Yes please! Just what I need!

Thanks for all your advice 5twins all sorted now, no leaks after putting in new float pivots. Had to go upto 30 pilots and it ticks over so sweet now I keep thinking its going to die at junctions now, been used to hanging idle, but is perfect and sounds great. So for the record 132.5 mains...

So decided to drill and ream the posts and floats as turning some bushes on the lathe would be too thin. I used two 3mm (1/8") drills as new pivot pins and drilled the posts and floats out to size, i then reemed the float holes to perfect size so that it pivots on the pin instead of the posts...

Well found the issue dont know how i missed this, pretty sure its not meant to have this much play! Click link for video

Cheers 5twins im impressed with your depth of knowledge and cant thank you enough for your advice cheers Hmm ill try that dogbunny as its a no cost option and try lapping the valves as well, they did it with the genuine ones as well which made me think otherwise, ive some small reems so ill...

Forgot to add when one stuck and on sidestand i could hear and audible click shut when i tapped the float bowl Also are the bs38 brass floats all the same found an oem supplier one states 70-80 in the year range? Thanks

Cheers ill do that, the floats stuck pre rebuild with the genuine valves which actually looked and felt alright i think they are cocking over and binding due to wear, now to try and find a decent supplier of floats in the uk, read the bad reports on here of mikes xs ones

Great news ive put 132.5 mains in with 27.5 pilots it now pulls strongly right through the rev range and idles miles better but now and again it will hang, so going to put 30 pilots in now, but i can ride it properly now. Clip is on 2nd from the top as advised. Thanks for all the great advice...

Excellent cheers all done now ready for the jets in the post tomorrow. Thanks for you time and effort with all your advice

Also of note the 4M1 was the needle i took out but have Y55 with the rebuild kit, which would you use? The pilots that came out were 25 without the small holes in the side, and the mains 122.5 just like your table. Ive ordered 27.5 and 30 pilots would you go for the 27.5 or the 30 first, thanks

Brilliant thanks ive gone off that from the carb guide and ordered what you said for mains plus 27.5 and 30 pilots. Also noted the float settings cheers, going to pull whole carbs off and reset the floats instead of just pulling the bowls off for mains and pilots

The supplier link was spot on Martin thanks, range of jets in the post for tomorrow Ill post my results when fitted

Brilliant thats really good advice thanks

Thats great info cheers i dont know what year the carbs are as they are not off the original bike, they have brass floats

Cheers for that, they dont list bs38 parts but just emailed them

Cheers for the advice boots are new and theres no airleaks. Just got to find a uk supplier of jets now or it will be a long wait from us

Cheers for the reply sorry should have stated ive done away with the advance and replaced with boyer kit. Ive non standard filters and exhaust any pointers on pilot and jet sizes? Cheers

Ive just rebuilt my carbs with new keyster kits due to a mixture of hanging idle, and cutting out when pulling to a stop, and sticking floats. However the idle hangs still, cutting out is cured Ive read the excellent carb guide over and over, all circuits are clean and there are no air leaks...

Sorry for the thread revival heres a pic of the finished setup

Haha you recon the video will be in focus with all the vibrations!
