    Dipping Revs - Running Lean

    Im sure Ive seen a post about this somewhere but cant figure out where.

    My valver is running very lean, wont go over 120mph.
    It has a scorpion backbox, green cotton filter and has been decat.

    Sometimes when i start her up the revs will dip down to 500-700 for about 10 seconds and then fly upto 1500 in a quick spurt of a second and repeat the process over again, unless I give it a quick bit of gas and its fine.
    Any ideas why this could be happening? It sounds like it aint firing right or its not burning the fuel right and it pushes it all thru in a brief second.

    I also cant understand why i can get to 110 in 4th and then change to 5th, i can sometimes squeeze 120 out of it but it just wont go go go anymore!! Any ideas?

    Cheers

    Mike
