Suzuki Boulevard C90 - Answered Questions & Fixed Issues

Question edited for clarity, add Maker. Question moved to Make Model category. Insufficient clutch clearance. In the old days, it was a badly adjusted slack chain. ..

Your starter button is a two position switch. The lights are supposed to go dim when the button is pushed halfway in. When pushed in all the way it should activate the starter solenoid. The starter solenoid is located under the seat next to the battery. You can follow the positive battery cable directly to the starter solenoid. If you push the starter button and the starter solenoid clicks, then the starter button is good. If the you unplug the two smaller wires going to the starter solenoid and connect a voltage meter to the main harness leads , the needle should jump whenever you press the starter button. If it does not clean the button contacts or replace the right switch assembly. If the starter button is good then take a jumper wire and short across the two battery cables on the starter solenoid. This will put power directly to the the starter. If the starter works now replace the starter solenoid. If your starter still does not work, try holding the starter button and tapping on the starter with a plastic hammer. If the starter works now then you probably need to replace the starter brushes. If anything else is wrong with the starter you will need to replace the assembly as the dealer will usually only offer the starter brushes for repair purpose.

no. At idle teh alternator is probably putting out less volts, At higher idle you should get higher voltage charging the battery, lights should get brighter.

Try putting the bike in gear when this happens and rock it until you reposition the pistons, then hit your starter and see what happens. ( If you are up against the compression stroke, then you wait a few seconds it gives it time to bleed down the compression.)

Have you checked the safety switch on your kickstand?

A SWITCH NR THE REAR BRAKE LEVER, NEEDS TAKING OFF, BUT COULD BE IN NEED OF A CLEAN AND A WIGLE WITH WD40

you need to do a check, under rear seat a small white plug, might have a black end cap, it has 2 terminals u need to use a wire bent and pushed into the terminals, then turn engine on and a code will come up on dash, codes are in the manual. good luck.

is side stand down??

generator behind casing. buy a second hand one, what bike.

try clutch adjustment, at both ends, read manual follow manual

make sure the terminls on battery are secure.

SHOULD BE A DRAIN BOLD IN THE BOTTOM AND WILL NEED TO PUMP THE FORKS WHEN EMPTYING.

check clutch and side stand safety switch

the spruage bearing mabe bad

stamped on bottom of main crank case near starter motor back of cylinders

It will be stamped into the engine cases, on sv650''s it's on the left lower part of the engine and on some gsxr''s it's on the rear of the engine for example

with engine running you should be able to check alternator output on the battery. put your leads on the positive and negative post and see if it reads more then 12 volts DC. usually charges at 13-13.5 volts

Check your rear brake master. Is there fluid in the reservoir? Have you tried bleeding the system? Does the operation of the pedal actually make everything operate as it should....is it all connected as it should be? Might require a strip down to replace seals etc. Sorry if none of this helps.
