Mikuni carbs

Can anyone tell me what size of mikuni carbs will fit a 87CBRF1?

stock size on the hurricane is 33mm.

Thank you... I take it you dont run stock carbs?

ugh... no.

what is the next size up? and where could i get them, any one know?

Lectron Makes one bad racing carb. Used in lots of drag racing, A dodge neon I know of ran 4 lectron 50mm carbs, 1 per cylinder and got 450hp at the crank out of the motor. Car ran low 10's with them.
They have sizes starting at 30mm and going to 50mm in 2mm increments.

Tons of racing guys swear by them. Never used one however but they are supposed to be the bomb.
my 2 cents

i wonder what the price on those badboys are. they dont have it listed and im too lazy to call.

thanks alot on that and i was wondering if i wanted to stay with just like a K&N air filter and some other little upgreads like that what size would i want to go with like 40mm or smaller or what? and i know what u mean dude about not wanting to call...lol

hey rrasco I think from diging around on there site they r going to run about 250$ to 300$ i e-mailed them on the cost for mine i will tell u when i get the price for sure but yeah if yall what to c my bike click on that attachment and tell me what yall think? it is for themost part stock but yeah

hey, looks just like my bike, but stock.

as far as i know, there is no next size up. however, if you take the stock heads and port and polish the intakes, you could concievably go up another millimeter or 2. if the size increase is 2mm then the next usable size would be 34mm.

it is not recommended to go beyond the intake bore size.

my guess is the price is for each carb times 4.

thanks and i was just wondering if the swingarm off an F2 would work on a F1?
i think i will just get the carbs jeted then i dont really want all that much power i get in enough trouble as is.

Thanks

you can use f2 swingarm, but

1. the f3 is slightly wider to accomodate 5 inch rim whereas f2 is 4.5 inches.

2. the f3 swingarm/rim combo allows use of up to 180 tire.

3. if you want to use wider tire, go with wider rim and swingarm, this will cause less handling issues.

4. not quite a direct replacement as some geometry issues will need to be addressed.

5. this swingarm stuff is posted elsewhere under a seperate post.
