GY6 Trans Problem

[DocHemi]

Ok guys heres one for ya... Never ran into this before.

Have a CF150R...

On level ground, or downhill, all is fine,

But on full acceleration or going up a grade, especially on asphalt; at full power...

It feels like the cluth gives out for a split second, then bang picks right back up, does it wasrm or cold.

It has new stock drive and driven units, and new belt, stock weights and spring.

What would you try to change out first to fix the problem??? Clutch Spring? Possibly scuff up clutch drum and/or clutch friction material?

Help never seen this before!!!!!

Is this a real honda Gy6?

So are you saying the clutch sticks or slips?

[DocHemi]

NO IT IS A HOWHIT CLONE GY6

Its not really a slip, but it just "bang" you feel it stop for a plit second and then catch again.

Sounds like a broken gear, or worn gears.

If F-N-R is actuated with a splined sliding collar, which engages either the F or R gear, the tabs could very well be worn. Ive seen this on machines where people put it in gear, then goose the throttle to make it "pop" into gear

The chain is slipping a tooth under load. A frequent problem due to flexing of the chain tensioner.

The chain needs to be tightened. If the chain tensioner has the little rubber grommet underneath the nut, that's gonna have to go.

NEGATIVE.....

This cart does not have what you mention...
to tension the chain you tighten a long bolt that raises or lowers the engine cradle in relation to the axle shaft.

That was my original thought, and I even over tightened the chain (no slack), to check and see and no good (of course i did loosen the chain a bit).

I still maintain that it is the F-N-R portion that is the problem.

What im talking about, you would put it in gear, push the GO pedal, and it would roll off, and when any real torque is applied, it sort of stops pulling and pops for an instant, like you were climbing a hill and hit a small patch of ice.

May look for an adjustment in the shifter linkages, to make sure it is pulling into gear fully.

[DocHemi]

Yeah red you hit it on the head, funny tho it on seems to do it from about 75% power on up, but doesnt seem to do it on flat.

I know the F-R gear box is a plenetary unit, and has no reverse.

Think I may just pull it appart and see whats going on in there.

NO IT IS A HOWHIT CLONE GY6

Your reverse cable needs to be adjusted, i had and now have the same problem.


Next time call it a Howhit, CF moto doesnt make a Gy6 so it doesnt sound correct.

CF moto is a company that makes the CF 250

[DocHemi]

I'm not sure we are talking the same lingo here....


By CF150R I meant.... a Tomberlin Crossfire 150R

well, in the buggy world we dont call our engines by the company who builds the buggy, we call it by the company who makes the engine, in your case, howhit. Even at that calling it a Gy6 is enough.

[Red-85-Z51]

If you call CARTER and tell them you need a part for a Howhit 150..they will hang up on you.

If you are a dealer and say that, they will revoke your dealer status.

If you say "howhit, tomberline, GY6, China, etc) to Carter, they will really lay into you about how they dont use those engines...

Parts from a Tomberline Crossfire 150 will usually swap into a Carter 150.... They both use the Howhit manufactured Honda GY6 150cc clone engine.

[DocHemi]

I thought I had posted a follow up to this post months ago, but apparently not.

Yes Doc, that would be your chain tensioner.

Is this a real honda Gy6?

So are you saying the clutch sticks or slips?

Mine is doing the same thing.. I got the F-N-R unit apart and it looks great..works really simple..drive gears apart also looks great.. . Can't figure it out. Anyone have any issues with the belt or variator causing this issue?

Illbuell, you might be better off starting a new thread as this one is an old thread. Check the dates.
