I had my '06 converted back in May with a Motor Trike Adventure (IRS) kit and every since the rear view mirrors have been pretty much useless....

I grew up with a wrench in both hands so there isn't anything I haven't seen or done. No need to take it back to the installer since I'm smarter then he is....

I found missing weights off the rear wheels so had them rebalanced - no help.
I removed the rear wheels again and checked every bolt I could find - no help.
I checked the drive shaft and u-joints - didn't see anything I thought was abnormal.

Finally gave up and took the trike back to the dealer/installer. He pulled the drive shaft and rolled it on his desk top. Found the slightest warp. He also noted there was end play (not needle bearing wear) in the differential yoke portion of the rear u-joint. "HUMMMMMM" He says. "I don't think that's right"

Long story shortened. Two weeks later with new complete drive shaft installed I can once again see there is only one rider behind me instead of thinking the entire "Hells Angels Motorcycle Club"...

I'm guessing because the Adventure Kit has an off set drive that the end play was coming into play and causing more effect then if it were in a direct line configuration that I'm use to. Either way - I learned something new and hope I never get to use that knowledge on anybodies bike...
 
Hi Jerry, I had a similar problem (shaking mirrors) and found my (short end) drive shaft was bent also due to a stupid "fix" the installer did. He tried to weld together a mechanical union that the manufacturer designed in the original product. It eventually broke and I had a new shaft made for $325. I got a lot of experience from that situation which was one of three serious problems that I had with the kit.
 
MAKE SURE YOUR SPLINES ARE ENGAGING IN TO FRONT YOKE FAR ENOUGH
i went through 3 drive shafts in 17000 miles .my shaft only went in to splines3/8 inch
i couldnt convince motortrike it was short .they said their engineers said that was fine
i went to machine shop had spacer made PROBLEM SOLVED
