I prefer FI myself, but i can see how the average joe will prefer carbs so they can tune them themselves.
Fuel Injected Vs. Carburetor
Me personally...Im a carb guy because of its ease of working on, tuneability, and prices. Dont get me wrong I like the performance and smoothness and even EASE OF STARTING that FI has but I just like being able to easily and cheaply tune and clean my carb. They are more work and require some patience but in the end I think they can work just as well as fuel injection without the expensive tuners and such. Whats you opinion on it?
Sorry for the placement, this probably should have been in the POWERTRAIN thread.

i prefer carb cuz like ive said about ten times on this site already, if one wire shorts out, ONE WIRE, you cannot run the machine. Carb? As long as you get the ignotion on you can bump start it. I know all machines are gunna be FI cuz of ease and throttle response and stuff but i would take an carbed machine over FI ANY DAY. Just my opinion.
i support technology

Well obviously i'd take FI. Ease of tuning and precision. The whole one wire thing is okay with me, aside from when im trying to race, becaue then i'd know I had a short.i support technology[/b]
I like carbs just for the fact that they are cheap to tune and the average person with the right tools can do it in his garage without electronic tools
most who prefer carbs .. just don't understand FI..
it really is a MUCH simpler system!

Does the size of the carb/throttle body relate when comparing FI to carb? (I couldn't find specs on size when comparing the RMZ450 carbed version to FI version).
Reasoning is this, when big bores and big carbs are put on pit bikes (like 144, or 163 in a 110) they are a huge pita to jet with the bigger carbs and something like FI would be able to have a better jetting.
Thus, wouldn't it be easier to fine tune a large bore carb on a quad if it were instead FI? I have never had experience with a bored yfz carb but if it relates to the pit bikes a larger bore would be harder to jet.
Personally, I'm already set up with a laptop...there's 4 in my family alone, mostly because of college and stuff.

Dont get me wrong I like FI but when it comes to four wheelers and such I just like the ease of carbs. Now when it comes to cars like my mustang and such I like the FI but its another story due to the computers being more forgiving due to their ability to learn and adapt to certain extents without programmers or laptops. I just enjoy the tuning and tweaking of a carb as a average performance enthusiast (wow a couple big words there :icon_biggrin: )but can see where the FI is a better choice for others.

If one wire shorts on your carbed quad it won't run either.

lol thats true, but i am a carb guy. i understand them and i can wok on them. not so much FI. FI also (generally) weighs more.
carbs for quads, FI for cars.

I'd prefer FI, since I know some things about it.

HAHAHAHAHAH so true!

its evolution, its only a matter of time before FI is common place.
for those that arent into it because they dont know enough about it....give it time.
Can anyone remember back to the late 90's when the PJ and FCR carbs came out? they were greeted with the same response as FI is now. "we dont like it because we dont know enough about it" .....

i prefer carb, ease of tunning and there is so much basic knowledge about them out there. On the other hand, FI is the new and upcomming thing...all the kinks and bugs and knowledge about the FI yfz is not out there yet...not to mention the lack of parts for the fi ones....money for money carb is the way to go....but as more is learned about the fi, it will overcome carb and carb models will become obsolete....its only a matter of time before fi rules everything. but untill then....ill stick with carb 
The average Joe?? And we don't understand FI?? I got to laugh at both of those. I didn't know we were rocket scientists on here. Well i'm the average Joe, and i do understand FI very well after going to school for Auto Tech. I think they both have their pros and cons. Carbs are cheaper to tune yes, but more of a pain in the #@s to do so. FI is more expensive, but its easier to tune. I've ridden my buddys 09 (full exhaust, Map Pac, FCI) and his is an overall smoother power band. But mine (full exhaust, FCI, Boyesen Kwick Shot) hits ALOT harder i think. Think it pulls harder through the power band. I also beat him by about 2 quad lengths in a drag. Honestly though, if to choose i would probally take the FI, for ease of maintenence.
some people dont understand fuel injection...plain and simple. Nobody said we were rocket scientists... :blah we are just a bunch of guys havin fun. i know guys who didnt go to school for auto tech that know about fi as well. I went to school for Auto tech too and have been a mechanic for years now and currently work at a Dodge dealership and i learn new things every day about fi cars. if you wanna make power, carbed yfz is the way to go. :clapThe average Joe??

I's actually like to see dyno numbers, carb vs FI. Just to see the comparison. The R's are so much more comfortable. I'd actually thought about getting an R rolling chassis, and putting my 05 motor in. Not sure how much of a pain in the ass it would be.some people dont understand fuel injection...plain and simple.
