420 chain - ok with 200cc?
By: Tinworm Date: January 1, 2023, 4:27 pm
---------------------------------------------------------
Gemini supplied me with a 420 / 60T plate wheel and carrier, and
I have recently been studying the link Stefan provided, which
explains chain pitch etc.
But now I am a bit concerned because I have been looking at 420
chain on ebay and it never specifies it for anything bigger than
a 160cc engine.
It makes me wonder if it is designed only for smaller engines
and wonder whether our 200cc's will be too much for it?

anyone know?

I use 08B chain on my CK because it will easily take the mighty
10hp, half links are available and I can get it for nothing from
work. It is very cheap to buy from transmission/bearing
suppliers. I use Transpower Drives in Wellrough as they are
local to Ruffden. I realise Transpower Drives sounds like it
should be a drag artist taxi company like in the TV program "A
League of Gentlemen", but it isn't.

A lot of the guys in the US use #35 chain which is 3/8 pitch and
has a tensile strength of 2100 lbs and don't seem to have any
problems.
420 chain is 1/2 pitch and has a tensile strength of 3970 lbs. I
wouldn't be too worried about it.

420 chain will be fine Peter and will be the easiest route to a
standard setup.

Blimey! Cheers
any idea what the H, B and D after the 420 mean, and which I
need?

Thanks very much Stefan
same question, you will know this, what do H, B and D mean, when
written after the 420. Coincidentally, I have a length of 420H
from another project

H = Heavy duty
Not sure about the other two.
D = Duplex?

Thanks Noel. Heavy was my guess too. I wonder what Duplex would
mean.
