I cant find any answers after a search so I will ask. I recently purchased a 2005 Yamaha XVS 650A. Classic. Its at 17,000 klicks and in pristine condition both mechanically and visually. The fellow I purchased it from told me it has been rejetted and dyno tuned. (Got all service receipts so he wasn`t lying) It also has some real nice V&H pipes. (Sweet!!) It really develops a lot more torque than a standard XVS. Quite amazing really. However, today I fired it up to go for a quick blurt. It is not cold. (Brisbane) It always likes full choke for the first 5 seconds or so with just a little throttle. Today I gave it a handfull to early and it wouldn`t start. I could smell fuel so I obviously flooded it. After leaving it for 30 mins, back to normal again and it started first kick. My question is, does rejetting to larger jets and dyno tuning make it more susceptable to this issue? Is there any strategies for better starting? It is due for its 20,000 klick service soon. Will I need to have it dyno tuned again? Any advice would be gratefully received. Regards, Randall.
