Hyosung Prima Racing SF50 ultimate build - Page 2

I don't see too many people messing with Morini engines. Looks like a neat project! It's a bummer to hear about the guys at the scooter shop giving you a hard run around...

If you need any help with your scoot, you're in the right place.

Let us know how the gears turn out. I'm mighty curious myself, as tuning options for these engines is are a little on the slim side.

Cheers!

Yes I can say the issues with the scooter shop was not even 1% of what was posted here.And with all the errors it is a front to rear over hall.

As of today July 27,08 I still have no gears to fit and have no idea what to look at for any as I have about tried all them for the Suzuki scoots.

With this scoot mods to the Hyosung I think I have done the most to any Hyosung with all the emails I am getting asking if I can help with Hyosung scooters from others.

Thanks for the comments

Anyone have idea for gears.
Anyone

**$aint** · 13-08-2008, 22:46

Well, I checked for you and it's different from a regular Morini engine (Italjet Formula 50), and for both the old (<98) and new (99>) Suzuki engines.

RAW · 13-08-2008, 22:54

So another words no susuki gears will fit

Thanks

Latest update

Well going into lighting on our scooters as everyone will agree it is bad to none depending on your scoot.

During most of the year i ride my scoot at 11pm so lighting is a issue for me as well is being visable as possible.Next the upgrades I have going.

First off the battery.OK sit down.I mean it. How about $145.00 CND for the battery.Now before you jump up and down yelling Wally has them for $35.00.
I have a little info for you.

After pruchasing a battery from Wally Mart for the low dollar price why not.So I had to cut open the sides of my battery box for the larger battery and get it to fit.Done next ready the battery.Add the ACID and put it on a trickle charge.Have lunch.Well walk away sit down 5 minutes later threw the vent the battery blew out almost 1/4 of the ACID of coause as i walked by all over my legs.

wereing shorts I can say it hurt just a little.

So much for cheap, I never want to do things twice so off to get a better battery to a few bike shops.
After 2 stops I was recommended this battery YTZ7S
http://www.yuasa.com.au/files/All_PD...a_Brochure.pdf
$142.00 CND plus taxes

So came home looked online for reviews and nothing but praise as the bike shop said i would find.

Now there is knock offs evry spot I looked labled same part number STAY AWAY they are not sealed just like the WALLY Mart battery.And specs plus build quality is not the same.

OK the battery drops into our factory location no issue at all near the same size if not the same size.No cutting modifing the case as i did for the the CHEAP battery.

Now I will have enough juice to pull up to a stop sit and my head light does not dimn at all.

Now the light bulb.

Headlightbulb Socket BA20D

35W super white halogen bulb with BA20D base. The glass is blueish so as to absorb the entire yellow spectrum of light, this way providing a very bright and cold white light like the one emitted by a Xenon lamp
These bulbs are far brighter than the 35-35 or 45watt bulb.Worth the money, but with my new battery I am going to put a 65watt bulb in.

If I get you right you want to run low beam all the time and be able to add on the high beam to that with a switch, I would think that it would shorten the life of the bulb since it will run real hot and also the generator might not be able to give it the current to go all the way, instead get a 35/35W halogen (used in Enduro bikes) and wire it like it should be done and you'll have more than enogh light for those dark Dutch nights....

The bulb on the left is a "regular" double-filament (that's used in the USA light) and the one on the right is a Halogen that fits the "regular" socket, although these are not E-certified and not 100% legal to run I don't think it's a major problem. These bulbs are often used in Enduro bikes since they handle vibration much better and with the small lights on those you want as much light as possible....

Now next upgrades I did
But mine are carbon not black like the photo but i did get them from scooterattack.

Simple to install just remove the factory rear turn lights you will need a philips screw driver and a 8mm wrnch.
Unplug the wiring on each side of the area reachable by removing the battery cover and just lifting up the battery.

I made perminant connections with connectors and heat shrink to the wires.

Then I added a few LED bulbs but again they are not equal and i by far have not tested them but these were available local and are bright.

http://www.ledshoponline.com/automotive_leds.htm
http://www.project-r.co.uk/bulbs_and_flashers.htm

There is a lot available but these ones are the ones i used below

http://files.thehoffmangroup.com/img...seflashers.jpg
A must for LED lights to change the flasher again just a few screws to remove the front cover and unplug the old and plug in the new one with adding a ground wire.
This one you can adjust the flash as well as modes. Nice touch

These were the bulbs they also carried and as well just replaced no the factory front 1156 with these plus the rear tail light as well all with clear.

Now I can be seen!!

RAW · 16-08-2008, 06:19

As of today I just removed the restrictors from the Yasuni R and the scoot fell flat on its face.
Opened up the carb to find a 72jet with a W7 metering rod.

After a few posts here I have ordered a Stage6 jet kit plus a few rods and other parts direct from Dellorto after several emails with Matt at Dellorto today. Prompt fast emails I must say thumbs up for the service emails i asked about.

Now wait till the parts arrive to see how things change.Then i will post some more pictures.

Thanks for the comment on the non standard build.Yes alot of pain to find parts just to say the least.But it is getting there.

Blitz_sr · 16-08-2008, 15:09

if you think youve got a problem, get a aprilia di-tech! jesus christ they hard to tune! theres only 2 big bore kits made for them, so its pretty limited on what you can do to them and i dont want to swap out my engine and put in a different engine, because its alot of hassle and my bike has very good accelaration for a pretty much stock 50!

RAW · 18-08-2008, 17:30

Yes no only Hyosung scooter I am sure to have the same issue.And not fun to go threw the tweeking issues while having someone close to you on and off then back on life support.Then dealing with a shop which were a bunch of idiots. Stress I just did not need . I dropped off the scoot and said here is my budget do it and do it right call me when it is ready and was told 4-5 weeks no problem.Then to get it back 3/4 of the way done with all the issues plus lots I have not posted.

Blitz_sr · 18-08-2008, 21:12

o, i see! can you post pics of how it is now? i also had another idea, why not get a engine like piaggio or minarelli and stick it in there, probabley will have to modify it to get it in there, but will be worth it as parts are sooooooo easy to get!
