Hey guys

I'm about to take a vacation of a few days to a friends place. He says he has an '84 TRX200 out there. All I know is that it has been bored out. Not sure how much, but they call it "The 250" now. No, I don't know why anyone would bore out a TRX200.

Anyways, they say that now it won't start up. I was going to go out there and take a look at it. What all should I look for? I guess starting at grounding the plug and seeing if I am getting a spark would be a good starting point, also the fuel lines/gas tank.

Just wondering if anyone had any suggestions on what else to look for, etc. before I go out there and see what I can do. I'm still a beginner!

Thanks guys

Motors need three things to start.
Spark, at the correct time.
Compression.
Fresh gas.
If it hasnt been started in awhile, and gas was left in the tank...thats the first thing to change.
Then try getting spark, when it turns over, by holding the spark plug against the head. If you can see it, then its good enough. Assume its at the correct time, if the motor wasnt disassembled since it quit running.
If those check out, then a compression test is next. It should probably have 120 psi or more, for it to start.
Good luck.

 

Thanks for the info.

Won't have a compression tester out there (let alone much of anything). I heard that if it can force your thumb off of the top of teh plug hole then it has strong, or strong enough compression. Sound right?

 

Ya, kind of as a rule. But if you have gas making it to the cylinder, and have spark, itll either be compression or timing.
Its always tough on a freshly put together motor, theres so many things that could be put together wrong. Its a lot easier to get a motor running, that was known to run at one time.
Bring a tow starp, because that may be your easiest way to get it started is to bump start it. Have him put it in 4th, key on, and you pull him, with another wheeler or your truck, and go about 7 to 10 mph, and if its posible for the motor to start, this will do it.
Good luck, and let us know how it goes.

 

tough

what's up with hijacking the post

see what happened to your post?

happened to me, I couldn't figure out why the word tough was a hyperlink

bogus

 

This thread was not Hi-jacked.

Polaris has signed up with ATVConnection.com to have the word "TOUGH" linked to it's site. So, whenever " tough " is typed in the forum. It automatically links. So, there is NO hi-jacking going on.

Looks like hijacking to me!

 

I saw that when i typed it yesterday, then didnt have enough time to figure out what was happening. What other little special words do we have going on?
