Man I have nothing but great things to say about namura pistons. I am on about 7th namura piston and have never had one to fail. I mean on 7 different builds....from cr 80's to predator 500's. By the way I got the crank you did installed and she's rippin. I'm in need of a 92 rm125 cdi box though...lol.
I appreciate the information. I don’t use them often because I was unsure of the quality. Glad to hear you have good luck with them and maybe I’ll try some in the future. Glad you’re enjoying your RM. Unfortunately, I don’t have a CDI for you for that machine right now.
@restoroosterohv Thanks man but I found one in Slovokia of all places. Also I have been using Namura and pro x for these 2 strokes. Namura is about half the price of pro x and in my opinion about the same. The tolerences on the pro x are a little bit tighter though.
The tolerances could end up being key. I generally don’t have them long enough to do any endurance testing on them and obviously don’t want to pass any flawed items onto the next guy. I appreciate you giving me some real world feedback on your success stories with these parts.
@@restoroosterohv I did a full frame off rebuild on a 2009 YZ250F. It wasn’t until I had the whole bike done, rebuilt and running I realized what I think originally caused the bottom connecting rod bearing failure. Someone installed a works connection guard on the right hand side of the bike under where the water pump cover is. Ironically the oil line rubbed though on the very device put on to protect it and leaked the oil out.
Excellent video Just subscribed. I just got a 2005 yz250f to very clean. it runs great the only thing is 5th gear is blow out. It shifts super smooth up to 5th to then 5th is crunchy neutral. I just decided I’m going to do a WR transmission swap. According to old forms it should be a direct swap. going to upload a video of the swap on my channel to. ordered a mint 2013 wr250f transmission, all oem seals, timing chain, and bunch of other stuff.
Great videos very thorough by chance can you post the model or number of the case bearing I see it’s Koyo and where do you get it? Thanks keep up the great content.
Thanks for your feedback and support. The Koyo bearing is double sealed so be sure to remove one of them and put the bearing with the seal facing in. www.ebay.com/itm/163734036258?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=4qcIU-gFTJm&sssrc=2047675&ssuid=K8gv8TS9R3W&widget_ver=artemis&media=COPY
I’ve been doing it for a long time so I have developed some feelings when it comes to torque. I agree with you (and other viewers) and always torque my bolts for the videos now. Thank you for your comment.
My favourite chanel without doubt, you have my support from Spain! jejejje. I have a yzf 250 2008, Is it normal that my camshaft does not rotate smoothly and I have to use force to make it rotate? Should it rotate smoothly? This happens to me after adjusting the valves.
One of two things is happening, either valve clearance was not properly adjusted and is too tight where the camshaft is dragging on the lifter or the cap was overtightened and is now slightly warped. Set your camshafts with the timing marks in the proper position and recheck your valve clearances. If they are fine, then there is a good chance that the cap has been tweaked a little. It is extremely critical that these are torqued properly.
As a bike builder, bottom ends top ends etc.. do you do flat rate pricing on bottom ends on labor? I’ve done 50 or so. Just curious. Love your channel!
I generally don’t use titanium valves on my rebuilds due to the cost. I use stainless steel. You are absolutely correct, titanium should not be lapped due to damaging the coating. Thanks for watching and for your comment.
Another good one . Now I have a question if you don’t mind , I have a 2012 kxf 250 with a snapped cam carrier and damaged head. I’m struggling to find a used head for this year are there any other years that I can used a the cylinder head from? Other than the 11/12 models .Thanks mate appreciate it.
Thank you for your support and feedback. Unfortunately for you, the 2011 and 2012 heads are the only ones that will work on your machine. Not sure what your budget is but there a few complete heads on eBay now. You could also check Marketplace but beware of scammers. Good luck.
@@restoroosterohv sorry for late reply. I’ve just read that apparently the 09 /10 heads fit but they don’t have the temp sensor on like the 12s do . I know in terms of part numbers they are the only ones. Is there any other reason why the 09/10 heads won’t work other than the temp sensor?. Also I’m in the uk and there isn’t a single used 12 head on any of the sites . Not even marketplace .
@bardy9240 I don’t want to steer you wrong here. I unfortunately don’t have any experience with using 09/10 cylinder heads on the 11/12 so I’m not going to be much help to you here. The temp sensor is extremely important and will cause starting issues if not installed properly (see my “Hard to start” video on my KX450F). I am building a 2011 now and I need the head otherwise I would certainly sell it to you.
@@restoroosterohv no problem mate . I know you would help out if you could , I’ve watched all your videos you’re as genuine as they come . The temp sensor housing is present on the 09 head I’ve been advised it can be drilled out and tapped. A new bare head here is £670 valves £240 for intake and exhaust without springs and seals etc. this used head is £425 complete .
@bardy9240 believe me, I love to save money. Let me know if that works out for you. I might be able to help someone else out in the future that has that question. Good luck!
Alot of power in fact, too much power, soo many of these bikes rods blow up due to the high RPMs, bought a 07 YZ250F to rebuild and the rod grenaded and destroyed the cilylinder and two valves are bent
I love your 2005 yz250f rebuilds it’s great
Thank you
Your video is top notch, my son and law and I rebuilt a YZ... 2005, top and bottom. Thanks to you build came out perfect! You are awesome!!
You are awesome for your support! Thank you.
Hey mate, thank you for the videos
Thank you for your support!
Love your videos buddy. good workmanship from you. And a love yamaha and susuki ktm kawasaki etc b7t have a 2t yamaha myself, so into yamaha.
Thank you for your feedback and support
Love seeing non runners back up and running 🙌🏻
I agree. It’s satisfying to give a neglected bike another chance. Thanks for your support.
Great channel..
Thank you
I like the finishmaster shirt. I bought a lot of standox from them. I enjoy the videos keep them coming.

Absolutely nice project!
I just finished a project with a rmz 450 2005
Thank you. I don’t do a lot of Zukes strangely.
where did you get the block off plate (with c clamp?)/ plug from, currently looking for one to put an 05 head on my 07 with the carb hot start
Not sure what you are referring to.
I really like these videos, all respect
Your support means everything, thank you
Great work, however, you forgot to adjust the muffler bearings as you could hear after it was started.
Haha, yes you are right. The kaniffler pin fell out.
Definitely a good call taking the bottom end apart. worth checking
Agreed. Would have been an issue for sure.

Yes, depending on how deep I get. For example, a crank and bearing replacement would generally be $400 + parts. Thanks for your support.
Do you ever work on older XT600s?
Not normally. I did a full restoration on an older XT350 many years ago. Did you have a question?
Were those titanium valves? I've heard a lot of folks say it's not the best to lap titanium valves.
I generally don’t use titanium valves on my rebuilds due to the cost. I use stainless steel. You are absolutely correct, titanium should not be lapped due to damaging the coating. Thanks for watching and for your comment.

Sometimes they come through the cases...like in my 2012 YZ250F build Ep25
@@restoroosterohv yep, my bottom end has two holes, on top and in front
If the actual head is OK, depending on what you paid for the bike, it may be worth sourcing the parts to rebuild
