Correct spark plug for 85 250 SX ?

[ric44]

Had the bike tuned not 6 mos ago and the plug has already gave up. I think the mechanic just stuck what he had in it. Put the old plug back in it fired right off. Plug i took out was NGK DPR7EA is this right? The old one has a different number. Thanks guys.

I think the correct one is the NGK D7EA. I use it in all my 200-250 trikes.
