I seen on one of the post do not use red lock tight. Well I did last year how hard will it be to get the bolts out with out snapping then? if so can I heat them up.
 

heat will deffently be your friend.just heat the area on the cyl where the threads are with a propane torch,don't need alot of heat either the loctite softens at like 200 degrees c .to much heat could cause you worst problems.honestly the only place i use loctite (blue) on these engines is stator and pickup coil screws , flywheel nut and engine mount bolts. 2 srx's and 50*** km's combined and i have never had engine bolts fall out. the suspension and chasis bolts are a different story they all need loctite.

OK I'll try some heat. But what problems are you talking about so I know what to look for.
 
The first thing you should do is take your bottle of red loctite and put it in the trash. Red Loctitie is for installing parts PERMANENTLY. You only need BLUE LOCTITE for servicing your sled. The next thing to do is to get a copy of the service manual for your sled. It shows exactly which fasteners need Loctite. If in doubt, always post a question on this forum and you will get a speedy answer.

CAREFULLY apply heat to the cylinder, in the region where the stuck bolt is threaded into it. Aluminum is an excellent conductor of heat so the heat will spread quickly into the region where you need the heat. For removing bolts which are stuck due to corrosion, I heat the fastener, quench it with penetrating oil and reapeat for a few cycles. After a few cycles of this, apply heat one more time the CAREFULLY turn the allen wrench to start moving the bolt. Hopefully you will remove all the stuck bolts without breaking them. Aluminum melts at 660 degrees C so goes EASY with the heat. Have a fire extinguisher handy, just in case.

When you reinstall the bolts, put a small amount of antisieze on them. They will NOT loosen up and fall out withthe antisieze BUT they will be easy to remove next time.
 
I found the theadlock its made by permatex (high strength),It comes in a blue tube.Boy I need to read the tube next time! So going out to shop to have some fun. Thanks for all the info
 
Try useing a brazing tip on a torch with a small sharp flame, heat up the middle of the bolt head a few times takeing your time so the heat will work its way to the end of the bolt.
 
Thanks to everyone who replied. I was able to remove all the bolts, with pb blaster and heat.......PATIENCE WAS MY FRIEND!
 
Excellent, I am glad it worked out for you. Put the bolts back in with a dab of antisieze and you won'y have any troulbles removingthem in the future. Clean and adjust your power valves and if you have not yete cleaned the carbs, give them a good thorough cleaning.

If you need any help, post your questions. The folks on this site love to help each other.
