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 ...
