I noticed that after I had my tensioners replaced and at same time the dealer installed a new oil pump, that my pressure still varies.
They told me that my crank runout was 3 thou and that was typical and not a problem. My old pump was scarred and had a groove worn in it.
My pressure will still vary after warm up. If I'm cruising it will usually cary 32 psi at about 2500 rpm. If I slow down and drop below 1200 rpm, of course the psi will drop as in any engine. But what is strange to me is, if I acelerate briskly back up to 2500 rpm by winding up to say 4500 or 5000 rpm, the psi usually goes back to 32 psi. If I put along and don't wind it up much over 2500 rpm, it will then only carry about 25 psi at cruise again at 2500 rpm.
I haven't had an oil pressure guage on the bike that long, so I'm wondering if this is typical for a twin cam. I also notice that sometimes the guage will wander up and down 5 to 10 psi while I am staying at a steady rpm. I know that sending units and guages aren't perfect, but I don't think this is that kind of issue.
I also have a lot of shake at idle and at 2000 rpm that I didn't have before the work was done. The bike runs and cruises smooth at 2500 rpm, and at say 1500 rpm in town it is smooth when I'm not lugging it. I try to stay 2000 rpm while riding in town. The dealer say's thisshake and psi flucuation is all normal?
Is this normal for twin cams? Any input would be appreciated. Thanks
