No Idea

I very much understand your frustration. If you have a place to store it, my advice is to make a record of what you have done up to this point, park it and walk away for a few days, weeks, or even months if you have to. Way too nice of a bike with a lot of tender love and care put into it for it to go down the road. Everyone has to do what they have to do for their situation so no one will fault you for that

 

Well I didnt give up. Took a closer look at timing. It was off 1 tooth on intake and possibly one tooth on exhust.

Would that make my compression low .And give me a bog down low.

Rechecking compression .Tonight now that its in time.

 

YES if you are off one tooth the valves are not in sequence which would lower compression .

 

Not sure how much you've invested financially, or time-wise and do not need to know. However, it may not be too late to consider other options.

Rationale: 1. Money Invested into solution w/o guarantee of fix 2. time 3. You've still got some form of liquid in your current engine's oil (compounded problem - timing off, some form of leak, ect.) 4. Keeping Maxine in your position

Possible solution: donor bike, or donor engine. Would give you the opportunity to perform proper benchwork on your current engine at a later date, and get you back up-and-running without too much investment AND a guaranteed solution. Hopefully long enough to get the original(?) engine repaired.

Just a thought from a fellow-fanatic.

Cheers mate,

 

I'm quite certain the the fluid in the oil is condensation.
Reason to believe this is. No loss of coolant. And the weather here has been rediclous all winter. Warm cold warm cold warm cold. Its been up to +12 and down to -20 in same day . and this has happened all winter.
The head has never been off the bike. And for a gasket to go I can't see compression being fairly even across the 4.
Dont get me wrong I'm no mechanic. But I'm crossing my fingers for it being out of time and condensation.
The bike works to well for other serious stuff.

 

Well the timing was off 1 tooth on the intake and 1 tooth off on the exhaust.

All timed up now and a cold compression test was 149 across all 4.

I hope that's solves my frustration lol.

 

when you get it fired up run about an ounce of seafoam in the oil to clean out the crankcase

 

Yes indeed. Picked up new filter, I'm ready

 

So with all thats done to my bike. It still starts hard when its warm after sitting for 5 minutes or longer .
Everything is to spec. I even tried priming it for a few seconds but still needs a touch of the throttle.
Any ideas?

 

Enricher (the choke that's not a choke)?

 

Works normal.

 

Seems like a fairly common characteristic of the XJ. I don't really recall anyone saying they solved this - just suggestions like trying prime that you already tried. I know I have the same issue, and I just crack the throttle open slightly as you suggested, which implies an over rich condition is occurring.
