1979 Honda PA50 acting weird

J.Frank T. /

I just got a 1979 Honda PA50 and it only goes up to 18 m.p.h. It has normal acceleration but it feels like there is a governer kicking in when I get it up to around 18 m.p.h.

I'm only 14 and I don't have a clue as to what is wrong. Also, by taking it semi-appart I realize that there is some sort of Automatic gear shift mechanism that looks like it has an infinate number of gearing choices but while riding it feels like there is no shifting. Please let me know if you have any information about this.

Thanx,

J.Frank T.

.. good detective work .. it IS an 'infinite' gearing mechanism called a 'variator' .. and they are smooth and you don't generally feel any 'shifting'.

As far as the PA50s are concerned .. I have one and have blabbed all about them on this forum .. use the 'search' button above .. I do believe you will find a couple hundred posts about PA's and mods in the last year.

Mine is a 78 PA50I that goes between 40 and 50mph depending on how I set it up.

(it went 21mph stock)

If they only go up to 21m.p.h. stock do I need to add a special kit or something to reach the spedometer potential of 35?

Well .. I already told you to go back and read some of those old posts I (and others) have made... right ?

So go read some of them .. it will take a while.

But first .. you need to figure which PA you have .. a PA50I or a PA50II.

The PA50II is easy to get to do 35.

The PA50I needs more work and parts.

It's a Pa50 1

I got it to do 22mph yesterday but I had more than the 25:1 fuel mixture ratio It was around 40:1 or 50:1

WARNING !

Do NOT play with your oil mixture as a "tuning tool" !!

(unless you want to seize your motor)

I wouldn't run that PA at any less than 3 oz oil per gallon of gas (43 to 1)

Frankly .. I will be running 32 to 1 from now on in mine (4 oz oil per gallon).

You probably should too.

PA50I's need several small items to get speeded up.

If you use the 'search' .. you will find out what they are.

Re: WARNING !

Fred,

Are you going to a 43:1 gas/oil ratio because of the colder weather or because of your new piston?

If it's because of the weather, do you suggest any changes in jetting as well?
