Here's the situation -
My bike has recently gotten a 12K service, and one new exhaust valve (old one was burnt). The shop noticed some low speed hesitation and roughness and after much diagnostic work thought they had traced it to a vacuum leak. So I pick up the bike and notice that it once it is warm it runs very rough at the 2500 rpm level or so, either on acceleration or trying to go through a corner. I called them and they said to bring it back in because they thought the fix might not have cured it permanently.
So I'm wondering, what could be the source of the vacuum leak? Are there other things that could be contributing? (I have removed the emissions system and plugged the throttle bodies with stainless M5x10 bolts (the 10mm length seemed long, but I couldn't find anything shorter in stainless)).
So I'm hoping one of the monstergurus out there can shed some light on what might be going on.
Many thanks!
Michael
