R1-Z Dyno run
« on: September 22, 2013, 07:11:29 PM »
Took the little bike for another Dyno run yesterday, I knew I was too rich as I didn't want any problems on the 100 miles run last week, I was running 260 mains , snorkel fitted , bike has mild road tune and Swarbricks.
It gave more top end without he snorkel but was a little weak, so I trimmed an inch off the snorkel and stayed with that setting, might just remove the snorkel and go up to 300 mains though , any thoughts ?

Ah a dynostar dyno that is coming from the Netherlands 8)

Same as Neal.
Looking at your curve, I would focus on ''with out the snorkels''
Try if you can find the right mains for that modification

46HP is certainly a good start
Are there no restrictions in the pipe's it self on the R1-Z?

Everything on my R1-Z is same as UK 2MA , ie carbs, loom, CDi, barrels etc, bike is fitted with old school Swarbrick pipes, going to remove the snorkel this week and try 300 mains , just hope I don't loose any mid range, although needle is dropped a slot to position 4 from top, pilots 25 up from 20's.

Sorry, I must have over read this part

Then I would say, it definitely could use more air if the engine has a mild tune with (performance) exhausts.
So snorkels removed, and rejet.

What cdi unit do you have? Looks like there quit some differences
