I've done this very combo on my 17 and my 19 and yes it's noticeable and worth it as its relatively an inexpensive mod.We use the axys quick drive belt with the pro ride gears
What gear ratio did you go with ? Did you notice greater track speed ?Used tki , I did not like the kurts ratio or the old pro pulleys. I wanted lower a lower ratio and the option of changing gears if needed. Plus tki has a tensioner which allows more teeth on the belt to contact the top gear
I am running a TKI gear down 2.52 gear ratio (25T top and 63T bottom). With this low of gearing, you have to run a steeper initial helix angle to help load the motor some off engagement otherwise it will feel very "zingy".What clutching do you guys run after gear down?
unplug gauge for 20% of your ridesI am running a TKI gear down 2.52 gear ratio (25T top and 63T bottom). With this low of gearing, you have to run a steeper initial helix angle to help load the motor some off engagement otherwise it will feel very "zingy".
I am currently running:
Primary-SLP Blue/Yellow 140/310
Boondocker 63g base with #14 capsule (may need more), hitting 8350-8400rpm
Secondary-Stock Spring with Derlin
I found that these sleds feel much snappier/stronger pulling ~8300rpm vs 8100rpm. I spent the beginning part of the year adding a bunch of weight to try and hit 8100 and the sled felt bogged down/lazy. As soon as I started pulling weight and getting the rpm up, it made the sled feel much snappier and revved quicker. Also felt like it pulled more on top end. I still need to get some more weight though with the boondocker weights. I bought what they recommended 63g base but I am running #14 capsule when they recommended the #10. I may need more as I am hitting 8400 depending on the snow conditions.
One down side to the gearing is my speedo is off by about 20% so I am racking up more miles that actual. Might need to figure something out there.
Thanks for sharing!Ive personally run the following combos and here is my quick input. Both are clutching and gearing packages I like.
Kurts gear down 32/67 and kurts clutching.
This combo provides a much needed drop in gearing while not going crazy low. I can say this is probably the easiest drop in performance gain with very little mechanical knowledge or skill. Bang for buck is really good, less belt heat. etc. Great mod for those guys who want better performance with stock like install and "tuning" needs..
TKI gear down 2.33 (27/63) TRS clutching. This setup IMO is very hard to beat for belt temps and flat out performance. It just works, pulls super hard and consistant all the time. That being said, there is more too it, both the belt drive and the clutching are more involved and require more setup (clutching espeically) Its also a little more specific for elevation. So like anything in life, that last little tiny bit of performance takes a bit more effore to chase down!
Regardless of how you get there gearing down is key (as is obvious from the new QD 2) that combo'd with some clutching results in much better overall performance and belt heat/life
