溫完機後改用25%油是否要係盤頂加介子？如要加，又加幾多呢？0.1或0.2？

用低度數 e.g. 5%, 16% run 機唔駛加.

run 好用25% 較機就記得加啦

你是否溫好部機??

作者: hulix 時間: 2009-7-22 07:30
yes,used 5% for break-in
Will add another 0.1mm head shim & use 25% for normal usage

Veay good la ,RB engine is easy to get fast ,enjoy your engine

for hot weather , better to add 0.2mm head shim for 25%. so total 0.5mm.
it will be much better for the engine unless you go racing

Brother Kitracer, just want to ask ask in hot weather, shall we consider adding shims to decrease the compression or changing the glow plug first?

thanks a lot

This is what I do.

add extra shim for hot weather, then lower back to normal during cooler weather, like 25.

It also depends how much you want to push your engine. For most people, I believe use 0.5mm for .12 and 0.8mm for 21 is safe in most condition unless weather gets below 10C.
(the air density would be very low at 10c so most will learn the engine too much to get the right temperture then the plug will fail!)

My recommendation is just general.

Playing with head shims is really the last thing I do. I am having enough trouble to set the right clutch, right Plug and car set up thats why I say 0.5mm head shim so that it is safe.

Dear Kitracer
The engine will run safety is right,but if 0.5mm shim add ,you must to keep watch for the engine to get 5 Minute running time when in the race.

When I add shim, I experinced more run time.
In theory, when you add more shim, you will reduce the timming and so you should save fuel.
Have you experince differently?

back to topic.

I also suggest use RB or Novarossi plug for this engine. You will experience different power when you use other brand plug.
