Title: terrible noise
Post by: gnvernon on August 05, 2014, 02:25:18 PM

The top speed of my 2012 2t was around 36-37 but I dont have the balls to get it up that high anymore because as soon as I hit 32 mph, there is a nasty sound coming from the variator. It slmost sounds as if it is clunkng. Any ideas as to what this could be?

I have yet to open it up. I took a video of the sound and posted it on youtube. It can be found here (https://www.youtube.com/watch?v=4iWEj_FZclE&list=UU4BwFgyOqIc2sAsoMZZ3Ksw (https://www.youtube.com/watch?v=4iWEj_FZclE&list=UU4BwFgyOqIc2sAsoMZZ3Ksw))

With all of these mods coming soon I dont wanna be stuck at 33 MPH! PLEASE HELP!!

I'd be afraid of you being stuck at 0 MPH with that sound and damage to other components inside that case. Why haven't you opened the case it take 3 mins to do?

I've been bogged down with work these last four days. Planning on opening it up today

Something sounds loose and metallic in there. Could be the variator or clutch nut loosening. Starter pinion and works would be a guess also.

Do a little research on whats inside that box, there is a bit that can come lose. You'll find some youtube vids and pics.

Sorry to thread dig, I bought a 2012 Super 8 2T about 2 weeks ago and it has been modified by the previous owner, only thing I can see is that it has a Technigas exhaust and it makes the same kind of noise yours does, its only does it above 60kmh and when taking off from a stand still and only when its warmed up.

Did you ever find out what it was?

Ive opened the case and have had a look inside but nothing seems out of the ordinary or broken, is it possible the belt is hitting the kickstarter pinion?
