TO BE OR NOT TO BE

OK HERE US MY QUESTION: SHOULD I FIX MY 82 XJ750 MAXIM ENGINE, NEEDS STARTER, STARTER CHAIN AND GUIDE AND WHO KNOWS WHAT ELSE.

OR SHOULD I BUY A LKQ 1982 SECA ENGINE WITH STARTER AND 30 000 ODD MILES BUT RUNNING FINE.

SO SHOULD I CRACK HER OPEN AND REPAIR AND GET A MANUAL

OR JUST DROP IN A SECA ENGINE INTO MY MAXIM??

 

The seca motor and the XJ motor have different mounts. You need to swap the mounts also. Seca hard mounts XJ rubber mounts. I guess its a matter of whats cheaper and easier for you to do.

 

CHEAPER MIGHT BE REBUILD BUT I NEVER DONE IT BEFORE SO IM A LITTLE CLUELESS ON HOW TO BUT WOULD LOVE TO DO IT.

ENGINE WOULD BE EASIER DROP AND GO I SUPPOSE I LOVE THIS BIKE AND I DONT WANT TO SEE IT SIT THIS IS MY FIRST BUILD AND WHAT I HAVE IN MIND I HOPE COMES OUT IN THE BIKE.

 

If the swap is doable then do it, then while the engine is out start the rebuild process. It may take a month or a year depending on time constraints, place to work on it and the ever elusive $$$$$$$.
In the end though, you will have a daily runner and a rebuilt motor ready to go. Plus, when you go to put the original back in you can sell the Seca motor and possibly recover some of your costs.
Just a thought.

 

I LIKE THAT THOUGHT THEN NO RUSH TO SEE HER RUNNING AGAIN.

THANKS ALOT THIS ALL REALLY HELPS IM A NEWBIE SO I CAN USE ALL THE INPUT I HOPE THIS WILL COME OUT GOOD ILL POST PICS TO GET INPUT ON WHERE TO GO ON THING SHE IS A LITTLE ROUGH BUT STILL MY BIKE

 

Since you've asked this in at least two other threads, I'll summarize:

You CAN rebuild your existing motor; and if the top end is in good shape you don't even need to tear into the top to fix the chain guide and starter clutch.

But it IS quite a job for a new mechanic.

The engine swap, while having quite a bit to it, would actually be easier and cheaper, provided you're not just installing another dying mill. Be sure the "new" motor gives good compression numbers or don't buy it.

Besides motor mounts, there are shifter considerations when swapping between Seca and Maxim motors. This was explained in one of the other threads.

 

COOL THANKS IM NEW AT THIS SO IM TRYIN NOT TO MAKE ANY MAJOR MISTAKES AND MAKE MY MIND UP SORRY FOR THE POST

 

NOW I AM ON THE HUNT FOR A GOOD ENGINE THEN

 

No worries.

However, pay attention to what we're telling you. You do not want to buy into another big engine repair job; you can afford to "shop around."

DO A COMPRESSION TEST on any potential "candidate." If the motor makes good numbers, you're reasonably assured that you won't have any major issues. You'll still need to do things like adjust the valves, etc., that you would have had to do to the other motor anyway.

KEEP ONE THING IN MIND.

ALL shaft-driven XJs have the potential for the chain guide to disintegrate. For some reason, it never happens on some bikes; but it happens frequently enough to be considered a "common problem." And mileage apparently makes little or no difference, although it does seem to appear more frequently on bikes with more than 20K miles on them.

Find a solid, low mileage motor with good compression. Be picky.

 

ok i will shop around and find one with low miles iw ill also have or do a compression test before i buy any engine thank for the help
