RE: HELP = I cranked the motor and dropped an insulator nut down the intake side - HELP
Your not the first person who has done something like this. Not by a long shot. I've seen it before, in fact my GT was put into storage prematurely by it's original owner who dropped a bolt into the intake then started it. It actually started then a piston shattered a couple of seconds later. He lost all his MOJO and parked the bike under the house for 30 yrs to be rediscovered and restored by me.
Dont be put off by the fucktards in here bagging you out, it's very easy to do just what you did. Good on you guys, for giving him the worst case scenario and offering to take his money. Thats a great way to help.
You wanted a project bike? Well now you have one! Dont be scared of it. While tipping your engine/bike upside down may seem crazy to you, i''ve seen some pretty crazy shit turned upside down and shaken to recover tools or parts. It may get your part back, but it wont fix your problem. Dont do it. Because you may have more things to fix, so you will have to open it up anyways.
First thing you need to do is establish if it is actually a foreign object in a cylinder causing your problem. You would feel pretty stupid pulling the head off only to find your trying to turn the bike over in gear or something know what i mean? Remove all your plugs to relieve compression, remove your carbies again for access, and even remove your exhaust headers for access if your sure there is something in the engine. You'll want to take the radiator off as well i reckon. Take off as much as you need to then turn the engine over carefully with a socket on the crank to feel for the binding and listen carefully to determine if it is actually what you think it is.
Once your sure thats what it is, off with the head. Firstly to get your part back and secondly to inspect it for damage. Follow the workshop manual, take your time, and buy tools if/as you need them. You may find a bit of damage that may need repair, you may find some that wont. You need to lift the head to be sure. At any rate, the damage will only be restricted to one cylinder. You may need to replace a valve, you may even need to replace a piston. All of this is replaceable yourself, without paying someone thousands of dollars. You will be surprised how much it WONT cost if you do it yourself.
This is the sort of thing i found, mind you this sort of problem with a two stroke cause a bit more damage.
I think your problem will quite probably be restricted to a valve and a seat. With negligible damage to a piston.
Im keen to see what you find, post up pictures and start a project thread, some of us will be happy to guide you through it if you need it. Others are just going to laugh at you. But you will have the last laugh when you have fixed it yourself and know your bike from the inside out!
