My new 2008 Hyosung MS3-250

[Trancebear]

Just got this new to me scooter a couple days ago and I am really excited with getting it running. It needs the stator assy, rectifier (voltage regulator) and thermostat. The previous owner could not pay over $300 to have the local dealer diagnose it and then could not afford to fix it. I picked it up as-is for cheap. It came with the list of parts it needs with part numbers. I have the owners manual, service manual and parts manual with schematics.

I currently have a 2008 Jonway 150cc and 2007 250cc tourer scooters that I love. Both have taught me a ton about scooters. They just are not freeway friendly for my large size. I am 6'3", 350lbs. Yes, I played football...lol. The Hyosung is fuel injected, 4-valve, twin cam goodness with 25hp. 9 more than my Chino 250cc.

I must mention that I am coming from another scooter website that I learned a lot from but the drama was just too much. I am happy to see Terra Nuvo here and a few more. I hope to mesh right in and learn more and maybe share some of my experiences. This Hyosung is my biggest project to date and the scariest.

I hope to meet other people who have owned or currently owns one of these scooters. I read a thread here that was done in 2009 about a Hyosung 250 owner and it was very informative.

I am looking for 2 things straight away.

1. The only mods I wanna do to this scooter is improve air flow (nothing available as of yet), CVT tune/clutch (MRP has the parts I need) and exhaust. It is the slip-on type exhaust so I hope to find a muffler that will work once I find the header pipe size. Any ideas or experience with these mods?

2. Meeting other scooter owners who enjoy these awesome machines as much as I do. Especially Hyosung owners, past or present.

I have thourghly researched all the positive and negative points of owning one of these scooters and I am replacing the parts that are in question, like ALL hoses and the starter clutch.

here is a picture of my scooter before the tear-down.



My 2008 150cc. I have none of my new 250cc Chino scooter as of yet. The dark red 2010 Ford Superduty in the background is my other ride. Twin turbo diesel all the way!

Well, first, Welcome to the forum.

Next sorry to say that the 250 class scooters are not well represented here. Don't let that chase you off we can still talk about them and perhaps another 250 owner will come along too.

From what they look like to me as per a youtube video I found on one, it has the Linhai/Yamaha motor in it. So you would be using a stator from that type of scooter, the fuel injection is an upgrade from most other similar Chinese scooters.

As far as going down the freeway, it might be faster than your touring 250 but the handling might not be any better.

From what I have learned is the 250cc in the Hyosung is a cross between the CN250 and a Suzuki 250cc. They seem to make strange bedfellows.

[Trancebear]

The 250 in my Chino scooter is the Linhai engine.

[Rebel]

Ahh, I was looking around while you posted and didn't see the responses. Then it is a totally different motor. Must b more suzuki than cn250 because it does not look at all like a cn250.

[Trancebear]

According to scooterworks.com they have some parts that are interchangeable but i found a parts supplier that is very cheap and only carries genuine Hyosung parts. I will use them and MRP for the CVT.

[Trancebear]

I love the engine access. it lays down like a Linhai engine..huh?

[Rebel]

You should be all set then for parts. Care to share who the dealer is?

[Trancebear]

Hyosungsource.com for most parts and my local dealer for the smaller items like oil filters and thermostats, gaskets.

It is a Korean made bike so they do things a bit different..lol

I am hoping it rides nice on the freeway, it has 120/70-13 fronts and 140/60-14 on the back. Bigger than a 650 Burgman and the Silverwing. It sucks it requires radials according to Hyosung. $120 per tire.

[Trancebear]

Pics of the teardown, still waiting for Korean sourced parts.

[Rebel]

Pic one and ten definately show something burned. Are you going to check out all the wiring?

hyosung was a contractor for suzuki so it should be a suziki engine in it
infact the first hyosungs that came into the us had vins that called them suzuki it confused a few people at the dmv when the mco said hyosung and the vin came up suzuki

i have friend that deals hysung

I did check all the wiring, the short was localized at the voltage regulator.

You are right bud, this engine still takes many parts from the Suzuki.
