just getting the girl ready from the winter storage,I always put stabil in her,so I changed all the fluids and pivot bearings,brake fluid and after 37000 miles going to change the plugs,checked the valve gap ok,got ngk as per chart,put them in hard to start and when I gave her throttle it would die,gap .6mm so I cleaned the old ones and bingo !!! any comments hate to waste 22$ cdn worth of plugs,I was hoping someone would have an idea why the new plugs did this,is it the gap

What were the old plugs? Did you go down or up on the heat range?
-
Rene my old plugs where Bosch XR7LDC I put NGK DPR7EA-9 and set the gap to .6mm, I see people use other plugs but I went for these type,I never had the bike started until the weekend after storage,but did have it running with the old ones before I changed them,and after starting with the NGK it wanted to die with throttle response,so put the old ones in and no problem,

Did you put these screw-on caps on the new NGKs? AFAIK Bosch plug do not need them, they have that "thick" uppper connector, NGKs only have that threaded bolt on top. If you leave away that screw-on cap, the bike might be unwilling to run

I put them on before I screwed them in,

Hmm then I do not see a reason, why the bike should not start ... I must admit, I also had a set of new NGK sparks with one having intermittend periods of beeing on strike. But I have heard the same beeing said about Boschs...maybe this happens since all the sparks are beeing produced in China...
You should at least check your HT-Leads and Ignition coils for proper resistance and bad/fouled connectors....
