Well...
My Breva 750 starts fine cold or hot...
It idles nice on a 1100-1200rpm...
When engine is cold it pick ups revs immediately...but.. .when engine is on normal working temperature there is a just slight hesitation when I twist throttle
Other than that...everything looks OK to me
The engine has 58000km
Spark plugs...ngk...new
Tank filter ...new
Air filter...new
Exhaust...stock...but cut and opened...took everything out from silencers...and then welded back...
I just like the look of a stock exhaust...but now sounds a bit deeper and louder...


Where to start...?
What to check?
Thanks

Best way now is finish the tune up. Clean & balance throttle bodies, auto reset throttle, auto adjust, then get a map if needed.
You'll need software, cables and a laptop. Look in Todds tools for sale or in fueling for what he sells, it works.
Get a workshop manual if you don't have one already. In downloads or resources here.
