i need a little help on dialing my sxr in. i have been busy all summer and i am just getting the time to get it set up.
83mm bore with minor porting
185psi compression
6 degree timing advance
dry pipe
taper bored 46mm mikunis
v force 2's with r&d intake mani
jets are 110 mains 125 lows
23psi pop off
my problem is when i cruise the boat at say anywhere from 3/16 to 1/2 throttle the boat loads up pretty bad and blubbers like a school girl trying to chug a beer. on topend wide open runs the plugs are golden brown. i have tried leaning out the low speed both with changing jets and playing with the screws....randy from watcon suggested that my high speeds are to big and they are dumping fuel in when cruising. but i tried leaning the highs out and still nothing has really helped. (although i have not put much time into this yet). also i have no clue why it would make a difference but the loading up/blubbering is worse when it has a full tank of fuel....when the ski gets below half tank it runs better. tomorrow i am gonna try some more jetting combos because i have some time. anyone have any alternate starting jetting specs? someone a while ago suggested something like a 130 high and maybe a 105 or so low? thanks
