The belt is measured in mm not inches. It should be replaced if it is more than 1 year old. They don't stretch enough to cause what you describe but they do get thin enough to reduce speed. This will NOT happen all of a sudden. more of a gradual loss. The contra spring can be tested on a bathroom scale. The stock spring should take 55-65 pounds to compress until the coils touch. Try a compression test (cylinder). My guess is you lost a valve seat or something similar. Also take a close look at the intake manifold. It is rubber ended,(at the carb) and prone to cracking. Have you looked at the Var?

My manifold split where the clamp goes around it to hold it to the carb. Think i had overtightened it and it cut into the rubber. It is hard to see sometimes as mine split underneath so i didnt see it till i took it off. I did have similair symptoms tho, i could only get to 30mph.

Well when mine went i had trouble getting it to idle too. Everytime i set it on the stand then reved it up it went haywire and needed set again. Spent ages turning my idle uo then back down before i finally took it apart and saw the split. Tried gluing it back up and taping over it with rubber tape but it only lasted a week like that while i waited till i got a new manifold delivered. Wouldnt have lasted much longer cos when i took it off i saw it was about to come apart again. New manifold was cheaper than my last belt tho so wasnt an expensive fix.

Might be something else tho. Take it you checked your fuel filter is clean?

I just posted on Blues other thread. The manifold issues you guys have had is an easy fix. Take the OLD/SPLIT manifold, and put it in a steel pail w/ some gas or acetone. I prefer acetone. About a quarter cup full. FUN TIME light it on fire. It will burn away the rubber casing leaving you with an all aluminum manifold pipe. You can now use any standard fuel proof coupler hose. You will need to use some elbow grease to peel it off but the fire hardens the rubber making it break vs. bend.

Here are a few picts of the manifold w/ the rubber removed, and one w/ a coupler used after.
