Gotta be careful about that...
Europe's "octane rating" is actually RON ratings. The RON rating of 95 overseas is the equivalent of 91 octane here in the states. The OP needs to seek out a RON rating of at least 97 for his fuel.

I know that, but some use 95 RON in their high compression VTX in Europe. It works fine.

did you buy the rotec supercharger? Is it worth the $3300?[/QUOTE]

Yes from TTS. Its not a bolt on and go as some would lead you to believe. I wont know for sure until the end of the month because I am traveling but I believe I have the kinks ironed out. You need the kit and new clutch and I would not use the injectors that come with the kit. I would recommend the MTC clutch and 565cc injectors instead odf the 750cc that come with it. If you are interested I will know whats up for sure about May 30th when I get to go for a ride.

Backstabber you need a go pro and record that 0-60, I don't know anybody with a supercharged bike unless it's a kawi h2r or something haha

Guys I know this thread is strayed away from the post title but could someone give me some info on the hydraulic clutch? I want to replace the fluiid but I don't know what it is or even where to put it. Mine is way low. All the manual tells me to do is "do not mix clutch fluids for they are not compatible"

It takes DOT 3/4 Brake fluid. The reservoir is on the handlebars on the headlight/turn signal control side.

Here's a great "how-to" you can follow...

WHo said they had the car tire?

I want to try it out. I have a 200 mc tire on my bike now and it need replacing. I want 65% side wall to fix the speedo, 2 birds 1 stone kinda deal, can I go with a 205? Or stay with the 200? I'm looking at the continental extremecontact dws

You will be somewhat limited by what is available for this tire size. For the most part (you don't say which model you have) some that put the 200 Metzler on their "C" had to grind off some of the fender strut bolts. Really 200 is about as wide as will fit under there. Some have moved to a 205 car tire (darkside), but the rim is kinda narrow for a car tire profile so it will pinch it in a bit. There is some variance so what will fit on one bike without issue, may need a bit of work with another, but as far as I know a 200 bike tire is it! (unless you get a wider swingarm)

That reminds me, you may be able to go to a 205 or maybe even a 210. Some have smashed in the drive shaft tube to gain extra clearance. That was some thing I was definitely not prepared to do. If you really want to do it properly, you will need a 240 kit (swingarm, fender and wheel)

I bought the 03 C it has a Dunlop 200/60r16 under it now. I can slip my thumb in between the swing arm and the tire. But only my pinky between the drive shaft and tire. Is that normal?

Yup. Depending on the manufacturer it can be even tighter. My '02 with a Metzler 200 on it had about 1/8" clearance. Definitely not enough room for more. All 200's are not exactly equal, so there is some tolerance between manufacturers, and I would suspect even between manufacturing runs.

Jakksin, If your clutch reservoir is very low, and the fluid has not leaked out, it probably means your clutch discs (fibers) are very worn.
