Damn 90's what the heck have I bought

[Xowner]

Well i cracked the motor with no compression open........ this is what was inside....







Def a stroker crank but as far as the rest i have no clue what it is..... need to get the piston off and cleaned up a little

[Xowner]

Guys is this the CB piston?

[swifty]

oh yeah stroker crank kenny harmon cam piston is pry just a common +4 or +5 mm big bore kit but measure it up see if its like 54-55mm

Shame about the stroker crank, looks like it got hot on the small end and seized up. Im pretty sure its toast...... only thing saveable looks to bee the trans,head,cam and the engine cases...... sucks

These motors run pretty hot and its not uncommon for them to blue a little at the wrist pin area , see if its still in specs ? Is this a 90 or 110 motor , check the cc size on the cylinder .

its a 90cc engine, i know the 90 and 110 are diffrent wrist pin sizes. Im pretty sure this one is shot ill post some pictures tomorrow.

I need a complete points ignition for the 110. stator wires are bare at the case, coil is some junk aftermarket that dont fit. I want a complete working system........

You need to load that machine and drive North 2 hrs and visit me some Saturday. I am pretty sure it would be running when you leave.

Guys is there any way to confirm what kinda compression the one that is together is running? Also posting pics of the carb id like someone to id it. Thanks

I think its a vm20 or 22






Last picture is to get a reference of the size of main jet that was in the carb, keep in mind its loose on the carb cleaner straw

Just do a compression check , that will tell you if its a pop up piston or stock . Measure the intake side of the carb to see what size it is , most were 22-24mm . That isnt the main jet LOL also their is a rubber O ring that goes on that lip to seal it to the bowl . The main jet is mounted on the side of the bowl for easy access.

Is it a carb off a 2 stroke? Just asking because it has the 2 cycle fuel enriching system for the choke, where the 4 strokes have the butterfly type choke.

Mikuni offered this carb for many aftermaket applications and it is correct for the period as a race performance carb for a 90/110 .
