Thanks for the tips In fact , my engine is a 350 RDLC ( 1980-1982 ) engine ( the old brother of the RZ and bashee engines ) , so it doesn't have power valves and it's quite close to a stock banshee engine I ve modified the cases to fit a banshee / RZ 350 crank ( since the cranks are not the same ) , stroked my engine and modified the head , i use WSM log rod pistons on 65 bore and +4 mm and 115 rod I use this engine in a track bike and i run in vintage class , so i have to use the old carbs , i m only allowed to mod the "inside" engine components .... So i ve stroked it , timing is very good in fact only after stroking the engine , i ve not ported it , just flowed it , maybee , some would call this porting but i say porting when i change the timings . Now , it's 188 ex and 126 tr . It s quite compressed about 185 psi , i have to run 100LL avgas , i want a torquy engine so i m pretty close to the set up i want In fact i wanted to know : when you stroke an engine and it s the only mod you do , how goes the jetting ..... About the top end , i think i ve got DETO ( not small ping ) when going after half throttle , coming from too lean set up but i thought that going on a stroker , you should lean the main .... so my question .... ps :i ve run it on road 150 milles , nead again some more milles to get the break in finished Thanks for the replly

Hi , i ve stroked my engine , i use no spacer and have machined the head to get a positive deck i ve not yet ported it , only flowed I m using stock RDLC carbs , before stroking i was 220 on main I ve done a few heating cycles on the engine but the top end seems very strange I d like to know the jets you use before and after stroking an engine without porting it , just to have an idea ... thanks

IMO you need at least +5 ignition timing ... but what is you riding style ? Drag , trail , cross ? Compression ? .....

You'll size at the first WOT !! 0.065 - 0.075 mm !
