6.5 hp Honda Clone replacing spring, setting valve lash

[midnightwaffels]

I'm having problems starting it, I got it for free and its not starting I put gas and oil and cleaned the spark plug and the guy said it worked. so any suggestions?

[DeepFriedFuzzball]

@midnightwaffels Your engine could have a number of faults, first of all check to see if there's a spark, if not it could be the cut off switch is broken, there isn't enough oil in the engine or the oil sensor has failed, or the ignition / spark plug is faulty. If it sparks, check the carb, make sure it isn't clogged etc, and test with a drop of fuel in the cylinder and see if it fires. Also check the valves and make sure the engine has enough compression. hope that helps :]

what increase does the 18 lb valve spring inprove because I want more compresion in my engine

[cjz89civic]

@Codywombat

Springs will not increase compression but will allow the engine to rev higher, but with increasing the RPM's you run the risk of blowing it up. Check out oldminibikes com there are threads about these issues. Replacing the flywheel and the rod is a must with higher RPM's. Compression can only really be increased by milling the head. Then you run the risk of not being able to pull start your engine. Rod, flywheel, cam, springs, and a carb. True HP running close to 15hp in above

What does the rope supposed to do?

Is this much different than changing the spring(s) in a GY6 150cc scooter engine? Ity has two springs per valve, A smaller one inside a larger one. Do you know anything about a GY6 engine?

Hey I got a problem with my valves I replaced the springs and now the exhaust valve is clicking and only opening a tiny bit then after it clicks it opens all the way?? I put up a video it's called

"6.5hp clone valve problem" plz help me out???

[akinorhan5]

can you oil your valves?

[TheAssassin111]

Is it safe to use a straight pipe on a clone with stock valves?

[jmrhsdrummer]

thank you! very descriptive.

[duppyconqueror420]

do you need to use the rope even if your only adjusting the valves?

[cjz89civic]

@duppyconqueror420 No rope when adjusting the valves.

[drenth40]

good vid

[giffy5775]

Why did you put 2' of rope in the engine?

[defiythelie]

@giffy5775 to prevent the piston from moving.

FYI. I got 5600 out of my son's clone. no gov., K&N ,small track, 12-78 gear (muffler got knocked off half way thru the race) and a 90 jet. digitron showed 210 degrees.

I know that we "should" have better parts in it but that is against the rules, dumb huh.....

[Yelnuts71]

What is the gap for the stock OHV... Because my valves are loose in mine

[epger89]

whats the gap for the intake? the same?

[cjz89civic]

@epger89

.002 for intake and .003 for exhaust

[cat123456789101]

are you vette from OMB

[cjz89civic]

@cat123456789101 yes

[cat123456789101]

@cjz89civic cool, im cat123456789101

I recently upgraded my 6.5 hp clone with a header , new intake, and bigger carb jet. (and also bypassed the governor ) It runs like a champ now. I was wondering If it is necessary to change my valve springs to the 18lb ? What is the specific purpose of changing the valve springs?

[cjz89civic]

@matt127mia

When you replace the spings from the stock 12-13 lbs spring to a 18lbs you allow the motor to increase rpms. You will also need about a #92 jet to keep from going lean at the high rpms. And as with any mods you need to have a aftermarket rod and fly wheel for safety. check out oldminibikes on the net

[northerbrewer]

@matt127mia

You should not use 18 pound springs without a racing flywheel and billet rod.

Accidents with ungoverned engines are messy.

[cjz89civic]

It is not recommended to change the springs unless you have installed a billet aluminum rod and a Billet flywheel. Your engine should not really see more than 4500 rpms with just the governor removed.

[MrGiantstpss]

is really worth all the trouble if i just ride mine around the yard? I took my governor off.

[donaldrox]

man i wish changing briggs animal springs were that easy. i have to rent a spring tool and i have little keepers to keep track of. i do have a clone on my mini bike so this should help thanks for the vid
