Hi, My friend's TTR has bad noise coming from cold engine only. Please listen audio recording from 7s: https://1drv.ms/u/s!Ar9YNbdz-p-shJpNFEbPR-5GBH0iBA We suspect automatic tensioner. The camshaft chain was changed last year. When engine is wormed the noise is gone.

Hi guys, hope someone can help, my ttr keeps blowing the 15amp fuse on top of the battery box, which then kills the engine. Change the fuse, bike starts, will do 100m, and fuse blows. Will tick over great, but soon as a bit of load.....fuse blows. Any idea's please? Thanks in advance, Steve.
