Self Inflicted Wounds
« on: 24 June 2013, 05:31:34 pm »
After a weekend of Ivanising you'd think I'd have spent enough time recently with carbs on the bench, wouldn't you?  Well, I managed to shoot meself in the foot twice this weekend ...

First, a couple of weeks back I had the R1 carbs apart to unbung some blocked pilot jets.  Not ridden enough, 'nuff said.  While I was at it, I fitted new float bowl gaskets.  Held them in place in the bowl covers with a couple of small dabs of sticky silicon grease.  All great so far.

Saturday I fitted the R1 radial master cylinder to the Fazer.  Just needed to do the final bleed on Sunday ... no probs, do it after a ride on the R1.

The first 150 miles were brilliant - love that R1 motor - then suddenly I'm on a 750 3-cylinder.  Don't think I'd buy a triple if that's what they feel like ... but anyway, it ran on 4 below 3k rpm and on a whiff of throttle, so nursed it home and set about clearing the workspace.  Just bleed those Fazer brakes and move it out the way - oh, bollox!  R1 master cylinder must be good because it's blown one of the caliper seals!  :(

So, off with the calipers and out with the seals.  Then shuffle over to the R1 and pull the carbs on that one.  First float bowl I opened up revealed a blocked main jet.  What's this?  Looks like some kind of gel ... ah!!  Guess who's just learned that HT silicon grease doesn't dissolve in petrol.  A small glob must have been squeezed into the float bowl where it took its time finding a home in the main jet.  Problem solved. :)

As for the caliper seals, what's with Yamaha parts pricing these days?  Fowlers quoted me just under £130 for 16 bloody rubber rings!   At least Dick Turpin wore a mask!  :rollin

Although it goes against the grain, I'm trying pattern seals at £37 for the full set from Wemoto.  Claimed to be OE standard and I'll take a chance on that, since I figure Yamaha don't make their own anyway but buy them in and slap them in Yamaha packaging.

Wish me luck ... :)

  • Had the same thing a few years ago that you might remember, a tiny bit of rubber glove stuck in the main jet...
  • And yeah its like they are maliciously trying not to sell spares..

Yup, I recall that now you mention it.  Wish it had occurred to me straight off the bat yesterday, 'cos I was thinking of all sorts of other possibilities before common sense reminded me that the thing you worked on last has to be the most logical place to start. :)

Who says I'm not a quick learner ... ? :lol
