Afternoon all,
Looking at the emulators for my F2. I have spoken with Brook Suspension and they say YYS don't list a definitive part number for the F2.
Does anyone know what size I need ?? Think its the 23.8mm ones ?
Cheers all,  |

Very interested to see how you get on here. I am looking to fit emulators on my LC but will need to source LC2 forks as the lc ones are too skinny to fit emulators. 32mm as opposed to 35 on the PV.
I measured my old springs from my F2 forks on my own PV and they are 28mm so I would imagine the emulators will not be much smaller than that if they sit between the spring and the damper rod. Might be 26.5 mm. I am guessing though.
Maybe jackjabba will pipe in as I know he has fitted them to his forks.
Let us know how you get on.
John

Im looking into this myself at the moment for LC11 forks on my LC . The only company I can find that list them are Race Tech . They do Emulators and different weights of springs .
They do have UK agents or you can order them from HVC Cycle in the USA if you fancy taking a chance on getting stung for the import duties .

Got a feeling that the old Xs 650 ones are the ones to go for as the stanchions are the same size. Trying to remember who else fitted them on here.

I got in touch with MikesXS yesterday enquiring if they had any dealers or outlets in the UK or in Europe. Unfortunately no they don’t.
When I enquired about shipping and the additional tax I almost had kittens. The emulators are $59 + tax and shipping was another $116 on top of that. Import tax and VAT on the total means it will be cheaper buying racetech ones from a UK dealer which will at least not be the cheaper Chinese copies (which I am led to believe are the ones sold at Mikes)
Just need the sizes confirmed and we are off 🙂

There is an Xs specialist in Holland can’t remember the name I used them when I built my Xs street scrambler in 2011. I will try to look who it is.

The Racetech site says the F2 uses the FEGV S3301, which is 26.5mm in diameter. YSS make an equivalent (I have a set to go in my Katana once the new linear fork springs arrive), but I can't remember the part number off the top of my head. www.racetech.com/ProductSearch/12/Yamaha/RZ350%20RZ350%20YPVS%20RD350LC/1989Make sure you have a look at the Racetech installation instructions as they advise brazing and redrilling the rebound damping holes. |

Are they bringing them by hand!? Whats wrong with USPS I wonder. Maybe someone can buy them and ship them from the USA to you. Dont be fooled that the Racetech ones whilst not copies are actually not Chinese lol... where are most things made now... |

Dont be fooled that the Racetech ones whilst not copies are actually not Chinese lol... where are most things made now... Yeah Jon I could not believe that either and was also disappointed by the couldn’t care less attitude when I asked about other options available. This thread however has thrown up a few good options such as YSS ones in the UK and at a proper sensible price. Also agree that most things now probably are made in China with varying degrees of quality from top notch to not so good. I believe however that if buying from a reputable brand or source then you have some degree of comeback if the product turns out to be less than satisfactory or not fit for purpose. We will get there in the end though. 😉 John |

. Welll that's a shame.
That said you can achieve 80 % of the Emulator performances
Noting that Valve only really effect Compression..Rebound Function is 80 to 90% of a Damper's actual purpose AND it remains governed by the Oil used
Try filling your forks with Mobil 1 ATF (yess!)
It's been tested as being a Very Good (centistoke ratings) Fork oil.
Cheapish to try at least.

Yes a real shame indeed however if I have to splash out a bit more cash buying this side of the water then that is what I will do. In my younger days, I only ever used Auto Transmission Fluid (Castrol TQF) and found it very good in just about every set of forks I had. It is only recently I have started using the various weighted fork oils as recommended in the workshop manuals and forums (ah the debate!!!) I have got loads of ATF in the garage (use it in the Norton primary) so I will give it a go when I put the forks back together. That is what I love about this forum, loads of great info, ideas and suggestions. |

When I had my vmax, Morley in the USA is the guru, he only used ATF in the forks

Heiden Tuning in Holland used to stock/sell the mikesXS emulators, but a quick look on their website now seems to suggest they don't anymore. Also, backing up what has already been said above, it's the XS650 emulators that are supposed to work with the 35mm LC2 as the forks are nearly (are?) identical. |

This isn't for YPVS, but for 4L0 350LC - I've fitted YSS PD 238 emulator valves to my LC, but haven't actually road tested them yet. The valves were turned down by 0.8mm on the o.d. to provide a bit more clearance (Clarence) to the fork inner. I also drilled additional holes in the damper rod, as recommended in the YSS instructions. I'm hopeful that the bike will be back on the road in the next week or two, so will let you know how it feels. I also fitted YSS fork springs as listed for the 350LC.

I got all my bits from Jon Slenzak who runs S1 Suspension in Brackley, Northants. His email is jons@s1suspension.co.uk. I've known Jon for nearly 30 years, so there may be a bit of mates rates involved, but the cost of PD valves, machining and fork springs was £165.00 including carriage. You'll have to fit the parts yourself. If you want Jon to do it, it will cost substantially more. Jon has been around bikes since forever, and was part of UK Suzuki motocross crew in the 80s.

If it's good I'll probably be doing the same. I'm planning on re-building my 4L0 forks over the winter because it feels like the fork springs came out of a biro. |

I've only ridden the bike to and from the MoT Test centre, but it felt suprisingly good; not mushy and spongey as I remember it but not harsh either. Really needs a longer ride over more varied surfaces to make a proper opinion, but based on initial impressions I'm very pleased.

By the time I'd discovered this site I was fairly well down the resto route, so didn't post the details up here. Plus, I'm still trying to get to grips with Flickr... Timing of getting the LC back on the road wasn't brilliant. Less than a week after getting it road legal I went on hols to our moneypit in France, so the only distance it's travelled since restoration is to and from the MoT test station... |
