Wish me luck
« on: April 03, 2015, 01:01:08 PM »
Long time between posts this is for me. It's been killing me but I've been off the road the last 5 months with bike in pieces in garage. I missed the national Rally, I've missed RTE's, I've missed my daily commute!

What happened was back in October 2014 I decided to finally rid my 94 ST1100 of it's small, but persistent coolant leak.  I'd already had the radiator "fixed" of it's small leak 6 months earlier, but it had returned in the same place.  Fixes are not as good as replacements.

However I also discovered a new leak, the fun one that means removing carbs to check top hoses. So some time around the second week of October 14, I did just that. Removed fuel tank, removed carbs, only to find hoses in very good condition, and no leak up that way.

Bugger.  So the water pump must be it  :-[

I removed radiator, and front engine covers and whilst looking at the timing belt and cam pulley's decided that to proceed, I'll order parts before proceeding.  It was a job I wanted to tackle beginning to end, not wanting to tempt fate with the bikes timing etc.

With great timing Shaun was wrecking his ST, so I was able to procure a new used radiator.  Yippee.  Only problem getting it to me was distance.  I live near Toowoomba, Shaun in Sydney.

My sister in law - SIL (short for Silly) lives in Sydney and she agreed to pick it up and post it to me.  However SIL needed bugging every second day to do so, and about 3 weeks later finally grabbed the radiator off Shaun.

Step one complete.

Now all I needed SIL to do was take 10 minutes to post it to me.  Easy....so I thought.  Unfortunately Brother in Law BIL (short for Billy) had a grander idea, he'll send it through work to save me the $25 in postage (which I was quite willing to pay) and get it up to me straight away. 

What happened though is it sat in the boot of his car for the next 4 months!  Never rely on a SIL'y BIL'y  :p

Meanwhile I had all parts (except radiator) on my workbench waiting installation.  Being such a large job, I held off week to week hoping said radiator would arrive so I could delve into it over one full weekend.  No such luck.

Anyway, fast forward these 4 months, It's now Easter 2015, I have radiator and I'm about to attempt water pump removal, including timing belt.  All of which is a new adventure for me.

What can go wrong  :rofl

Timing belt is fairly easy and I'd never done it before when I did mine. The timing is the critical part so I triple checked mine before I put the covers back on.

Sounds easy   ;-* Timing belt is just a matter of following the instructions step by step, and double checking all the marks when finished. Honda has put so many marks around the place that it just can't go wrong.

Well all went easy, timing belt is a piece of cake, and the water pump wasn't too bad either.

Upon removing water pump I saw what I thought to be the leak, two o-rings in bad shape.  The rest of the pump looked in top nick, the impeller had no corrosion and looked like new. When all was back together the leak is still there, so looks like I have to replace the darn pump now. Hoping a $15 o-ring set would work, but alas no.

I didn't take photos, but did use the following pages as enough to piece together what I needed to do.

Water Pump:
http://www.st-riders.net/index.php?topic=7695.0

Because I had checked the top hoses earlier, putting the carbs back on was fun, particularly trying to remember 5 months later which hose went where  :grin
A tip I used was to heat the rubber boots up with a hair dryer, and put a little engine oil on them so the carbs slipped back in fairly easily. I found use of a piece of timber, and a hammer helped knock them in place.  Not THOR like whacks, but gentle tapping.

Starting the bike up after 5 months idle wasn't easy.  I'd drained the old fuel and charged the battery overnight (It was on a battery tender these 5 months).  Waiting for the fuel to come through did almost flatten the battery, so I hooked her up jump start style to give me the extra amps needed.  Should have seen the grin on my face when she fired up  :beer

This was all late yesterday so unfortunately a ride was out of the question (family commitments). So this morning I suit up and get ready to shake out the cobwebs.

But for some reason I'm way under power, barely able to do 100kmh. I can get it to red-line but there is no "get-up-and-go" on the way.  My pipes sound louder than I remember (I have staintunes) so I have a few things to check. Firstly the choke cable is out. I noticed this when starting this morning, it had little effect, so maybe is wound back too much, and might be influencing the throttle. Just a thought. 

Also the throttle seems ?restriced?  I'll look into that too.

But more likely reason is a carb sync needed. I was extremely careful not to change or touch anything on them but running too much air seems likely. Engine seems to run fine, no misses, just no power. Not having the gear to do a sync might have to rely on the workshop.

However any opinions on this or suggestions would be taken warmly.
