 stroke
foul a plug and make smokey exhaust

- if you already have oil injection and your bike is 2 stroke, youll foul a plug and make smokey exhaust.


if were to run without any oil in a 2 stroke or too little....

you will sieze the piston rings or the lower crank bearing.... Very expensive to fix...


You actually sometimes have a second of notice from the motor that its about to blow .

when runnin too lean on oil ( too little )
the mototr all of a suddon picks up power on it own, just before it siezes:
this is becaus ethe lower crank bearing a are red hot and the gasoline is vaporizing as it passeacoss them on it way up through the ports,, this make the fuel super volitile..

Sitting on the bike, give it gas and it sounds like a rod bearing.


It may be.
Be sure the oil supply is not empty (if it is a 2 stroke)
