The Honda PCX / Forza / ADV150 / SH Forums

Double springs are not necessary stronger. They have two major benefits usually. Each spring has it's specific spring rate - and resonant frequency. By using two different springs engineers can eliminate the single resonant frequency issue and make a slightly stronger spring what is progressive (th...

Then I would be the 22 year old engine modding fanatic :lol: . Yeah it truly is a problem. Guess I'll do as Oyabun said then. I'm running a modded SH150 variator, the clutch bell is drilled, it was made by my mechanic. Pretty good stuff, I'm 85kg, 1m75, and I can get to 100kph in like 11s or so, the...

You already have parts 1 and 11 on the bike now. I confess i don't know what size the V2 (new) 125 has for a throttle body. Yes, but you'll have to modify the inlet tract to match the bore and don't forget the injector! I don't know who did his cylinder head. Your guy should be able to do it? I don...

Also will I need parts number 1 and 11? Not really sure what that is.
Revving to 11k rpm is insane
About the cbr 150 throttle body.. just buy it and slap it on?
Did you do some work for him on the cylinder head to fit in the cbr250 valves? What diameters are those btw?

^ yep that is the correct page they are the same length as std. PCX. You need all the bits 7,8,9 & 10. Found the receipt, one set for one valve is 197 baht. #9 is the most expensive part at 142 baht. E10 has a higher octane than normal gasoline/petrol if you have that. Literally cannot thank yo...

Or you can do a 150 if you're too concerned with safety. Just use a sonic piston. I ordered it from here. Hispeedpiston. Saved my ass.

Well if you bought the 14100-KZY-25086 camshaft You are correct as it says: *The X250 ESP 8.6 camshaft has the highest lift possible in a PCX125 eSP head, and this camshaft can not be installed without the Yuminashi High-Lift eSP intake rocker 14430-KZR-000 & High-Lift eSP exhaust rocker 14440-...

YOU need the hi lift rocker arms for that cam!(or grind(file)your stock ones... been there done that :lol: Thank you, I will order those rocker arms then. In the mean time, would it make too much damage to the stock rocker arms or the yuminashi camshaft? By the way, did you happen to measure the ma...

It would not work properly.. The 58mm piston from honda has a 14mm pin. Learned it the hard and painful way

Hi, first post here. I have purchased some performance mods for my PCX 125 esp 2014. 1/ Yuminashi high lift camshaft ESP, not the RR version, the first version, got it from a friend who bought it but never used it. 2/ New 58mm piston and PCX150/SH150 cylinder, my piston has 13 pin, which is original...
