Since GEH apparently is refusing to give us the straight 'n skinny on his new Koso variator, I thought I'd do so on the El Cheapo one I got thanks to his link (~$20 or $25 including 9 weights). First: this thing either is a Russian product or was packaged for sale to a Russian retailer. The web site on the package is a Russian site selling this exact thing. Next: The glide (photo below; black one on the right) I did NOT use. The OEM glide is shown next to it (on the left) does NOT have the ridge at the bottom of the slide fingers. The Dr. Pully I am replacing also had this ridge - and it tore up my sliders within about 500 miles. So I'm using the new El Cheapo with the OEM glide.   FINALLY FOR NOW: It's clear I need to add a spacer (to lengthen the boss) since from stopped accelleration sucks (belt is not seating all the way down because the two variator faces are too close together. What pizzes me off is the Dr. Pully came with a little baggie of 3 shims that I never used - and now i can't find them. So will have to order a bag of shims - shipping cost is twice the cost of the damn shims! So I'll end up with a dozen or so unneeded shims in case anyone else needs any. Here is the variator installed. Have not yet checked top end - later today  |

Is the new boss the same length as your other ones , even check the stock boss . if you can take a pick of the new variator laying face up so I can see where the boss is inserted that would be great.

From what I can see from the pick , the face looks pretty clean ! , as in no imperfections , nicks or anything. You would not be impressed with the Koso's , many have imperfections and nicks on the face. And the back plate is the exact same . I'll take a pick of my new back plate and show you . Can you weight the variator for me also ? |

Here is a first update on "el Cheapo", the Russian variator. First, originally had really bad off-the-line pickup with el Cheapo and was going to add shims. But then I looked at the Dr Pulley driven face (outer drive face) I had removed and noticed it had a "lip" that would do the same thing as a spacer. So I took the OEM driven face off, put the dr pulley driven face on and the pickup was pretty good. Not as good as with the dr pulley variator - not quite - but, then, i had three 8 gr and three 10 gr had rollers installed instead of the six 9gr sliders I had with the dr pulley. So tonight i put the thing back together with the sliders for an apples-apples comparison. Here is a photo of the dr pulley driven face next to the OEM driven face (dr pully MUCH lighter in the fin area):   Second, the ramps of el Cheapo were coated. That is ~~~ WERE. After only 50 miles the coating is wearing off of the ramps (must be paint, not teflon):  "el CHEAPO" is right ! Third - notice the outer distance the belt went compared to the dr. pulley variator with the 9gr sliders:  So, anyway, in the end all I did was to remove the rollers and put in the 9gr sliders for a head-to-head comparison. Come on, el Cheapo - show your stuff! |

Also use the back plate that came with the new one. Your belt drops much further then in the koso I have ! Next see what rpm you top out at with the weights you are using. If the weights are too light you will not get good climb on the variator . did it seem as if the rpms were too high or not ? Also if you do not take her on a top speed run you will not get the climb out of the variator .

Also if you do not take her on a top speed run you will not get the climb out of the variator . RPMs may be better with the 9gr sliders, but with the rollers they were crappy again. If you remember, I've been having RPM problems all along. With the dr pulley I was not able to get above 7400. Then when I put the (smaller) OEM variator in it was in the mid to high 7K range. This morning with the el Cheapo & rollers I was back under 7K. ps: I DID get high speed this morning before taking the photos --- 65mph going down a hill. So the highest belt travel is really the highest belt travel. |

So the highest belt travel is really the highest belt travel. I wonder if you have bad tranny bearings ? Or bad axle bearings ? Something is holding you scoot back. With a new belt I used 9.5 gram weights. As the belt wears my rpms rise and i have to go up .5 grams every so often or the belt will not climb on the variator . I was up to 10.5 grams whenever I got the new koso and starter clutch. After changing the S clutch and installing the new koso I'm at 11 grams. I need to buy a new belt to see if I still need 9.5 grams at the beginning . what brand belt do you have ? Did you ever measure the width ? If the belt is too wide " never seen that before " your rpms will suffer . |

Also I see in the pic that the inner part of the new variator " el cheapo " is just like the koso . where the boss slides in , it looks like the variator face should have been turned down more . that's what makes the belt not drop fully .
