vtekthis Posted November 24, 2009 Report Share Posted November 24, 2009 looking for where to begin with the change over to E85. i have been recommended a 420 main and a 40 pilot, in hopes this will be a rich start to my quest for a well running alternative fuel bike. bike has typical mods, pipes, timing advance.... everything else is stock. motor carbs ect. currently bikes runs great with Q16 (127 octane oxegenated fuel from my race cars) where is the best place to get a few main/pilot jets of assorted sizes? anyone have any experience with E85 and OEM carbs? any input is appreciated! thanks Quote Link to comment Share on other sites More sharing options...
GrMeyer Posted November 24, 2009 Report Share Posted November 24, 2009 Is there a reason on why your running Q16? Unless its just sitn around the house. Are you running like 200psi and a shit load of timing? As for jets..you will have to drill your own. There are some post around here all about E85 and how people like it and dont like it. I figure if i cant run 100ll then i need to make the bike into a drag. And from what I have read is that you will be drillin out the carbs as well. changing to a dual feed petcock. Your almost better off trying to find some used 30-33mm alcohol carbs and do a rebuild on them. Quote Link to comment Share on other sites More sharing options...

camatv Posted November 25, 2009 Report Share Posted November 25, 2009 e85 is different and similar to alky. you will need to use an alky specific mix oil like klots supertechniplate or 927 those are some of the only oils that will mix with alcohol based fuels with that high of a mixture you will need the correct oil.. e85 also is not as rich needed as alky you should be able to get it jeted in with gas carbs and std jets. i havent tried it yet but on injected bikes because it is much easier to do an e85 wiht injection than a carb i couldnt get my alky lectrons lean enough to run it in one of my race bikes.. if you have extra race fuel lying around you probably be better off running that.. you can cut the fuel down by mixing it half and half with pump gas if you wanted..
