I wanted to give an update. It's been a year and the bike has run absolutely fantastic. The pistons are A-OK in my book.

I just wanted to close out this thread with a big thank you for everyone's help. In the end I'm now running '78 carbs on my '80. Having an adjustable needle is nice. It's in middle position. Pilot is a 32.5 (stock is 27.5) Main is a 140 (stock is 135) and mixture screw is 2-5/8 turns and my...

I've built 2 other engines this year and I think the torque is giving me good numbers. All the other bolts on the head are always correctly torqued and never need tightened, just the acorns. I'll put some anti-seize on, and try again. Report back.

I've got a freshly rebuilt top end. I have run through a series of torques and break ins. I replaced the 4 outer washers with thicker copper washers. The inners are still steel. I checked the compression recently and was getting 120 left, 140 right, so I decided to do another torque and valve...

oook I went on a bit of a ride today in the twisties, not much over 1/4 throttle. It runs fantastic. I have the 1 step up from stock 30 pilot. The needle was one step leaner than stock (1 clip from top). I started with 2-3/4 turns out but it remained lean all afternoon. Every 10 minutes I...

Those are the same ones I've used for 8 years, how I didn't have issues before boggles my mind. So PK-82 or UP4200, I know you use the longer UP4200. Any reason why? I can't seem to find any comparison threads.

HOLY SHIT! I took the filters off and the midrange stutter is gone gone GONE! It runs like a demon now! I definitely will be spending some cash for some UNIs and I'll pop the 30 pilot in this saturday when it comes. Thanks for all the help fellas!

So I don't quite understand what's going on. Dropping the needle I expected to make a lean condition, but everything I see it seems to be richer. I've adjusted the mix screw from 2-1/4 to 2-1/2 and 2-3/4 and that made it worse, and down to 1-1/2, that was bad too. My plugs look wet to me. Me...

I ordered 30 pilots, and in the meantime lowered the needle one clip (raised the clip to next to highest position). Wow, what a difference that made. The bike is completely unrideable now. Very bad stutter on take off. The stutter made me think it was somehow richer, but that can't be right...

Great info, that's an easy enough thing, it's nice to have adjustable needles again. New pilots and move the needle down all the way. Maybe get some Uni filters too.

I'm all for shit talk! Well KOP I'm giving in to the pods/cv shortcomings. I rebuilt the 78 carbs I was given and managed to get them on. Started right up. I swear it sounds a hell of a lot stronger, but it still suffers from the midrange stutter. It's running the stock 27.5 pilot and 2 sizes...

There's a lot of shit talk in that post, isn't there. Anyway I rode with these same pods and carbs for 8 years with no problem. I bought it with them. No midrange issues. Quick take offs, high speeds, great curvy road acceleration. I'm just now having issues.

Yeh, with screw all the way in, it still putters midrange. I feel it is a bit better, but still sputters. Guess I'll get some jets, maybe try the 78 carbs.

It's running pods, but yes, they are on. Unfortunately I dont have either stock jet so another week for an order to come in. It runs great except for heavy acceleration or mid throttle. i probably could just zip around town like it is. I'm assuming the non epa mixture screw is letting in a lot...
