The purpose of this information is certainly not to scare off anyone interested in owning a Super X. To the contrary, there are literally hundreds of thousands of miles logged on these bikes and, considering that the bike was a whole new design, the numbers of problems have been surprisingly minimal. And generally, ample parts are available from several sources.

	Transmission	SAFETY: This is, unquestionably, the most important upgrade that needs to be addressed. Although there is healthy disagreement among the Super X owners as to the root cause of the accelerated gear bearing (aka bushing) wear, the consensus is unanimous that the transmission needs to be upgraded to prevent a lock up. There are no known injuries that have resulted from a transmission lockup, but the potential is real of a serious injury or fatality if the transmission issue is not addressed.  The “fix” is to remove the transmission, and have the five (5) gears re-bushed.  There are instructions available on removing the transmission and there are at least three repair shops located in California, Minnesota, and Virginia that have experience in repairing the transmissions.  Most of the documented failures have occurred between 8-12,000 miles, however, there have been failures of transmissions with less than 8,000 miles.

	Oil Cooler	The X Twin motor runs excessively hot and a oil cooler is highly recommended.
	Fuel Injector Collar	There is a factory warranty bulletin on the fuel line collar.
	Wheel Bearings	SAFETY: We do not recommend riding the bike until the wheel bearings have been checked or fixed.
	Throttle Body Bracket	The stock bracket that supports the throttle body between the cylinders is flimsy and will almost certainly break within the first few hundred miles.  If this is not tended to, it allows the throttle body to “droop,” thus permitting air to enter one of the cylinders which will create burned valves.  There are newly designed brackets available or there are optional air cleaner setups available that will alleviate this problem. We also recommend installing a breather filter and moving the breather line away from the air cleaner.
	Final Drive Belt	The final drive belt need to be much looser than factory specs. If the drive belt is not loosened, it quickly causes the front motor mounts to deteriorate and will also cause accelerated wear on the rear wheel bearings. Here's the tech article.
	Locking Steering Head	Don't use this feature. To many have failed and if they do you are screwed.
	Oil Level Check	There is a factory service bulletin on how to properly check the oil level.
	Synthetic Oil	Because of the issues of heat and bearing wear, we highly recommend synthetic oil, after your motor is broken in.
	Hydraulic Clutch Seal	There was a factory warranty bulletin on clutch slave seal leakage. We recommend replacing the assembly.
	ECM Tune	There are three generations of factory tunes in the bikes. We recommend the latest option of the Super X Tune program and ECM Tune 8352.
	Electrical Connections	It is mandatory to re-tighten the lugs on the battery.  Additionally, there have been many cases of shorts noted between the battery cable and the battery cover.  All electrical connections should be checked for tightness and all wiring harnesses should be checked for chafing.  There are several documented instances of fires caused by chafed wires.
	Brake Light	Check the brake light every few times you ride. By a heavy duty bulb and replace the OEM bulb.
	Chasing Threads	There was a factory service bulletin on chasing the threads in the rigid front forks prior to installing accessories.
	Positive Battery Cable	There was a factory service bulletin on how to properly route the positive battery cable.
	Crown Bolt Torque	There was a factory service bulletin on new torque specs for the 1 1/16" acorn nut.
	Ignition Switch	Every once in a while spray a small amount of WD-40 into the ignition switch.
	Handle Bar Adjustment	If you have a 1999, make sure the handle bars are adjusted so the turn signals don't hit the tank.
	Squeaky Belt	Adjust the belt so that it tracks in the center of the sprocket or it will squeak.
	Proper Torque Specs	All of the exterior fasteners, covers, etc, should be torqued according to the specifications in the Rider’s Manual.  In addition, the main drive pulley should be re-torqued.
	Tie Downs	Do not use tie downs on the handle bars. Use soft-ties around the rigid front forks. Otherwise you might ruin the handle bar isolators.
	Fuel Cap	Be sure that the plastic clip holding the throttle cables is located where it will not hit the fuel cap and scratch it.
