i need help its me again sorry for the trouble but i have a fzr250 1990 model and this afternoon i tried turning it on but wouldn't turn on and it wasted my battery soo i charged it and turned the bike on again but still wouldn't turn on there its not a electrical problem because you can hear it is it the sparks or the carbs

OK. It crank, but it don't start. 2 things may happen: 1st, your spark plugs don't give spark, 2nd carbs don't give fuel into the cylinders (and that might be cause they don't have fuel). First things first: take one of the plugs off, have it into its pipe and attach it on a metallic place on the bike. Push the START button and look if it sparks. If it does, then i don't think you have a spark plug problem. If it doesn't, change it.

If sparks are OK, and all of them ignite, try to see if your carbs have fuel. Each floater of them, have a cross-screw an bottom. Unscrwe it and look if fuel drops out. If yes, you don't have to search for glogged fuel line or damagged fuel pump. The problem should be into the carbs themself. They'll probably need a good cleaning.

First check the spark plugs and then the fuel line. Good luck.

shears just one more thing why is my battery overcharging making the bike run out of power

Over charging battery means your Voltage Regulator (VR) is bad, change it.

thanks for your help guys and now its going to cost me $80 for the regulator

I wonder if the R6 or YZF regulator will work on the FZR250

As far as i saw untill today, all fzrs (250-400-600-750-1000) share the same VR. Many guys, here on fzronline.com, swaped their VR from R6 and YZFs. Thus... why not? At least i would do that.

iam going to do a major service on my fzr250 1990 model because i know the old owner lied about servicing are all the sparks the same or they try to make money out of you because of the brand and for the oil whats the best and oil filter,air filter.what else is there did i forget any thing i changed the battery 2 weeks ago is there any thing i can change to make it go harder

Doing the major servece, is a very good idea. There on, you'll know WHAT and WHEN. My opinion, is to put a good quality synthetic engine oil. Good air and oil filters and it'll be great! Change all 4 spark plugs (as you're misdoubt about it), clean the carbs and that's all. That's what i always doy when i take a new bike. Previous owner might claim "perfect condition", but... ha, that's what they always say.

Do nothing to make it go harder. A 250 will always be a 250. You can't do much for more power on it. Except, if you want to keep it for ever, and you don't care about the money you'll pay. That 250 ('90) had a hell of an engine on.

Exup valve it's something that rarely (not to say never) needs cleaning. If you want to clean it though, take it off and use a scrub brush. For cleaning the exup valve seat, use a carburator cleaning spray. They do a lot of work

realy imprecate it csofos thanks alot
