There is no accelerator pump on the Mikuni BS36 CV carbs. You will not see any fuel pumping into the carbs when opening the throttle.

Thanks for the info, can't wait to check it out. I've started replacing the washers on the body work with rubbers ones just to help with the vibrations. I have a really annoying vibration coming from the instrument panel but haven't had it off yet to figure it out.

Sorted it,

I've often told people that my main aim with the bike is to bring it up to date, but keep it looking like it's stock. I wanted it to be what Yamaha could have bult, just using parts from newer Yamaha models.

The other thing is that every modification is totally reversible, with basically no work (just unbolt the new and bolt back the old). Each modification has been done without sacrificing the original FJ parts - if at any point I wanted to take the bike back to bone stock, I could do so in a few hours (not that I ever will  ).

I don't have a page on the bike myself, but it's been featured in a couple of articles/magazines where most of the modifications I've made are highlighted/described.

The first one was in Practical Sportsbikes Magazine in 2020 and I've tried to attached the pages of the article here, but failed at the moment (will keep trying) and it was featured in the FJ Journal. The most recent one was the Forever Bikes feature by Bikesure, which you can get to using this link

https://www.bikesure.co.uk/forever-bikes/yamaha-fj1200/

There were little bits that weren't mentioned in the features that I can describe in more detail if you need it (like the LED headlight and other bulbs, the shorter rear suspension dog-bones, the anti-buzz foam washers on the instruments/bodywork etc) and I can provide full details of all of the other modifications if required, but the headline details are in both articles (the mirrors were done after the 2020 article).

Just let me know if you need anything.

Cleaned the carbs and when I reinstalled there was no fuel coming through the carbs. I know the float bowls were filled with fuel but when I twisted the throttle and looked into the intakes (air box not installed) there was no fuel squirting up anywhere from any carb. I'm new to carbs but I would think I should see some fuel squirting up when twisting the throttle. What is the likely cause of this? I'm thinking maybe the floats were not set properly but wondering if anything else could be the culprit before I give it another shot.

I sprayed starting fluid in the intakes and it did fire up briefly but then died because of no fuel.

Quote from: Cruizerdog on November 29, 2024, 11:59:16 PMHi just wanted to ask if the unipods setup has an extra mount for the carbs to support the weight of carbs. Or do the carbs just stay in place from the rubber boots and clamps?

You don't need anything.

The boots hold them fine. We run pods on race cars, all while smashing curbs, getting bumped, wrecking, etc, etc. and have yet to have set of carbs come out of the boots without any support.

Come and visit ya big galoot....you know the drill.

I looked in the carb files and used the search function but didn't see any overviews on how to change the diaphragms on the slides. One of mine is completely ripped so needs replacing. Seems near impossible to get off without breaking the plastic pieces.
