When shifting from first gear and going into second the bike fights to go in second. It doesn't grind gears or anything it just goes into neutral. This doesn't happen all the time, but it does happen often enough. I'm going to do a full service on the bike this week, including a new front tire. I'll see if fresh primary fluid and a clutch adjustment makes any difference. Its like I have to guess if I'll get second gear or neutral. Not something you want to "guess" about! 36K miles and going strong! |

What kind of fluid in your tranny? If I let the shop service the bike they always put sport-trans in, switching to synth makes shifting much easier and missing gears doesn't happen so much. |

Littlebuggles, what synthetic are you running? I am interested in changing mine out as well since I am having the same shift into neutral issue as beach.... Skint |

Have you tried adjusting the shift pawl? No matter what the problem is, the transmission on a tuber is easy to work on. |

have you adjusted your primary chain... that makes finding neutral a chore and missing gears... |

Like I said I'm doing a full service on the machine this week and will do all the adjustments INCLUDING the pawl adjustment. I think (hope) this solves my missing second issue! |

CAREFULLY examine the shift drum for backing out pins, the C-clip for cracks, and the star-shaped detent plate for wear and sideplay while adjusting the pawl. This is a high-failure part in this motor! Generally what happens is, the pins back out, putting stress on the c-clip, it cracks and allows the detent plate to twist sideways and wear unevenly...now the shift pawl doesn't work correctly-Presto! Hard shifting! The new, improved detent plate is made of a harder material and the profile is improved. Probably worth your while to upgrade anyway as long as you're in there. And if your c-clip hasn't broken yet, it will. |

Ferris Before you get too far into this a couple of things. Check your fluid level, adjust your clutch and inspect, adjust your primary chain and adjust your shifter. Joe |

I think a 2001 M2 has the most updated detent plate... no? |

If you're going to go in far enough to adjust the shift pawl, you'll only be a minute away from from taking the entire transmission out. Might be a good idea to inspect the trenches in the shift drum for galling or unusual wear. It makes for an interesting day the first time you take one of these transmissions out... like exploring a new world without leaving your garage. |

Detent plate OEM, part number is 33653-90A and that is the most updated number. I'll be in there sometime tomorrow and will let you know what I find! |

Good on the detent plate. Just check those pins and that nasty little clip! |

Here's some photos of what to look for.... First, the differences in detent plates, old VS new Next, the shift drum pins...backing out. Last, the nasty little (cracked!) C-clip.

Done! All it needed was the shifter arm and pawl adjusted. I also put a new front tire (Pirelli, Scorpion Sync) on and did a full service. Man she is purring like an angry Lion, I love it! All she needs now is a good bath and a waxing. On a side note...... I'm going to have to order a new primary cover. The original owner who I bought the bike from "did his own maintenance". He stripped the hell out of the inspection cover, derby cover and primary chain adjustment. |

Don't buy a new cover! Helicoils will work just fine in this situation. You can get them from most auto parts stores, but NAPA for sure! The tool with drill bit and inserts is only about 30.00......way less than the cost of a primary cover. |

One additional note; the newly Heli-coiled threads, now steel, won't strip....ever again. So, your repaired primary is BETTER than new! |

I'm looking at just under $200 for a new primary cover, derby cover and inspection cover (all in black), including new hardware. |

I did my own maintenance on the M2, being careful with the torque specs, and mine stripped as well... Not a big deal, as stated, the helicoil repairs work perfectly. |
