Fired my hyper sp up today, first time in a fortnight, took off down road and it wouldn't rev above 4k and had no go at all, felt like it was running on 1, switched it off and tired it up again and everything was fine. Any ideas? Could it be a dodgy plug as the bike has only done 390 mile
Alternatively, check the FUCKERARDER valve for FUCKETY-fuckness. And pump the tyres up. Sorted. Good job I spotted this.
EXBV - exhaust Butterfly valve, If the bike has laid up for a while they can stick. Or maybe it had gone into limp mode. Don't know if a stuck valve will do that (Chris might know) but if it had you probably would have got a CEL light on the dash.
