hey guys i just put my blaster back together after rebuilding and its not the first one ive done but the most complicated, first after getting it together all was good riding it around then decided to rip through all gears on the back road by my house get almost to the top of the hill and it dies and wont start, i then turned it around and pop started it and made it back to the yard, let it set for a day or so and today i went out started it up and it revs up good sounds mean but yet doesnt have any getup what so ever and i noticed the chain was loose so i adjusted it and pulled it back and tightened it up made one lap around the yard and it dies and i noticed the chain was saggen horribly is that what causing it not to have any getup or is it in the clutch at times it feels like its slipping but after checking all the disks and plates out they were fine any idea why it keeps dieing and no get up? i do have a aftermarket exaust its a fmf fatty i just put on there and currently no air filter just open carb for the moment since this was the trial run for it.
