Hello,
once again i wish to drink at the font of ST1100 knowledge.
Mines a USA 90ish it was first registered in the UK in 90 and they didnt make them much older!! it has 73000 on the clock, timing belt was done a few months ago and the last major job done....
So i had an overheating problem, and thanks to info on here from the great and the wise i shortened the hose from the thermostat to the reservoir tank and that seems to have done the trick beautifully, pending a new hose (on back order 7-10 days.)
I rode from Canary Wharf to Hampton court, a ride of about 21miles, that took about an hour. After crawling through town for 40 minutes, i noticed a slight lack of power when pulling away from idle, then after a further 5-10 minutes the only way to get the bike to go was to run the revs up to 6-7000rpm and feed in the clutch, i hate doing it i feel like i am killing the clutch plates... and i sound like a hoolingan. The alternative was to pull away normally and ride through the misfire, and when the bike hits 4,000rpm the lazy cylinder (i think its just one, it doesnt feel lumpy enough to be a whole bank) finally picks up, the bike surges and rides normally again. Very occasionally, such as pulling away in 2nd after rolling into a red light there is some mild hesitation but then it picks up like normal.
On the ride back, all was normal again, until i hit traffic, then once things warmed up again the misfire was back and on occasion the lack of power quite crippling.
A light misfire was noted in the full service a couple of months ago, and HT leads, coils and plugs were checked with no diagnosis for the misfire.
So my questions are these.
I have Monday off, i need the bike on Tuesday.
After my overheat problem i am going to change the radiator cap and thermostat, i was going to change the coolant hoses, do a flush through of the cooling system, and do oil filter and oil. On further research i find doing all the hoses is going to means lifting out the carbs. I am atempting too much in one day? I wont have access to spares other than comon stuff at motor factors.
Is lifting out the carbs a job for the DIY mechanic? I used to balance the twin carbs on my MGB by ear, i'm guessing thats not the case on a quad setup on a bike. Can i remove the carbs without disturbing the setup?
Lifting out the carbs wasnt in the playbook originally, but it could be the opportunity to find the misfire....
Is there a good guide to the job somewhere online?
Do you have a few ideas of what to look for/at in a day...
and finally, and i'm half expecting a slap for even suggesting it, but i am tempted to pick up one of the fuel addatives you can get in the gas stations here in the uk to see if that helps... I think the commonly available one in STP...
Thanks again for your help, i'm still telling other riders about the you guys spotting the noise a few months back as a failed bearing, and i'm hoping for another more pearls of wisdom...
