lms1977 Posted August 8, 2011 Report Posted August 8, 2011 I built a new 465 serval and it runs awesome until i start climbing a hill and let off the throttle and get back on it. It will just bog even if I down shift. If I am on a flat surface and hit it, it's almost to fast if I am in a gear to high and hit it it sounds like it breaks up and smoke alot then clears out and runs awesome I dropped the needles all the way 34mm mikuni flat slides is whats on it for now with shearer inframes. when I say hill were talking little hills you could drive a stock truck on. If I give full throttle when it bogs it comes back to life. Some one up where we ride told me to try pods I currently have a single k&n on it and it was clean and I took the outer wear off it did the same thing. thanks Mike Quote

coryv4 Posted August 8, 2011 Report Posted August 8, 2011 Hey said 34mm...haha lol i just skimmed across it i think the main might be rich or 2 short of filters not getting enough air? Quote
lms1977 Posted August 8, 2011 Author Report Posted August 8, 2011 I played with the mains from 300 to 280 did not change the problem lugs look nice with the 290's in it. Quote
coryv4 Posted August 8, 2011 Report Posted August 8, 2011 I played with the mains from 300 to 280 did not change the problem lugs look nice with the 290's in it. maybe its just gearing i mean any bike will bog with to high of gearing Quote
lms1977 Posted August 8, 2011 Author Report Posted August 8, 2011 I'm running the same gearing I ran with the old motor 13/41 I need to run taller gearing. Quote
dirtydownunder Posted August 8, 2011 Report Posted August 8, 2011 have you checked the plug caps ? or other ignition parts ?. 290 is pretty lean, whats your elevation ? Quote
lms1977 Posted August 9, 2011 Author Report Posted August 9, 2011 Both cyl get great spark. I thought it should have bigger jets also. I will have to look into how to check the ignition parts. Quote
dirtydownunder Posted August 9, 2011 Report Posted August 9, 2011 having great spark doesnt mean you have great spark under load. 1 Quote
guns4children Posted August 9, 2011 Report Posted August 9, 2011 I say give up and trade me engines Quote
lms1977 Posted August 9, 2011 Author Report Posted August 9, 2011 (edited) I will try pods hopefully today. I cleaned all the oil off the k&n and put it back on tried it this morning seems like it might be a little better but it might be me being wishful. I gave the plug caps one more turn and checked that the plugs snap in that all seems good? What else should I check and how to check if its not obvious? Edited August 9, 2011 by lms1977 Quote
