YSS "g series" rear suspension

Post by chainsaw »

I am about to fit some YSS G series shocks to my 150 and was wondering if anyone had some advice re: the settings I should have them on. I am 185cm tall and 100kgs and ride in a "sporting" fashion (kneedown,WOT and fist full of brakes). I am also fitting daytona front springs,heavier weight fork oil, Kitaco stainless brake lines and a KN Planning 260mm front rotor at the same time. I guess I am looking mostly towards PCXDEMON for advice as it is a similar setup to his scoot, but anyone with experience feel free to chime in.

WOT and knee down and looking for advice?

Avoid doing it on a scooter as you'll look silly. Do it on a real bile if you want to look like a proper dickhead

Let us know how it goes

Hi mate, rear shockies are somewhat tricky to get right if no experience is present..I found mine to work well with spring wound up about a 1/4 of a way up and dampening is set on 1 or 2 out of 5...1 being softest. Im about same height but bit skinnier then yourself at 85kg.That setting works well for me,however there could be more of a gain if adjusted more,i just havent played with it too much but this can be your starting point..
Front disc will fit nicely but caliper will struggle to sneak past rim on to the disc once its on SO dont tighten the disc all the way up so its loose little bit so you can slide on the caliper,afterwards tighten it all up.
I have a spare Takegawa vario and a Chameleon torque driver that will open up your 150 to the new level...It all comes with new rollers and seals for torque driver. PM me if youre interested. Shipping will be cheap as i live on the goldie..

Cheers

Thanks for the tips pcxdemon, you have probably saved me alot of stuffing around. I have a full Kitaco driveline with 12g sliders on its way to me and a malossi delta clutch to play with, but i want to get the suspension and brakes sorted first.I also noticed you updated an older post about modifying the Kitaco DLC pulley boss,how bad were the vibrations? do you think it would work ok if you shaved less metal off it?

I played around with the stock boss,i payed $50 for molybendium boss from Kitaco so i wasnt about to start ruining that one if it didnt work..In honesty i dont think it was worth while shortening the boss,the diff was negligible..Kitaco vario is ok but BUT it will not go past 110kmh speedo at its best. That and you have to use Kitaco belt every time for replacement is not worth it in my opinion as other belts will not work right with it,you would get even less top end speed..
Takegawa,Malossi,Daytona are the ones to go for,all use stock size belts and increase top speed up to 125-130kmh speedo..
Ultimately Yuminashi is the best you can get!! It will lift your top speed to 140kmh with excellent acceleration without much need to do anything else to your driveline...
You have a 150cc right? Well all you need is Yumi 31mm throttle,31mm intake manifold,Injector and vario and you would be over the moon with performance upgrade...I have an account with Yuminashi and im able to source stuff in if you wish to go with something from them. Take my word,Yumi is the best...

I have fitted on a set of YSS G-Pro shocks with the XL sizing for a 100kg guy. It feels a lot more firm compare to the stock shocks. Really good. This is what I have installed.

This comment should be 'pinned', it could save members messing around, getting frustrated, spending much, and achieving little.

Just for everyone else, the two generations of G-Euro that came after the ones Pcxdemon has in his video, do not have the adjustment knob on the back of the reservoir.
There is instead a regular allen head screw with no markings for adjustment, but some paint stroked across the top of it. I expect its adjusted to the spring rate and set in place with thread locker.

Hopefully this change also addressed the top of the reservoir collapsing below the seal. Quite a shame they removed the adjustment from the reservoir though...
To fix that you would need to back out the allen bolt and try and get the cap off, clean and refill with suitable fluid, put on a new seal and Loc-Tite the allen bolt back down without over-tightening.
