Thank you for your videos! I just did my wife's CR85. The one thing I got wrong was the Kickstarter. It looked to me like the spring was entering the rod at the 6 o'clock position in the video. I took it apart twice before I purchased the manual and realized it needed to be at the 12 o'clock position so as to separate the gears when the block on the bottom gear hits the stopper plate! I should have been looking for the split in the pink plastic piece. I am an idiot! Great video my friend!

Youre are not an idiot. I put the water pump seals in wrong not long ago! Nobody is perfect! And, its a lot of steps to do just perfectly when you build a motor.

Excellent vid, I'm getting ready to do this with a WR200 engine and still waiting for a few parts. The other day I put my (old) crankshaft in the freezer and heated up the old main bearing inner race to do a test fitting and it slipped straight on (and then became impossible to remove without a bearing puller when it reached room temperature so all good). My only concern is how do you keep condensation from damaging the main and big end bearings? After a few minutes out of the freezer my crank was wringing wet as it warmed up. Thanks, hope you can help!

[@brian.d.mobley]

Hey Alex! Great question! In the short run, you can spray the crank with WD40 after installation. However, if you store your bike in a garage or other space that has no humidity control, condensation will always affect the internals of your motor after assembly. To mitigate this, start the motor once a month or so and let it warm up to operating temperature. Thanks for the comment and for watching!

Would you recommend lubing the case faces? You are talking about it at 3:37 but I’m just scared that if I do this to the cr85 I am working on it will create an improper seal.

Hey Bluegrass. The reason you lube the gasket or the faces is to make it easier to disassemble the cases if they need servicing in the future. But, you don’t have to. Most engine builders that I know lube either the gasket or the crankcase face. I now lean toward lubing the gasket because it’s more convenient.

Hi. What is the thickness of the head gasket? (squish)

[@brian.d.mobley]

I have never seen a spec for that which makes me think they don’t have wide variations of tolerances. Bottom line, I don’t know. Sorry

[@joekambulu7302]

I need that engine

@@brian.d.mobley I want that engine cr85

[@ignasignas568]

Hey, can someone explain, this is cr85 and why on the engine marked 600cc?

[@brian.d.mobley]

That is the crankcase oil capacity for the gearbox.

[@hunglikedonkey]

wonder if you can help, my bike has lost it's breather pipe, does it just vent to the open air or is it supposed to connect elsewhere - thanks

I have a cr85 im working on and bought a new head gasket put on and leaks out head gasket any Ideas ?

[@brian.d.mobley]

Hi Richard. A few things come to mind. The head may be warped. I go over that in another video titled "Tips and Tricks for Measuring Your Top End." Another is the torque specs for the head are not correct or not the same on each of the four head bolts. Check these first. If your problem is not solved, let me know.

Hi brian sorry to interrupt but i also have a cr85 2007 that needs a rebore. I have taken it to my local bike shop and they said its got a steel sleeve in the barrel and it cant be rebored / honed have u any idea if this can be fixed ?

[@brian.d.mobley]

@@jakeubbb265 I’ve seen those sleeves on sites like eBay. Honestly, I’ve never dealt with one so I’m not really positive about honing or boring if a sleeve has been installed. However, look up Millenium Technology. The do Nikasil repair and have a good reputation. They answer me promptly when I have cylinder questions. Email them. They are better equipped to give you a reliable answer.

Hello! What size wrench is needed to tighten the center bolt of the clutch basket? 14mm or 17mm?

[@brian.d.mobley]

Hi Hasek. Im so sorry, but I dont know that off the top of my head and I dont have any open motors at the moment to determine the answer. Hopefully you have both sizes and can try them out for yourself. Thank you for watching!

[@Вродеигачавродебасик]

@@brian.d.mobley Thanks for answer. I found the answer to my question - the bolt has a wrench size of 14mm. Thanks for very interesting and useful video!

How far is the shifting drum supposed to move cause mine doesnt feel like any other dirtbike tranmission ive ever used but i have all 6 gears but it doesnt click into gears

[@brian.d.mobley]

Hi Send Memes. Im not sure exactly what you mean regarding drum movement. Lateral movement like runout or rotational movement while shifting. If the engine is operational, can you share with me whether the transmission comes out of gear during operation?

[@sendmemes5474]

@brian.d.mobley it pops out of gears in first and second like there false neutrals and the shifting drum the pins that slide out into the drum to pick the slot to move it in the next gear don't do anything unless you actaully jam the shifter or kick it down or up one thing I do know tho is I will never be buying another honda after this bike tho complete lemon clutch wont engage nothing works on it and I've put over 50 hours into this engine alone

[@sendmemes5474]

Hey i have a 1986 cr80r, are the shifters the same through the years or is it a specific shifter like I'm seeing? It has a stripped shifter shaft (which i found a replacement) now i just need to find the shifter. Any recommendations?

[@brian.d.mobley]

Hey Daniel! Id hate to tell you something that might be wrong. I dont know that off of the top of my head, but its easy to research. Go to a site like Rocky Mountain ATV and search their OEM parts. You can search by year and model. If the part numbers are the same between years, you are good to go. If you are on Facebook, you can join the CR85 Owners group and post the question there also.

Hey man, This video was a very LONG time ago. but on the clutch side did you have any reverse threads like on the hub or primary drive nut?

The only reverse thread that I recall is the center bore of the flywheel. The thread onto which you thread on the flywheel puller.

For someone who loves his lube you sure didn't go in to deeply on ring end gap...

Not sure what lube has to do with end gap, but I made a complete video on top end measurement and I’ve never once come across an ring that was out of spec on a cylinder that was within service limits.

Do I cut the gasket after closing the case up the gasket has a line where the piston go do I leave it or cut it
