Just a follow up to my engine vibration I had in my 04 ST1300. Today I gave the bike a service and changed over all the lubricants to PM Lubricants oils.
I used PM Motorlife Premium in the engine, and PM Diff gear life in the rear drive.
I took the bike for a test ride afterwards and noted that the engine vibrations that troubling me between 90 and 110 kph have all but disappeared, and gear shifts are a lot smoother than before.
On an altogether different issue I was reading up on the US forum about the stability issue with the ST1300. My 1300 always seems nervous on the highway in bad air. Nothing dangerous, it was just noticeable to me how much the ST moved around in a straight line, and that was always annoying to me. Anyway one contributor to the thread (who confessed he didn't own an ST, but knew a thing our two about getting bikes to handle) made a suggestion to wind the rear shock pre-loader right up and try that out.
Well I tried that out this afternoon and surprisingly the ride comfort was still pretty good, and it actually did make a real noticeable difference to the bikes straight line stability
So I'm chuffed that I have made two significant improvements to my bike with just a simple service and good quality oils, and by performing a suspension adjustment that I'd never have thought of doing if not for reading about it in the forum thread. Happier now with my ST than I've been since I brought it, and really looking forward to the ride to Yeppoon next weekend.
