honda forza 300 - help from Italy!

[dasshreddar]

Hey BRed
I've been using the 20g sliders/15g rollers since you recommended them... they work great
especially like them uphill(steep)... 55mph full throttle(stock) now 61mph
please let us know if the "2418"s are better

[BRed]

Excellent!
Thanks for the feedback!

It's interesting to note that one of my local test points is a steep 1/4 mile uphill grade.
I stop at the bottom, accelerate hard and check my speed at the top.....
I get about the same results as you.....55mph max stock, 62 mph w/ mixed weights!

How is your fuel mileage?

[dasshreddar]

fuel mileage seems to hover around 68(average)
mpg readout is usually 66-71...

Ed in these mix set up:
3 20 gr sliders and 3 15 gr rollers
3 19 gr sliders and 3 15 g rrollers
3 20 gr sliders and 3 16 gr rollers
3 19 gr sliders and 3 16 gr rollers
Do you know for every combination, the acceleration time (0 -100 km), and the max speed?
thank you
Robert

[BRed]

Robert, you've seen the video of 20G sliders/15G rollers so that gives you a reference point...
that combination will do 0-60 in ~9 seconds.

either of the 19 G slider combos will be about 1 second faster to 100kph (60mph)...

all 4 combos will probably top 87mph (my personal max speed on a new low mileage Forza), but the heavier sliders will have a lower rpm shift point rpm at take off and the heavier rollers will have a lower cruise rpm.....
the lighter slider combos will probably take a few seconds longer to reach top speed.

this is all assuming those weight configurations were being tested on the same bike with no other mods.

When I get some Veypor runs for the Forza, the average of many runs will show actual peak torque and peak HP rpm to the rear wheel for the Forza and may indicate the need for a slight tweak in weights for one or the other type to fine tune the curve.

I have ordered the 23x18 19g Dr.Pulley sliders and JMT 23x18 16g rollers, hope to give some input about the outcome of this combo next week.

0-100 in 8 seconds sounds

[robertinino]

Ed

[robertinino]

Robert,

I keep you (and all others) posted

Is it clear to you what combo to mount and when?

Greetings,

Mario

mariomario after what Ed said to us, I finally decide to try your combination 19-16 grams.
If you don't use the 3 rollers and the 3 sliders you'll can send them to me and sharing the costs of purchase.
Rollers seem to be of good quality...

... let me know

Robert,

That's ok by me, I payed (including two time's shipping) a total of €78,13

Don't forget you also need the Tool to lock the front fixed pulley (Buzzetti 5554)
http://maksor-scooterparts.com/buzzetti-4322.html

And a torque wrench to mount the bolt from the front pulley back on with 83nM

I am also trying to get Dr Pulley Slide Piece SP2418 K but they come in 4 pieces so you are on your own for that one.

Greetings,

Mario

[robertinino]

mario,
hard acceleration between 8-9 seconds seems to be a dream.....
thank you very much for information about purchase tools. I'm afraid to do the work for myself but if you help me with a tutorial and photos everything will be easy.
Thank you again for send to me rollers/sliders, ok for the price+ the cost of shipping everything to me.
In this forum there is a section for messages, look at this, i'll send you information about my email so you can put in contact to me for my address
ciao Mario

Mario,
for 2418 I'm waiting more information from you and Ed......there is still need to search

Robert, I think you are confused with the Dr Pulley Slide Piece SP2418 K, they are no sliders

http://drpulley.shopnix.de/product_info ... ucts_id=36

[robertinino]

yes i'confused...
but look at what Ed said about dr pulley slide:

..........I would only use the original 3 OEM Honda sliders, since every time I've used the DR Pulley sliders, they cracked and jammed up the variator, causing it to hang in one gear while shifting....this usually happened after several hours of highway riding.

The DR Pulley sliding weights are excellent but unfortunately, their sliding bearings suck!

[BRed]

Yes, on the DRP sliding bearings, they only seem to hold up well in the DR Pulley variator.

Twice I've tried them on Honda variators and both times they cracked and locked the variator.....
they are made of a different light colored plastic compound that seem harder and less flexible than the Honda bearings. They fit the Honda variator very loosely.

If you're concerned about drag on the stock Honda sliding bearings, you can always touch them up a bit with sand paper to polish the surface and add some clearance.

and then there's the confusion caused by two closely related parts with the same part number.....2418?!

[Mario]

aha, missed that one!! but just in time because I almost ordered them

And thanks Ed for the perfect (again) info

[BRed]

for the record:
the sliding bearings for a 23x18 variator are SP2418

the Helix style sliding rollers are SR2418
these are 1mm taller and will be like overdrive weights for the Forza

[Mario]

Ed, is it correct that the bolt from the front pulley needs 83nM ?

[BRed]

I'll check that in the service manual when I get home this afternoon.

I seem to remember that the variator bolt for the Forza actually used less torque than the variator nut on the older 250cc series.....
the Forza's bolt has much more thread engagement, maybe twice as much as the older threaded shaft with a nut.
