Can not re-install carbs on ninja 250r

Hi,

Problem: carbs wont go back into the boots, they are ovaled from when I took them out. I managed to get the carbs into the boots but they didnt slide in. Took it out, cussed, here I am.

Notes:

- Airbox didn't move back an inch, myabe 0.3 inch. I would love more room. Followed this guide. http://www.kawiforums.com/ninja-250r...ll-re-jet.html
- Next try I removed the left engine boot.
- oiled the surface of the boots

Solution:

- tried muscle for 2 hours, nothing. will try again but maybe i can move the airbox more back (that forum said 1" back, but another guy and me only got 0.3")

I'm 100% stuck and frustrated. Any tips? or just keep trying? I don't want to get this far and then have it towed to get it done. This process has been frustrating but will be rewarding when I get the bike running right.

Heights

Thank you.

lubricate the inner lips of the intake and airbox boots. use a couple pieces of sheet metal. One between the carbs and the intake boots, and another between the carbs and the airbox boots.
Slide the carbs into place and remove the sheet metal. While sitting on the bike, push the carbs forward, while wiggling them up and down. they will go in. Then install the airbox boots, starting with the bottoms, then pulling up on the rear of the box to bring the top of the boots into place.

It can be trying but it takes time, patience and practice. Make sure all of your clamps are in place before getting started. Make sure the clamps are round. And make sure the clamps screws are oriented correctly, for tightening. Sometimes the screws are best on top and sometimes they are best on bottom. But they are always best facing out..........LOL.

and be sure to install the throttle cables as soon as you can. before getting started is best but you may have to get the carbs started first.

Good luck, you can do this.

Boots get hard with age. Try heating them with a hair dryer.

That works^^^^
Although I went for the more drastic approach I put some gas on them and set it on fire. The gas will burn off and soften up the boots. NOT RECOMMENDING you try it. I'm just saying the heating of the boot works

I'd recommend the hair dryer honestly.

Also lube the carb side as well.

on more thing.. on my 90 GSXR, I would put a 2x4 across the big side of the carbs and use a pry bar of some sort to pop them in there. On the gsxr there was a cross bar that ran parallel with the carbs so it worked great.

Thanks to FZ1, we got them in. Lube and wood stick and friendship did the trick. (always does)

Thanks all for advise, we have another issue but one thing at a time.

Umm... Just to be clear the lube was for the carb boots, the wooden stick was to help pry them on and the friendship comes natural to those who meet me in person lol. Oh and the other issue is that 1 carb had no vacuum but we ran out of time and will get them synced tomorrow. Just to be clear lol
