Hard to add to this.

another question, is there a way to tell if a particular bike is a 2 valve or 4 valve? th bike in particular is an '89, and it seems that is the MY they changed over to 4valve. Thanks again

2v bikes had swing arm rear suspension and VIN ended in 6493001- 6494068.

4v bikes had paralever rear suspension and the VIN ended in 0040001- 0044906.

I believe that the 4v bikes had several (half dozen on the speedometer side, more on the tach side) horizontal white lines that ran across the bottom of the face of the instrument cluster.

The valve cover on the 2v is boxier and has shallow "fins" on it. The 4v valve cover is more rounded and I don't think that it has any "fins".

The 2v has dual piston front calipers.
The 4v has 4 piston front calipers.

K100RSes were 16-valve for '91-'92. Their spark plug cover says 4-valve on it. The spark plug covers are not interchangeable between the two valve cover types.

Thanks for the info, just what I needed

My 1985 K100RS had a new battery put in last year, yesterday it started right up, I moved it, then went to start it again and it wouldn't start. The starter is working and I can only try to start it about 5 times, then the battery starts to lose power, it did this last year, and after tinkering, charging and cussing, it wouldn't start. Came out the next morning .. fired right up. I am hoping the same thing will happen today, I will try to start it when I get home. I don't mess with the throttle, only the choke when starting. Any ideas? :ear

thanks.

What you see is what you get. Probably one of the most bullet proof bikes ever produced.
Figure $300-$700 for a good servicing , maybe tires and ride it like you stole it. :eat

well, a k100rs is going to be pretty hot in the deep south for much of the year. i wouldn't want to be riding mine in the summertime even in up north. That little fairing does a great job...just make sure you want it to do its job. Other than that, i love the bike. In retrospect, I wish I hadn't bought the '88 special edition. ABS system adds a lot of weight and complexity to the bike.

Good luck!

thanks.Staciebug - I'd suggest starting this in a thread of it's own. It won't get much attention buried away in a thread on another bike.

Just a suggestion..

I had a K100LT. That sucker was hot. I had a thermometer on the dash and riding in 90 degree weather the temperature behind the fairing would be 120 degrees. the RS should run a little cooler, but the left leg gets hot. I don't ride in shorts but I believe the old Ks would cause 2nd degree burns on your left calf in the summer.

I sold mine and thought long and hard about making it a naked bike. I wish I had and I would probably still be riding it. I simply could not ride it from July to Oct. Alabama is as hot as Arkansas.

My $0.02.

Interesting comments about the heat on the RS. I have had nothing but RSs with about 250,000 amongst them riding in the central valley of CA at all times of the year. Not as humid as Arkansas or Alabama by any means, but 110 is 110. If I ever rode them in jeans, I was uncomforatable on any of them. I got heat rash on the backs of both calves riding an hour in the heat in jeans on my 1100, and 'sun-burned' the inside of my thigh on my 100 when I wore slacks - once. But with full gear of either leather or a 'Stitch, the bike heat was not a problem. I would say it depends greatly on the type of riding you do, how fast, stop and go, in traffic or not, etc. The RS is a great all around Road bike for sport oriented and touring type riding.
