Does anyone have any info on the Bullitt engines. I see that Nemo Racing has the new B-224 for sale now. I know it's a os based engine but does anyone have spec's on it? Like what carb is on it or what specific os engine it is based off of? Thanks in advance.

not 100% but I believe it’s a b2103 Type R

I was thinking the same thing b2103 R. I pulled the trigger and purchased the bullitt yesterday.....no pun intended. I'll give an update on my impressions and post some pics..only problem is this forum does not let you post pictures until u have a minimum amount of text posts? Anyway Im pairing it up with a new hipex fast lock system 2135 evo 2 pipe. Hoping this will be a wicked combo for buggie.

yes it is based off of the b2103 typeR

Bulitt 223

same price as the b2103 type r!!

What’s the difference between the bullitt b220 and b223? Both are supposed to be os b2101 any differences besides number? I have a b223 don’t have a b220 though

Not much i only know of the o ring under the head on the 223 maybe dlc crank

no oring on head on 223, they both have 21j carb I guess the b220 has the old insulator on neck on the carb out of old material the b223 is new material. I think there both 2101. Not sure if only difference is insulator and number?

Just the type r has it i thought they put it on it.. they need to aways

the 224 probably has the oring cause they os 2103 have them and it’s supposed to be 2103.

but yea trying to figure out differences on 223 and 220. I know the carb insulator material and numbers on head. Anything else anyone know ? Thanks

I believe back when the 220 was a thing that they were using the original 21j carb and the 223 was using the 21j3 carb. Not sure the differences, one of them is that insulator material but not sure if that is the only thing.

yea I think that’s really the main difference between the 2 carbs but I was trying to see if anything inside engine was different like crankshaft or crankcase or are they just both 2101. I Don’t have diagrams so not sure if anything else different
