Sportsman 800 silencer questions

Need some help here guys. I have an 05 Sportsman 800 and the RH silencer broke at the cross-over tube. Where is the best place to get one of these? Is there some aftermarket companies that make these?
Also, can I change the exhaust from dual silencers to a single silencer? IF so, what would it entail.

Sorry for the dumb questions but this is my first ATV purchase and I’m learning as I go with it.

Thanks,

Bought a Not-Running Trail Boss 250, any ideas?

Saturday evening I came across what appeared to be a good deal for a 1998 Trail Boss 250. The previous owner has had it since the showroom floor. It ran great for him from that point up until last fall. A family member was riding it down the trail and it up and died on her. Has not been able to get it to fire since. They replaced the top end, still could not get it to start. They threw it up on the local classifieds for $300. I was the first to respond, and now its mine.

Knowing the top end had been rebuilt, I brought it home thinking that it was something electrical, or fuel related. Got it home and immediately began to tear it apart. Pulled the plug out, ground it to the motor, and pulled the rope. Got spark.

Put my thumb over the spark plug hole, and turned the engine over, blowing my thumb off the spark plug hole. Appears to have enough compression to start.

Moved on to the gas tank and carb. The tank was all but empty, and the carb looked like it needed some TLC. Pulled it off, cleaned the main and pilot jets, cleaned the slide, the throat, and put it all back together. Drained the rest of the tank, cleaned it out and put fresh premium in it. Put it back together, pulled and pulled and pulled. Nothing. Hooked it up to my car to allow the starter do the work. Still nothing.

Checked the throttle cable for proper adjustment, unplugged the ETC, nothing. Key switch, and kill switch seem to work as normal.

After several minutes of holding the throttle wide open, full choke, half choke, feathering the throttle etc. I was at a loss. Pulled out the spark plug and poured a small amount of premix into the cylinder. Still nothing.

I decided to pull the pull rope for a while, one of those pulls, the engine stopped like it was seized. After a little persuasion, it finally turned freely again. It only took maybe a 1/4-1/2 rotation for it to spin freely again. I do not believe the engine to be seized because it now turns freely again.

I know this is a lot of info, but any ideas? Is it possible that a skirt or a ring is down in the bottom end banging around in there? Would that keep it from starting though? FullSizeRender (17).jpg ,

Need manual and assistance

I have a 91 Trail Boss 250. I am rebuilding the motor on it and I need the manual for torques for reassembly. I pulled the crankcase apart and need to know what type of sealant to use when putting it back together. First I need a pointer on how to get the crank case apart. I need to replace the crank shaft seals and bearings. I do not know when and if it has ever been done on this atv before and the guy i bought it off of seemed less than knowledgeable on the fourwheeler. Any help would be appreciated. I feel dumb cause I can repair and rebuild a turbine engine in two hours for my helicopter but this little two stroke is kicking my @$$.

Front Brake Master Cylinder Rebuild?

Hey guys…

Looking for some help to do with the front brake…I went riding a while back and during the middle of the ride I noticed that the clear (peep sight) on the front brake was "loose". It was actually completely sticking up and I had to grab it or it would have fell to the ground.

I have tried to put it back together but it still looses its grip or suction and pops right out when you squeeze the front brake. It still has brake fluid in the reservoir. I guess im trying to see if I need to buy a new lid, rubber gasket and peep sight or if I should just try bleeding the front brakes to see if the air in the reservoir is causing the problem. I guess my thinking is that maybe the pressure/suction sucks the peep sight into place???

Any help would be appreciated!

Help Ranger ducting missing!!

Hey guys

I have a 07 Ranger and the original owner removed the original air intake and cooling ducting and installed a homemade snorkel system. I would like to reinstall the original equipment as the engine and clutch noise is really annoying right behind my head. I bought a intake duct from a 08 off of Ebay but it doesn’t seem like its right for this year. Does anyone have a proper listing for what I need? and how it is routed through the machine.

Thanks
Scott
