light grinding noise when started?

ive been hearing a slight grinding noise right after i start my ride. i have a new adkins streetported engine, not sure if its the starter(happens about 1 second after started, when it hits like 2500 rpms). goes away immediately, and runs fine..

the starter only turns when you turn the key.

Re: light grinding noise when started?

its right after first start of the day, not when the key is turned. the rpms jump to like 2500 and it belches a squealing noise. it actually did it twice yesterday when i hit the gas. maybe aalternator, bearing? i dont think its my rotors(at least i hope with that new rebuild from atkins....) almost sounds like a belt squeal but a little ruffer.. sorry for bad explanation..

I agree. Turbo timed everytime? If not get one imo.
