Dang this channel isn’t as big as it should be, there’s good info and the videos are well put together. Thank you I’m currently fixing mine in my shed right now :)
Thats so nice of you Nathen. So glad you like the content! And, the channel is growing! Hope to hit 300,000 in a few years!
You sir have earned my sub absolutely love your detailed videos ive watched a few..many other content creators just fly through the process thank you for your time
Cool! Thanks. Hit 1000 recently so Im stoked!
Super video Brian, having trouble with my Son's cr85 and your bit by bit explanation gives me confidence to tackle the job. Only problem is the specialist tools required for some bits of the breakdown .
True, but its cheaper to buy the tools than have someone else build it for you. Thats actually what got me started building up my own motors
Your videos are GOLD
I’m so glad you find them useful! Thanks so much for watching!
great video
Thanks Wayne. Got a new one coming out in the next week after a few months of inactivity. Thanks for watching!
Great detail content on the cr85 new subscriber here im working on 2 2007 cr85 possibly a 3rd lol they are really fun to work on , that kick starter reassemble always takes me for ever, keep the videos rolling 🤘💪😄
Ya, nobody really explains how to properly wind the kickstarter. I had to just do it by feel.
Im building a new one up now. Its going to be sweet!
Great work!!
Thank you! Cheers!
Are you still active I am working on my 2006 cr85rb expert and currently rebuilding the bottom end the shaft rod shot out the bottom and my father I'm law is welding the case and I am ordering the rebuild kit bit I am needed help getting the clutch bolt off. You made it look easy
Hi Spedest. Sorry to read about the clutch bolt. I have never had much trouble removing one of those. Use an impact driver and a clutch basket holder (if you can find one) and it should come out. You can try heating it too, but be VERY careful as you don’t want to overdo it. The clutch basket cover is aluminum and can warp if overheated.
Buen video amigo saludos desde Perú....un favor debe traducirlo ah Español para poderle entender gracias
Me alegro de que lo haya encontrado útil. ¡Gracias por vernos!
You should do a transmission video. For proper placement of washers and gears one primary and secondary shaft
I will be doing that video this summer. Stay tuned!
Thank you sir
Sure! Glad to help!
The one im buying has been sitting in a garage for years I’ve actually seen and started it in person they said it hasn’t started in two years and I got it after 3 kicks
Hey George! That’s cool! I bought a CT70 that had been sitting for years like that. Cleaned out the old gas and it kicked over, no problem!! It’s a nice little surprise when stuff like that happens.
Hey Brian, can you tell me what size flywheel puller to purchase, I am getting ready to rebuild my CR80 shifter kart engine. great videos!!
In the description now! Thanks!
i need a whole new crankshaft can you make a video on how to replace one and is it possible to do it without taking the engine out?
Haha! Is today April 1st? Good one! Thanks for watching.
The left side, the sprocket side, is that just a plastic cover (1:10)? Can it easily be changed or does it require seals, etc?
Hi Aaron: I dont see anything at 1:10 that is a plastic cover. At that point in the video, I am discussing the procedure for the removal of the head and cylinder. Thank you for watching!
I will watch this until I know it like the back of my hand
Hey BIKELIFE! Read the service manual too! It helps!
Great video
Glad you enjoyed it! Thanks for watching.
The nut on the small gear that stops the clutch basket from coming out, is very stuck... feel like if I try any harder it'll break the gears or something.
Hey Ryan. I’m not sure how to help you on that one. Just make sure you’re loosening and not tightening.
@@brian.d.mobley Thanks for the response. Definitely loosening. Going to try an impact gun next, hopefully I don't destroy the gears... lol
@@ryanlahay9361 if you want to send me a pic or short clip to my Instagram account by direct message, feel free. I’m glad to try to help, but I’m not sure I can do much.
Kickstarter installation??? Both of my timing marks are lined up but my kicker won’t go backwards it only moves forward
Looks like a socket that you used to punch out the sleeve right? Metric? I’ll try to pick one that is the same size if so. Your videos on the 85 are so helpful!
Johnny Wishbone - Psychic Extraordinaire from the island of St. Croix! 🤣. Hey Johnny! It was a socket. And the socket was connected to a normal socket drive extension. I don’t recall the size, but as close to the OD of the sleeve as you can find. Thank you for watching!
@@brian.d.mobley Thanks for the reply. I ended up dropping the case off at a Honda dealer because I was afraid of damaging it myself. Was charged almost 1 hour labor ($103) in case any of you are wondering what it might cost. The collar/sleeve was very rusted!
@@johnnywishbone1349 Ive pulled out some super rusty ones too. And its not fun. I don’t really care for using fire as a tool for what is otherwise precision work. It just doesn’t feel right somehow. Anyway, glad you were able to get yours services and that you can move on to other work.
@@brian.d.mobley I’m a few weeks out to having this 2001 CR80R complete. I’ll have to upload my first video when it’s all done! Can you help solve a mystery about the rear swingarm? On each side there is 1 bolt for the chain adjuster that goes into the swingarm followed by 2 nuts lol and on my bike it’s not threaded. Do you remember if the swingarm was threaded on your bike to accept the bolts?? Tusk sells a swingarm chain adjuster bolt repair kit so I’m thinking it might be...
