dajogejr Posted July 6, 2006 Report Share Posted July 6, 2006 This is a guideline only... With the air lid on, 250 mains. With the lid off, 280 mains. We need more info... My estimates are at or near sea level (less than 1000 ft.) and 65 to 90 degree riding temps. Do yourself a favor, ditch that boost bottle. It's taking up room...and that's about it.

apbt549 Posted July 6, 2006 Report Share Posted July 6, 2006 i would leave the air box lid off make sure you have a pro flow intake.and like dajogejr said 280 on the mains is a good place to start. but your riding temp and elevation is also needed.....

liquedfire Posted July 6, 2006 Author Report Share Posted July 6, 2006 kool thanks i live in ottawa so id say about 1000 feet above sea level and around 20-35 degres temp thanks again Quote Link to comment Share on other sites More sharing options...
dajogejr Posted July 6, 2006 Report Share Posted July 6, 2006 That's 25 to 30 celcius....right? That's 75 to 90 or so....Farenheit... And, ap is right. You can not leave the air box lid off without a proflow adapter...the bottom side of the lid actually secures the airfilter tight against the front of the box and seals it. Without an adapter, the air filter will just bounce around... Quote Link to comment Share on other sites More sharing options...
liquedfire Posted July 6, 2006 Author Report Share Posted July 6, 2006 yup your gight so could i drill some holes in the airboxlid???? Quote Link to comment Share on other sites More sharing options...
dajogejr Posted July 6, 2006 Report Share Posted July 6, 2006 (edited) Yep...sure can, and many do. You can even remove almost the whole survace, and they make an outerwear to go over it to keep the big stuff out. Figure from 1 to 3 sizes larger on the main, might have to turn in the air screw 1/2 a turn as well. Edited July 6, 2006 by dajogejr Quote Link to comment Share on other sites More sharing options...
liquedfire Posted July 14, 2006 Author Report Share Posted July 14, 2006 (edited) k so i got 270 in it now and the plug is white (lean) so i was wondering how much bigger i need 2 go????? Edited July 14, 2006 by liquedfire Quote Link to comment Share on other sites More sharing options...
dajogejr Posted July 14, 2006 Report Share Posted July 14, 2006 No way we can tell you for sure. 300 would be safer... Now...are you just reading the tips of the plugs, or actually doing a plug chop? A new plug can take a little while before the insulator nose starts to color. However...by doing a plug chop properly (involves a grinder or hack saw) you should get a light chocolate 2mm ring around the base of the porcelin. Gotta be honest, though...with an airbox and no lid, 300 is usually a little rich. 270 to 280 is the norm.... Quote Link to comment Share on other sites More sharing options...
