slow RPM to return to idle

Postby uptonch » Mon Mar 16, 2015 3:53 pm

I really have two problems and I don't think that they are related, one is bring the RPM up to about 3k back fire on the right side suspect the # 3 cyl. due to color of sparkplug. problem #2 bring RPM up to above 3-4k and back to idle sometime it takes about 15-30 seconds to return to idle. when riding have to use the gears to slow it down on a stop. bike has been setting for about a year it started up real good but have these problems. any help will be appreciated.
I posted this and did not say what it was,it's a 1976 GW and I have had this thing for ever it seems since 1980. and setting in my garage since 2000 and had some work done on it in 2010.rode it a couple of times and has set for the last year.
this is my first post on the forum so I hope that I'm doing it right. I ride a HD ultra trike, but now and then I like to get back on two wheels.

If the carbs sat with old fuel in them then you may have air jets or slides clogged up. The slides have to work very smooth with no lube. There is a great video and book available to help with carbs or there are a couple outfits that do great work also.

Regarding brakes, sounds like maybe stuck calipers but then they would be hanging up when riding so need more detail.

I'm not up on the 1000s, but the throttle seems to be sticking causing the slow return to idle. Have you tried to lubricate the cables? And somewhere in there, there must be a return spring. Like I said, I'm not up on 1000s, but hope I can help some. There are lots of riders that are familiar with them, so don't fret. Someone will come along who knows then inside out. Did you look through the 1000 sections on this site? Your answers may be there.

Some sea foam might not hurt to clear up the carbs

This can also be caused by carbs that are significantly out of sync, or an air leak in the intake system.
