what is it now, still not working right

[stock-ish]

I just rebulit this sill thing (had cases spilt for trans issue) So I put rings in it.

 

I put it together took it to pismo and overheating. had 310 main with needle clip in the middle--pulled carbs put needle at full rich, better still not right

 

Bumped to 320 mains and put needle in one lean fron full rich. Took back to pismo with some engine ice. (inspected h20 pump and rad all seemed ok)

 

Ran great, it is the back up bike so I had my girl riding it. It was her first time salot of lugging and reving. She was going slow I would check it out temp wise, ok.

 

Here is the problem after the first day I jumped on it and it had lost all of the low end. Like it was stuck in 2 or 3rd gear. I would have to rap it up to the moon then dump clutch. Plug still looks good. ANd rips once you get the R's up, very fast

 

Should I go higher on the jet? anyone know? I am about ready to give up anyone know of a place in San Jose that is good I could take it too. This thing is kicking my ass.

 

This is the first 2 stroke I have ever mess with so I am a little confused

oh it a 97 if that matters

and had aftermarket sator with adjustable timing. It is set at zero. maybe it should be retarded?

 

Also found it is missing a spring holding one of the headered on and the couplers from headpipe to muffler pipe are leaking ex. Not bad but some.

Did you hone the cylinders before putting it back together? Possibly the rings didn't take a seat. I suggest checking your compression.

That's your best bet. The other thing I was thinking was a air leak. Check those crappy stock intake boots real good. I had the same problem and sure enough there was a small slit. Good luck.

def check that compression!!!

thanks for the hlep. It does sound like lack of compression or piston issue. I didn't do the break in on the rings my buddy( the owner) did it (it just lives at my house and so I get to use it when it is running that is). I told him what to do but I justgot the sand rail finished and wanted to drive it.

 

Do you think if he overheated it (several times) and beat on it the rings never got a chance to seat or beak in? ANd that could be the problem? I did hone the cyl wall with a stone hone and cleaned the out well.

 

I will check compression. If it is low how do I check if the pistons are good? Did I mic them like a 4 stroke bike?

 

thanks

I know it has been a while but busy at work. Checked the compression and was about 100 to 110 in that range. I did a wet compression test and it was 120.

 

What is the comp spec? Am I looking at collapsed rings or possible reed failure?

 

thanks
