With some help from a local I will got him to install my AirSal 70cc kit with a torque spring ,kevlar belt, and the new 19mm Arreche Carb.This was the start of the mods which have turned out to be long to say the least. I could do all the mods myself (I am a machinest mechanic) but we have a familty memeber in ICU in the hospital and I would like to get the mods done before my insurance runs out and I just have no time for some time now. Well after he installed the kit and went to set the Hebo variator I had installed before i took the scooter to him.He stripped the threads on the crank as the Hyosung variator uses a reverse thread. Well he ordered a piece of the crank and then pressed them together.Well he broke that crank. So he never said what he did but I got the scooter back from him after 3 months,running but not really working great. AS we had the family member still in intensive care on life support my time was more directed away from the scoot and I just put it in the garqage.Well I contacted a shop which would look into the issues and fix what ever it needed. After talking to them I decided to just pull off the AirSal kit and put on a Malossi 70cc kit.Got me lets do it. So I took over the scooter to them via a 2hr ferry ride each way.Yes no other shop local would work on the Hyosung. So i dropped it off and we talked , new 70cc Malossi kit and check the crank at the same time.As I had installed a Hebo Variator and also brough over 12 sets of 3 weights for the variator plus the new Technigas R exhaust I had also installed not much was needed to get this scoot tuned. Well as we looked into the scoot that day we talked about replacing the front forks were well worn out (6100k only) So lets do a new front fork as well as brakes. Well after several months and I do mean months here is the progress for the 2005 Hyosung Prima Racing now 70cc. Hebo variator below Stock exhaust The stock intake on a Hyosung SF50 very small opening so changing to a larger 19mm or 21mm carb is still restricting the engine greatly. Here is what the front fork looked like with 6100 k on it remember. Here is the new Malossi front forks which were sent to a machine shop to have them machine the shaft to match. Here the new Malossi front fork is installed with spacors as well as we also put on new Dunlop treads. Also notice the new brakes need to stop this new ride quicker. Well I ordered a NEW Yasuni R exhaust as the Malossi cylinder kit we picked also was selected for altered timing and was not a bolt on.So that 70cc kit was sent to a machine shop for the outer coller of the cylinder to be machined down to fit into the block. So the Technigas R exhaust only weeks old was removed as well and the Yasuni R (for a Katan) was ordered with several other parts from scooter attack in Germany and sweet parts arrive here in Surrey BC close to Vancouver in 3-4 day.I have ordered from them several times and all orders are here in 4 days at the latest. Custom bracket was made as well the exhaust was cut and modified to fit as it was ordered for a Katana so it was not direct bolt on. Below is the frame during the mods Here is the stock intake and look at how small the port is very restrictive. I even tried to port and polish the intake but really the stock intake is very restrictive and the best mod is to make a new one Scooterattack doe offer a intake but is never instock here you can see how small the factory intake is. Finally here is the scoot on the lift with just the final stages of tuning from them. I will put the gears and new rear Bitubo rear shock in myself. Well after 8 months I still have no scooter and I have been promissed it over and over every week now for almost 2 months. So I have about given up on the shop plus if my scoot will be done correct, yes I have even went to the shop owner as he also owns the Mazda dealer above this shop. So I was about to walk away and meet them in legal action. At that point they spent every minute on the scooter and finally are getting it done. I may even have it next week.But really with dates being told over and over it will be ready I will believe it when I see the scooter sitting in my drive way. Once I get the scoot back I will put the gears and other parts I have in as well as update the complete parts list which went into the scooter.
