150,
Take apart your top end and everything will be black.  over time that carbon builup will start costing you power and cause your rings to wear out faster.

ok wat oil do u recemend i use i was thinking maybe belrary?.but what i meant is put some in my 65 only. the 150sx gots yamalube in it because wen i bought the bike the mechcanic put that in there.and the guy said use 24.1 for the for the first 5 gallons for break in use...???????  

Yes Bel ray H1R is great stuff.

Your mechanic is spot on.  During the break in period you bike will need the extra oil to really penetrate until all the parts start to wear together.

i use golden spectro SX2 its in purplish blue bottle.   its awsome!!! run it 32-1 to 36-1.  i use a br7es or br7eg spark plug. and it looks perfect and runs perfect.  i have a 125 and never foul out plugs  

stop giving bad information. a br7eg is way too hot for that bike. stock is a br9eg. if anything use a br8eg on tight trails and br9eg on open trails, or just rejet your bike so that it runs correctly on a br9eg.

ok thanks for the help man i was worried for a moment u know. lol. ima go to my shop and buy some  tomorow.....the bike is already quick at half throtle it gots some torgue i cant imagine how fast its gonna go when its broken in and when i go full throtle on this bad boy.man i bet people are gonna stare at this bike when i go to the the track with this thing...  

elko:im not gonna use the bike for trails man. im using the bike for    track and off roading so the stock plug is good i think..but i dont think i need to rejet the bike man... .  

no that was to 2007cr125. he said he uses a br7eg in his bike when he should be using a br9eg.

Your mech is right in puting in 24:1. But only for one tank break in. 5 gallons is 2 tanks.
not needed and can cause fouling. And drop in a new plug after break in. As for what plug? Read your manual and you won't go wrong!
I'v broke in many new bikes and my bikes are good to go. And use Bel Ray H1R 32:1. Also flush your trans oil after the tank is gone. Replace with BelRay Gear saver to spec and you will be good to go to   Also gease your barings stearing head swing arm ect...and re tighted your spokes and adjust tire pressure and chain lag after break in. It will need it.

thanks yz woods ur a lotta help man....so put 32:1 for the second tank......and yea ill tell the mech to grease my barings and everything cuz i got this one deal for about 2 years where the mechcanics fix my bike for free every time theres somthing wrong with the bike yay for that =].so i dont have to do the hard stuff for the bike for now  

oh yea how many tanks or hours does it take to break it in......  

Bel Ray H1R is the best but i run Pro Honda HP2 because it is a lil cheaper

The only reason a four-stroke can beat a two-stroke is because of the double displacement advantage

there is a thread on how to break in an engine. i use 32:1 because you need the rings to sit right and the break in period is the time to get the rings to sit right and i feel if you use anything richer then that then they wont sit right.
