Hi Everyone, My 2005 VTR250 had been riding great, until last night. Was riding home from work and noticed that under heavy acceleration, the bike feeled sluggish and the acceleration pulsed. Under slow but steady acceleration it didnt seem as bad, but when i went to get away from the cars at lights, it felt sluggish like it wasnt reving fully up through the gears. the sluggishness was around 5-9k rpm range, and didnt seem to occur in first, but more in second, third and forth. I noticed it again this morning when i went for another ride. I warmed the bike up with a bit of choke and set off, and it was there again. I havent done any troubleshooting on the bike, because, my knowledge of engines and bikes is fairly lacking (only had the bike 6 months) but am quite handy so hopefully if its a small fix or troubleshoot i can get it done. it had been servied approx 2500km ago (approx 32,000km on the clock) and was runnign fine after that. Nothing had been altered prior to the sluggish feeling. I am hoping someone can point me in the right direction as to what it may be, and what steps to take. Thanks for your help.
