suggested rev limit for a bit of a bitsa build?

[VJ]

hi guys, my project is almost done now and im just sorting out carbs etc but im interested in what people think is a safe RPM limit, I know the ecu will cut at a certain point (not 100% sure what ecu i have) but im interested in what people would spin this motor up to:

GSX1100g bottom end and barrels (1127)

Dot Head

Powerscreen 1100f cams

4/2/1 custom header with minor baffling

36mm carbs with ramair individual filters

 

im just playing with jetting now and getting close but I dont want to grenade this build from over rev.

 

 

Cheers

Depends on how well it is breathing but mostly the power peak will be 10 - 10,500. It's a strong bottom end so will turn more - but it's generally pointless. A dyno run will give you the info.

I agree with 1460, the 1100f cams will make your engine peak at relatively low rpm, e.g. 9,000 rpm, and any 1100 CDI would achieve that. Stay away from the 750 CDIs, since their rev limit is higher, and a missed gear could make your engine over rev (been there, done that, splitting an 1127 GSXR 1100 crank because of a 750 CDI on an 1127).

Cheers guys, itl see a dyno when i get paid just to help sort the jetting out. I might check the cdi number next time im in the shed now though.
