ok, installed the 185 main and 45 idle jets and the bike is all good now, no more detonation and it runs great...I did have to screw in the idle mix screw a good amount, so I prolly would have been fine with the 43 idle jet...it also seems to idle and better and I can turn off the choke (enrichener) quicker than before the change...

 

Great news, well done!
