2 possible causes;
1 - the HT coils were improperly installed - the ground connection is imperfect or missing completely, you will have to verify your install.
2 - the ignition module is not operational; this happens because either the defect is in the module itself (the module has failed or it's not triggered by the timing sensor) or the wiring that connects it to the coils is damaged. Inspect the wiring to make sure it's intact and all the jacks are properly connected then test the module. If the module is good then the timing sensor is at fault - replace it.

2001 YZF 600 R thunder cat: Yamaha yzf 600 Thundercat when under heavy load or...

Many YZF 600's have a problem with second or third gear, under heavy accelleration they will jump in and out of gear, the fix is in the gear selectors,an internal box problem.
If it is a clutch problem, ride in top gear at 100kl\hr and give the clutch lever a flick, see if it grabs or slips for a while and then takes up.
