Dyno thread.

[gpz900]

I'm sure I remember someone saying they were going to start a thread for posting dyno graphs for NCs in various states of tune, to help other members troubleshoot and tune accordingly. Well, I searched I couldn't find one so consider it started. If there is one already, moderators, feel free to move this.

So, this is my bike, rescued from under a pile of leaves in someone's back garden, now cleaned, serviced, painted, and tuned by RB Racing in Sydney:
Full Yamamoto system
HRC air tray
160 mains



Dyno graph, nice clean 60hp




Cheers...

Good call. Can we make this a sticky?

Here is a graph from my 1990 'K' model Nc30.
All stock & unbutchered; airfilter, airbox, exhaust etc are standard unmodified items
The carbs have 115/118 RO supplied mains (I upped them from the original 110s) with standard float heights, standard & correct needles/tubes and 0.5mm washer under the needles.

The bike was too rich with sooty plugs & a big hole between 5-7000 rpm



I have rejetted & the bike now runs much better & I will dyno again after the winter service

Stickied for 60 days to see if there is any interest.

Found a copy of Rick (porndoguk's dyno) i'm sure he'll be along to explain the jetting and the bike. I think it was on 118/120's with a yamamoto rear / tyga can when this was done.

118F 120R Jets,
Standard Needles,
2 x washers on each needle,
Drilled Slides to 2.5mm Dia,
K&N Panel Filter,
2 x 25mm holes in the carb base plastic tray to allow more air in,
Bandaged Standard Headers,
Yamamota half section & 330mm Tyga Can

& a FUCKED chain!

alots changed since then and would love to take it back to kevs for another run to compare the charts

Just got mine back yesterday. Need to order some carbs bits as we didn't have the needles or the exact jets:



Pretty happy with this! Be interested to see what it is like with the new needles, front mains and new accl. pump diaphragm.

Setup is:

Stock motor
FCR32's flatslides:
108 MJ Front
105 MJ Rear
180 MAJ
ETV needles clip in position 4
Full Tyga exhaust (330mm oval can)

Next thing to work on is the engine build...
