I have done many tunings in the motor so thats why i am searching everything details if i can get some more power.
The bike is mc28 and the tunings are:
wiring loom and pgmIII from mc21 with HRC deristrictor
spark plugs and caps from rs250
rear head conversion with squish setting to 1,0mm
HRC intake rectifiers
HRC NF5 reeds
HRC carb jet kit
JHA exhausts the model who fits only the mc28 swingarm
crankcase flow tuning and matching to the cylinders
cylinders porting
and finally i will work it in Avgas or VP high octane fuel.
I have the HRC kit for mc21 carbs only from luck,it was the only available that i could find if i could find and an mc28 jet kit i would buy it just from curiosity to test both the carbs.
I did some measures before some hours to both carbs 21/28 and i notice that they are bigger in the backside so i am happy that i have an hrc kit for the mc21 carbs
because and people with many NSR knowledges like you and Stephen suggest me to work my bike with mc21 carbs!
I have and a post on HRC nsr250 section Andy if you dont mind take a look at the question which i have for a code
thanks for all replies
