Hey guys I just took my cub out for the frist trip and after the first day of riding the next morning its was really cold and i have a noise coming from the motor and its kind like a card in the spokes king of noise that goes faster and slower with the rpm range tell the motor heats up is this just the pistons needing to warm up or any ideas. It goes away as soon as the motor is good and warm and it runs like a monster and I road it the hole day with no proablems.
why i suggest that is because I had a buddy whos bike made the same sound at the dunes and it ran fine went away and would come back ,well it ended up being the finger nuts and it tore alot of stuff up once it worked its way off!
doesnt mean they wont work loose,,I gaurentee they can!! Ive seen it! just check those and make sure there tight...it might be your water pump or gear making that sound as well...do you have a billet pump?
