Does gareth need to get a new bike?

[Dave-]

gotta love those aprillia swingarms...

He just put $30 into savings... only another 999 deposits to go!

[Crasherfromwayback]

Chubby inducing!

[AlBundy]

That sounds awesome!!!

[AlBundy]

Chubby inducing!


Indeed......

[Drew]

Chubby inducing!

But you're easily induced.

[Crasherfromwayback]

Aye. This cold weather is taking it's toll though.

I hear that, no where near as impressive with sub zero temperatures!

Oh gawd.

Reckon the RSV-4 looks great... little bit Japanese IL4 like, but not as much as the 1098 at least. Be good to see in road trim, and race livery for that matter. Sounds ok on my laptop too, but almost anything does.

I remember when honda had the V4 market cornered now everyones making one :whistle:

Pity they gave up back in the early 90's with the sportsbike... would have been mint to get a race tuned VFR750 in modern form!

[vifferman]

That sounds awesome!!!My bike sounds a lot like that with the restrictor out of the zorst, but it gives me a headache, not a chubby.

Mmmm, I think you should give me your bike then, since you obviously don't have as much appreciation for the sound, lol...

Call Carver - I know he shares his...

More juicy goodness!

Check how narrow the engine in is in this video.

You get a good look at after the 52 second mark.

Makes my 400 v4 look pretty big and silly. Mind you, that design didn't change all that much between 1986 and 1998.

Now what are the chances that ALL of the Italian words that LBTW knows can literally be put into one sentence? (and then some extra non-iti) ...

He never rode a VF750 for long then, not sure if there are words to describe that motor, other than FUCKED if you didn't have the valve clearances perfect, and the best oil on earth changed daily.

My NC30 treated me well for a couple of years.

My NC30 treated me well for a couple of years.Without bothering to check my references, I think one of the problems with the VF series was the cam chain tensioner. So away it went...

That's just one of the problems. The cams and rockers would eat themselves in no time at all without more maintenence than ride time. Went bloody well when it was going though, and it only cost me a bottle of bourbon.

Cam Chain?

Isnt that what gears are for?

[Drew]

Even Honda have caught up with the times and use cam chains now. The gear idea limits too many things. Ya cant bump compression without shelling out for high comp pistons, bloody honda over technicalising shit.

Horses for courses dude, gears are generally good for more revs, so if that's a big part of the design criteria they might make sense.

I see Buell's new rotax is chain driven to one cam which is gear driven to the other. Means the chain path is straighter, with a simpler tensioner required, cute.

Fair call, the gear driven second cam idea is a good one, acuracy would be the only issue. An easy tuning method is to have cams "dialed in" on most bikes, since tolerences on mass produced bikes tend to be a tad different, harder indeed with gear drives.

A little bit like a TL engine then?

[EJK]

You know some people say "My bike sounds like a Ferrari!" but which isn't? Well this one really sounds like a Carrera GT which I like! :shit:
It sounds very.... aggressive. :love:

[Sully60]

Then you should hear a Honda(I know:rolleyes:) Valkyrie with a Two Brothers six into six exhaust.:headbang:

I'm sorry but the April Irimera just sound like a VFR800 with a loud pipe. Why not be different and give us a twin pulse engine like the D16RR?

[Ocean1]

Didn't know that.

Quite a few innovative bits or yer TL.

You still aint brought yer Buell up for me to bounce on either fella!

[Ocean1]

I have not. Will do though, bit happier with the front now.

[Sully60]

Some are still with us but others, well:whistle:

I could think of better trampolines dude:)

[Drew]

Like yours?




I could think of better trampolines dude:)But not as classy.

[Sully60]

Like yours?



I was referring to the various innovations that appeared on the TL, rotary dampers are such an in thing right now huh?

But you have a point there.:sherlock:

[EJK]

Then you should hear a Honda(I know:rolleyes:) Valkyrie with a Two Brothers six into six exhaust.:headbang:

:shit: Bring it! :headbang:

[Sully60]

Consider it brung!

I got "Il Primo Quattro". No shit mate, that's a primo quattro if ever I saw one.

I understand the gears were a response to big bang engines eating whatever system was being used to drive the cams. The force required to open all those valves at once is more than the regular amount of force that is required of a cambelt than that operating the camshafts in a regular firing order.

But kinda retarded because the VFR400s, RVF400, CBR250RR (And CBR400? Dunno) were never big bang anyway. Nor the consumer targeted VFR750s/800s. And then there were the SP-1/2s, which were also gear driven.

Maybe it was just some weird 'racing heritage' shit marketing forced on the designers? Or perhaps somewhere, hiding in the most secret bowls of HRC are all the bits needed to convert these engines, and available if you know the part numbers.
