new and improved!! these now come with the a weaker YELLOW spring! this is better suited for 50cc high rpm setups. new photo soon to come

doppler engine tension spring for av7 and av10 moby! this spring is much easier to use and provides a ton of adjustment for getting your variator dialed. av10 and av7, unfortunately only comes in red YELLOW so you can't match it to your bike, sorrrrrry.

looks pretty mbk av10 specific but probably easily usable on av7 too if ya like, someone tell me

if for some reason you want the stiffer red one, it is available separately here

5 of 5 Fits with the Sim pipe! December 31, 2012

just barely fits with the Sim (pires) circuit pipe without modification, but be prepared for possible centerstand interference on the 40t

4 of 5 Mod for AV7 April 20, 2011
taco eater : mikeboyd from sf to austin  
To fit these on an AV7 you'll have to cut the four front engine (pipe) mount brackets on this spring so they are flush with the plate they are welded to. You will also have to add one washer to each of your stock mounting bolts on the rear mount.
