If that is all he has done to that motor those carbs are gigantic!! Quote
Leigh Posted October 2, 2007 Author Report Posted October 2, 2007 yeah i know they are lol.... i had them on mine at one point and they always ran wayyy to rich.. yeah thats what he has done... it is also bored a little but i dont think that makes a difference with jetting.. Quote
Leigh Posted October 2, 2007 Author Report Posted October 2, 2007 anyone have an idea of where he should be??? Quote
Leigh Posted October 2, 2007 Author Report Posted October 2, 2007 so do you think that carbs are just too big for the setup??? or can they be jetted to run right??? he just need a ball park range because pilot jets get expensive when you need to buy 5 or 6 of them.. thanks Quote
slowpokebanshee Posted October 2, 2007 Report Posted October 2, 2007 do you have any porting? compression? timing? etc? sounds like you would be better off with stock carbs.... Quote

slowpokebanshee Posted October 2, 2007 Report Posted October 2, 2007 yes you can run those carbs, however, you will have to run it fairly lean and would not have as much benefit as running stock carbs or maybe 28-30mm carbs....I vote for trading those big carbs for some porting.... Quote
