Yamaha SH50 (riva/razz) running issue

by (no login)

 

HI! I have a Yamaha SH50 (Says Riva on the front, I believe it says Razz on side panel, it's under a cover b/c of snow). Anyway, thanks to help from everyone here, I cleaned the carbs, pushed wire through the jets and got her running. The battery is presumably completely dead (it sat for years without so much as being started). The engine w/ choke will run and she warms up. once underway, she's fine but pulling to a stop, she'll get really low on the RPMs and the lights go dim. I have to fuss w/ the throttle and choke (adding just a little little "hair" of choke) and she'll continue but sometimes she'll just cut out completely and I'll have to kick her starter a couple of times to get her going again (note, generally she doesn't re-start on the first kick but don't know if it's the *$#&*$ cold or something else). Any suggestions as to what it could be? I'd like some specific ideas before I pull out all the plastics again so I can go straight to the general area of the problem. (Or could it be the battery? I never bothered to get a new one as I thought the battery was only good for the starter and powering turn signals at idle). Incidentally, the turn signals just stay on with a "spastic" pulse at a stop but blink fine on full throttle.

Thanks in advance !!!!!

John
