Heating up chain gear on engine?

Success is mine. Fricken Finally!
I just wanted y'all to know that stubborn 32mm nut finally let go. I went out and bought a cheap-oh electric impact gun from HFT and some 1/4" hardware to bolt-up the chain as mentioned by Dave and Ed. I was supposed to be working on my outta control lawn but just couldn't get my mind on that until I tried:
It seriously took about 15 seconds of RATATATATATATATATAT on the impact gun and then finally VRRRRZZZZZZZZ! Off.
What's crazy is the impact socket is 6 point and it loaded-up on that nut so much that the left edges of the nut, all the way around, were depressed. Fricken thing spun on easy with just my fingers after I pulled the worn-out gear off:
So. Case Closed! (Gavel slam).
Now I can finally move-on and pull the engine outta the frame for some cleaning and painting! :woohoo:
Once again gentlemen. I wouldn't have succeeded without your guidance and moral support!

And yes, i already got the new gears & chain. I got stock gears for now (16/42/102 links) BUT i did wanna chat you guys up a bit about possible alternatives like going 17/40 perhaps. I know the subject has been discussed ad nauseum on the forum but i am more interested in personal experiences as opposed to technical specifics & possibilities. Like is it worth diddling with this at all?
But later I'll bring it up in the KZombie thread to keep the story in one place.

My reasons were:
- even on my 550a, i find myself searching for a 7th gear
- Average highway speed here is 70 or 75
- KZombie is a 650 so only 5 gears.
These combine to make me assume I'll wanna go non-stock with chain gears.

I agree with Ed on the stock gearing...... I've gone with a 15T front for a few hundred miles here and there just for the power down low it gives but is too much for cruising and had a 41T rear for a long time to help tame the high way rs but it only made a very small diff ..... maybe 150 rs less......... a 40T would make a little more diff but then it starts eating into those hole shots. :woohoo: A 17T front and 41T rear really killed low end and only had that on for a few days..... as you can see I went back to stock even with the hop ups ..... but you could always pick up a 17T with the 16T and see what you prefer for half way cheap.
Just wanted to add be sure you have the locking washer installed don't see it in the picture but that doesn't mean you didn't have one (could be the reason it was so tough though.... maybe he did use loctite instead).

I was using mine as a example. One thing though. If I went back to stock I'd be burning up my back tire faster than I am now. I have to buy one every 4-6 months.
