do i have to rejet my tb 250 and y do u have to rejet for

 

What are you rejeting for? If its for cold weather you should not have to rejet, But if your adding a pipe and a K&N.. By rejeting you let the engine get more fule with a larger jet, with more air you need more fule to go with it!

 

thanks man

 

You may have to adjust your air/fuel mixture screw if you plan on riding it in cold weather

 

i was thinkin about getting a pipe from rcr, would i have to rejet just for the pipe, or would i be fine just putting the pipe on without changing anything else?

 

If you put on a pipe you have to rejet otherwise it wont run right, It will run much better if you rejet more fuel more air more power!!!

 

wat do u guys think i should rejet to?? i am currently running a 160 main jet. thanks

 

You should not have to rejet But you may have to adjust your air/fuel screw to get it tuned just right for changing temps...
