TAPPET ADJUSTMENT - HOW THE HECK DO YOU GET A FEELER GUAGE IN???

(1/5) > >>

johncam:
I’m looking to adjust the tappets on my 750 four and my Clymer manual says remove the caps in the rocker cover and go from there. Only problem is the depth the tappets sit at don’t allow a normal feeler gauge in easily. Are there special bent end feeler gauges for this job? Obviously with the rocker cover off the job would be easier but I’m not sure it will come off in the frame?
All advice gratefully received and for those that replied on my carb balance item thanks again! Particular thanks to those that offered to lend me one – nice community!

Just bend over the last 3/4 inch of the feeler gauges, they go in then. (leave them bent and buy yourself another set of straight ones) And no, the rocker cover does not come off with the engine in the frame, that is a complete engine out job.

Damn good idea! Mine are rusted together it's that long since I used them.

on a 400/4, Rick Parkington's rebuild in classic Bike, he states the thread pitch of the adjuster is 0.05mm, so a single full turn of the adjuster moves it by half a millimetre or 20 thou. with the crank set to the tappet setting position,wind the adjuster down until it touches the valve and then reverse by one full turn.  two full turns equate  to  1mm or 40 thou.    not sure of other bikes thread pitch.  I' m new to honda's, i'm just posting what i read, ready to be corrected!
