    The bracket has a two bends at the tips and it squeezes through a small hole in the casting. If you look in that area there are little openings.

    Vacuum leak waiting to happen , dremel with carbide bit , a helicoil kit , highly recommend once you have threads fixed ,put anti sieve on the bolts when you reinstall the boot , just in case you have to remove at some point.

    I haven't tried the "home brew" stuff that people are talking about but I am 100% sold on Mouse Milk. It is the best penetrating oil I have ever used.

    I am starting to (again) restore my 1982 XJ650J Maxim. I did it last in 2001. I have a spare set of carbs that I will be refreshing so I can just swap out the rack on my bike with this one. If I can find out how, I can post photos from start to finish. The bike is in the garage and I will be refreshing the carbs in the basement. As always I will be experimenting with a few non-volatile types of cleaners.

    EVOO would be my choice of veggie oil I know some folks that put it on their tools to prevent rust;)

    Yesterday me and my wife went to new hobby shop that just opened , since we were close to Harbor Freight , I had the sale add and with me been looking at the Vicking 4 amp smart charger had it on sale at 34.00$ with my coupon made it 24$ . Got a chance today to try it out , since I have an AGM battery there is a setting for this as well as a COLD setting , already got a couple of battery charger but this one is cool digital read out when I put it on battery read 12 volts showed red 14 minutes later turned green 13.1 volts . My view this is a good charger also comes with the battery post connector , good quality and good price.

    Favorite discovery of the weekend: Self-fusing Silicone tape. Cheap and heat/gas/oil resistant.

    I just wrapped my existing crankcase breather tube with the stuff and threw that back on.

    Rusty bolts?
    Soak in vinegar overnight,or few days, this will remove all the rust.
    After, rinse with clean water, then soak in 2-stroke or fogging oil for a few hrs, seal the bolts.
    Even better, heat the oil a bit, leave overnight.
    Had a quad brought for engine service, apart, all the bolts were a ball of rust in a can, this worked wonders.

    I've use Kroil. A large can will last me a few years. You really don't need much of this stuff to do the job.

    Took the time to pull the carbs and replace the throttle shaft seals. No big deal and the old seals were definitely leaking and old. No issues. I re-synched and color-tuned the carbs and and took it for a spin. Felt great - Hope is helps with starting. I uploaded a picture which was typical of each carb throttle shaft. As a side note I had rebuilt these in February and once off I could re-tighten the float bowl bolts that seem to loosen over time.

    Did the bracket fit the carb? Or did you twist it like that?

    That bracket is a duplicate idle speed screw bracket from a junk set of BS28 carbs. Yes, I twisted/bent it. The screw extender came from ebay with no means of attaching it so I improvised.
    I'm sure it's from a later year Yamaha that had Mikunis. I'm doubtful it was off a FZR750 because they ran Keihin carbs mostly and the carbs were covered by a fake gas tank plenum. Who knows?
    I knew the screw threads were the same so I snagged it for $12.00. I have trouble accessing the idle speed screw in its usual location plus it gets pretty toasty there also.
    Works great for me.
