What's on your bench today?

Recommended Posts

I had one in that had been in to a number of dealers who charged the owner for not fixing the problem.

Always an interesting one but on this one, I found the generator loop behind the flywheel was loose. 

The symptoms were it was rough running and sounded like it was four-stroking (running rich) but it seemed to pull reasonably OK.

You may find the screws that hold the generator in place are mullered and it may be a JB weld fix but worth checking this as it is mostly overlooked.

These machines did have issues with main bearings - difficult to tell from your vid TBH.

How many use this tool for old school piston removals?

 

Guy in my FB group designed it. IMO better then the OEM one they had.

Okay thanks for your reply, will check this, does sound like similar symptoms, four stroking then picks up and revs okay.

 

Cheers.

It's 4 stroking, enriching the mixture for some reason. Try a reset on it and clean the filter out.

Filter all cleaned and blown through with compressor. Replaced plug as we have had these break down in the past. This is very early autotune so not sure what the reset procedure is with these. Thanks for the reply.

Looks like it was designed by NASA, who on earth thought that was a good idea? Completely over top top

I never like it when the top end comes off and the land around the cylinder base hasn't been pre cleaned, all that chip and oil falling in to the main bearings:(

Who would spend on a special tool to get little end out then start a strip down with all that crap still on the saw ?

Ever heard of a parts saw. ;)  All parts getting stripped from saw to sell.  Some went on other saws.

So who gives a fly crap what gets down in there.  But if you want to volunteer to clean my parts saws be my guest.  😄

Used for pressed pins that dont have circlip pistons.   Wrist pin is pressed into and out of rod end.
