Checking and installing cylinderhead on a Honda XR600 1987 PE-04. Plastigauge Valveguide measurements Lapping the valves (not included in video, see in-video link)
Hi man, great and super informative video! quick question, I have recently picked up a 1994 NX650 and had to change the loose cam chain tensioner, I am getting a new cam cover gasket. the manual shows to use the on without the cut-out at the top, but you show yourself at (7:48) using a alternate one with a cut-out, is it better flowing or just a preference thing? thanks for your help!! :)
Thanks, great engines mr Honda made. XR400R is also really interesting! I think a better oilpump design what i saw. Hopefully you will don't need this kind of big rebuild action, but if you do it's a lot of fun!
I’ve got an 85 XL600R that I recently bought, got it running after cleaning carbs, new plugs and oil. I’m having issues with the bike spitting oil from the tailpipe, do you think that’s likely valve seals or rings? I was hoping it would clear up but if not I’m definitely checking out the rest of ur vids if I have to tackle taking the top end apart. I can’t wait go get this thing road worthy, great work man!
Thanks Omar, compressiontest perhaps first? Of leakofftest? if you do a leakoftest and air is heared from the valvecover(screw cap of) than you loose air through the valveguides. taking the head is a good idea, the only thing is you have to tilt the engine in the frame to get the rockercover off. Tip: replace spanner and chain when you do, if you find helicoils replace them with long ones. Good luck!
Had a 650L AL baker model big fin kit flat side Mikuni big bore kit port polished head man what a bike nothing was left untouched on that bike !!! Now o have a well built mint 2003 XR 400 better trail bike!
Hi. thanks for great XR engine videos, they are great help. Just put my rocker cover back together after painting today. Watched this episode like 10 times and when double checking if done everything ok I notice that you put wave washers on exhaust sub rocker (6:38)on opposite side than Honda drawings shows... Have you noticed and correct it or running like that, just wander?😀 Kind Regards.
I had a closer look, seems like you're right! I was checking the parts diagram www.cmsnl.com/honda-xr600r-1987-h-belgium_model6867/partslist/E__0300.html#.Y2lptHbMKUk And looking at how i assembled it it looks like i put in on the other side ...
I guess engine still going strong so maybe these not matter that much.. :) its Honda after all :) You have done great job with your engine, envy you ;)😃👍
www.cmsnl.com and ofcourse the ebay. Germany: www.kleinanzeigen.de Netherlands: Marktplaats.nl And parts in netherlands: www.offroadcentrum.nl/ lanstech.nl/ Check if the camjournal isnt too bad, and the cracks around the sparkplug arent too heavy. good luck
thanks for this great video man, it is much appreciated as I just purchased another 85 XR600 r and have motor to go through, doing a complete rebuild, any recommendations for part I may need, the cylinder looks good but was left out in weather wit top head removed, so piston rusted in there
Remove rust with "Scotch brite" , but do it outside. The scotschbrite dust will ruin every bearing in sight in your mancave, also rinse very good before you actually install the part. But when the rust is removed, i think you should give it a good handhone like video nr 6, and then measure what the result is. If the space between piston and cylinder is too big better bring it to an engine shop to let them bore/hone it to an new oversized piston. Good luck!
it's the 1987 model. Can't order it oem, so there 's a guy in israel that sells them on Ebay. But check for the quality, some do hav irregularities on the camlobes.
Understood. Im on a tagged 97. Love the bike for camping destinations under 100 miles away. Noticed there was a gear on the cam as well. Is that for tach?
@@WAYSTOGOFORWARD It's for the XL600, those have RPM in the dash. 1 rotation of the cam is 2 rotations of the crank. Its universal for the XR and the XL
the camshaft i ordered had the wormwheel in the middle normally used for the rpmcounter. I ordered the camshaft from israel, be aware. The first one he send me wasn't 100%. I send the cam back and he send me a good one. The first one had casting impurities.
This is a GREAT series that i am going to need. Bought a 87 XR600R that didnt run 1.5yrs ago - rebuilt carbs and got it running but not right. Found out after its an XR frame with an 87 XL600R motor. I split the case and am slowly acquiring the parts to reassemble, some new (rod, piston, etc) and some used like trans gears. Rod bearing was sticking bad, going to have that rebuilt and bored to 102.3mm. Got most parts but i have a question i hope you can answer - the decomp assembly in the head - mine was pretty loose - how tight should that be when trying to rotate it by hand? when i got it, it would not return on its own. thanks for the series!
Hello Tom, good to hear you have found yourself a nice bike! My cable was too tight, so when i turned left sharp the engine stalled (decompr activated without knowing) so i loosend it. For how tight it should be, i can turn i by hand and i can push the rocker in a bit. But it should return automaticaly by the spring! Look at nr3 in the drawing www.cmsnl.com/honda-xr600r-1987-h-belgium_model6867/partslist/E__0100.html#.YN4iPOgzaUk
@@cjsgarage3662 thanks! It was not returning on its own and had lots of play. I am assuming it was the spring or it was installed incorrectly. Should the spring have enough tension to return the decomp lever on the handlebar. Squeeze mine and it just stayed where you left it 😜
@@tomphillips2473 It should definately return! Deconnect the cable from the decompr arm on the cylinderhead. Just feel how it moves on it's own. It could be that it's installed the wrong way. Bit of work, but it would be good to take the cylinderheadcover off to get a look at all the stuff inside. HOw the oilbearing looks like etc, all the rockers. Gives you a good view how the state is. But first take the cable off, see how it moves on its own. If its fine, hava a look at the cable itself! Greetz CJ
Does somebody know, why i can't thighten the 2 bolts properly at 5:10 Min? The motor is in the bike so i tried first gear + rear brake, also holding the bolt with which you can turn the crankshaft didn't work. The camshaft keeps turning while trying to thighten the screws. The camshaft was properly aligned on Installation (now it might not aligne anymore). The bolts are mounted on the opposite side than in the video. When turning the motor over everything works fine :/ My Motor: NX650 RD02 1992
ah, differetn type of cam. You have the automatic decrompressioner offcourse. But....... take the flywheel cap off. Put a socket on it, perhapsyou can now tighten the bolts while holding the flywheel. Take note if the sprocket is still on time while TDC, the bolts are with locktite at the right torque for your bike, and like you did always turn by hand just in case. Good luck,
i bought one in isreal on ebay. But i think its better if you let your old cam be refurbished (they weld an extra layer onto it and trim it to OEM spec). That's what i would do now. The valve clearances you can find in the ownersmanual. Mine were: IN: 0,10mm EX: 0.21 mm

