Hello everyone , i have a dragstar 400 for quite few years now ,still i never found a repair manual for it , only the manual for the 650 ,very similar bu yesterday i wanted to start the bike ,the engine turned over like 1/2 or 2/4 of a turn and got stuck with a <clong> noise , my guess is a valve stuck opened perhaps i will have to investigate by opening the valves covers but does anyone knows if the valves are the same size for the 400 and the 650 ??? i'd like to believe that cylinders are the same size, consequently the heads are the same as well , piston bore probably smaller and perhaps crankshaft different as well. So where can i find a manual for the 400 ?? are the valves same size for the 400 and the 650 ?/ Thanks for your help , Claude.

Hi, maybe a bit late to answer to your battery problem but when i bought my dragstar 400 (second hand) ,i always had electrical problems ,would not charge well, difficult to start , ... i discovered that i had corrosion in the regulator connector,this regulator is really not installed at the best place ,right at the back of the front wheel,he recieve all the water he can get in bad weather; i replaced it with a new one in a new location, i installed it under a solo seat on springs so i have a lot of clearence, on top of the regulator i fixed a small 12v electric fan (the one used in electronic and computers) it goes on as soon i turn ignition key on, consume nothing ( 0.03amps) , perfect place , always dry , since ,no more problems ! So , Check well all your connections, especially the one on your voltage regulator, Cheers.
