This motorcycle does not have any type of governor system.
Has the bike been sitting for a long time (ie; more than 6~12 months)? If so, then the carburetors are clogged with fuel varnish and need to be cleaned. A slow return to idle - as well as low power output - can also be caused by plugged carbs, low compression, and/or cracked and leaking intake manifolds.

If the compression is low (less than 140~160 PSI per cylinder), check and adjust the valve tappet clearance. If a valve adjustment fails to restore low compression, then you've got more serious engine troubles.

For your intermittant left front running light, try spraying some electrical contact cleaner into the turn signal switch. As for the rear units, they are turn signals only (no running/parking lights).

barb needs cleaning or a rebuild-itz 27years--varnish solidifies on the internal parts and passages and a strong solvent is required--carb cleaner will not work

check your cable it just might of slipped out of a hold down clamp! also check to see if it the cable is broke, if its neither one then the the pushrod release assembly probably broke! or if you take the cover off of the clutch assembly the pin and springs assemblies could have fallin apart!

depends where you live but in general it is 10w40 for 32 to 85 f. or 20w50 for 50 to 100 f. and NO full synthetic oil

here's a full list of parts with diagrams for your bike. good luck

are you sure you think its exhaust valves because i owned an 85 and i thought i had a valve problem too! if you've been abusing the bike and going past Redline i'm afraid i have some bad news for you..ten years after i had to get rid of my interceptor, i read an article by Honda admitting that they made defective cranks for their 500 interceptors, so now i know why my bike seized up on me going 60 mph on the highway..i quickly pulled in the clutch and coasted to a stop and then had to push it two miles home. what makes you think its an exhaust valve by the way? do you have a lot of smoke coming out, because that would just mean your burning a lot of oil that is getting through worn piston rings!

YES!! replace any line/manifold tubes that has a crack or leaks and if you want proof... take a can of carburetor cleaner (i prefer Chemtool B-12) and spray it over the suspected lines, while running of course, at idle and watch the rpms increase..then you will have found a loose or cracked hose or fitting!
Can i get a rating for this,
Thanks

Sorry, there is no quick fix. You will need the shop do a major top end job. Be sure they check the operation of the oil pump and that the oil is getting to the head.
