You could have a little more fun with it. I'd hope we all new it was for laugh's:nod:

Decision time...
ran my plus 4 today with the 9901/21 header combo and then a 2058 pipe/header combo.
Top end seemed about even, but the low end with the 2058 was very snappy. And the 2058 just sounded down right mean coming off idle. :) :) Down side to the 2058 is approx 45 seconds to a minute of less run time. Granted this was not on a track so I have no timing data to back up my thoughts/feelings. To much low end could do more damage then good too. Guess I will be trying them out in practice this weekend. I was kind of hoping the 2058 wouldn't run as well as the 9901.

2058 runs great , much more power to get you in trouble ;)

if you like it and it suits what you think you want , then do it

if you do lap times vs feel then you might see the real difference ;)

:D

Now that is good to know......this is the first time I've seen an actual guidline for temps. I searched the Novarossi site, but I can't find it anywhere.....is it a "G-14, top-secret, super-classified" bit of info from your "inside sources"??? :D

I always get a little worried that I'm running my motor too hot, but this will give me a good reference point to gauge.

Engine Heat Range
 

Here you go Stubbs, scroll down to the sixth question.
http://www.novarossi.it/eng/support/faq/

I have always been the guy telling people if its smoking well operating 230-280 and has plenty of power then its fine. Just stuck an engine of mine in a friends car. It was running 250ish. Plenty of power and snap and was smoking like a fright train.... Safe. ;)

I've seen that before...nowhere in it does it recommend 165 deg above ambient.;)

I tune by performance first, but I like to keep an eye on temps to make sure I'm not getting too high. 165 above ambient is a good rule of thumb. My motors sometimes barely get over 200 during the winter months (we race outdoor nearly year round here)

nice q&a link redliner :nod:

Thats funny It says you dont need to use break in fuel and then goes on to say you should add oil to the fuel you use..making it.....BREAK IN FUEL...:lol:

And that my friend is the contrdictoriness i fight everyday ;)

thank god we have you to interpret my fellow Italians ;)

Not really James , i follow my own set of rules ;)

A little more "contrdictoriness", as Monty puts it... :D

I've always been told that the Novarossi's "like to run around 250-ish", and the 165 deg. above ambient would fit right into that, but according to the FAQ, that kind of high temp will cause the engines to wear out quickly.

[From the Nova FAQ page]:
My engine isn't old but it's "worn out", why? Learn more
Not enough cooling, running too lean, improper air filtration and cheap fuel cause quickly worn out of your engine.

The solutions:

Not enough cooling: If you don't have enough airflow over the head you won't be able to keep the engine cool.
Cut out your body according to the organizers rules.
Engine temperatures over 115�C (240�F) will cause the engine to wear quickly......


While looking at performance first, I've always had a self imposed "upper limit" of around 235 deg during the hotter months. That seemed like a happy medium between good performance, and engine longevity. I may have to just blend the two.....165 over ambient, with an upper limit of 235. ;)

2 stroke engines are cool.... but Monty is ever cooler.....
