hello

 

I´m rebuildind my engine with pinasco crank competition 62mm stroke and malossi mhr221 and pinasco 26/26r and exhaust rz mark II

 

after measure the inlet , i have open 135º before TDC and close 75º after tdc. 210 degrees in total open.

 

my question is: sould i close the valve litle bit? or should do nothing?

 

should i weld aluminium ou use epoxy? is safe?

 

best regards

eduardo

Leave it as it is.

The timing is ok.

Please also check the flywheel cone!

The cone of my crankshaft was too long, so that the flywheel could not be fixed properly without using a custom-made washer (see picture in the link above).

 

Greetings,

Arne

Maybe a bit too much fuel consumption, but I am quite sure you will not lose power because of the intake timing.

Beside that, a MHR is not built for low revs anyway.

With your components, I‘d rather go for a Malossi Sport or Polini.
