Hi all

Hope you can help.

I have a XTM Mammoth which is about 4 weeks old. Its had about 7- 8 hours use so far and has been great.

Today it's started to accelerate badly. It makes a crackly sound as it pulls away then changes gear after about a second. I know that when it was running correctly it was taking about 4 seconds before it shifted into second.

From reading the manual i understand that i can make the gears shift in earlier or later but I dont think this is the problem because of the crackly sound.

Please help!!!!!!!!!!
