I am rather new to the forums and equally new to the vstar world. I picked up my 09 1300T last September and love putting miles on it. I have a question regarding the air box, and the drilling of such.
I am running it stock (as far as I know), except for the pipes, which are the Yamaha competition long drag pipes the previous owner put on it.
When slowing down to a stop and using the engine to slow the bike while gearing down, that I get some popping out of the pipes which everyone tells me is normal for more open pipes. It isn't too bad, but occasional.
After reading quite a few posts here and elsewhere about drilling out the air box to give the motor more air, I read a few things that peaked my interest.
1. Some said that with more air, a less restricted exhaust is needed. Since I have the long drag pipes already, is my bike a better candidate to add more air/power since I am assuming the current exhaust is already more open than the original?
2. I read on a post on another site that people described less "lurching" in the gears on take off. I have noticed that the throttle is very touchy (jerky - head snapping back) when opening it again after coasting. Is that the lurching they are talking about, and does the drilled air box help that?
3. I have been told that the popping when slowing down is a result of the air imbalance because of the drag pipes. Would the extra air help that symptom at all?
4. I've read about people just installing aftermarket air filters. Is that instead of, or in addition to drilling the box?
5. Is there any downside to drilling the air box?
I should add that I am not real keen on drilling holes unless it is going to be helpful or worth it. I don't feel the need to dicker with stuff unless there are some real reasons to do it.
Thanks for any help.
