Inlet rubber3bn/3et

Checked on csm l, part nos for 88 and 89 bikes differ, as does the joint between the air box and carb, no extra bottle and yet to see one? Can you post pics of it?
Resized photos but still could not upload, said I did not have permission? New post uploaded at second attempt? Not worried, got there in the end, thanks Calum -
Cmon boys... you should know this,
88 3BN' inlet is for the VM26ss Mikuni, that was what the DT125R came out with,
Later updated to 3ET, a 200R code, using the TM28ss Mikuni flatslide.
The second YIES bottle towards the airbox wasn't introduced until 1999'

@darty that would explain it, I think mine had the flat side retro fitted and would have had the earlier carb to start with. Rubber joint to Air box later one and just the crankcase joint wrong one. Have the 3et from the 89 bike so I am going to fit that for now and reorder, thanks for the advice, now you have pointed it out it's clear. Appreciated, consider me told!

All fitted,just as well, UPS never turned up with the new one from csm l, then sent email saying I was not in when delivery attempted at 4.59. Bulls##t! I was working on bike right by front door! Long story short coming Saturday after phone argument, driver tried to deliver to no 5, I live at no 9. Every fk'd up delivery I get is UPS, even their app is garbage. Bike starts and runs fine, a lot easier to fit carb as well with the correct inlet.

@oldman Power Jets are awesome.
Basically when the bike is at a decent load but not accelerating, it soesn't need to use all of the main jet as that is too much fuel, the power jet instead takes over which uses slightly less fuel and has a leaner mixture.
They are not there on all carbs.

@ricky0115 It should be a paper type, quite common for these to let air in here when botched.

@ricky0115 Use Athena, or OEM gaskets only.
You can get some paper gasket adhesive to just ensure it's properly sealed. It's what I've used on my engines.
