As i know you to be the engine guru that you are i got a question for you...

What is the best way to know when your Midrange needle is set where it should be on a three needle carb and can i tune the Mid needle after my LSN or before it?

Thanks for your help!!!

All of the "mid range needles" as they are refered to that I have ever used are best not touched!! LOL

If needed to be reset , they are usually all exactly flush with outside body of carburetor .

Just fyi there is a reason that our offroad carbs are not made with a mid needle anymore


I have noticed on the vspecs that I have tuned for people that they like to have the mid needle adjusted in 2 hrs .

Thats what everyone local here has been telling me as far as dont fool with it much just leave it at factory spec!

Ill see what i can do with LSN and HSN to set the tune and if all else fails ill swap it for my friends 2 needle carb!!

Thanks again

Is the shim stack on a 21BF around .80mm or less? Something like two copper .25mm and one silver .30mm?

Monty, that 2084 pipe was awesome on my p5 this weekend! It had the power of a 9853 with the runtime of a 9901. I liked it with the 41005 header. I can't wait to try it on my other novas Thanks, Mike

My N21R is .8 with 3 shims. 2-Silver 1-Copper. I'm assuming Silver=.35 Copper = .1

Mine came shimmed nicely from Monty.

I loved the pipe this weekend also , used it with 41021 and it made my 5 port work very well

Next time out I will try with a 41005 and see if there is any power difference in comparison to the 9853ss , I didn't notice any power difference if there was any

All the new engines are put out with .80mm for american market running 30%

Two x .30mm aluminum and 1 x .20mm copper

Cool. Thanx guys.

quick question, why does nova use flathead screws to secure the head? why not use a hex screw?

Easy!

Those damn hex screws drives me crasy!

If you have the right flathead screwdriver, you will tighten and unscrew the head screw without any problem. Hex screws will become worn out after a shorter time.

Donīt you guys in use torx screws? They are so much better than hex.

As with anything you do mechanically , you should have the proper tools

Why they use flathead ,that is a query for novarossi

I would venture to guess it has to do with not applying too much torque and warping the engineblock

I knew you would think of something insightful to say, thanks for the answer!

All I can do is hope the things I type get taken the right way

Anybody that actually knows me knows what I say and how I say it does not mean any ill feelings , disrespect or making people feel like a dumbass.

If anybody ever thinks I would do so intentionally , you have me way wrong

Happy motorin',
