:stupid it depends...... go hold ur throttle in a certain spot for a couple mins(i.e. 1/4 throttle, 3/4 throttle or w/e ) and if its black then that setting is rich.... if its like nuthing, its lean... thats the only way u can really tellOriginally posted by YFZ@Feb 12 2004, 10:33 PM
I think it depends. You could be rich anywhere in the powerband. Are you running rich on the top end can you tell?
that sounds good........ i dnt know where ud be messed up...... maybe 3rd clip on needle? :what let one of the gurus tell u :rockOriginally posted by tmm403@Feb 12 2004, 11:05 PM
i have a hmf full exhaust,cam mod,lum airbox no lod,and i have right now a 175main,48pilot,gyt-r needle 4th clip,2 turns. this is the setting that makes my sparkplug black. i was thinking of switching to a 168 main but is this the only thing i have to change????????????? also i am at sea level and the temp is about 30 or 40 outside
That is not how you do a plug chop.Originally posted by tmm403@Feb 13 2004, 04:11 AM
well with the 175 main i have in there now i was just going up and down my street and up nand down my driveway thats it. i did before try a 170 main and it was black also. i will try the 170 again and see if that helps but mainly all i was doing was rolling the gas and then gunning it. like you would do to try to get the front end up. it just sucks b/c from all this jetting changes i already used like 6 plugs. alright i hope this sloves my problem.
I think you are worrying about the plug too much. If you jetted it and it ran awesome it will be all right. As long as you are not too rich that you are fouling plugs just leave the jetting to when it runs awesome. I am not a mechanic or know much about engines I just started jetting so if anyone disagrees let him know. I just think you should jet it to when it runs awesome and leave it alone. Do not worry about the plug. It is very hard to get the plug to be brown meaning absolute perfect jetting.Originally posted by tmm403@Feb 13 2004, 10:48 AM
OK what i did was first i tried a 170 main,45 pilot,2 turns,clip 4 gyt-r needle. that made the sparkplug black. next: 180 main,45 pilot,11/4 turns,clip 4. thats when i did the full throttle test. very good but a little boggy when i first hit the throttle. so maybe that was the airscrew casuing the bog. and that when my sparkplug was white when riding and then black later on. then i thought i would try a 180 main,50 pilot,2 turns,clip 4. same thing sparkplug white but when i gave it throttle it bogged. my guess it was the pilot to big. so then i went back to when it ran good with little bogging and try to go from there. and also after i tried it with a 170 main the sparkplug was white when doing the test but again black later on. and this last jetting i did was 175 main 48 pilot 2 turns clip 4 and it ran awesome except for the damn plug. so please tell me what i'm doing wrong from all of this.
