running in with lightened flywheel...

[razor-]

Hey.
How would i go about running in my pb that has somethin like 3/4 fins completely off?

Because for the first tank of fuel it would be practically ideling the whole time wouldnt it??

Can somebody pls link me to a good guide on running it in..

Thanks

[barnsey]

dude i would say its a fuel or sprk problen did you remove the fly wheel when you removed the fins?

[razor-]

wat??
I havnt started the bike yet... Im saying When i do run it in im supposed toi be ideling it for the first tank of fuel arnt i? which wudnt b a good idear for a bike that has a lot of the fins off..

Yea of coarse i took the flyewheel off the bike when i chopped the fins off

[barnsey]

oh i see i read it rong soz..lol ...um well you still ride it just not flat out it shouldent matter it realy olny is bad if you are just sitting there for ages letting it idle if you are ridning its ok just dont sit there for a period of time idiling unless ur warming up the engin but i wouldnt worry

uh kk..
so when im runnin it in do i just only give it a little bit of throttle and not twist it fast?

I didnt run my standard engine in i dont think because when i took the head off it was cracked on the inside

[barnsey]

yer give it smoth throttle and dont reve the its tits of rev it a bit occasionaly than on your second tank go a bit harder than bbasicaly as hard as you want 3+ tanks

this is what my yz250 manual says... obviously a pocketbike doesnt have gears though..

1. Before starting the engine, fill the fuel tank
with a break-in oil-fuel mixture.
2. Perform the pre-operation checks on the
machine.
3. Start and warm up the engine. Check the
idle speed, and check the operation of the
controls and the “ENGINE STOP” button.
4. Operate the machine in the lower gears at
moderate throttle openings for five to eight
minutes. Stop and check the spark plug
condition; it will show a rich condition during
break-in.
5. Allow the engine to cool. Restart the engine
and operate the machine as in the step
above for five minutes. Then, very briefly
shift to the higher gears and check full-throttle
response. Stop and check the spark
plug.
6. After again allowing the engine to cool,
restart and run the machine for five more
minutes. Full throttle and the higher gears
may be used, but sustained full-throttle
operation should be avoided. Check the
spark plug condition.
7. Allow the engine to cool, remove the top
end, and inspect the piston and cylinder.
Remove any high spots on the piston with
#600 grit wet sandpaper. Clean all components
and carefully reassemble the top end.
8. Drain the break-in oil-fuel mixture from the
fuel tank and refill with the specified mix.
9. Restart the engine and check the operation
of the machine throughout its entire operating
range. Stop and check the spark plug
condition. Restart the machine and operate
it for about 10 to 15 more minutes. The
machine will now be ready to race.

ok so about every 5 minutes turn it off untill it cools?

[barnsey]

i guess lol

yeah razor.Do what hoover has printed.But forget about the dismantle thing and the 600 grit paper.Just put 25:1 fuel oil for the first 2/3 tanks.Just dont hold it flat out.I no its hard to do.But in the long run you will benifit from it.
