My friend has a Honda Hawk 400 that jumps out of first gear when you get on it. It's as if you're accelerating and popping the clutch in and out. If you accelerate slowly, everything is fine. However once you get on it it jumps in and out of first gear. Someone told me that first gear might have a couple of teeth chipped. So if you accelerate smoothly you won't feel anything, but if there is alot of torque the gear will slip. of torque the gear will slip. This only happens in first, if you red-line it in second there's no problem. Has anyone ever had this problem? Duane Takahashi

I'm sure it's the engagement dogs on the transmission gear which are rounded off. You'll have to pull the engine and tear down the tranny to get to it. Get a Chilton or Clymer and check it out. You might have to replace the gear and the gear it mates to (with slots the dogs engage).

It sounds like first gear, but not necessarily the gear teeth may be at fault. There may be a finger missing that meshes the gears (I had this symptom on my old CL175 until the last of the three fingers broke off, then I didn't have that gear at all.) It could also be a bent shifter fork. If it was more that just one gear, I might suspect the shifter drum, but it could still be at fault for just first. In any case, it usually means splitting the housing. Tranny work on Hondas is surprisingly simple, once the engine is off the bike. If you've never taken the engine off, I don't recommend you learn now by yourself. If you've had engines off but just never split a case, you'll be amazed at how simple the transmission is to work on once you get to it. mikey at trsvax.
