Bike Bandit and my Service Manual list a few different spark plugs for my 300. does anyone know which is the best one to use? I'm sure they are just different heat ranges. The riding I do is pretty inconsistent, I could be down the road top speed one day and the next day alot of slow moving and idling. Here are the plugs it lists.


SPARK PLUG (DR7ES)
(DR7ES) (NGK)


SPARK PLUG (DR8ES)

SPARK PLUG (DPR8EA-9)

Also I am going to be going through the carb HOPEFULLY this weekend (didn't get to it last weekend) and adding one size bigger fast jet if that will make a difference.

I've always used the DR8ES and I've never had any problems. I believe that's the one that comes in them when you buy them new. I've never really tried the others, though.

DPR8EA-9 is what I ordered last time for some reason, according to my bike bandit order history, so I ordered two more of them. I guess they will be fine.

Yeah, they should be fine.

My AMSOIL book lists DPR8EA-9 as the standard plug and DPR8EIX-9 as the premium plug.

Great thanks for the info the standard plug is what I ordered but for some reason they haven't shipped yet. My tire has shipped though! Bike Bandit is usually pretty fast at getting your stuff out not sure what the hold up is on two spark plugs.

No kidding, oh well, not like I need it today, but my tire will be here tomorrow, finally I'll have matching front tires! and it won't handle so funny anymore LOL.

That is if UPS can get their truck to the house, supposed to rain all day tomorrow road turns to crap pretty fast. I love living in the middle of nowhere.
