got a couple of questions

[rbrown620]

Well, I was recently given a non-running 2001 gz250. Cleaned carb and fired right up. Drove around and noticed some popping noises from chain. I'm assuming this means it needs to be changed. Its adjusted all the way out so were is the cheapest place to get a new one and should i get sprockets with it? And what it the 16t sprocket change? Does it require a different chain? Thanks for any help.

From your description I would go for a new chain and at least a new front sprocket. Sounds like the chain is trying to climb over the front sprocket teeth which will definitely be damaging them. The rear sprocket may not be too bad but in my opinion chain and both sprockets is the way to go. At least you will know what you have and need only lube and clean the chain.

Welcome.Chains and sprockets should be changed at the same time.Changing to a 16t sprocket does not require a different chain.Chain size is a #520-110 link.The 16t sprocket gives you lower revs at road speed.probably cheaper to buy chain & sprockets on e-bay.

thanks for the info. guys. i need to get a front tire, chain and sprockets, and turn signal bulb. For free who can ask for a better deal right.

What's the mileage? :)

[rbrown620]

8900 miles. Motor was seized because it had set for 2 years but sprayed wd-40 and let it set for 3 days. Cleaned carb and fired right up. Not smoking or anything.(YET) :2tup: Does anyone know what front turn signal bulb this bike takes (1157)?

[blaine]

It takes a 21-5w bulb.Must be right wattage or signal lights will flash erratically.

I would inspect the sprockets first, to see if they actually need to be changed. There's a chart in the owners manual that shows you exactly what is good and what is bad.
However, your description of the noise the chain is making leans toward frozen links and probably should be changed.
Good luck and great price for the bike.

I don't really understand :??: What exactly did you spray? :)

[rbrown620]

I put Wd-40 into the cyclinder through the spark plug hole.

Prob took the spark plug out and shot it into the cylinder.

Mine too.

This is the time to do the 16T upgrade.....for free, effectively.
It should work OK with the stock length chain.....since there is only one tooth difference.

If it is out of adjustment and still making snapping noises......it could be worn so bad as to potentially be dangerous; don't put off this fix and continue riding it.

Motor was seized ......

Given that, it would be an excellent idea to get some MMO (Marvel Mystery Oil) and put a recommended dose of that in the first few tankfuls.....just to give the rings a little extra lubrication to finish the treatment that you started.

If there are signs of excess oil useage later, you might want to repeat your initial treatment, substituting MMO for the WD40.
