Badley Posted December 12, 2006 Report Share Posted December 12, 2006 For those who use or used A 2 INTO 1 38mm. Does it use less gas than the stock setup.In a couple of hours of riding I go thru 5 gallons of gas which is no big deal. I might try a friends 2 into 1 and just curious if it uses less gas. I gathes 2 26's actually I have 28's so 2 28's =56 as opposed to 1 38 So I would say yes anyone have an answer.Thanks Quote Link to comment Share on other sites More sharing options...

You can't take the size of the carb and just double it.... Quote Link to comment Share on other sites More sharing options...
Bansh88 Posted December 12, 2006 Report Share Posted December 12, 2006 I have the 38mm. I seem to have about the same mileage Quote Link to comment Share on other sites More sharing options...
crazybluerider Posted December 12, 2006 Report Share Posted December 12, 2006 to compare dual carbs to a single carb you have to find the flow area. A 28mm carb has the area of 615 square mm. A 38mm carb is 1134 square mm. So it actually has a smaller amount of flow than the 2 28s do at 1230mm. Quote Link to comment Share on other sites More sharing options...
miller_time_nick Posted December 14, 2006 Report Share Posted December 14, 2006 don't want to steal you're thread but i was thinking about going that route also. just seems like it would be easier to jet and you probably won't burn your filters anymore(if you have inframes). idk how a single carb affects it performance wise though. is there any advantages as far as more power at certain RPMs over dual carbs? i'd like to know more about a single set-up too, if anyone has any experience with both. thanks in advance Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted December 14, 2006 Report Share Posted December 14, 2006 just seems like it would be easier to jet and you probably won't burn your filters anymore Just get some cascade heat wraps. No more burnt filters. I would think that dual smaller carbs would be more responsive. Quote Link to comment Share on other sites More sharing options...

Truckracer Posted December 15, 2006 Report Share Posted December 15, 2006 , i've seen old hot rods with triple deuces on them, always wondered why they didn't just run a big 4 barrell. must some benefits. Well, back in the day large 4 barrel carbs were not available. People use the deuces and stuff now for nostalgia sake, not performance. No carbs make more power than the big carbs you can buy today.

endofitall9 Posted December 19, 2006 Report Share Posted December 19, 2006 I run a graydon 2 into 1 with a 35mm pwk I went from using the stock carbs. I can say that from my experience that the dual carbs got better gas mileage for me but the 2 into 1 has way better response it's easier to tune and gives it that extra oomph that my banshee needed..............
