Frequently Asked Questions
 | Q. What is the torque setting for the rear wheel retaining nut? |
 | A. 146Nm |
 | Q. What is good for cleaning up the black ('99-'00) wheel rims? |
 | A. WD40. |
 | Q. How do I avoid getting WD40 on my discs when cleaning my
wheels? |
 | A. Spray it on the cloth, not the wheel. |
 | Q. What is a good way of carrying a disc lock? |
 | A. Cut out a rectangle of rubbery packaging foam to the size of the
underseat tray, then cut out a disc lock shape hole in it, it stops the lock
banging around. (You have already fitted a length of bungee cord with a loop
at each end to go between the lock and the twist grip haven't you - or use
the type that has an alarm built in) |
 | Q. How do I get both headlights to work? |
 | A. Two relays are required, the official ones (T2500077) are about £6
each though they are probably standard units. They go under the right side
panel on a Sprint RS (not sure about ST) |
 | Q. My metric socket set won't fit the brake hose banjo bolts, why
not? |
 | A. They are 9/16" AF bolts. Best use a 6-sided socket too
as they have rounded corners! |
 | Q. I have replaced the battery on my Datatool
Alarm remote but it still doesn't work, why not? |
 | A. Place the remote close to the alarm unit and press and hold down
both buttons for 5 seconds to re-initialise the pairing. |
 | Q. What is the effect on RPM to MPH on changing the final drive
ratios. |
 | A.

Keeping a 108-link chain will mean that other ratios alter the wheelbase
(nominal 1470 mm) and ride height as follows:
|
Height |
Wheelbase |
| 17/43 |
-1.07 |
+3.74 to 1473.74 mm |
| 18/45 |
-1.84 |
-8.51 to 1461.49 mm |
| 19/43 |
-0.06 |
-3.73 to 1466.27 mm |
A shorter wheelbase will make steeing quicker/lighter, but will mean less
straight-line stability at speed. My change to 18/45 has made a noticeable
effect in this area - IMHO for the better - but that's the way I ride!
Reduction in ride height will mean less cornering clearance, though I'm not
of the opinion that 2mm makes an awful lot of difference!
