Hello all...this is my first post, so please bear with me.
I had a 1998 V-Star 650 Classic, bought new, traded it in a few months back for a 2001 V-Star 1100 Classic with 74 miles...YES, 74 miles. Apparently the original owner passed away suddenly right after buying it and his brother got it and just sat. Anyway, I bought it from a Sales Manager at my local Harley dealer (he buys bikes for cash and flips them for a small profit) and he took my 650 on trade. The 1100 was checked over at the local Yamaha dealer (which is owned by the same owner as the Harley dealership) and the oil was changed, etc. All good. I've put about 700 miles on it in the past few months, no issues. Now all of a sudden yesterday, the bike wouldn't start right up without the choke on. Then when turning the choke off, it dies. But, at idle with the choke backed off a little, a crack of the throttle will bring the rpm's up fast, but then they slowly drop down...not like they used to quickly down. I forgot to mention I added a set of Hard Krome straights with baffles in. Anyway, also, if I hold the throttle open it backfires at higher idle, not at deceleration off idle, but held open at a higher rpm. Checking the plugs, they both look okay. But at idle, again with the choke "slightly" on, with my hand over the top exhaust pipe, rear cylinder, it is popping air out, but also creating a suction effect pulling my hand into the pipe. The lower exhaust pipe, front cylinder, there is no suction effect. I'm just really freaking out that it's something major with the motor, like a bent valve or something. Anyone have any suggestions to check over before I break down and bring it to the Yamaha dealer??
Thanks in advance.
