Front brake wont build pressure

your crank case oil lubricates all of your internals including your clutch pack! if your crankcase oil is full and you clutch doesn't work still drain you oil and remove the right side crankcase cover that is where your clutch pack resides remove the clutch basket and check the clutch pack plates for ware they may need replacement! Empty your gas tank and start with fresh gas good chance your carburetors are gummed up from stale gas which will make it run rough and usually loose the ability to idle! as for your font brake check to make sure the master cylinder for it is topped up with fluid is so try bleeding it if after bleeding the brakes no improvement is noticed remove the front brake assembly pull the pads off and check to see if there is any movement in the calipers themselves they may have seized from sitting! and there is no honda virago, virago is a yamaha and i think if u have an 82 xv its a yamaha virago

your fluid is contaminated with water.u need to flush it then put new fluid.and make sure you bleed the brake.

Your brake hoses are collapsing internally and holding pressure. I've seen this multiple times, especially on Yamahas. Replace the brake hoses, flush the system and refill w/DOT 4 fluid, bleed the air and you'll be good to go. Good luck!

check fluid level, place a rag around brake pipi and gently compress pipi with pliers or vice grip check if pressure present bleed at bolt(pipie to master cylinder) if pressure present bleed further if not replace master cylinder kit

I had same problem, i ended up reverse bleeding it with airline at work. Regulated pressure down to about 5 psi, then attached hose prefilled with brake fluid between bleed nipple and airline trigger and gently sqeezed trigger till fluid came out in resevoir.Helps that i work in a hose distributor and have all the hose and fitting to hand mind. hope this helps
