Well Lads ex-up question

[stevefzs1]

I have a Gen 1 Fazer 1000 42,000 miles has an Ivans tuning Kit and generally very smooth but it bogs down completely after you get to 7,000 rpm in every gear and it staggers up the rest of the rev clock i had a look at the ex-up valve at weekend one felt tight a little give each way the top wire and the bottom wire was a lot looser could that be the issue????????/
