gotta_goatsfast Posted March 18, 2011 Report Posted March 18, 2011 Who says his motor is running fine with a 240 main? Quote
yamahaman244 Posted March 18, 2011 Author Report Posted March 18, 2011 Who says his motor is running fine with a 240 main? true but it idles fine and it aint acting like its lean thing pulls all the way to the top Quote
gotta_goatsfast Posted March 18, 2011 Report Posted March 18, 2011 You can put a 400 main jet in there and it will still idle fine with the correct pilot jet. Do a plug chop to see where he's at. Every motor behaves different, btw. Quote
yamahaman244 Posted March 18, 2011 Author Report Posted March 18, 2011 Yes I know but I rode it tonight and it pulled all the way on top end no sputters or anything idk mine runs fine just wondering if I should go down to get alittle more out of it Quote
gotta_goatsfast Posted March 18, 2011 Report Posted March 18, 2011 I assumed you had yours tuned. If this is true, going down in size will lean out your motor. If not, do a plug chop and start tuning. Also, just because his pulls real hard does not mean its boarderline lean. Unfortunatly rich symptoms are usually easier and make themselves obvious. A lean engine will rev high and be "zingy". So, I'm not ready to rule out that its not on the lean side. Quote
yamahaman244 Posted March 18, 2011 Author Report Posted March 18, 2011 I havet tuned mine the guy I bought mine from is friends with my dad he said he put it in there and never had any problems with it ran good which it does for me And he proby is lean Quote
sstaton1983 Posted March 18, 2011 Report Posted March 18, 2011 are the carbs the same size? maybe hes running 28s?? Quote
yamahaman244 Posted March 18, 2011 Author Report Posted March 18, 2011 That might be as of what I know I think there stock cause he was looking for bigger carbs Quote