i think i got two types in my gasketset. I used the one that i found on the engine when i tore it apart. .
Very detailed thorough work. I have an 04 400r. Would love to be able to tackle this if I ever needed to. This helps for sure
Thanks, great engines mr Honda made.

Hello. Did you get one of those camshafts from Israel on ebay? How is it working for you?
@@ilmarasciallo still fine, i looked in the camcover after some miles. No crazy stuff, looked ok. You never have full certainty. Its what it is.
Horrible music, jeeez. Silence would be golden! !
ain't my music, had to be cheap :) all the money went to the rebuild ;)
What a great engine the xr600 is 👍🏻
Pretty ol’ girl ain’t she. Hard to beat a Honda for reliability.
until the checkvalve is blocked ;)

RFVC is one of the worst engines honda made if not the worst. Yamaha TT and Kawasaki KLX were superior.
@@anthonynicholich9654 there are definately points that could be better. The oilpump for instance, strange.
but compact and tough engine for the rest

What brand cam is that? I have never seen one have the mounting surface toward the motor. I have installed stock cam 2-3 times and now on hot cam.
it's the 1987 model. Can't order it oem, so there 's a guy in israel that sells them on Ebay. But check for the quality, some do hav irregularities on the camlobes.

Why replace helicoils?
i heard a story yoi should replace them always, but these were bad anyway.
I just bought one of these what all kind of carburetors off different models will fit
www.cmsnl.com/ look the bike up, look at the partnumber and see which bikes also use them :) Works super
Как купить новый карбюратор ?
there is only used, this is a 1987 twincarb.
@@cjsgarage3662 новый есть ?
Been looking for one of these around the Tennessee area for couple years ....not even a basket case to be found ....
The bike? Or the head? The dual carbs are cult, but the later singles are also really good. Or a xr400r?
Hey! Hope you are doing great! I wanted to ask where did you buy the camshaft and do you know where i could find valve clearances? Thank you!
i bought one in isreal on ebay. But i think its better if you let your old cam be refurbished (they weld an extra layer onto it and trim it to OEM spec). That's what i would do now.
