- June 29, 2016, 08:12:17 AMI had excessive vibration after installing a K&N air filter. I adjusted my fuel controller and the vibration went away.
Running lean must cause vibration.. I also have Roadhouse dooleys installed and a Cobra FI2000 fuel processor.

- May 30, 2015, 05:04:35 AMAnother thing to look at is a fuel controller for the fuel injection. My bike was pretty smooth from day one, then I added a fuel controller. Let me say what a difference it made in how the bike ran once it was dialed in. The bike was noticeably smoother throughout the RPM range, was easier to start, and the plug readings were spot on. I did not really see a gain in MPG. But the bike runs smooth as silk, and has a little more getty up and go. I was a little bit hesitant about running one, I have the stock type air filter with true dual exhaust, but it made a huge difference in the way it runs.

- May 29, 2015, 21:28:19 PMI re-mounted mine using some valve cover grommets from a Ford 5.4 engine. Similar to these:
http://www.autozone.com/engine/valve-cover-grommet/mr-gasket-valve-cover-grommet-and-pcv-grommet/506105_0_0/
This is, in essence, similar to Troll's post below. I just had the Ford grommets laying around the shop.
The ford ones are the blue silicone rubber, though, should be fairly heat resistant. The trick is to use bolts and lock nuts so that you can tighten them snugly without smashing the rubber, which would take the shock absorption out of it.
Notice in Troll's picture - and the grommet in the autozone page - the rubber extends into the hole, so you get isolation between the bolt and the hole - as well as between the bolt head/bracket, and nut/bracket.

Check, I will wager it has classic pipes and a classic peg mount, making it a rubber mounted installation. Check and see if there are rubber grommets at the hanger.

- May 29, 2015, 12:13:44 PMCheck the REFERENCES tab... all of our mods, accessory sources, reference info are included under that tab.
Rubber mounting of pipes is a simple process, but it varies based upon whether or not you have pipes MADE for the Drifter (bad) or made for the Classic etc. (good).The Drifter pipes are all hard mounted which is very bad for the bike. Classic pipes are rubber mounted by replacing the right peg mount bracket with one for the classic... easy and effective.
1. If you have Drifter pipes you need to fashion a rubber mounted hanger... http://www.vulcandrifterriders.com/tbracket.html includes Trolls solution.
2. If you have Classic pipes, you just need to buy a right peg mount bracket with one intended for the Classic... same as the Drifter peg bracket except the pipe hanger part is rubber mounted.

- May 29, 2015, 08:04:50 AMWhich pipe? I posted a rubber mount solution that I've been using for years that worked very well. I have a Cobra peace pipe, and I put a set of W-650 rubber muffler mounts in it, and now, at least 25,000 miles later, it is working beautifully. I had the peace pipe off for 2 seasons, 13 & 14. I was running a totally stock exhaust. I put it back on for this year just because...Comparing the two set ups, side by side, as it were, shows me that my mod actually cuts more frame vibration out than the OEM installation.

- May 28, 2015, 21:09:56 PMSo I can not find a how to to put some rubber mounts on my exhaust bracket any help would be appreciated, Mrs. Moosewing has pretty much refused to ride the Drifter anymore and that's gonna cut into my saddletime. Already saying she doesn't want to take the bike to New Brunswick next month and I've been counting on that trip. Please someone save me.

If you are talking about the T-bracket mod those grommets are taken from the frame where the "goat bladder" from the OEM exhaust was attached. If there are no grommets in those holes now, it is still an active OEM part... P/N 92071-1270.

Rode over 100 miles today, and that vibration is awful.moosewing, fear not because GB is one heck of an awesome photo guy and will post nice clear crisp pictures of his work step by step with a write up that would make popular mechanic's green with envy.
once he starts I am sure we will have a complete synopsis on what needs to be done and were to get the parts.
