gets overheated after like 5 minutes 3 minutes warming up almost no gas) (2 minutes quite smooth driving) ... i have good cirkulation on the water , the cooler is nice (rieju drac cooler) ,str8 waterpump . (like 0,6 l coolerwater) ..

here is a bad pic how the cooler is sitting -

I have tried with some mainjets lite 135 to 160 ...


There is no air bubbles in the cooling system.

anobody knows the problem?

Hi.

The cooling circuit you have is pretty small, 0.6l is not alot for a highend bike, Also the radiator looks good but the place its sitting is not getting much cool air / enough cool air. I would either move the radiator to the front, or run 2 radiators. If I remeber right I did a test one time and used one radiator, and it got hot so fast, the second rad makes such a difference.

Are you using any form of cooling / mix for the cooling water?

Okey! that was good , hmm , how could that help? ,

 

[black-spirit]

did you mount the inner head correctly ? i don't know how many NM you have to use to assemble it
( @ evo ) but it's a small chance that it could be your problem ...

did you use something like this tool ? =

Yep , it wasn't mounted correctly:+ , but now it is, but no difference:'(

no need for 2 radiators, can just mount a bigger one, and u should set your scooter when it's warm, and if it continues flush the radiator maybe it's clogged or something
