Question about 2007 Suzuki DR-Z 400 SM
Sounds like carb freeze, wont rev up, just makes a lot of noise. its not carb freeze, have taken carb off and checked it over and everything is ok. taken the head off to see if the cam chain is causing the problem, but its not its fine. the bike is also very hot after about 2 minutes of running, can not hold hand behind exhaust because its burns after 2 minutes.
think now it maybe the cdi unit under the seat.
hope somebody can help
Hi m8,, if the motors running hot thats usually weak mixture if the spark plug is white on the end, then ,will be running weak ,,or timing is a little out ,, try a timing light strobe first be 4 ,checkin the cdi, put a bit of white tippex or paint on the tdc mark,, wen u point the strobe at timing marks ,the white painted mark should be in line with the pointer,can adjust the backing plate of the coil pickups accordingly, cheers
