VStar 950 Overheating with 87 fuel
Had the VStar 950 for 3 years now and did the whole Cobra Slip On - Cobra Air Intake w/ K&N - Fi2000 FMS upgrade. Have been running her on Unleaded Octane 91 (I'm in Canada), but recently saw a pic on another yamaha forum of someone's vstar engine full of carbon residue after using Octane 91-93. So, I decided to play it safe and filled in the 87 but it definitely affected the performance:
- The bike is suddenly running REALLY HOT in the city (Light to Light) riding. Since the FMS is manually set, maybe there's an issue with running lean.
- The bike had stopped backfiring on downshifts. I guess a good thing.
- Not sure if the acceleration is any different now, and can't say that it is sluggish or not, but that overheating caught me completely off guard.
Did anyone have a similar experience or perhaps know what could be the issue?
