The petronix made a big differenc for me. I however added the MSD 6A and their coil.

For the money you are not going to see a big gain out of the Bosch plugs. For my Harley they come in at about 1 horsepower over the stock plugs. I would still use a platinum, just so you do not have to mess with plugs very often.

 

Back on the topic of plugs the ngk plugs are the only plugs I run in my fourwheeler and they work great.
oh ya had a 0.137 light Friday night 0.0 is perfect so I was just about there, the banshee ran 77.7 mph at 15.3 sec 1/4mile :P

 

That's a very quick 4 wheeler, Shaun. No wonder your hair is all slicked back.

 

haha, it's not slicked back it's just real real short....
It used to run in the mid 80s like 86-87mph but I changed out the reeds and retuned and Re-jetted it. I lost alot of top end speed
BUT I gained huge in the bottom, like cut my 330 ft and 1/8 time almost in half

 

Interesting sport. You ever take that puppy out in the woods, or is it strickly a street bike/4 wheeler?

 

I ride any and everywhere I can... drag strips, alleys, fields, woods, dirt roads but I really love the dunes Slap on the paddles

My dune crew We try to meet up a few times a year, guys from everywhere TX, OK, KS, MS, Neb we all meet in Waynoka, OK to ride the dunes there

Me and the girl infront of the sign to the dunes

Well, I envy you for your sport. It looks like a lot of fun. But, we are getting completely off topic here, so I guess we need to stop the 4 wheeler conversation.

 

(grin)
sorry

 

Not a problem, I just have a job to do, in that we need to stay on topic as much as we can.
On edit: I am more to blame for being off topic than you. I asked the question, didn't I? I think it is important that we members here get to know each other and our other interests, but still try to stay on topic as much as possible. I have been on other sites where these kind of conversations get out of hand very rapidly, so I just want to keep us friendly here on this forum.
