01bansheeke Posted October 4, 2004 Report Share Posted October 4, 2004 I thought i had 390's in my shee..but they were actually 360's. anyway... I jumped up to 390's from 360's on my shee after i added the pipes. I put new plugs in..the plugs look like cardboard. Which from my understanding is pretty close to dead on. My question... When i lay into it..assuming i am in the right gear..it starts to pull hard..then it has a slight sputter like it wants to keep pulling, but its just not happening. It pulls hard to a point, but most of the way up to it, it has a slight sputter. however, it feels like there is more left in the pipe like it wants to keep pulling. I am happy with the way the pipes feel..but i know its not quite right and it has much more in it. Air intake is definitely my next mod...rev it up with the seat off and the filter sucks in hard..anybody got any spare air I can ram in there lol Do i need to jump up to a 410 (do they make a 400?)..scew with the air/fuel screw, move the needle up or down? where do i go from here.

sredish Posted October 4, 2004 Report Share Posted October 4, 2004 If it's a sputtery drowning feel and not flat bogging, then you might be a tad rich on the main. You could try 380s and see if it clears. But you have to make that call. Reading the plugs is key. Up inside the porcelain, there should be a ring that's dark chocolate colored. You also want the base ring and ground strap to have a dark brownish color. You can do a plug chop to really see how the ring looks. Just do a search on plug chop.

You can see in the plug with a flashlight too. A magnifying glass is helpful. Edited October 4, 2004 by fixitrod Quote Link to comment Share on other sites More sharing options...
01bansheeke Posted October 4, 2004 Author Report Share Posted October 4, 2004 they do have a slight chocolate color..I'm going to try a 380 and check em again. After that, i'll start in on the needle. Quote Link to comment Share on other sites More sharing options...
sredish Posted October 4, 2004 Report Share Posted October 4, 2004 Yeah, I usually just use a flashlight or the sunshine. I pretty much never chop my plugs, really no reason to, if you now what your looking for. Cool, let us know how it works out. Quote Link to comment Share on other sites More sharing options...
