Spark Plug Question

[Hawk]

I went to local BMW dealer to get 4 plugs for 2004 R1150R. They sold me 4 NGK R plugs, all BKR7EKC. I asked about that and they said BMW now specs the same plugs for upper and lower.

Anyone have any experience with this?

Thx!

Well I'm glad you broached the subject because I had heard they needed to be one interval apart with regard to "hotness"...like a BKR6...this could ignite the atmosphere!

Before I got started changing fluids and plugs I went to the local Kawasaki dealer (close to me) and bought 2 NGK DCPR 8 EKC plugs per the Clymer manual. Good thing I did. When I pulled the secondary plugs (they were the Bosch YR 6 LDE), they were a smaller diameter than the primary plugs.

Bike runs fine, parts guy at the local BMW dealer is an idiot!

Here is what my parts guy told me to buy... guess NGK is primary, Bosch is secondary

Thanks Rick, good to have the BMW part #.

Clymer manual indicates wrongly for the secondary plug.
It is mistaken.

The correct NGK plug for secondary is NGK DCPR6E .
I used to use NGK IRIDIUM DCPR7EIX, but the were fouled, they are too cold.
When changed to DCPR6E things went perfect.
Other people think like me.
Be aware, try it yourself.

Parts guy is probably fairly new and doesn't realise that R1200 engines had predecessors.....

i like to support the local dealer but they are 45 minutes away with good traffic and charge top $$ for their stuff.
here is where my routine parts come from;
