With stock (17/34) a 378 will hold a constant 80~90+mph with max speed around 120mph+ (very dependent on conditions/terrain) so 16 / 35 will give ludicrous acceleration assuming you can keep the front wheel down  ;D

I dont have a freeway within 10 miles of me, all back country winding roads, so i am leaning more towards the lower gearing - also considering the exhaust I plan to use won't be best for lower end power I want to stay higher in the RPMs

Low end torque is what you want for winding back country roads.

that may be true for something that redlines at 6500, this bike will be in the 11k range redline - I'll be spending all my time above 6 or 7 k.

That does make for a lot of hard work on your left toe as well as the motor.  Twisties are generally best with more low down torque and less revving its nuts off and gear changing up and down.  Just sayin'

I'm sure you guys are probably right on this - Im also paving my own way with some of what i am doing, while drawing on the knowledge and experience of others - which is why I ordered other sprocket combinations in case what I have going doesn't work to my liking. Weather in Norcal doesn't look to be slowing down any, I'm still getting all my parts together in boxes for assembly. My powdercoater source has gone off the deep end of divorce - so im stuck finding another coater or painting the frame and bits. I'm OK with either option really.

Depends who or what your chasing.  ;D
Guy on the $23,000 Paul Smart replica Ducati was 'quite impressed' with the 1974 'CB360' (on original tyres) his buddy on the 'cheaper ($18,000 Duc )was just pissed though  8)
I would still run 'stock 17/34 or even 17/33 except on my 'trail' version which has 'oversize' tyres and will be used 'in the dirt' (Blue Bike)

why do dirt bikes use suck large sprockets? like 47t on my XR400 and the GS250 I got has a huge sprocket as well

Dirt bikes need low end torque for getting over stuff and to climb trees.

Plus, 130mph on dirt is REALLY REALLY SCARY.
Don't ever gear a Maico 490 with 17/43 sprockets , 15/58 is 'safer' ;) (only use 3rd, 4th,5th unless it's a real gnarly section)

I have some carbon fiber panels and tube laying around, gonna make a battery tray out of it all to fit under the seat. spent some time in Fusion360 planning it all out. using a metri-pack 4 circuit box, OEM starter solenoid, and an AntiGravity 4cell. Probably wont use the carbon fiber top 'bar' to hold the battery down, maybe just some velcro (it's not going anywhere) will weld some tabs on the seat rails to hold it in place about 6mm below.

the extra two 10mm holes are for a toggle and push button switch (ign and start) I REALLY want a motogadget m-lock but can't justify the extra $150 I'm already deep into this project right now and haven't even purchased the wheels and tires or exhaust tubing yet.
