Hello all,

I'm doing winter maintenance on my '93 K1100LT and I have a question about spark plugs. Last summer I bought seven Bosch X5DC spark plugs, three for my K75 and four for the K1100. Unfortunately, I now see the correct plugs for the K1100 is XR5DC. I understand the "R" means it is a resistor plugs.

My question is, can I use the X5DC plugs or should I buy XR5DC plugs?

Thanks for your help.
