XJ650 Starting issues

Alright, looking at more stuff, it seems the "spark plug CAPS" were out of spec, but I couldn't seem to remove the inner caps. If I am understanding this, the caps are supposed to come off, right? If the inner ones are hard to remove, they could just be corroded or stuck, but a flathead and some wd40, and elbow grease should get them off?

Is there no way to check the resistance of the coils without pulling the tank off too?

Ideally for the XJ650 1982, 5k resist boots, no resist sparks?

 

Fork upgrade.
Between models there are differences in stanchion diameter. So if unsure get the triple tree also, along with brakes, wheel and discs. Big job!

Spark plug caps.
If you mean "come off the spark plug" then yes definitely.
If you mean the cap off the wire, if they are standard coils and caps, definitely yes also. If non standard then they could just be a crimp on the wire which isn't removable.

Indicator replacement with LED gear definitely drops a lot of current usage. I'm all for it.

Good luck!

 

I'll have to see when I'm over there probably next week, I'm not sure. I am sure however that they "appeared" non-removable for 2/3. The caps look like the wire went "over" the cap ends, and could be slipped out, whereas it looked the other way around for 2/3.

Not my image, but they look very similar to this:


Left is 2/3 and right is 1/4, so you have an idea what I'm talking about. The left caps don't look removable and they were pretty on there.

 

All of those are removable. You must unscrew them from the wire. The cap might be stuck a little by the waterproofing boot but they will come off.

 

Crimped are like this.

 

Cool, thank you for the context!

I've been trying to google as much as I can, to figure out as much as I can on my own, but stuff like this helps.

Wish I had a bike mechanic in the area I could be like, buy them a beer and we just futz around on the bike for an afternoon lol

 

There are a million pictures and write-ups here.
The 'diy how to' forum is super interesting.
I know I read most of them when I started this xj voyage.

 

I've certainly read those and have gone through the xj4ever catalog repeatedly learning as I go. Not the same as having someone knowledgeable next to you to soundboard things off of, unfortunately. Also, some of the how-to's here have dead image links from posters who may not be around to fix, which makes things a little trickier.

 

Yes I noticed a thread I did has dead images. Although they are there. There are policies to allow information from other sites to display which are the norm nowadays, anti spam etc. Try opening the image separately and it may be available. Right click action stuff on a computer.

 

Is it possible to convert a master cylinder that comes on the XJ to something more modern, with a detached reservoir? I have to disassemble the master cylinder anyways since something is leaking and I just assume upgrade it.

I'm trying to find a kit or...something but I am not really seeing what's good here. I don't really like the reservoir integrated with the front brake handle designs (hard to see levels with a crummy little bubble as your only visual reference, and I don't like how much space it takes up on the handle bar if I wanted to mount other stuff), but I also realize the size of the reservoir matters in order to keep things the same, for example.

Or should I just suck it up?

 

Your bike, do what makes you feel good. It is all part of making it your bike your project. I think the only thing you have to keep in mind would be the size of the MC. The plunger size of the system needs to be kept the same or very close. After that I think you can do what ever you want to do.

 

The yamaha master has a mount for the mirror if that is a concern
Also wiring for brake light just plugs in
If you can't find a good Yamaha Mc there are cheap Chinese ones plug and play
I can't vouch for them may be worth a try

 

I don't have a better photo right now, but I have this one from before I cleaned the bike of the Master Cylinder. Is this the "type A" sight window? or do I have to disassemble it in order to find out? The PDF on the parts catalogue wasn't super clear.
