Another shifting problem (I know, I know...)
Hi everyone! My name is Barry, long time rider and first time Vulcan 750 owner. I just got a 1998 with 25K miles. Pretty good condition but had been dropped low speed on her left side on dirt and grass, breaking the left headlight bracket, bending the headlight assembly and bending the shifter. Nothing major EXCEPT now after doing all the repairs and service to get her up and running again (she had sat for 2 months until I found her) everything is peachey but she will only do 1st and neutral. Now I have read everything pertaining to shifting problems on this forum going back to 2006 (geez, you guys are as old as me!) and I don't see my particular malady. So, she will shift 1st and neutral but whether on center stand or riding her I get full travel into 1st, back to neutral and almost full travel for second but she won't engage. It feels like there is something stopping the pawl from engaging the drum enough to turn it for a shift. Spring seems fine but after reading everything i'm beginning to think it might be the spring is just weak enough to not let 2nd engage. I don't think there is internal damage, the shift shaft has no lateral play, maybe 1/16 inch at most so I think the clips are still in place.
Could the PNF be a source of this? The three ball bearings I read could stick due to dirty oil, I have done an oil change but had thought maybe another one with added Sea Foam just to make sure everything is really clean. Would that process clean the balls (no offense) and possibly solve the problem?
And what about the clutch? Cable adjustment seems important, is there adjustments to make that also may help solve the problem? I don't have a Clymer yet so looking at service diagrams isn't an option yet.
I have had old GS Suzukis so I am very familiar with the quirks of our older bikes and have found forums like this are the best place for help and guidance. Any suggestions, advice, comments, bills of lading or dirty money is appreciated. Thanks in advance.
