1986 Lt 250 acting up

[quadzilla4]

I have a 1986 Lt 250 that I just picked up for $900.00. However when I took it out today it was acting ok but then when I raced with my brothers quadzilla it started acting up. When I shift into 5th gear the bike bogs out when I hit the throttle. Then I let the bike sit and when I started to ride it again I shift it to 2nd gear and it was hesitating it wanted to bogg out. The bike would go then like die down then go again then die down till it turned off. The bike had gas and choke was off. Whats wrong can someone help me.

could be a couple of things, maybe a clogged jet i would clean the carb. check if your getting good fuel flow to the carb, sounds like its not getting gas or the spark might be cutting out.

I had a similar problem with my 85 few weeks ago. It would run fine and do exactly what yours did. Well my 5 year old son figured it out. The gas cap wasnt breathing right it was vapor locking. I had pulled the fuel line and nothing came out and when he took the cap loose she flowed. So I started banging the cap around and rust came out where the hose was on the top. If that aint the problem then you need to dissasemble the carb and clean it up.

My brother had the same problem with his Lt 500 put I just purchased a new gas cap and it fixed the problem. I checked it on my Lt 250 put still have same problem so any other suggestions I havent cleaned the carb yet.

Goto the parts store buy a can or 2 of carb cleaner aeresol spray. Grab you some newspaper lay it out on a table. Remove your carb and clean and dissasemble. If your unsure where the parts go grab a digital cam and take some photos. I usually just lay everything out in the order I take it apart but I repair automobiles for a living and it comes easy for me. What kind of carb does it have on it a mikuni or other?

[quadzilla4]

It has a mikuni so cleaning the carb will fix my problem. By the way do u know a place were I can get a chrome pipe and other parts for a reasonable price or so.

mikuni is stock carb, I would clean it and if that dont help buy a kit from someone rjatv might have one not for sure. check with rjatv he might have or know where to get some reasonable parts. I bought some stuff off of him off ebay before excellent to buy from my 2 cents.
