Raptor 700 help I'm stumped
Ok so I tore my raptor completely down because I broke some gears in the transmission I got all that replaced and also decided to get a high comp piston and a wiseco fuel controller and finally got it together and then when it finally decided to fire up I broke my timing chain and broke the decompression assembly spring so I bought a new chain and the whole decompression assembly and again got everything altogether again and this time it fired right up but about 5 seconds of running I got a loud squealing noise so I shut it off and I have no idea if it was my clutch but I had slack in the cable and tightend it and it was gone next time I started it and I let it sit and idle for a while and shutting it off and checking fluids and I decided to take a spin on it and it died on me and I heard a pretty loud winding noise from what sounded from the motor and since I cannot get this thing to fire at all I've checked spark I'm getting fuel i just don't know..although when trying to turn it over the starter sounds different than normal and seems to be turning the motor over a little faster maybe then again I may be dillusional idk does anyone have any ideas ??

We'll that was my next plan but I don't have a compression tester at the moment...I know it's obviously not accurate but I stuck my finger down the spark plug hole and turned it over and it pulled my finger in pretty good and I would think it would at least try to fire up but it's not at all I mean even if it had low compression wouldn't it still try to fire up?

Well it needs spark at the right time, fuel, and compression to run, so you're missing one of the 4. You say you have fuel and spark, so that leaves timing and compression. With all of the engine noises that you had, I'm worried about the compression. If it's way low on compression, it will not run.

Ok so I checked valve clearance again I adjusted intake and exhaust like a hair and now I'm at 115 compression timing is dead on spark plug still getting a nice blue spark off the head it acts like I'm not getting spark when the plug is in ?? Ahh I'm going insane I've never had this problem
