I have had the 400 about 2 weeks now, I do have a question about sliders. What is the stock weight of the sliders and I see some people go to the 18g and some 19g. I would like to lower my rpm at freeway speeds. Will this cause quicker clutch wear? Love the scoot and at 300 miles getting ready to change oil to amsoil and also put it in the diff. Any comments would be welcom and I enjoy this forum.
Thanks

The stock 400 rollers are 26mmx13mm 19g (technically rollers slide but are round). So to easily differentiate the round are called rollers and the Dr Pulley are Sliders as they have angular faces.
Dr Pulley recommends dropping 10-15% in weight from original for their sliders. http://www.drpulley.info/drpulley_docs/Typenliste.pdf
According to some putting 19g dp sliders in drops the freeway rpms (with reverse logic, it's like putting in 21/22g rollers) but some like 18g dps for the improved acceleration.

Example showing the difference

THERE IS - NO -FREE RIDE......!!!!!!!!!! What you gain on one end - you lose on the other end.!! Lighter weights cause the transmission not to "shift" to lower RPM on accelerating from a stop - therefore decreasing fuel mileage AT LOW SPEEDS...!!! And maybe making it up - when you are cruising on the highway at around 70 MPH...... BUT not much.....!! I have the 18 gram DPS sliders and now my overall MPG is just about 55 MPG!!!!!!!!!! With the stock rollers - I was averaging about 65-70 MPG..... :( :(

I have just serviced my K8 400 and installed non oem cheap 26x13 17.5g rollers off fleabay and my full tank to full tank mileage is still good at 71.9 mpg. However I did also clean my K&N filter with their recharge kit, so may have also greatly helped.

report on changing out rollers to 19 gram sliders, everything went well thanks to this board, I changed them and my oil and diff oil last week. the ony problem was tightening the pully. next time I will have the right tool. The sliders did what I wanted them to it did drop the rpms cruzing at 70 on the spedo, but actuly only 65 mph, (will work on that problem next.) I think the gas milage has stayed the same but that could be the type of driving I do. My only concern is when I drained the rear diff the oil was very thick and had grey clouds in it. I will change it agan next time I change my oil. All and all things went great and the scoot runs great. Thanks again for all your help.
