Recommended Valve Clearance

[!bmth!]

so im sure you all know, but if you dont i have a pitpro 140le with a yx 140 i wanted to know the recommended valve clearance height for this engine, i've watched many of tutorials on youtube so im confident with doing it i just dont know what to set my valves to, and the videos i watch all had different clearances eg . 0.03 or 0.05 or even 0.06

!bmth!

.003 and .004.... also there is tonnes of threads on this already mate... look a lil harder and it saves everyone time.

Carlton

0.003 for inlet and 0.004 for exhaust

thanks guys i just wasn't sure, i shall do my timing and clearances tomorrow as im not happy with the way my bike is running

 

[!bmth!]

sorry to double post but i just looked at my dads feeler gauges and the .03 and .04 are like thinner than paper is that right ?

 

[Carlts]

Hey mate the thickness of paper ranges from .002 - .006 of an inch so yeah the gauges being .003 and .004 should be bout as thin as paper

 

[!bmth!]

im confused on my dads feeler gauges it have two sets of number on each guage so say there is 003 and on that there is 0.08 so which is inches and which is mm

 

[Carlts]

Hey mate the .003 will refer to inches and the .08 will refer to mm

as 1 inch = 25.4mm

Use this site to convert inches and mm:

so i did the valve timing but when i did up the cam sprocket cover the bolt broke inside the cam sproket cover so do you guys know where i can buy one? i have looked on pitpro and dhz and rung up pitpro and no one has any

 

[!bmth!]

sorry to double post but heres what i mean about it broke off in the cover

Try a bolt shop. Just take in the broken bolt.

 

[!bmth!]

but what about the broken bit that's stuck inside the cover

 

[MiniFighter]

measure the cam cover's OD. i have a few spares at home ill post em to you.

 

[!bmth!]

well it has a little taggy thingy that pokes out which makes it about 8.5 cm...about. i will be very greatfull aslong as you have the bolt with it aswell

Just use quickout's mate. Drill a whole in the middle of it and use a quickout. Job done.

Drill it out. Just use a smaller sized drill bit so you dont stuff up the threads.
