just picked up a 94 K75s. Radiator question
« on: September 04, 2024, 10:16:32 AM »
I just started at a new school and during lunch I noticed an S for pretty cheap while looking on CL.  Price was low as it wasn't running, but I went to check it anyway.  A local shop was closing up and this bike had been knocked over by a truck, so it has some fairing issues on the right side.  After some chatting and the owner grabbing a jumper battery, the bike started up and ran smooth, but we noticed the radiator had cracked near an inlet on the right hand side.  He was cool enough to put it in the back of his van and deliver to my house, super lucky.  30k miles, a stack of receipts, maybe 2k miles on the tires, the oil is still golden and the seat is nicer and comfier than the one on my K75RT.  I was originally going to buy it for parts, but now I think it may be a minor project that will keep me cool during the hot days.  I was surprised at how much lighter it feels than my RT. 

With regard to the radiator, I am going to try to fix the crack prior to ordering another one, unless someone can convince me that it is a fools errand.  The crack is at an inlet right wear it meets the body of the radiator.

Sounds like a find, I'd try fixing the crack if it works you're good if not nothing lost.  Couple RT's I've ridden really made me appreciate my S.

Fools errand?  It’s nearly half of the inlet.

I say go for it! You've lost nothing but a bit of time if it doesn't work.