@@johnnywishbone1349 Man, I’m sorry, but I am not sure. I have only owned CR85s and I think swingarms on CR80s are not the same. If you have the service manual, look in there. You can usually figure it out most easily that way.
My shift shaft just keeps pushing in whenever i try to put my shifter on
Hey CRF150. That’s very strange.
Brian, If just wanted to change 3rd gear (kart racer) to a billet gear would I still have to completely remove the crank?
Hi Aaron. I’ve not heard of a billet gear on a kart, so I’m not exactly sure what you mean. Is this the drive gear that connects to the chain or some kind of billet aluminum transmission gear? In either case the crank should not be affected. If it’s the former, changing the drive gear is pretty simple. If it’s the later, the transmission can be removed for gear changing while the crank remains in place. Hope that helps.
My head bolts are super tight. Any tips? Don’t want to strip them. Are they reverse thread? I have 2005 cr85
Hi Henroo. They are NOT reverse thread!!! Dont turn them the wrong way!!! Those studs can get pretty rusty. Have you seen the "double nut" technique where you tighten two nuts against each other on the end of the stud and loosen? I have sheared studs off myself and its total bummer. If they dont come out using this technique, add heat to the surrounding aluminum. Even this is not always successful. But, heat and double nutting and being strong are the best techniques I have found.
I enjoyed watching this, thank you! I plan on starting a full top and bottom rebuild of 2005 CR85R in a few weeks and will be coming back to this for more details. i subscribed, feel free to check out my channel and sub!
how did it go?
@@5.0_foxbody life happened and the engine is still in a box on a shelf. I will hopefully get to it this year!
@@GrowYourOwnFun dang i feel you on that
I have a cr85r 07 it’s been out in the weather and stuff but my bottom end is still tight and no up and down play looks like just need a top end but I was concerned since it’s been out there what other suggestions should I look at
Everyone is different, but if it was me, I would completely rebuild ANY motor that has been left outside in the elements Water will RUIN a motor.
I split the case and my crank came out in the right case
Hi CRF. I’m not sure if you are asking a question or just giving me a report about your engine build.
@@brian.d.mobley asking a question i noticed your crankshaft came out in the left case but mine didnt
@@Hi-vw6dg If you have a puller, you can pull the crank out. You can heat the cases a bit and pull the crank out without much difficulty
I wonder if the 85R bolts right onto an 80R frame. And just swap out the CDI.
Hey RNR. I can find out for sure. I think so. I’ll get back to you.
@@brian.d.mobley Thanks!
@@rocknrye9273 From 1996 and newer, the swap will work.
@@brian.d.mobley Awesome! Thanks for the reply back. I have a 97 ☺
@@rocknrye9273 Start wrenching! Ha!!!
Very very great and helpful video. I have a question though, where did you buy the special tools you used? Any links?
Thank you sir. I have one more question, my cr85 has a leak in the middle gasket (crank area). Can i just remove the left side and change the gasket? Instead of removing the right side? Thanks.
Awesome. Thank you very much, very informative.
Omg mine has the same problem I hope it’s not this
Thx ..nice ...
Thank you too!
I’m new to bikes but I have a cr85 and the rear tire locked up and the Kickstarter did also what do you think is the problem?
Hey Vinnie. That sounds like a stuck piston, unfortunately. Did you mix 2 stroke oil with your fuel before running the motor?
@@brian.d.mobley I think I was just going to hard on the engine but I’m going to try to look at the piston and cylinder but thanks a lot for your help keep up the good vids
hello sir my Cr80 is mix water and oil so that the oil will be come milky what is the problem sir?thanks in advance sir May I know sir
Hi Sherwyn. The usual reason is the failure of the seals in your water pump.
@@brian.d.mobley thank u so much sir for the info.from Philippines I learned a lot of you 😊😊
@@sherwyntamag9157 It seems dirt bikes are very popular in the Philippines! I get a lot of questions asked of me from that region of the world. Im so glad my videos have helped you! Nice comments like yours are what keep me motivated to keep creating them!
Do you know where I can get all the specialty tools used
Hey Landon! This video is a little older. Now I include all the tools and supplies I use in the description box. I just havent made the time to add that information to my older videos. That said, I got most of the speciality tools from Rocky Mountain ATV. Hope that helps! Thanks for watching!!
@@brian.d.mobley what size was the puller
@@landonsanford5342 I am so sorry, but I dont recall. I have a puller kit and the correct size was supplied it the kit. amzn.to/3ucKqow
Is there away I could get in contact with you
Where did you get the case splitter
Hey CRF Rider! Im so sorry for the late reply! Busy holiday weekend. I got mine on Amazon. Here is the link. amzn.to/3jSJMJA
@@brian.d.mobley also can't seem to get the clutch basket bolt out
@@Hi-vw6dg Right!? More tools needed! amzn.to/36hgPyZ
DO A CR125 2002
If you have one that you want me to rebuild, send me yours! I’ll do it! I want to do a new 125cc video.
Where can I find the ignition holder tool?
