Hi I just bought a novarossi plus4 motor off a buddy getting out of racing,but the motor has no plug or info in the box. I'm not really sure of the heat range these motors run best with,and a plug other than the over priced rossi plugs I have 3 different pipes one a JP-1,JP-4,and a old Ofna 053 pipe,which of these would be best with this motor? Or a suggestion of a better pipe and long or short header would be great

run the 53 and use an o'donnels 77t plug for cold weather and 97t for 70 plus weather...........thats what i use when i run out of nova plugs

9901/41021 for millage
9986/41021 for power
O'Donnell 97T plug

Just to add to this...

9853- torque

9901 will yield the smoothest powerband/best mileage generally.

OD97T plug is a great choice as well. Not worth the extra $$ for the Nova plugs; but if you do want to run them: C5TGC and C6TGC will have you covered.

Thanks for Info,who makes the 9901 and 9853 pipes? I'd like to try both
