[net.cycle] Honda jumping out of first gear.

dpt@mhuxo.UUCP (TAKAHASHI) (07/10/85)

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?

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).

Happy wrenching,

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.
