    You might need to service the steering head & swing arm bearings,the front forks also.

    On the Highway my Old Modded GS 1000 could easily turn 12,600 in 5th gear plus, (Usually too bust steering to watch it very closely) Stock gearing, the Speedo would be down at the Letter m in the mph thats on the speedometer so I figure 140 mile hour plus Easy.

    HA HA Hey Guys RPM.. at least on that crappy stock Suzuki Tach. I was amazed it revved like that but had a LONG Highway to do it on. I took it back in the eighties to the track, Im 240 plus, without any front lowering no struts or even letting air out of tire It ran 11.20 at 125 with my fat arse on it. This was a lowly 1000 Modified a Lot . 29 Smooth bores ported Head cams valves springs but stock valve diameter, lobe centre 110 degrees, manual cam chain Tensioner, welded crank and clutch ,, Oil Pump Gear mod. (750 ones) Undercut and welded Transmission gears. Stiffer clutch springs and copper plated steel plates also. That old 1000 was a nice Bike . Never should of sold it.
