Gonna be soon Ralph. I just got all the wire and connectors for the heavy battery, starter & solenoid terminals. I've got the lower fuel tank and new fuel lines installed and I found a gas station that sells non-ethanol gasoline. She's getting close...

I have a xv750 83 but the clutch is basically the same but I have replaced the friction plates and adjusted the free play on the lever like you. But my problem is that I get a grinding noise when the bike is in gear. Do you know what might cause that?

Have a look at the throw out bearing - that small but precise flat looking bearing that the rod pushes up against right before the outer plate. Depend on where the noise is coming from (deep inside the engine, left side, right side, etc) it could be a number of things. If it's coming from the clutch side then it could be that bearing or the nut holding the basket on the main shaft.

Are those friction plates still wet with oil while you putting them back in? At end of push rod, which you pulled out and pushed back in, isn't there supposed be a ball somewhere.

Yes, the friction plates have been soaking in motor oil for a few hours before installation. I took them right out of the bag they were soaking in and put them straight on the clutch basket. For the pushrod, most have a ball somewhere in the system to allow for spinning of that long pushrod. In this model year, the clutch is cable type operating a cam on the left hand side. The cam bracket assembly (where the clutch cable connects) has the ball on that part so it doesn't come out with the clutch on the right side like so many other motorcycles do.

@@KensWorldRestorations Thanks, I am just preparing myself to start working on my 82' XV750 clutch plates and push rod.

Hi, On the clutch push rod, at both end there are small added extensions, both with threads. I found both ends are loose and rotating free even after having threads on both ends. Should they be free wheeling or should they be tight? I am working on 82' XV750 Virago clutch. Thanks.

Hi…I’m not 100% sure about the ‘82 750. But on my bike, the left side of the pushrod is a threaded end with a locknut. That’s the clutch adjustment cam and yeah, it definitely has to be set properly and tight. I don’t have the ‘82 shop manual available right now (I’m away at work). The right side on mine just pushes on the thrust bearing on the clutch plates so it’s not threaded.

​@@KensWorldRestorations I think it's deferent set up you got there. The push rod I got does exact the same, it pushes the clutch plates. When I opened the left side cover, the rod was visible and if pushed in it would bounce back, however i did rotated it to check and I also pulled it out easily but it came without other end the of the small nut so I inserted back. Since I am rebuilding clutch basket I manage to retrieve the missing end of the rod. Now I am wondering if the threads got worn out since I am unable to tighten. It keeps rotating.

@@mcrand7887 Crap...not sure if I'm going to be able to help you. Have a look at the shop manual if you have it or go to CMSNL (or any other parts place) where you can look at an exploded assembly diagram. That's about all I can think of at this time. Sorry, but I don't have any experience on the GEN 1 Viragos.

I wonder about an issue, why the Virago's front cylinder oil spitting/baffle tube is join to carburetor rubber boots? it's not a air inlet, it spits extra oil coming from cam chain which will end up in carburetor that will mix with gas and burn and create smoke, beside it also makes rubber boots and frame oily and sticky from the inside. And why it is only on front cylinder and not rare? Can anybody explain this? Thanks.

It’s a vacuum line. Depending on the year of your bike, it either goes to the boost sensor & the valve on the left side “air box” or it goes to the AIS unit (or a combination of these places). It’s used to sense vacuum and that vacuum is converted to a signal the TCI unit can use to control timing. The reason why there’s only one is that the two cylinders are jetted differently in order to help with cooling the rear cylinder. That vacuum line has to be in place if you have a boost sensor and the sensor must be functioning or the entire system won’t work properly and you’ll get backfiring and all sorts of other ignition related problems.

@@KensWorldRestorations My XV750 is first gen. 1982. I had to rebuilt HSC40 carbs and replaced all jets recently, however the new jets are not numbered and they are all the same for front and rare.There is one air inlet right behind rare cylinder on chassis must be to connect rare baffle so I had to cover it.

@@mcrand7887 Yes, I forgot to mention that the rear cylinder tube is supposed to be capped off. It is not used for anything except when doing a carburetor balance. As for your jetting, it’s not critical and should actually be set depending on your specific altitude and performance. These points I mentioned above are for when Yamaha motorcycles left the factory in order to meet country-specific emissions regulations.
