Problems after rebuild

[yztrailBLAZR]

so i did my first ever rebuild and i thought it went pretty well... until I tried to start my bike again.

It has alot more compression, but it wont idle without the choke.

When i went to ride it, it looses power after I finish warming it up. I go into first gear and then it wont respond to my throttle and becomes very quiet and it wont give me any power.

I rode it one time before after the rebuild but it had very little power then too and it randomly lost power too.

I'm hoping its just a carb problem or something.

I didnt check the end gap either when i rebuilt but i used a wiseco rebuild kit so i didnt think i had to.

Sounds like a fuel delivery issue to me as long as everything was re installed correctly and the right parts were used... but theres no rag stuck in the air box is there? Common mistake and Ive made it a few times as well.

If not sounds like you need to pull the carb.

A rebuild of what if you don't mind me asking? Just the top-end or also the bottom end?

top end.... theres also oil dripping out of the little tube that comes out of the cylinder head.

I cleaned that part out when i rebuilt. I believe there could also be gummed up gas but I dont want to take it apart :/

i would check your base gasket or check your reed cage but im guessing base gasket

Did you torque everything down correctly? Did you reattach the powervalve rod? What jetting are you running?

[FGR01]

What jetting? Heck I'd like to hear what year/make/model bike it is first!

if the powervalve rod is the thing to empty the antifreeze, then yes i did.

i dont know the jetting but it was working fine on 32:1 before I rebuilt now its doing this on 32:1

its also taking many kicks to start.

Did you re-attach the power valve rod correctly? You have to have it aligned correctly before you tighten it. Check service manual.

Did you make sure the arrow was pointing forward on the piston. Not trying to insult it has happened I don't know if it would run at all.

no wiesco points toward the exhaust.

no wiesco points toward the exhaust.

which is forward

[FGR01]

Seriously, are you going to tell us what make/model/year bike we are talking about here or should we just keep guessing?

[tim512]

did you make sure you installed your new oil filter when you rebuilt it?

Did you make sure you used special green 2stroke oil when doing your break in?

Did you remember to reinstall your powerband on the powervalve arm?

until you give us some more details so we can actually help I'm just listing some general things you need to check

i dont think so ?

[tim512]

i dont think so

Well if you manage to install an oil filter on your 2 stroke, or a powerband on your powervalve, or find green stroke oil somewhere, then please let us all know ?
