Fixed that for you.

The rotax twin in the aprilias is also one of the most unburstable engines ever made .Some had issues with clutch slave seals , but that was because they were using the wrong type off fluid in them ..They dont use clutch fluid ,they use 10w hydraulic mineral oil . Mine did 50,000 miles and never once did it let me down or have it valve clearance checked .Just changed the oil every 3000 miles .. And it was still going strong when I sold it . My buddy had a VFR over the same period and he clocked up more problems with his Honda than I did with the Italian ... Oooo did he not ever hear the end of that

The funny thing, when you think about it, is that a Honda bike with mechanical problems is as rare as a Kawasaki Ninja without stickers.

I remember his faults as I fixed them . Seized chain adjuster , dash lights fail due to burnt out circut , a coil packed up and so did his reg rec . In hindsight I think the dash light fail was a tell tale of the reg/rec failing .

Aprilia faults .. starter relay failed ,jumped the terminals to get home .. Replaced it with a yamaha one .. that was it

The story of my Ducati... oh wait, no...that was the very start

I rode my father's S1000RR once again, and once again I convinced myself I couldn't live without owning at least ONE bike that moves right from idle. I don't care much about hp, but torque is my favorite spec now

Why not synthetic?

It's the rubber they use for the seals gets eaten by yer average clutch fluid . Many KTM bikes including mine also use it. Magura brand an expensive version, I use Citroen hydro suspension fluid much cheaper and exactly the same thing.

This is why I like my cable clutches.

I dunno, I never really cared one way or the other about engine config. Some people do though. I guess starting on two smokers pretty much any 4 stroke has sufficient poke to get going and if it doesn't a little wrist and a bit of clutch slip WILL get it going.

I bought the 675 over all of the Japanese mainly for the intake wail that is skinny and fast as fuck only helps.

I have no idea what y'all are referring to as "clutch fluid". I've had a number of bikes with hydraulic clutches, and all have specified either a mineral oil or DOT4 brake fluid. What is "clutch fluid"?

Of course if your four is big enough, it doesn't matter because you have plenty of power and torque even when you aren't near the engine's peak, but then you are dealing with a quite large engine and the big bike to carry it, and I find that non-ideal. If you don't mind a big bike, such as for touring, then a big four (or even better, a six) will give you more of everything, everywhere. If you want big usable torque in a smaller and more nimble bike, then a twin is the better answer.

That's why I split the difference between big engine and small bike with a ZX-14R. Not a tourer, but not weak.

When I was 17, I bought a used single cyl 1968 BSA 441, and it was tons of fun. Was never able to kick start it even with the compression release lever and had it backfire my knee almost up to shoulder height...thank god I lived where there were lot's of hills so bump starting became the norm.

Fond memories of the sound though: the 441 was a awesome sounding thumper--the sound of that engine made me smile everytime I rode it.

I started on a Royal Enfield thumper and it was that sound that I loved. I even loved the kickstarting shenanigans that went along with it. Then, I got into a V-Twin and I'm on my fourth V-Twin now. I can't get away from the feel but really, it's the sound that keeps me here. It's funny about the one or two aspects of your bike keeps you loving it. It's different for different people.

There's also a factor of what you started riding or what kind of bike you spent a lot of your time on that will determine what you're going to end up looking for in the future. For me, I wanted the the low end torque of the single thumper over the two stroke smaller cylinder screamers that were available to me and that's what I am looking for now.

That being said, I spent a good week really wringing out a beautiful GSXR 750 and that bike was tons of fun. Still, I'm going to feel more at home with my 900SS Twin because that's where my mind calls home.

EDIT: Damn, I got all philosophical-like on you mofos.

So me wanting a sportbike with good strong torque down low came from my first bike the ninja 650r?

Why not? There's nothing like our first loves... unless it was abusive... and even then people get drawn to that type.
