Running power Yamaha xj600 diversion

Moin together, I just recently made my phone card with 33J, sorry, and I think about whether I should buy the above machine. I had borrowed various moppeds so far and with the diversion I got the best clear at almost 1.90m, especially since this is still used relatively cheap. I have an offer about a 94 XJN with 35tkm for 1600€ available, which worries me if this is not already too many kilometers, in terms of durability. still buy or do I have to expect the engine or something to give up after a few kilometers? What are your experiences/opinions?
