ezuniga21 Posted March 12, 2018 Report Share Posted March 12, 2018 I have a 2000 Banshee with full port cylinders, light flywheel, adjustable timing plate, cool head, vforce3 reeds, 35mm keihin carbs, and override transmission 2-5..... I recently did a tune up went from 91 octane to 110 (oil ratio 40:1,) also went from NGK(BR9ES) to NGK(BR8EG) cause someone told me to run it on hotter plugs, another thing is I put new carb kits, but since I did those changes the bike bogs a lot at the take off and when hitting high rpms in 3rd gear.. Some people say its not getting enough fuel some say its the sparkplug??? any suggestions...... Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted March 12, 2018 Report Share Posted March 12, 2018 What bore, stroke, dome cc's, & timing? If a motor was built to run on pump gas, just throwing race fuel with high octane will actually lose power. What jetting in the carbs?

Ducman Posted March 14, 2018 Report Share Posted March 14, 2018 New carb kits? Did you change some jets? Quote Link to comment Share on other sites More sharing options...
Ayesully810 Posted March 14, 2018 Report Share Posted March 14, 2018 Generally, running higher compression with race fuel calls to run a COOLER plug. You should stick with the BR9ES plug (if your motor has high enough compression to run race fuel like tricked said) Quote Link to comment Share on other sites More sharing options...
ezuniga21 Posted March 14, 2018 Author Report Share Posted March 14, 2018 So I did some tuning to the bike and it’s running on br8es with 110 fuel seems to be running fine the bog isn’t there anymore but i think I’ll go down to 100 octane to not go through spark plugs like crazy Quote Link to comment Share on other sites More sharing options...
ginger Posted March 16, 2018 Report Share Posted March 16, 2018 octane should have no effect on how fast you go through plugs unless you are running way to hot. are you fouling plugs? (making them black) Quote Link to comment Share on other sites More sharing options...
