Anyone know the AMC size and thread. What is normal here. Yeah I checked manual. not usefull.

 I have a recently purchased rat that I am trying to bring  to life. Took ages to get tranny oil plug out. Some wanker had cut back a 14mm metric set screw running a metric course thread (1.5).He then rammed it in like he didn't give a  hoot. Some people. I am gunna have to tap it, flush it, and install new plug. I wanna install a Fumoto valve. Makes it easier and avoids these kind of problems. What size are these plugs normally.

Thanks. Scott J. Australia.

What. Do all u guys ride evolutions and pay someone else to do any work????? Is there anyone able and willing to give me 10secs here????Does anyone even know what a thread size is?

yep evo for me don't own a girls bike

y cant you tell what thread it is ??? why not get a unf tapered plug close to the size of the hole and re tap it to suit
if you have enough meat around the hole should be able to get one from any hydraulic hose mob Enzed/ pirtek

Standard there 3/8 NPT

hey Scotty what does AMC size and thread mean? I am trying to learn too.

hi scottsmad i ve work on a lot of early castiron Sporties & still own some , have had this before  someones  has ripped the thread out or stripped  the trans drain, iv'e even seen grounddown spark plugs jamed in there , once the threade is gone i put in a NPT or NFPT thread tapered allenhead  presure plug  don't have to remove clutch  , last for years , or are you looking for original look with stock drain plug , a lot of old castiron Sporties have been got@ by a lot of people that used them as & entry level Harley & just plamed them off  to the next guy , rather than fix them proper , if your after original plug fitment look @ a hellicoil  or have to  weld & redress , ,        bluestar you look prety on a pink bicycle 

girls bikes are more comfy for  us old fells. perhaps though you could piss off to the smartass section of the forum, MR dO-NOTHIN.. this is where people seek answers. Not your second hand jokes off Easy Rider. Brainless.

Thanks for those with helpful suggestions. Vernier says about half inch, but people have different ideas what inch's are. More research and I will get back to that fella who was also confused. RE the sporty, I rode 87 softail custum. After riding Guzzies, Ducaties and BMW's. I loved the motor. 6 months later, tired of poor brakes and acceleration, I went back to the Guzzi paddock. Grunt, easy maintenance and heaps of ground clear clearance. So we'll skip please that "workin my up". I already bin there and around. I like the bastard shovelheads. The sporty will be fun. I'll leave all the lookin cool to you guys and I'll just ride. I was doing the ton when most of you were squirtin out your bums, so, just a little respect.........Scott

Whateer I put back in will have a Fumoto valve. Used em for years. Once you got it in, no need to turn again. You just open the passageway with a spring action gismo and out goes the oil, Just have to deal with these yanks mad measuring system. ty

i don't what all the fuss is about ,  1 only stripped thread thats 39 years old  ?   too easy to fix , mate you can do what you like with ya fumoto valve , ithink i've done more with motorcycles than most  since 1st riding 1968

 

funny how newbies ask for help than then trash talk long time members and want respect
think you need to take a few steps back if you want to get far around here scottsmad

most Guzzie riders are a bit strange & up themself's, eastwestvtwin spagettistyle
