83 XJ 750 questions

I just acquired a 83 XJ 750 from a co-worker that has sat up for over a year. He gave me the bike because the engine was locked up but I took the plugs out and sprayed each cylinder with PB Blast and got it free by putting it in 3rd and rocking it back and forth. Today I sorted out a no spark issue and actually got it to fire off. One problem I did run into was one of the plugs was cross threaded into the head and the other is these stupid pull back handle bars. For the plug, should I keep my eyes our for another head or is there another option I can do? For the bars, I would like a straighter set but the issue will be the weird angle the mirror mounts as well as master cylinder will be in. Is there another bike I can get these parts that will work on the XJ? Thank you in advance.

 

You could do a helicoil for the spark plug

 

A thread chaser is another thing you can try or as Wgul suggested a heli coil kit..Oreilly or Autozone or NAPA .

 

A Heli-coil can be done with head in place just use a large wad of grease on the cutting tool to trap aluminum shavings.

 

seca 650 bars are flatter, dual disc so the mc should work for you

emgo has a catalog you can download and see different bars.

If you switch to flatter bars, you'll need to switch to mirror mounts/MC that are for flatter bars. Otherwise, you'll have that "odd-angle" thing going on

 

Thanks to all for their input.

 

...and that dangerous brakes situation.

 

You mean the extreme angle that the MC would be in? Is brake fluid REALLY needed for the brakes to work?

 

nope but you will wear out your boots faster with out brake fluid.

 

Just call me Fred Flintstone.

 

YabadabaaDOOOON'T!

 

I have a question that I trust is relevant to the topic. Have acquired a XJ750RL, 1984 model, that I am restoring from a few boxes of parts. The fuel system is spagetti - 4 Vac hoses and 3 fuel hoses from carbs, but only one each from tank. And so far web searches are not helping. Do I need some small manifold fitting? See pic. Vac hoses at top, fuel below.

 

- The four top ones are vent tubes
- The two middle ones are overflow tubes
- The low one in the center is your fuel supply tube from the petcock

Could you also please send me a conversation....I'd like to get a little bit of info so I can register your 750rl on the addendum to the 900rk registry.

Thanks,
