ST 11OO Overheating, Cant Change Gears

[ulti682]

   Hi all, i have an issue with my st 1100, just bought it, it had been sitting in a shed for 2 years, all fluids checked and ok, but when it got going and the bike got warm to hot sitting in traffic waiting for road works i couldn't select gears untill it cooled down, also it seems as if the clutch is riding.....any thoughts would be appreciated thanks. Bike has done 122,000 has a tow bar but doesn't look like it's even had a ball on it.

that is a new one to me, I have never heard of that but many of the brains trust here know a thing or two

After 2 years of sitting:-

Maintenance Schedule:- as per Haynes Service Manual, page 1.3

Every 12,800km or 12 months:-
Engine oil and oil filter  (see oil section on forum)

Every 19,200km or 2 years change the following:-
Brake fluid
Clutch fluid
Coolant mixture

The manual says there are other items to be serviced as well, but this is just a snap shot.

I would do the above and then test ride.  My 1100 gets hot just sitting in traffic, but once moving, the gauge reads normal. Otherwise check thermostat.

Others will chime in soon, that's my 2 cents worth.

Good luck and lets us know how you get on.

Have you changed the brake and clutch fluid, that could cause the clutch to not work so well with elevated temps. Also has the engine oil been changed, and if so what did you put in.

The temp will go up, when stalled in traffic or idling along. Temp should only go to about 2/3 to 3/4 then the fan should kick in. If that is working and the temp drops as you move off, then dont worry about that side.

In addition to undertaking what Brock has already advised you could also remove, clean, lubricate and replace the gear linkage that connects the lever to the gear selector 'drum'(for want of a better word).

This is quite often over looked with regards to routine maintenance as it does collect a lot of moisture and road grime. If that fails to rectify the difficulty in engauging a low gear when stationary, you may well need to replace the selector drum itself. The ST's selector is inherently 'notchy' to begin with and not helped when hot and old oil.

Reason...IF, because of recurrent forced lower gear selection due to un-lubricated and 'sticking' linkage that hasn't been maintained OR if the bike is overloaded (as with a trailer, for which it was never designed), then often the excess weight (exacerbated further if 2-up), on an uneven road surface adds weight to the drive train that requires the rider to actually 'boot' the bike into 1st gear. Rather than easing it into gear with a steady downward pressure. The selector components burr over and wear beyond repair.

The good news is they are not to difficult to replace.

As for your clutch, l have another thread elesewhere on this site with pics when l changed over a clutch basket that had burred badly and l used the same plates and removed the non OEM anti shudder rings.

Cheers the can:-)

Thank's guy's, great help, my friend rode it back from Melbourne so we will do a service and change all fluids, i did read somewhere that using diesel oil in the st 1100 helps, not sure on that one. Also i only rode it for the first time last night, the clutch lever is very strong, and you cant select g1st gear from nuteral unless its all the way in hard against the bar, even then it goes in with a slight grind and jump, and wont take off till the lever is nearly all the way out  seems strange.......

That indicates, that the clutch isnt disengaging completely. Definitely time to replace the fluid.

Diesel oil works well, I am using Penrite HPR Diesel 20W-60 extra 10 full Zinc mineral oil.   Filter is a Repco ROF 135.;
