Triked my 1800 last winter found and I had a fair amount of vibration on my first few rides. Took the trike back to the installer, he took the rear tires to a local tire store and had them spin balanced which found one of them significantly out of balance. They glued a lot of weights on the inside of the rim. While it's better I'm still feeling vibration at highway speeds. Vibration is felt in my hands and feet and the view of vehicles behind me is fuzzy. I'm running 22psi in both rear tires. Today I increased the rear suspension setting up to 45 which helped a slightly.
Question: coming off two wheels where the 1800 was smooth at all highway speeds and now on three wheels, is the vib. normal given the size of the rear tires?
Running through a few possible avenues to pursue if the vib. is not normal:
* take the tires to a local tire store and have the balance check as well as tire run out. The significant amount of weight that was applied to the inner rim concerns me.
* try to determine if I have a bad rim
* replace the tires with a good brand name.
* look into a drive shaft issue
I know it's hard to quantify the level of vibration in an email but any thoughts or suggests would be appreciated.
