Odd Losi bit! the 86 and 88 spurs have 23 tooth belt gear, the 90 tooth has 20 tooth belt gear, the xxx4 is a 20 tooth belt gear. Have not checked 64 pitch. Wonder why Losi did this!!! Sure screws up a FDR!!!
Josh's belt fit OK with a 90, had to do the adjustment to the chassis slot with a 86/88.
Does not compute!
I have a 90T Losi Spur w/ drive pulley in my hand and the drive pulley is 23T not 20.
I have 4 of Josh's belts. They are one tooth too short and therefore when installed are too tight and make a ton of noise when trying to run the car. Ive made the chassis mods he suggests but still cannot get the belt to have enough slack. Ive even gone to changing both the front and rear diff pulleys to the smaller diameter versions and still cannot get enough distance to make up for the shortness of these belts. A 20T drive pulley would probably make it all come together but I don't know if they really exist??? Any suggestions? Or a source for a 90T/20T spur gear? Thanks.
