Guess I should say my new bike. I recently purchased a 1993 ST1100 that has been sitting for 3 years. The previous owner kept good records of the bike and was having the timing belt changes as a prevenative measure. After the timing belt was changed he drove the bike about 2 blocks from the shop before turning back around due to a noise from the engine. He described it to me as a whine. The same shop changed out the idler pullys and started to reassemble before they went out of buisness. the p.o. trailered the bike home and let is sit for about 18 months before taking it to another shop to repair a leaking fork seal and also have the carbs cleaned and timing checked. the shop cleaned the carbs and repaired the fork seal for him and apparantly told him that he had either a stuck or bent valve. again the p.o. stopped work and towed it home where is sat for another 18 months before i purchased it. I have so far got the by to run by installing a new battery and some premium gas. also added seafoam to the fuel to assist in clearing the carbs. I plan to run a compression test today and verify that there are no bent valves. I honestly believe the shop who cleaned the carbs did not properly adjust them and it is causing the running issues. any reccomendations are greatly appreciated and I will report back after i run the compression test today. thanks fellas. If anyone has the base idle jet settings or the adjustment procedures I would love to have them, just to verify shops adjustment. thanks again.

s, i know i am now posting in the wrong area, but my carbs are still a concern, just not as much of one now. I dont have a service manual yet, but are these marks lined up on the wrong crank position?

Sorry to hear about the demise of the STeed. I have a couple different service manuals that I need to sell; a Clymer and a Haynes. Let me know if you are interested in either.

I posted in your other thread, but will reiterate here; the 1100 engines are mostly the same. I would suggest that you locate a 96 or newer one, with the alternator, just to get the bigger alternator.

There are a few engines on sale on ebay; biggest issue would be shipping.

actually i think the previous owner updated to the new style alternator. i know that he said the rectifier was no longer needed with new new alternator. will any st1100 engine work, or is there a year range that is interchangeable?

If you already have the 40amp, then you can just get any year engine and swap. Don't worry if the replacement has a 28amp or any alt at all. If you find an engine with a 40amp, you could sell the alt and extra bits for a nice chunk of change.
