Had planned to do two things this Sunday afternoon.
Work on the SF2 and go fetch the track bike to bring it to a place where I can work on it.
All my bikes, parts and some tools are in a place known only to myself so as to keep the stuff away from the clutches of my future ex, her lawyers and bayliffs. Unfortunately, long time storage is not being kind to all that stuff but then I have something to look forwards to when I retire and divorce proceedings nearer conclusion.
I didn't have time to go and fetch the track machine, spent the afternoon on the SF2.
Right hand crank oil seal needed changing. Having the correct tools, in about 10 minutes, cover, dynamo belt and starter freewheel were off and the old seal prised out. It was in fact leaking from between the seal and crankcase. Inspection showed that there was a burr in the case due to a hamfisted owner (myself) probably using the end of a large screwdriver to tap a seal in. A bit of wet and dry soon sorted that.
First attempt at getting the new seal in buggered it. Luckily, I have some spare. I found a large, near 80mm drift to help push the new seal in. That worked but the seal isn't flush with the edge of it's housing. It's a very tight fit, I needed once the seal was in, to cut off some of its rubber shaved off by the housing whilst taping it in. Shouldn't be a problem, we'll see on the ride in to work tomorrow morning.
Then looked into why the engine "fluffs' on pickup in town. Points were clean. Took both carbs out. A bit of fine rust in the left hand float bowl. I'd had the tank painted, was it two years back, and a dent pulled from the tank needed it to be rinsed out with soapy water so as to weld a nail to pull the dent, hence the rust.
That dent was pre divorce, things were going really badly and I'd ridden into town and then ridden back, totally pissed to the point I'd dropped the bike, twice, whilst putting it on the center stand in the garage.
So, cleaned out a bit of rust, blew into various jets and passages and checked the float heights. The carbs are new from last winter and have the white floats with a bad reputation. I'd used a tankfull of euro 95 octane with 10% alcohol last weekend and was worried that the floats had suffered. No problem.
I changed the rubber gaiters on the end of choke and throttle cables since they were cooked.
Found nothing particular.
I then polished the bike up.
We'll see on the ride into work tomorrow morning if the fluffing is still there. If so, I might try 65 pilots in lieu of the standard 60s in there at the moment. I very much doubt that there's a problem there.
May try BP8 plugs. Used them once. Much cleaner running in town.
We'll see.
Paul
