First up, it's not likely to be just a wind gust thing, you'll generally feel those on your body as well as in the Spyder; but it
is worth checking and confirming
ALL of your tire pressures - making especially sure that the front pressures are within about +/- 1/2 a psi of each other. Those pressures confirmed, is there any chance you are still running an OE spec Kenda
ANYWHERE on your Spyder, but especially on the rear?? :dontknow:
If so, then even tho this 'slipping feeling' you get certainly could be due to quite a few other things, seeing as how many of the Kendas
do actually fail in ways that start out feeling very much like this before becoming waay more catastrophic, then I'd be checking any Kendas still fitted
VERY carefully, cos it sounds a whole lot like you may have a defective/damaged tire! Sure, a defective auto tire may also be the cause of this sort of thing, but the incidence of
that occuring is exponentially less than the number of these occurrences with Kendas, so if you've still got them fitted, be
VERY scrupulous & careful checking them out! I'd even suggest it worthwhile removing them from the rim then both visually & by feel checking the beads, tread, and sidewalls over for any soft/weak spots, any abnormal bulges or flexing anywhere, inc the tread or carcass; and closely checking/measuring for any tread depth variations in the channels around the circumference of the tire!! That should reveal even just a tiny bit of 'out of round' or a skewed tread layer, and those can cause exactly what you describe; but just like all of the others mentioned, both of those last two are often precursors of far more troubling issues! :shocked:
Then, since you've got them off the rims anyway, you might as well save yourself some time, worry, and $$ and fit some better rubber!
hyea: Just about
ANY well known/reputable brand of auto tire in a size that fits your Spyder will be a significant improvement over the Kendas in just about every respect; especially if you run those stronger & more robustly built/higher load rated auto tires at a (lower) pressure more suited to the much lighter load of your Spyder than to an automobile - even if running 16-18 psi, maybe even 20 psi since you're 'a big guy'... even if it does 'feel' a little strange & maybe even '
softer than what you've become used to' initially, it won't take long to get used to that and besides, the traction, ride, handling, and the tire life from almost any auto tire in that pressure range will almost always
still be a significant improvement over that of the OE spec Kendas or any of their stablemates/clones! :lecturef_smilie:
If you check and you exclude that 'defective tire' possibility (or you already have 'real' tires fitted) start checking out all the shock & suspension bushes (front, rear, & the swing arm!) and check the air bag (if fitted) too - dodgy bushes, broken shocks, or even just a leaky air bag/blown compressor could be creating the unsteady feeling for you.... IF/After you've ruled all those out, you'll need to start looking at things like the rear wheel axle bearings; worn or damaged suspension components; and maybe even your DPS - a dodgy power supply to the DPS/electric power steering can make it 'feel' like your Spyder's slipping & sliding down the road!
Over to you - some thoughts there that might help! :thumbup:
