I have a fl400 I am trying to get going. came with burnt piston. prev. owner put a aftermarket pipe, new reed cage and reeds and a 38mm mikuni flat slide carb. I am trying to go to the sand in 2 weeks so timing is important.

I have the original carb as well. it is missing the choke

I have got it running with the Mikuni. just two brief fires. but can not get the stock air boot to go on the carb. I have tried heating and pressing and just do not see how I could trust it not to come off if I am able to get it on as well as having to jet it. so on and off many times.

is there a aftermarket boot?

where might I buy a stock manual pull off choke? I have the original choke and throttle cable but neither end.

ideally would like to make Mikuni work but with a choke I think I can go with the stock and ride it in two weeks. then work the boot.

previous owner burnt the piston on his first trip, but did not know why. he said he put the float in upsde down. can not see how that could happen. He is old and memory is of question.


any help would be appreciated.

Hello, i am not a pilot guy, and really cant answer your question, how ever, repost this in the tech section. i believe someone will see it there and be able to answer

I havent tried putting the boot on yet with aftermarket carb,but I thought most people were having the problem with the flange more than the boot,that's why dmoney was getting these made

I think Mudbogger found a replacement choke kit the Pilots but I forget the details anybody else remember?

I am still looking for a solution, if anybody can help.

the air inlet side is 61mm on my 38mm Mikoni. stock would appear to be 55mm

Do you have the stock cable? I also replied back to your PM SIR!

Also THE STOCK CARB AND BOOT SHOULD fit together with ease, a picture would really help , try to heat the air box tube in warm to boiling water, that will be the best way to fit it over the carb itself, works wonders, but again that boot must be wrong, something does not add up it should fit with a touch of resistance, if it is that small on the air box side I am thinking something is off, the carb is stock right? Or is it aftermarket?

thank you for the link. yes i have the cable. the stock boot does not fit on the Mikuni. fits fine on the stock carb. I prefer stock and I know how my other one is jetted, so that should be fairly simple.
Thanks
