Preciate you my main man....

Whats the size is the opening on the back of the crank on the Bf???
whats the difference with the n21r limited and n21R BF Limited??? Can you remove the head button on these motors and replace with turbo button???

If I remember correctly its 9mm but might be 8.5mm

The only real difference is that the bf uses leftover blocks from 821b , the blocks have an extra fuel diverter towards the rear portion of the horizontal transfer ports , the n21r uses the p5x case . Oh , and the r has a goofy purple head , leftovers from rb engines that are not made at the novarossi factory anymore. ;)

put a couple more tanks through the Bf with the P5 crank...starting to show some strength..have not ran the P5 i got from you yet...but will soon.

Was that bf new?

I hope the boy likes the 5 port :D

yea it was...had maybe 4 tanks through it..been trying to put a few a day when it is nice....yea we got a race the 19th-20 of this month so we cant wait.
