I tried the electric impact with the clutch bell and it won't budge either. So I can try heat, liquid wrench, or use a dremel to cut the nuts off. I'll try some heat first but may not get to it for a couple of days I doubt liquid wrench would do anything for locktight. I could strangle the meathead at the factory who must have used red locktight on both nuts. I may look into fixing the air imact too but I bet it will still need heat. <sigh>

Cruiser, yes that's the one I got and will be returning.
zugzug, I am starting to think this is a reverse thread too. Has no one else seen a reverse thread on the Linhai engine? Yamaha service manual doesn't state one way or the other, I would think it would state that this is a reverse thread if it was. I'm paranoid to touch it anymore.

Dug out my old air impact wrench that I haven't seen in a dozen years and found it has a part missing, regulator I think. So Harbor Freight has a 25% off sale today and I picked up their best electric impact wrench. It wouldn't budge the nut, not one bit. I had also bought the strap wrench from Sears so I gave that a try using my breaker bar and I snapped the strap. I don't think this nut is coming off. I may fix the air impact wrench and use it but I'll probably snap the crankshaft.

Thanks for the quick replies, and here are this morning's thoughts. While I would prefer the fuel to be filtered before entering the pump, I think I will keep the larger filter I bought and install it a foot from the carb as alleyoop has done. This is something I considered doing right off anyway, and it does make it easy to check and change out in the future if needed.
Regarding the variator, I used a 1/2" drive with a 18" breaker bar on that nut and could not loosen it. The tool I made using 1/8" bar stock bent badly, needs to be 1/4". Even with the tool bending though, it held the variator stationary until the bolt hole broke. The tool uses M8 x 30mm bolts, largest I could get to fit in the holes, and I didn't shock anything by jerking the breaker bar, just a slow smooth pulling on the breaker bar. I'm surprised the bolt hole broke, and equally surprised that nut never gave. I'm actually concerned that an impact wrench might snap the crankshaft.
Well I have to go to Sears today to get an impact quality socket and maybe I'll get a chain wrench as well. Once the fan is off I'll look for possible additional damage around the bolt hole. If it looks ok I may run it until I get another fan. Cruiser, thanks for the link.
Just so you guys know, I've hanging out in this forum for a long time and am a member over at the dawg site as well. Appreciate your help and comments. I'll see if I can post some pics today.

Doing some maintenance on my Vog and have 2 concerns.
First, I'm replacing the fuel lines and filter. It had 2 filters, one between the tank and the pump, and another between the pump and carb. Both were installed backwards, no surprise. I eliminated the second one and bought a bigger, better one for between the tank and pump but it's not going to fit in the space where the old one was, which is between the tank and the plastic shield under the scoot. Just too big for that cramped space.
So the question is... does this filter need to be installed that low. Can't I run a longer fuel line from the tank up into the engine compartment, through a filter, and back down to the fuel pump? The pump is vacuum operated so shouldn't need to be right there at the bottom of the tank, as in gravity feed, right?
----------------------------------------------------------
Second - I wanted to remove the variator to clean out the abundance of grease inside the variator cover. It was so much it was leaking out of the variator cover, which had a crappy gasket that couldn't hold anything in. Need to check and clean the rollers too. I made a variator tool, but in trying to remove the variator nut, I broke one of the 2 holes in the variator. I have an impact gun but I made the tool and attempted to NOT use the impact gun for removing the variator because I wanted to reassembly the variator without the impact gun, since it's an air impact, not electric. I wanted to properly torque the nut back on.
What the heck. Can I just keep using the variator front piece as is? It won't be properly balanced with the small bolt hole part broken off (it is a very small piece). Can that be purchased separately?
I think I'll fire up the air impact and take the nut off, but don't want to use it for re-assembly.
Also that nut is standard right-hand thread, right? Counter-clockwise to remove it, right?
