Page 4: Axle Bearing Adjustment
Why? With the Arrow karts that allow height adjustment of the rear axle, by raising the height of the rear axle in the chassis you are lowering the rear ride height. In effect, this changes the “centre of gravity”, (c/g), of your kart, which is lowered and moved back compared to the axle in its normal full down position in the chassis. -
Page 5: Height Adjustable Stub Axles
When you lower the stubs in the frame you raise the kart’s front ride height. This raises the karts c/g. as well as moving it further back. The effect on the kart will be to make it a little slower with its first-off reaction on initial steering wheel input but from then on in the front will have more grip into the apex. -
Page 6: Brake Adjustment
Note: The minimum clearance between each pad and the disc should be 1.5mm. Arrow karts brakes are supplied with 4 adjustment shims (2 x 0.5mm thick and 2 x 1.0mm thick) making adjustment simple. -
Page 7: Crash Bar Adjustment
Crash Bar Adjustment Crash Bar Adjustment Problem: “Understeer from the apex and out of the corner” Solution: Loosen or remove the bolt at the front mounting point of both side-pod supporting bars to the chassis. Side Pod Bars: Have these tightened for most conditions. Loosening these will reduce grip and can also assist in reducing understeer. -
Page 8: Front End Alignment
The first mark you made represents the outside front tyre of your kart, the second mark being the inside front tyre and the fixed end on the string being the fulcrum of the arc the kart is going through in a corner. - Page 9 On a track which offers a lot a fast sweeping corners with a fast corner leading onto the longest straight, running a lot of Ackerman will only help kill your top end speed. It’s like setting the kart with toe-out where the front tyres become dragging front brakes.
- Page 10 Running full caster in the wet is a must. In the dry increasing caster is okay when looking for better turn-in. It should be noted that too much caster would create a very nervous kart on entry to corners.

Page 12: Rear Track
However, avoid continually narrowing the rear track to obtain more grip as you will find that only so much grip can be obtained and you will then be upsetting the balance of the kart making it much more unstable and difficult to drive. - Page 13 We believe rear track is more an aid in balancing the kart and suggest you be prepared to experiment to search for your own best setting.

Seat Stays Seat Stays Problem: “There’s no traction/the kart is oversteering coming from the apex out of a corner” Solution: Mount seat stays on either side of the seat. In certain applications 2 sets of seat stays can be fitted. -
Page 15: Adjustable/Removable Torsion Bars
Adjustable Torsion Bars Adjustable/Removable Torsion Bars Problem: “There’s no traction/the kart is oversteering coming from the apex out of a corner” Solution: 1. Running the rear torsion bar “full stiff” (i.e. with the blade of the torsion bar set vertically to the track’s surface) will maximize rear mechanical grip as well as reducing rear chassis roll. - Page 16 “blade” set full stiff. When using the kart on a dry but slippery track, running with the torsion bar fitted and the blade set horizontally will give the kart more traction off the turn. On a track with a good visible rubber line we recommend that the torsion bar assembly be run “full-soft”...

Page 17: Tyre Pressures
Problem: “Understeer from the apex and out of the corner” Solution: Lower rear tyre pressures by 0.05bar/1 P.S.I. Note: Due to the many specifications and compounds of kart tyres on the market today, we suggest you seek information from your kart dealer or the particular tyre distributor. -

‘SL’ type tyres) or Arrow Euro (for high grip ‘SL’ or ‘Open’ type tyre) seats. Place the chosen seat on the floor and sit in it with your legs out flat and arms held out as if you were in your kart and driving it. You should fit all the way down into the seat. -
Page 19: Wet Weather
• Rear Track: Leave as per your dry setting or move hubs inwards 10mm each side. Narrowing the rear track too much will result in front understeer. • Caster Adjustment: If time permits, adjusting to maximum caster (indicator lines to front of kart) will reduce understeer. -
Page 20: Rear Wheel Hubs
Note: If your Arrow is fitted with a 40mm axle the wheelhubs incorporate a unique design with a wheel- locating insert. Fit the insert if you have your wheelhubs over the end of the axle and remove the insert if you want to slide your wheelhubs further inwards for a narrower rear track. - Page 21 The best way of adjusting the brake bias is to do it when the kart is on the kart stand. Adjust the brake balance bar into a position where, with pressure applied on the brake pedal, both front and rear wheels can just be turned by hand.

Page 22: Brake Maintenance
Fitting Tyres Fitting tyres will depend upon the class the kart is being assembled for. When inflating the tyre to seat the bead, do not over inflate. There is a very real risk of serious injury if the manufacturers advice printed on the sidewall of all tyres is not followed. -
Page 23: Front Wheel Alignment
The first stage to doing a front wheel alignment is making sure you’ve set the height of your kart’s steering wheel to where you find it will be most comfortable. On Arrow karts, the upper plastic bushing on the steering shaft is height adjustable by the two holes at the top of the chassis steering shaft support uprights. - Page 24 NEVER drive your Kart on any public highway, freeway, street or road. Doing this is illegal and extremely dangerous. If you decide to resell or pass on your Drew Price Engineering Pty Ltd Kart it is your responsibility to pass on all the Safety maintenance information to the next owner/operator. In the event of an accident, failure to pass on this information may mean you are held legally responsible.
