I just got done drilling mine, the sound is better, but not GREAT. Although I may not like it whole lot, the ability to put the knock out plugs in gives me the versatility I want. You drill under the bike on both sides, up into the exhaust, I used a uni-bit(step bit) to get to 7/8 of an inch, which holds the plugs very snug. It also seems that it will cut down on the smoke build up on the wheel and the pipes.
As someone thinking of doing this mod. Can you tell me what you don't like about the sound. As everyone that's done it thus far seems to love it, I'd be interested in you're opinion on why you're not over the moon with it.
Its about 3 times louder, and rumbles. I don't want you to think it sounds BAD, because it doesn't. It's just a little too loud for me. If you want to hear the difference give me a call, and Ill put the plugs in, and then take them out. So you ca hear the difference. 856-428-9718.
Hi all, I'm getting set to take the drill to the muffler but I was wondering how come nobody has started out drilling like a 1/4 inch hole & then try that out for awhile then if you want louder go to a 1/2 inch & so on, if some one has done this please respond & let us know why you went with a larger hole if you did.
well....i started with a half inch hole. I rode it one day...about 20-25 miles. After hearing Ken's before with one inch hole, i knew i wanted a bid deeper and throatier sound...and therefore, would need a bit bigger hole. Then i went to 7/8 hole...so i could use half inch conduit plug to fill it. It sounded QUITE A BIT BETTER...than the half inch hole. But finally, i decided maybe i could even go a bit more. So JUST TODAY...i enlarged with a vari bit from 7/8 to 1 1/8. 3/4 inch conduit plugs just do fit the 1 1/8. Hole. Now it sounds EVEN COOLER....a bit more louder...a bit more deeper/throatier. But i'll admit, i would NOT want it any louder on the road on a long ride. Around town...it is PERFECT. SOunds really cool.
But on a long trip...it might be a bit much. one inch is probably the PERFECT size for sound...for me. But then, i could not have plugged the hole with a conduit plug. So i went to the 1 1/8. i like it...just don't want it any louder.
That said, i'll probably NEVER put those conduit plugs in. it just sounds too cool. ALso, i rode it 85 miles today after drilling...and i noticed with 1 1/8 hole...it is harder to get it to 'pop' if you get on the throttle hard and then back off quickly.....which sometimes makes it 'pop' or slightly backfire after the mod...at certain RPMSs....as i noted here before. WIth 1 1/8 hole, it almost never does that (just to reiterate....this only happens if you grap a fist full of throttle...crank it hard....then slam the throttle shut....and then, only at a certain RPM range...and not every time...so it aint no big deal). 7/8 sounds pretty good. 1 or 1 1/8 better. anything more would be too much on the hiway for me with my windvest and half helmet on.
oh yea, i took it up to 125....couldn't see any difference in performance. and the wife and i swapped off back and forth on her non drilled Rune...just to compare. other than sound, i saw NO .....ZERO difference in performance. Just that hers sounds pretty lame to me now :wink:
She said mine sounded cool riding it...but it is too much sound for her. but then, she doesn't like pipe mods...period. i like having one bike modified...one not modified...to be able to 'actively' compare between them for reference.
- Why not - if you're not pleased after drilling - include HONDA in your summons - all in all - they provided to you FOR FREE the forum AT YOUR FREE DISPOSAL WHERE THE TEMPTATION/SEDUCTION OF YOU TOOK PLACE :?: :idea:
Those trembling under the threat of a lawsuit may rest easy, tomorrow I’m firing the lawyer.
Today I cut a 1” hole on the easy side and the sound improved remarkably. I was unable to do the left side because I need to put the Rune on a lift and that will be done this week. There is no doubt in my mind this will end up being the sound most of us wanted from the start.
Thanks epper1: to HogSlayer, RuneSki and the RedValk.
I guess if some like the 1/18" hole for some things and the 7/8" hole for others...they can simply get and extra set of 3/4" conduit plugs and drill a 7/8" hole in the center... The plugs cost pennies...
