Thank you for the info. As suggested the seal behind the advance unit was leaking. Replaced it with the one off my parts bike. The seal was hard and warn. The one on my parts bike was soft and plyable and fit tighter. Oil leak solved. Last thing on my list of things to do is a carb sync. I'm...

So I finally got the bike going and took it for its first 10 min ride. All went well or so I thought. When I got home I notice the right half of the bike has oil on it. Removed the timing advance cover to find an oil pool at the bottom. Do the 2 holes in the pics need to be sealed or do I have...

I did not reLly have a price in mind. I kind of was waiting to see what people thought. Is that ok or does it have to have a price

I have front forks and matching front and back wheels from a gpz600r that I have made to fit a xs650. I took the stem from the 650 and welded it into the triple clamp of the gpz600. I have decided to abandon the project because the motor is to far gone but I will sell the front fork set up and...

Thanks for the good feedback. I like the tuning forks as well. My buddy at work tried to convinceme to put a hamster running on a wheel on it.

I see in the diagram there is a washer I looked high and low for it. It's not in sump, not in the filter, and not in the side cover anywhere. Is there anywhere else to look. It is possible the previous owner removed it and did not put it back judging by other things I have found. The bolt that...

So I found 2 long plastic pieces in the sump when I removed it to clean. I think I will pull the engine before riding season and fix it but I am confused. There are 2 cam chain guides. One front and one in the back. I Want to order what I need before the job. Do I need both or does only one...

I got my oil filter laser marked with the Yamaha emblem. What do you guys think?

Removed the clutch side cover and all looks ok. The issue was the previous owner removed the bolt that holds the tach cable connector to the engine. That rode up which caused the geared post to come out of the hole in the bottom. Put it all back together. While inspecting I found pieces of what...

I tried loosening the timing chain just a smidge and fired her up again and I found that what was causing the click was the tach where it goes into the engine housing. The mounting point is broken maybe because I grabbed the wire and with no effort it slid out and the tapping stopped.

I have been slowly getting my 1979 xs650 ready for spring. My latest project was updating to the one piece push rod with a new bushing and seal. I started it up to look for leaks and all was good started with one kick in 25 degrees. Ran for about 10 seconds I turned off the choke and it kept...

Ok thank you all again for the advice. I will order up a set of unipods for her and plan to jet up one size and see where that gets me. Might come back to this idea eventually though because I think it's an interesting possibility.

Ok. Thank you for the input. The thought was I could make adjustments with the whole thing still on the bike. So make a small adjustment then take it out for a spin. I thought might be able to dial in the mix by adjusting the air resistance. Maybe I will just try getting the unifilters and see...

Wow with unifilters you did not have to re jet? Do you have a suggested part number from them

Well a stock air box does not adjust its air through the rpm range. It just supplies air at a constant draw. My thought is to match the air inlet of a stock air box with a new style filter. My stock box was missing a few pieces so it was unusable. I am just trying to match the stock air box...

I have been working on my 1979 xs650 and have it starting great. But since I had to do away with the trashed stock air box I tried to use pod filters. I was having issues with a very lean mix. Stalling when I try and blip the throttle. So I came up with this idea. Can anyone think of a reason it...

Thank you for the advice. As suggested I took apart the timing advance set up. It was missing the inner pin that keeps the cam shaft and the timing rod in sync. I measured the proper size and length pin and made one up. Reassembled the whole thing and it started right up. The advance fingers and...

Ok it looks like there are teeth on the inner plate that let you hit it until it's tight. If I inspect it and all looks good should I just put it back on and tap it till its tight?. Will this all effect the timing? I think it must because the points side was free spinning

Did a little more tinkering. Here is somthing wierd, I turned the timing advanced side clockwise about 3 turns and it tightened up. Now it's all turning together but I'm guessing my timing is now way off. It does look like the pins are installed in the key ways
