Ok so i have a 2004 rev it calls for br9ecs 0.5. I bought br9ecs-5 plugs but it runs like crap. I put in br9ecs plug which are suppose to fit sdi models it runs good. What are the proper plugs? or should i say what is the proper gap?

Anywhere the snow is deep, and the hills are steep
the only difference between br9ecs and br9ecs5 is that the br9ecs5's come pre-gapped from the factory. Absolutely identical spark plug, but the non "5" are left for you to gap. Either you have the gap way off, or there is something else wrong. I can't recall if the 800HO and the 800R have the same gap, but I know the factory "calls" for .030 gap. Which I find a tad bit wide. I run mine tighter than that.....

I found a great plug site in my long search, i have order some plugs from them... clubplug.ca 2004 needs br9ecs with 6669 on the top of the box. It is not recommended to gap these plugs so you have to order the right gap. Or Br9ecs-5 which i did order but seem to run rough.
