- A few onboard laps on my newly built 1993 NC30. The bike runs 65hp and performed well all weekend. Unfortunately the lithium battery failed whilst on a good lap and also ended the weekend for myself as I never had a replacement, looks like total loss really harms the lithium batteries.
This was the bikes first outting after I had spent 14 months sourcing parts and building it in my garage from just a frame. Engine is a refreshed standard engine with some light headwork, runs HRC spec carbs as built by JTR, beet Japan exhaust and a ignitech syncrotech ignition system.
I raced one of these , mostly standard motor , I did work on the ports , custom 4 - 2 exhaust , modified airbox and Factory Pro jet kit . Power delivery was suoer smooth and peaked just before 15000 rpm , never went below 10000 on the track unless we had a wet race . Still one of my favourites .
65 brake??😳 that’s a rather tidy sum!👍🏻
Really goes well doesn’t it! 😎👍🏻👍🏻👍🏻
I like how the engine has different sound notes depending on the rpm
I just picked up an NC30 and found it is running with a similar power curve. Not much up towards the redline, better off around 12-13 max. Only tricky thing is figuring out what gear you are in as its so damn quiet!
This was nice to watch, I'm looking forward to returning to croft in a short while.
Hopefully see you there one day mate!

Excuse moi un 350 tz cafer 🤔
Mine ran to 15.5 no problem and pulled good til 14k so I think he's short-shifting depending on set up.
Man, that gearbox has tight ratios
the thing with lithiums is if the balance (cells)is out you get way less out of a lithium than expected,
ie if one cell is at 20% charge while the others are at 100% bms shuts down charging.
and cuts off the battery when that one cell hits minimum voltage to protect cells
so you only get to use 20% of what the battery should be capable of
also the voltage curve is so flat on lifep04 (if that is what you are using) that you could be riding out on what you think is a quite well charged battery and have anyrhing between 20-100 capacity
ie 12.9v = 20% state of charge 13.4 = 99% (if properly balanced)
i've had instances where i thought the battery was full that should last 3hrs on my ups to find that it dies 15min in
check cells and the balancing is way off
i recently built a custom lithium 12ah, and struggling to pin point a problem with approx 50% state of charge i was cranking like nuts for two days before the battery was flat , running deadloss i can just imagine that a lithium will outperform a lead acid , as the bike cranks the same on a full state of charge vs a just about flat battery just before the bms shuts down the battery
if i had not had a bit of experience with lithium i would not have thought the battery was flat when it finnaly stopped cranking
running down a lithium in deadloss until bms cuts off the battery does not damage the battery as much as it would with a lead acid
ie lead acid damages when it drops below 80%soc
and lithium only starts damaging if run below 0% soc thats when the bms cuts off to protect cells, ie 10v is what would be regarded as 0% soc (lifep04)
if it dies at higher voltages it highlights that balancing is an issue
as the bms shutsdown as soon as one cells hits 2.5v (not all bms s are configured to cut off at same volatges, these are my bms specs and what i found bumping my head)
givving way to much info i know blabbering easier to find a problem with too much info vs too little

Why isn’t the motor pulling cleanly to the makers mark?
You short shift every where
It's a new engine.
@@sam.nc30 makes perfect sense ✌️👍
What are the 2 tubes on the screen?

C'est un 400 😂
Lol! Old tech... smoking newer bikes.
