Hello from PL

[Belzebud]

Hi, I've got a KJ 2.4. It was quite fun and never failed. Now it's starting to shout the age and 350k.
I hope I'll get a clearer idea what to do with it. Rebuild the engine and trans (maybe switch to NSG370?) or been done with it and get a Yaris, save up and buy a newer fancier all electronics imitation of a SUV..
Glad I found the forum

Welcome to the forum.
What year is your in line 4 cylinder ?
Could you re-build the engine yourself?

It's a 2002.
I'd love to rebuild it (I'm working slowly on my XTZ 750), but I don't have much spare time or the space. So I'd have to get somebody to work on it.

Who ever does work on it will need the 2002 FSM so here it is. https://colorado4wheel.com/manuals/Jeep/KJ/2002JeepKJServiceManual.pdf
I'm currently working on my CB650 4cyl should have it ready in 2 weeks.

Thanks, found it while doing my initial forum search
The big question how far gone is the engine?

What year is the CB?

350,000 Is a lot of miles! Bearings, rings, boring or liner replacement, pistons, timing chain, valves, cam bearings... Are there replaceable cam bearings?

What about a rebuilt engine; or junkyard. Swap & go!

Tearing it down for a rebuild is fun fun fun, yes sometimes it's easier to do a complete swap.
Jasper engines is the best way to go. They rebuild with upgraded & quality parts!
Then you are good to go for many years & miles ahead.

My bike is not stock by any means.

Well it's km not miles, I had the 300k km mark in my head from the last MOT check. Did one last week and currently 222k miles, 357k km.
You touched the big question if it is reasonably doable?
Rebuilt engines in PL don't really exist. Used engines are rather a lottery with little chances of success.

Is it possible to switch the 2.4L to the 3.7? If I understood correctly the transmissions have the same mounting bolts, would kind of like to stay with the manual.
Swapping for the 3.7 would be great, as they're easier to find and replacement parts are much more accessible.

Rebuild/swap would be fun, but for that I'd need to do it myself and that's not an option for now.
Jasper don't ship to EU from what I see...
