I run the NGK plugs. I replace them around every 20k to 25k. They are cheap, good quality, and readily available at O'Reilly Auto. I paid about 1.60 a plug for just the V-power TR-55 (stock no. 3951).
If you run nitrous or a hot heads and cam setup try the TR6 (stock no. 4177).

NGK. I have said it before and I will say it again, NGK is the only spark plug that has survived in my motocross bike for multiple motos. 2 or 4 stroke. Thats 12500 rpm give or take. I am a believer.

I tried bosche fusion plugs (4 ground straps)about 6 months ago wrote a thread about their performance in a nutshell, basically the problem with these plugs as there are four ground straps that run parallel to the porcelain insulator, and as such the spark is supposed to jump to one of the ground straps but what happened was the spark over a period of time,carbon tracked down the porcelain insulator so instead of the spark occuring at the tip of the spark plug it was occuring deeper inside the plug causing stumbling and rough idle. They sounded good on paper and I thought they would work fine I had posted my intentions and got a face full of s#*t most said they were snake oil and or a gimmick and guess what they were right ...stick with delcos or NGK everybody can't be wrong
