Hi all, I'm new to the forum so shouts out to all the other members!

I have a 1985 NS250R MC11 with about 20,000 kms on it. I haven't been riding it much during the pandemic, but used fuel stabilizer and a battery tender and would start it often. I had to go out of town for a few months over the winter and when I returned I kicked it over and it fired up but soon kind of bogged out and died. I haven't been able to restart and when I try to kick it over there is a ticking noise coming from what i believe to be the fuel pump (cylinder shaped bolted to the bottom of the frame on the right side).
I changed the fuel filter as I think it was original, but it didn't help.
I'll try to upload a picture but the file is too large. If anyone is interested in seeing a short video I could send you a google link.
Does anyone have experience with this clicking? Any help would be greatly appreciated.
Thanks Wayne
