1991 Yamaha Moto4 250, Carb Needed

[SirMaxwell]

Any luck with manuals?

 

I need a carb in the owrst way and am have gone down a lot of rabbit holes (over 90 tabs and counting). Factory calls for a Mikuni BST34/1 (I think, but need to check manual). I don't care what or who makes the carb, just need a basic reliable carb. No Racing etc, just puttering. I currently only have the cable with the round slide attached.

Don't care if its round if I know what other parts to get to  make it all function.

 

Thanks for help, and listening, gonna go chase more rabbits I guess.

Thank you. I am sure it will help, but of course the 225 is different. Engine, body, electrical. Although I thin it has the same bolt/bore size on Carb, but again unknown.

 

This carb is causing some real waste of time. I can find carbs all around the 91 YFM250B, but not the 'exact'. Although I suspect one of the others will work, how is one to know?

 

Anyone with a 91 Yamaha YFM250B Moto4? Please help.

Thanks again Ajmboy

I have a 91 YFM250 however I just got it and it seems to need the carb adjusted or serviced and I don't have much experience with them.  Did you find the info you need? Where did you find the YFM250B carbs because I may be looking for one soon?

Any info is appreciated, thanks
