The video shows a max of 65, but on a warmer day, I've cruised at 69mph and hit downhills at 72-73mph. I think I had some headwind in the video, and since I'm so light, the wind makes a big difference.

Drove home today. Steady 90mph. 120 to 140 mph at times aircon on, full leather, cruise and radio 2/4 Trip computer says av of 32.6 mpg. That's half a Forza in mpg and nowt else. Result

Let's think about this. I have heard of the spacer being used if belt chatter on take off develops after installing Dr.Pulley sliders in the stock variator. It is because the design of the sliders allows a lower gear range for quicker take off by allowing the inner pulley to slide inward farther than stock which lets the belt drop down farther into the V. If the gap becomes too large for any given belt, the belt will not be squeezed between the pulley halves until the engine revs up enough to start throwing the weights out. I haven't needed it so I didn't try it and don't really want to spend time taking my bike apart to engineer a fix for a problem I am not having.
.
But any spacer on the inside or outside of the boss which sets the location of the outer pulley will move it out and will make the chatter worse. The front pulleys need to be kept closer together at low range. Any spacer would have to have an i.d. to fit over the boss and be installed between the ramp plate and the inner pulley along with the weights and be the correct thickness to provide a new stop for the inner pulley. It would also be best to install it with some Locktight or something in order to stick it to the ramp face so it is not rattling around loose on the boss the whole time you are riding.
.
Image
To bring the outer pulley closer to the variator, I would:
... shorten the boss (3) and add spacer(s) behind ramp plate (6) and/or by spacer (7).

I still need to check the situation. I plan to:
  • 1. Run WOT with rear brake pressed to keep gearing and speed low (eg: 30km/h). Check how low the belt sits in the V.
    2. Run WOT without brake to rev limited top speed and check where the belt sits in the V.
Then I will know what to do next. eg: shorten the boss or modify or replace the outer pulley.

Grrrr, my sliders flew out of Taiwan on 9 Dec and now I have to wait for SA post office... I was hoping to get them before Christmas but I won't hold my breath.
I'll be lucky if I get them before Christmas next year. o_O

Machining the boss #3 would cure any possible chatter and also increase the top gearing as it would force the belt all the way out to the unused portion of the pulley.

11.5g Dr Pulley sliders from Ebay.
I just wish that they would arrive before Christmas. I'm going on a road trip on the 27th.

Feedback looks ok. I don't normally order from the Far East as there are loads of copy's about but we will see how it goes.

They are coming from Taiwan so I might get them for the better weather next year....
I've received mine yesterday. 11.5g and it runs at 7500rpm.
Lowest gearing is slightly higher as the variator opens 1mm more in lowest gearing.
Top speed remains the same. Perhaps I am the only one who experienced a decrease in gear range.

I bought mine off ebay but it may be better to buy straight from the supplier's website: http://www.exportstrength.com/index.php ... _8513_8777

Ok, my question may start a firestorm, but..... between a Yuminashi and a Takegawa, which is better for higher top end? To go with that, sliders or rollers? Which weights will give good accelleration, since it would not be good to try to merge into traffic if the bike bogs down.

I had 10g sliders in but took them out and put the 13's back in as I thought it revved too hard when accelerating. The fuel consumption was lower as well. If any one wants them in the UK they can have them for the cost of the postage. PM me. First come gets them.

3 mph is good because it would get my bike to a true 70 mph. Then, if I changed the variator it
might get me a good top end at or above 75 mph....hopefully above. Every little bit counts. However, if I can get the same thing with just changing the variator, that would be even better. :? Maybe???

Yeah the dial calipers were to see what size the nut was for variator. But the makeshift tool worked flawlessly. It's gonna be burnt though cause it is the core of a pine tree so covered in flammable sap
