Me too! I changed oil again and rode it to work this morning and it feels strong when I roll it on like it never has before, so I figure the torque curve will show the power comin in a lot earlier

I have a theory that w/o a snorkel & airbox lid there's a vacuum created under the tank at higher speeds that robs your mixture of air causing a rich condition at higher RPMs...
It's been raining a lot down here lately, but it cleared up enough yesterday for a short ride, so I got a wild hair and put a top on the airbox and a snorkel in and rode a while. I observed that most all the stuttering past 6K RPM is gone. Man it pulls hard up there too!
I hope to get it to a dyno this week if the weather cooperates...

I've synced the carbs and it was a lot easier then I thought! Just used a 7mm with an articulating socket to get to the screw and was done in a flash!
I've got a date with a dyno today, so we'll know soon where it stands for jetting changes needed...

this was something that i had brought up previously when discussing dyno time.
i had wondered if the results would be skewed by this.

Yesterday didn't work out so I'll have to reschedule the stg1 dyno run...stay tuned!

Update
Still waiting to get the dyno run, but while waiting I changed out the mains form 200&195 to 195&190 and she runs like a champ now! If I roll it on she screams to redline, but if I go WOT it hesitates at around 7-8K RPM, so these mains are a little rich too.
Next I will change out the mains again and install 190&185, so by the time I get the dyno run done she will be makin excellent horsepower & torque w/o flat spots

FINISHED! This was only the slowest STG1 build in history, but she's finally finished with mains at 185 & 190. Makes good power everywhere and is very responsive to the throttle inputs
Fired my dyno guy for not showing up for the run I scheduled, so I will have to find another one. Butt dyno says this bike is MUCH quicker then before especially when you turn it on in 6th gear at 80 mph
I want to thank everyone who helped me along the way to make this build a success.

Excellent!!
I think you'll find your favorite part of the engine is in pull out of corners, rather than top end. That and pulling around grandpa in a short chute between corners. Smooth, flat, fat torque, baby! The thing will just launch when you twist the throttle.

Hey Guys,
I just finished reading this entire thread, start to finish.. How exciting! Can't wait to see your numbers..
Question though, is it possible to replace the pistons and cams without splitting the whole motor, or dropping the crank? Not even sure how they go in. After reading this, it's the first time I've even thought about doing it to mine.

Do a search as one chap did a write-up about just that a good while ago .....

Well, I was just thinking about doing it next winter, not this one. I just got the bike, and it only has 5000 miles on it, I got it with 1200 in middle of the summer. Feels like I'm just getting it broken in, so I'm thinking by next winter I will probably have around 10000 on it, or so. So, not sure if replacing all the bearings would really be necessary... Plus I am afraid of splitting cases... VERY afraid! Haha..

suspension first.
lightweight wheels next.
lightwieght battery.
lightweight exhaust system.
Only do the engine, if you really want to build an engine, then do it right. It is the most expensive and time consuming way to improve the performance of your bike. The reality is, it costs more than it comes to, but it is a fun, rewarding project.
