Yes, try removing the cat you ran over last week.

Actually, the clunking could be several things. First, check to make sure that the nuts holding the wheels on are very tight. If they are pneumatic, check the tire pressure to see if it is at the proper level. If they are flat-free, these tires won't have valve stems and have a semi-solid core instead of a tube. Chairs that sit in one place over a period of time will develop a flat spot on the tires. Usually, if it hasn't been too long, they will go away with driving and or warm weather and driving, otherwise, you need to replace the offending tire or buy some earplugs.

Just to add to "oregoon" answer, if the flat free tyres have deformed and are the reason for your problem, rather than replacing at about 40 pounds each you can reform them by heating with a hot water bottle. take the wheel off the chair (but leave it on the hub) fill to about 2/3rds a hot water bottle with boiling water as you would if using for bed, put a tee towel around the wheel so as not to mess up the water bottle, put the water bottle around the area of the tyre that is deformed and let it heat for about 10 mins, when it has heated up remove water bottle, lie the wheel flat on the floor and place some thing flat on top (like a piece of board or something thick and flat that will stay flat and not deform as the weight is added) and then place some weight on that 10-20kg approximately try to place the weight evenly, let the weight reform the wheel to the correct shape. As it cools over about 20 mins it should reform to proper shape. If not then you will need to do the same but rather than weight you will need to shape it by hand.

good luck.

Jazzy goes fast in forward slow in reverse


It is supposed to. Forward you can see where you are going and normal steering applies. In reverse, you can't really see where you are going and it is only for backing up. Also reverse steering applies, so you turn left to go right, which is confusing for old folks, especially at speed. In Forward, the throttle should be responsive, slow to fast.

My whell chair moves too slow going forward


The 1120 can come either of 3 controllers. Find the speed control and adjust it to your desired speed. If you have the Pilot Controller the speed dial knob is at the rear of the controller. Be sure to fully charge the batteries after each use and check all connections for tightness.

Most likely you have a bad drive axle, each drive axle has 2 universal joints and when they get worn they make a big clunk sound. Especially turning or going from forward to reverse.

Makes aclunking sound sometimes down shifting is


Yes, a clunking sound is normal if it does it occasionally, not all the time. I'd check my clutch adjustment. If the clutch is dragging a bit, this makes the clunking happen more often.

Quick check of the clutch adjustment. Put the bike in low gear and pull in the clutch. Now hit the starter button. If the bike surges forward before it starts up, you need to adjust the clutch.

Also, make sure that you aren't running too much oil in your primary. Too much oil will make the clutch do the same thing as it would if it were dragging. Only enough oil to reach the bottom of the pressure spring in the clutch.

Loud Downshift


My 2004 Sporty shift pedal is "notchy" especially when cold (allow 20-30 sec. of idle after starting) to allow time for oil to wet the shift forks and gear assemblies before shifting into first driving off. Also when down shifting, I usually do NOT use engine/trans gear braking on the street to save wear and tear on the clutch and running gear...brake pads are a lot easier (and cheaper) to replace over the long haul
