Ok finally got my ST185RC on the road for summer and while it runs very smooth above 2500rpm it struggles with anything other than very light throttle under that RPM, if you let it gently accelerate from 1000rpm upwards it feels "reasonable" but its like something switches around 2500 and runs much nicer, if you try to give it more acceleration below 2500 it doesn't like it at all if you accelerate too much.
My first thought was maybe EGR as I believe that switches around then but then I found the JDM and RC models etc don't have EGR so that rules that out! TVIS is next to check to make sure its closing at lower rpm but not sure It would give the noticeable step at 2500rpm im feeling!
Ive been servicing it up and new oil, filters and basic check over but nothing obvious wronf, found 1 Vac hose starting to split but don't think it was actually leaking as yet, will check further in when I im looking over TVIS.
Any ideas welcome
Thanks
Ian
