Thank you so much jkv
Not sure I'm following about the idle - is it idling at 1000 RPMs or something else?benito brz wrote: ↑Mon Dec 20, 2021 7:48 am
Thank you so much jkv
Now I have to adjust my carburator, my principal idle is 100 (90-95 are too low) any advice ?
Also I have coolant leaks from the downside of the cylinder, also from the headgasket , everything is New but its leaking
May I put some silicon paste ?
After fixing all that, just have to fix and paint the fairings and I'm done with it.
When I talk about my idle its about my principal idle jet in the carburator, i must choose the correct idle jet to adjust the carburatorjkv357 wrote: ↑Mon Dec 20, 2021 8:27 amNot sure I'm following about the idle - is it idling at 1000 RPMs or something else?benito brz wrote: ↑Mon Dec 20, 2021 7:48 am

Did you torque the cylinder? It's possible the mating surfaces are not perfectly flat. I've had engines (heads) that needed the surfaces to be lapped with lapping compound on a very flat surface (Quartz or Granite) in order to get a flat surface that will seal properly.
No matter what, it's going to need to come apart again to cure. Maybe someone has a good fix, but I would start with lapping the surfaces.
What does it do that makes you think the current jet isn't correct?benito brz wrote: ↑Mon Dec 20, 2021 10:33 am

Yes I torqued the cylinder and checked several times but maybe it need to be lapped like you said, the cylinder is new from 2018, but the rest upside and downside is original from the Factory, so it is "old"
