Factory Pro designed, refined, CNC machined, heat treated DETENT STAR, Factory Pro's own heavy duty detent spring but NOT a new M90 clutch cover gasket. Makes shifting quicker and more positive - "virtually" eliminating missed shifts. The stronger detent spring rotates the shift drum quicker and the gears are more likely to engage under quick shift conditions - and "lazy" shifts work well, too.

---

Installation requires clutch basket removal. Impact wrench recommended
Does not require case splitting. STAR and arm are under the clutch on the RH side of the bike.
Estimated shop time: 1.0 to 2.0 hours
Suggest to do when replacing clutch plates.

NOTE! Be SURE to check that the shift detent arm does not bind when tightened up. If you shift into an upper gear, and the bike pops out of gear, consistently - That's an indicator of a binding shift arm. Some occasional stock bikes are so afflicted.
If consistently, no matter how you shift, the bike pops out of 3rd, 4th or 5th gear, that's an indicator of the detent mechanism binding.
If it pops out of only 2nd, and not any other gear, that's an indicator, not of a binding shift arm, but a sign of worn gear dogs on 2nd gear and the gear it mates with and the 2nd gear shift fork.

You'll find the binding detent arm problem if you follow the Golden Rule of shift mechanisms:
1. Turning the clutch shaft (so that the gear dogs can line up) (except Kawasakis)
2. Shift through all gears, up and down.
3.The shift star should snap into each gear with some purposefulness (when the gear dogs line up as you turn the clutch shaft).
4. If the arm doesn't follow the star properly or anything binds, STOP. Recheck your work and the shift mechanism's mechanicals.
5. If it doesn't shift NOW, it won't shift LATER, after you put everything else back together.
6. It won't fix itself.
