I recently bought an 02 fatboy which didnt come with any manuals or build sheet so im needing some help. What kind of carb is this and is this the screw i need to be turning to adjust the amount of fuel getting to the motor. Ive sen some post saying its on the bottom of the carb.




any help would be appreciated!

 

Mikuni HSR

Any particular reason you want to monkey with it ?

 

 

It's a Mikuni, get a manual or Google it.
The idle adjustment is done with the black hose that has the end cap on it
hanging to the left side. They're the easiest to adjust.

 

After I purchased the bike it rode fine for about 5 rides. I was out prob 2 miles from the house and the bike just dies. So after sitting there for about 10-15min the bike started right back up, i made it home and left it running and it did the same thing, just died. I checked all connections and everything looks good. I took the battery to have it tested; tested good. Replaced the spark plugs, bought 2 crank sensors(haven't installed it yet, was going to do the oil and sensor this weekend). There are no vacuum leaks, cleaned the carb. I think its either a temp sensor or ecu. I watched some videos on testing the coils and they tested good. The bike is a 98ci with all the upgrades internally. Can you tell me what brand of ecu this is? Any help would be great. Thats the reason I thought it possibly could be a carb tuning issue but it was running fine before.




This has been a little frustrating after purchasing the bike, it is what it is but damn I want to ride. Fortunate the ZX10R is running good, so it hasn't been that bad
