Hey man ! Hope your dad wasn’t injured from the crash years ago. These are pretty tough motors so as long as it didn’t bust the motor case, most times they can be resurrected. Hope the videos help some along the way and all the best ! Steve

@@StevesDIYs He broke his ankle, but it's had three decades to heal so he's fine. The engine is fine on the outside, but its been sitting for said three decades with oil and fuel in it so im not exactly excited to look inside. If you say that it can likely be saved I'll take your word for it and give it a shot, worst case scenario I have a cool new display piece. I appreciate the fact that you took the time to make a guide for these, I will use them well. Stay safe, cheers 🍻

Hi Steve, this series has been super helpful as I prep to teardown and rebuild my XV750 motor. Any chance you have a full parts list for everything I should replace while I'm in there?
@StevesDIYs

Thanks man ! Glad the videos help some 👍. Actually so far, for the three I’ve rebuilt, I haven’t really found any major parts that needed replacing other than the seals, gaskets, and the clutch friction plates. Even the one that had been sitting for years was in good shape on the inside. I usually buy the big kit that’s in some of the videos that has all of the orings and seals and just replace those as well as the friction disks if i thought it might have had issues. The kit typically doesn’t include the shifter seal or oring for the oil level sensor on the bottom so if those are leaking they have to be purchased separately. Hope this helps and all the best ! Steve

I looked out on eBay and the kit they are selling now does not include the 4 or 5 orange orings for the oil pump and in between the case halves so those would have to be ordered. Here’s the description to search for on eBay: “Yamaha 81-83 XV750 84-87 XV700 Virago Engine Gasket Kit Set - See note on XV700”. The gasket set is shrink wrapped onto a printed cardboard backer with NE brand on it.

Oh my god. I’m doing a rebuild on a 920. I’m following you and my timing is way off. What do I do? Can I still move forward and fix timing when I reassemble?
@StevesDIYs
2 жыл бұрын
Hello, yes you can for sure continue with the tear down as you’ll he able to set the timing back correctly when you reassemble 👍. Checking the timing before tearing it down is just so someone can see how everything lines up if tearing down a previously running motor so there will be more confidence that it is the same after rebuild. You’ll just need to be careful about rotating the motor until you get the heads off if it is way out of time or you could bend a valve. Towards the end of the series (and also a video on setting the valve lash in the xv750 playlist on the channel) show how to check the timing again once assembled. Hope this helps and all the best !

Great video. Do you mind if I ask where you got that intake manifold from?
@StevesDIYs
Жыл бұрын
Thanks man ! The single carb intake was actually on the motor when I got it (it was all in boxes from an abandoned build someone had started but never finished). When I did the build with this motor, I put some OE dual carbs on it so it’s just sitting up in the garage attic. I haven’t ever tried to set one up with it, but I just got some more parts bikes a few months ago to play with so if figured I might throw it on and compare how it does to a dual carb setup this year.

After checking cylinder two if you continue going clockwise to line up the T again the number one cam sprocket mark will be a180 degrees pointing down. Will the cylinder number one piston be at top dead center? The reason I ask is because I was given an engine disassembled and I can’t get it timed right. I get the marks correct but the intake valve on 2 and exhaust on 1 are slightly open. Both cylinders have 0 compression. Prior to my cousin tearing it apart the engine had compression. The bike wouldn’t run because he didn’t have the carbs tuned correctly.

Hey man, yep, the rear cylinder (#1 cyl) will be at TDC anytime the T mark lines up in the sight window on the flywheel, but like you said, the cam will be 180 degrees off and the arrow that’s on the cam gear will be pointing down. At that point, the valves should be tight on the rockers and will free up again when the flywheel is rotated a full turn (the rear cylinder’s cam pointer will be pointing up again at that point). Is it possible that the heads are swapped? There is a little “1” and little “2” stamped on them near the cam sprocket cover. Or is it possible that the cams are swapped in the heads? The front cylinder cam is different than the back one I believe so if they are swapped it could be throwing off the timing of when they close the valves.

Hey Steve, super basic question. I am doing a top end rebuild on the front cylinder due to finding oil on the plug. I am just planning to pop open that one as I kinda have a "if it ain't broke don't fix it" mentality regarding the rear cylinder as it seems to be fine. Do I need to mess with the timing chain for the rear cylinder at all if I'm not planning on working on it?
@StevesDIYs
2 жыл бұрын
Hey man ! Yep, I’m like you...I don’t mess with stuff if it’s working right (unless I’m doing a full rebuild). The timing for the front and rear cylinders are independent so it would be no problem just to pull the front cylinder for a rebuild 👍. It wouldn’t change the timing of the rear cyl in any way. When I’ve pulled just one head (the front for example), I put the flywheel timing mark on the line ( | ) in the window (the “T” line is for the rear), then check to be sure the cam gear marker is pointing up to the mark on the head, then pull the head. That way the piston is up and the valves are free so it’s easier to put the jug back on and set the timing and as long as the crank isn’t rotated. Sorry for the long answer, but hope it helps 👍. All the best ! Steve

Hi Steve, the rear cylinder's mark matches the arrow , but the front cylinder's mark is moved about 3 teeth, do you find a reason why one cylinder is right and the other nor? What would you do in my shoes?
@StevesDIYs

Hey man ! If the front cylinders arrow on the cam gear is off when the flywheel is lined up to the front cylinders timing mark, all you’ll need to do is loosen the chain tensioner to provide some slack in the timing chain then remove the cam gear and walk the chain over the cam gears teeth until it lines up. It may not be exactly pointing to the mark on the head, but if it’s within a half tooth on the cam gear that’s the best you will be able to do. Hope this helps, Steve

Hey man ! Yep, the threads are very weak on these for sure and do break easily. Fortunately Yamaha used them for quite a few motors (even as valve covers, lol) so they are still available new from places like boats.net and other powersports sites. The part number should be : 1L9-11186-00-00 and usually go for around $20usd if I remember right. If you google that part number it should pull up some websites with schematics so you can check to be sure for your year model, but I think all the years of the 750, 920, and 1100 used the same one. All the best ! Steve

Yes, I does have a single carb conversion, but I’ve never even fired this motor over as it was from a parts bike I got and have finally gathered up other parts to put another complete bike together. I was thinking to put the single carb on my bobber just to see how it does though since I have the original carbs on it now and can see just how well the single carb goes. If I swap it out, I’ll make a comparison video of the single carb vs the originals and post it up 👍

I did a lot of research on the one carb conversion. I have never found a comment in any forum or of any of my subacribers who could convince me that a one carb runs better than the original two Mikuni's or Hitachi's. The best one carb would be a Rotax which was build for supermoto racing. It costs around € 850,-... And that runs just as good as the twin carb and drivers just as much power...
