Question about 2007 Yamaha XVS 650 Dragstar Classic

1 Answer

I cut the baffles out of my 07, 650 vstar, I love the new sound but it sounded like I was popping popcorn when it was idleing. I pluged the two hoses up going to the smog device an front of the bike, it stopped popping and runs great. Will this hurt my bike by disconeting the smog canister?

SOURCE: pipes cleaning

From what I can find online it seems to be performance pipes so I'd say boost. (Of course leaving the stock baffles in.) Stock VTX1300R is rated at 75 HP so you're probably looking at about 80-85 HP depending on how generously you rejet. If you've gotta pass emissions and don't wanna rejet before each time I'd say about 78-80 if you go full race to heck with fuel efficiency I want power you could probably pull 85 with the stock carb.

SOURCE: Rejetting a Yamaha Vstar 650

No it will not. You probably don't NEED to rejet at all. If the manufacturer suggests it for your bike and pipe combination I would follow their advice. If they do not suggest it I would use a dyno to get the best performance from your new setup. Keep in mine your new exhaust only lowers the back pressure. You haven't changed the intake parameters at all as far as airflow. So any additional air going into the cylinders due to your new exhaust will only be because of the reduced volume in the cylinder while the intake valve is open. This is a rather small amount, so don't get all crazy and jump several jet sizes at once.

A service manual is a valuable tool with an aging bike. I suggest the dealer/mfr. or Clymer books. In the meantime, go to the library reference section...646 stacks should have what you need.

1999 Honda Accord; making a popping sound in idle (as if popping popcorn under the hood). What could this be?

there could be a slight hole in one of the air intale hoses and can only be heard at idle as drowned out by engine noise , i'd get the OBD codes read this should tell you which , if any , sensor/switch etc could be causing this issue, keep me posted if you wish
