The reason why I ask is that I live on the West Coast of British Columbia surrounded by the Coastal mountain range. One reason I haven't gone to sliders is the drop in rpms at highway speeds. That's the last thing I need.

Before I got a new CVT belt at 21000 km I noticed a curious thing with the old worn belt. At a level cruise the rpm's were about the same as always. However on big hills I had maybe 300-400 more rpms and the difference in performance was HUGE. The bike could accelerate quickly on hills when running at speed, where it couldn't before.

That experience taught me that even a small increase in rpms under load compared to stock; makes for an outsize difference in performance and a much more responsive fun bike.

If the sliders can do that they would be the cat's meow.

That's exactly what will happen, but not because they're sliders, but because
they're lighter.

I had the same exact thing.
5500-5600 WOT revs stock, about the same up hills, maybe slightly less.
With 10% lighter sliders, I got 6500 WOT revs, and never under 6000 going
up hill which is still at least 400 revs more then I had before. As you said,
the difference in this range is HUGE.

My scoot has it's peak torque at 6500 revs so the difference between
5500 and 6500 revs was huge. It made the scoot go 2 seconds faster
0-60mph too (from 11 to 9 seconds!).

Bare in mind that even if you're cruising at 65mph at lower revs then
before, WOT will result in MORE revs then stock, while your stock bike
might remain at same revs and not even accelerate over 65mph at
the incline. Been there, done that. Had 30hp on tap, couldn't use more
then 23-24 at 6000 revs.

I've went on from the 6500 setup to 8000, then backing it off to 7500
and now 7000, 2 different variators, multiple combinations of regular
weights and sliders. The sliders win in every single match, you just gotta
find the correct weight, and if you want more WOT revs up hills, you need
lighter weights.

HOWEVER, what's keeping the revs lower then they should be going up
a hill in too tall a gear (so to speak) is a weak contra-spring, which you can
swap out too, but that's like going from a "drive" to "sport" mode in an
automatic transmission car.

You'll have higher revs even when you don't want them.

Try dr pulley's first. Make note of where the engine revs are at WOT, and
at low and high cruising speeds. Get 10% lighter sliders, take notes again
then drop me a not and we'll compare.

If your responds similar to mine, I'll be able to tell you how it would be
with more variations of the slider weights and/or with a malossi multivar
with regular rollers OR sliders.

I've spent a lot of money on experimenting.. but bottom line is.. 10%
lighter sliders gave me 90% of performance upgrade that I have now
for virtually no money.

The Malossi CVT was $300, and I'm on my 4th set of weights in it right
now (went from 20 to 25 incrementally).



Bottom line - aim for the peak torque revs or slightly above at WOT.
You can try out cheapo rollers of different weights to determine which weights you
need, then just get sliders of the same weight and you're done.

You'll be able to do lower revs then stock with sliders up to 20% lighter then stock round weights.

I hope I'm making sense here.

Ok! Surfing the net yesterday i stumbled upon an kymco xciting 500 which had an great price. I know that it is not what i was asking about but any info on that? It is an 2006 model. Mister Cortez Sir?

Yessir, very familiar with that scooter.

Very heavy, probably as heavy as it gets in that class, I believe it was rated
at around 525lbs dry, and rather sluggish up to 50mph (250cc performance).

It was also very thirsty if it's not a fuel injected model, and in 2006 we
didn't have F.I. on the XC500.

The pluses are an extremely stable ride, very confidence inspiring on open
roads and holds it's line well in high speed twisties. It's virtually bullet proof.

THe minuses.. well.. it's got 400cc type performance because of the weight
and it reacts well to CVT tuning. Fuel consumption mentioned already,
people locally are getting about 40MPG, or worse in urban enviroments.

The F.I. is slightly better and slightly faster.

It's also a pig around town, much like a Majesty 400, only worse. It refuses
to change direction - takes some effort.

EU model had linked brakes, they're great, very hard to lock up the front.

Spec sheet says 89mph top speed, and the speedowill happily lie up to 110mph.

Bottom line - slower then most 500s, thirstier then most too if not FI,
and built better then some. Roller weights and belt costs more then for
italian scoots, and lasts longer then all of them. Brake pads also last up
to 30k miles (hard compound).

Best of all, it's probably gonna be the cheapest 500 you can get, and it's
made to last unlike some more expensive options.

I could live with it.
I would have owned a 500Ri w/ ABS if it wasn't sold right before I sold
my Kawasaki. Didn't want to wait for another one (3-4 months) so I
got the DT300.
