If It's not damp getting in try to get the FI smoothed at lower revs by a techno mechanic with a yoshi box?

[nick]

can you or anyone recomend a mech or shop that can sort my FI? london/kent area

Suzuki shop should have the basic knowledge but they'll need a Yoshi box or connector for the Raptor - I know where one is but he won't let me have it but will make enquiries - he may be able to tell me how to get hold of one - so we can have a RaptorChapter stock item

Hi, hope this helps, I can mail you a copy of this in word if you need it.

Moto One Raptor / Navigator TPS Setting Procedure


1. Remove airbox, etc, to allow complete access to throttle bodies.

2. Wind idle adjusting knob on LH side off at least two turns.

3. Disconnect throttle linkage at rear butterfly, taking care to remove the plastic washer and spring.

4. Wind rear cylinder throttle stop screw off to allow butterfly to shut completely.

5. Adjust TPS to give 1.080 volts between brown/black and grey/orange wires – front and centre. The ignition must be turned on to do this.

6. Mark screws with red paint once tightened.

7. Wind idle stop screw back in to give 1.125 volts between the two wires. This is the idle setting.

8. Reconnect throttle linkage.

9. Wind air bleed screws in full closed and set running balance. Connect vacuum gauges to fuel pressure regulator vacuum ports. Leave fuel pressure regulator vacuum lines open. Remove the other vacuum line coming from the rear throttle body next to the fuel pressure reg take off at the check valve on the left hand side and plug. Keep all other vacuum lines/electrical connectors to the airbox, etc connected.

10. Once running balance is set, set idle balance by winding up the idle stop for the front cylinder using the idle adjustment knob. Be sure not to wind idle adjustment knob too far and open throttles off rear cylinder stop screw. This may not result in correct balance, as close as possible is all that is required.

11. Finish idle balance with air bleeds if required, although this is not critical. Idle speed should be correct without needing air bleeds opened to raise speed.

12. Refit all bits.
