Ok so just picked up an 02 ds 650 and the guy said he couldn't get it to start. He had a shop put new shims in it and I had them checked and they were ok now things I've done is new plugs even though guy had just put new plugs in it.. got new carb 42mm just like the one that was on it.. bought new intake manifold because the one that was on it someone got way to tweaked out and ported the shit out of it excuse my language but yeah so installed new intake manifold and it just won't start like its not getting enough fuel. Timing seems to be right it does fire every now and again but just barely.. did a compression test today and it was at 90psi.. i know thats low but don't know where I'm losing compression.. valves we at .06 and .07 when checked im lost ive tried everything I know and can't figure it out
I started this project a while ago.. I have decided to make one thread I can continuously update..
So , here we go. I got this Raptor 80 in really bad condition.. Rear end frozen, Engine toast, tires dry rotted, tons of rust..etc.. They admitted they beat on it very hard.
Since they do not make these with a drive shaft anymore I decided to restore it from top to bottom..
These are photos of when I got it home.
Next up, the tear down..
First, I needed to tear it down and determine if the rear end was still good... As we all know... That is where it would be cost prohibitive to restore if it is trashed..
Got it completely stripped down and I lucked out... The rear Drum brake was caked solid inside with dried mud. That was causing the rear end to lock up. Took off the rear brakes and the rear end spun perfectly smooth.
Once I got it all stripped apart I needed to take the finish off all the parts. I am going to be powder coating the frame and many parts.. Once the finish is off each part it will need to be sandblasted to white metal .. The guy I use for powder coating gives me a hefty discount if I bring the parts to him ready to go.
You could just sand blast, but that would take a long time to get the finish off. First I used Aircraft Paint Remover.. That stuff is pretty toxic Goggles and Resperator are required. That quickly gets you down to the metal... Then you can sand blast to white metal pretty quickly...
I had another thread I had started about a problem with the tear down... It has some great info .... here is the link... It is about removing the frame bushings. ....
