What the ?....

[ColoNat]

Changed plugs last night and put in the new Moose equivalent to the DPR8s... took a look at what i pulled out and they were DPR7s?! :ummm:
Why would someone put the 7s in place of the 8s?

(Just got the bike... no clue how long they've been in there)

It must have taken a long time to warm up hence the reason for the hotter plug.
When you advance the ignition you would want to run a colder plug.
