No...that NOT way too cold. Thats pretty hot actually in Europe as we're using the global standard Celsius scale > 77 to 86 Fahrenheit

So 1/8 is moving to 16% fuel as well?

Already running for several years, but next year the EFRA is going back to 25.

I figured he made a mistake lol he wrote degrees I was like 25 degrees!!! lol ice racing !!

Last year in Europeans and Worlds were they at 16%?

Yep. Last EFRA AGM there was a wish from Novarossi to go back to 25% so next year all EFRA races will be done with 25%

If countries and the ENS will follow we will see....

We are running 25% in the USA. If I purchase this engine now, would the Flash head button for 25% be the best change to accommodate the fuel?

There is a posibillity you get a 25% button with it as well. The new engine has not the same bore as the Flash so that will not work, you probably can fit a button of a Keep-on and other xtra long stroke models

Must be pretty crappy without the 'special' and always 'patented' low cg cooling fins, offset carb, stepped rear bearing etc....

can someone please advise why there are 2 different colors of heatsink for the Flash.21 PT, i saw the purple in novarossi website with black body and the other one i saw from ebay, which is black heatsink with normal grey body

The black one is a 2018 re-release but I expect due the price it is just another 35+ with a different head as many models had hit the market the last 2 years.

thanks, price wise, it is good deal.
i had a ielasi tuned PTA with a scratched piston at the exhaust side running out of fuel during run in, this might be a good replacement parts.
but considering the NR parts cost, OS still the cheapest.

running at my old lcwc cordoba, after sitting over years,, done internal cleaning, rebuild it, no missing parts (shim etc), but runs weird..

its idle quiet good while sitting on starterbox, and screaming top end, but after i gave wide open throttle on straight, the idle still hanging high for about 15 sec,, and its not idle good every coming out from corners (still revving high), tried richen LSN with the same results,, reset everything default, still had no results.
Should i adjust the Mid range needle? any advice will appreciate.

I don't know if its just the us motors but no nova .21 comes set for 16% they are all 25% with a button for 30% and al instruction booklets say 25/30%. when I say all motors I mean on road flash, mito keep-on I can take pics of the booklet if u like ..
