Hi
I have instaled KL-Racing T2 camshaft/lach caps/camgear to my B230ft, and have some questions
In KL-Racing website camshaft specs say that cam needs to be instaled at 2.5mm itake lift of first cilynder at TDC.
But if i want to set the cam on 2.5mm lift at TDC, i need to fully advance my camgear at 10 degrees.


can someone give me advices ? maybe i need to jump 1 teeth of my belt and then set camgear at 0 ?

Isn´t it the fourth cylinder you´re supposed to measure at?

kl says;
''TDC lyft är angivet med ventilspel och ställs in på följande vis. Ställ motorn med kolven i toppläge( avgas håller på att stänga och insug håller på att öppna).Insugningsventilen skall då öppna angivet värde.
Värdet kan justeras något vid testkörning för bästa resultat. Ställbart kamdrev underlättar optimering av detta''

nothing about 4th cyl

i tryed this method, but then i want to make 2.5mm lift at tdc, my cam gear need to be adjusted at 10degres advance. can i jump a tooth on belt, and set cam gear at ~0, and that would be close so 2.5mm of lift at tdc ?

I don't get the problem, you have been given the information needed, lift at TDC.

You can not jump a teeth on the gear to get the TDC lift desired, the gear manufacturer will sue you in court and you'll end up in Guantanamo for the rest of your life.

om kamaxeln är advancad eller retardad vid det tdc lyft du fått får du fråga den du köpt kamaxeln av. det bestäms då man justerar till det lyft man fått.

köper man kam av mig kan man få flera tdc mått både lite advansad, nollad, och lite retardad som man sen kan testa fram i dynon eller på vägen.

ett kam drev justerar man bara på för att få rätt tdc mm, skalan visar inte vart kamaxeln är "nollad"

I was being a little sarcastic...

My advice is to do whatever it takes to get the desired TDC lift. If you have to move the belt one tooth then do it.

I would also move the belt so the adjustment is closest to centre when the cam is in the "right" position.
then you have space to both advance and retard it

what i wanted to say
thanks all to comments, ill take a dyno in friday/saturday
tryed to run on 4-6 degrees advance on camgear, much better low end on dyno i will try to run 4 -6 -8 degrees and will see

v3 run 4 degrees advance
v4 run 6 degrees advance

now need convert to LH2.4 ..
