From what I understand you can't simply just swap out the throttle body for a carb if that's what you are thinking......that would be just too easy.

i heard that the rear shock rezzy get in the way of the carb and that when u switch to carb you dont have a rev limiter.
im not sure about this i just read it in other thread

you can swap to a 450r carb but its a very tricky task. if you want to do the swap the best thing id to just call Mike at ATP and let him do it. you send him you wire harness and thumb throttle housing he cuts out all the un-nesasary stuff for the fuel injection and you have the put threads in your throttle housing for the throttle cable to thread in. if you have a kick-start he can take even more out the harness. the carb and kick-start take 29 pounds off the LTR. also with the carb you DO have a rev-limiter. dik where you heard that. i have this setup on my race-bike i will put up some pics.

believe me dont keep wasting your money on stock gears. spend the extra money once and get mikes gears. A fellow a-class rider his 3rd went out so he bought 09 3rd gear and it lasted about a 4 months.

How can you still have a rev limiter with a carb?
When the motor reaches the max rpm's the fuel delivery is cut off to the injector.
You can't do that with a carb.

well its not nessasary a rev limiter but you get to a sertain point when all your doing is winding out your motor and your not gaining anything in which you shift to go faster. same concept as a rev limiter. you have to kno when you reach the point of your motor pulling or just crankin up and not doing anything

whats the point in putting in a carb on a FI system?? what are you going to get out of it besides maybe a few pounds or so? Suzuki has one of the best FI systems for the quads, why take it out?? it just seems point less to me

I am one of mikes sponsored riders."at atp" my race bike motor with the carb and kick start. it took 31.62 pounds off the bike. you have less to worry about and keep up. such as the injecters,throttle body sensor,fuel regualtor,fuel pump,and all the wires that go with it.
