Huzhou Daixi Trike 150 or Ice Bear Slipping By sunnydayfly (Read 10,975 times)

I have a 2009 Huzhou 150cc Trike. I understand that this is the same bike as Ice Bear and some others. When coming up to speed say 25-35 mph it feels like it is some how shifting...the engine races a little and it jerks as if shifting into another gear. If you come up to speed slowly it does not do it. But when pushing to say 50 mph it does it. Almost as if clutch is slipping then grabbing? I'm new to this forum but have turned a wrench for 45 years on various bikes and autos. Any help or ideas anyone could give would be greatly appreciated. Bought this bike used and was told it was doing this but price was tooooo good.

Yes, it sure sounds like it is slipping if the revs go up and it does not pull. Take the CVT Cover off and check the belt. Usually if its the Clutch it will jump or shudder when starting off, so I suspect it is the belt. Which Trike do you have MODEL wise, if its from Ice bear it most likely has the Short Case which then the belt will be a 743-20-30 and get a BANDO belt they are thicker and last a good long time.

As you can see I have the PST150H Trike from Ice Bear.

Mine is exactly like the one in your photo on the left. I think it is called mc101 You are right it shudders when I take off. Do you happen to know the size of the belt. One other question the guy said it had a makuni varator. I don't know if makuni makes a varator??? I'm at 223 # what would be a stock roller weight for me. Not exact but best guess. I do a lot of riding on long roads want to keep it in the rpm power curve.

They usually come with 10g or 10.5 gram weights, and if you find that is is reving around 8000 rpms that is what the weights are. I run with 12G Dr. pulley Sliders which should bring you down to just about where you want to be, near 7500 rpms at wot.
How many miles do you have on it? And does yours have a revers or NO reverse/

Thanks for the info. It has 350 miles on it. I also checked the chain it was like a bowstring. I think the play should be about at least 1/2 inch. It also has reverse on handlebar. Will probably disable that. bike is easy to roll. The chain was so tight that the rear axle made a creaking sound when rolled by hand. I have to work this weekend at a gatehouse at a corp of engineer day use park on the lake but will be checking everything out tuesday. I'm 67 and to old for engine games but hey you have to do something. Thanks again

HEHEHE!! Well you are right we have to do something I AM ALSO 67, going on 68 this year.
Yes you are correct the chain should have about 1/2-3/4 inch play when you push on it in the center. But just take the 4 screws off on each side of the fenders and then the fenders and center section comes off as one piece. Then you will have access to the bolts to adjust the tension on the chain.
You have to loosen bolts on the Brackets so that the entire axle can be moved in our out. Then you will see 4 adjusting screws sticking down, turn each one evenly like one turn at a time. Make sure the chain is straight from the front sprocket to the rear sprocket. If you have a good eyeball you can see if it is straight or you can get a piece of string and tie one end to one of the teeth on the front sprocket and then pull it back to the rear sprocket. If the chain is and rear axle is aligned the entire length of the chain will touch the string all long its path.
Then tighten up the sucker and your set.

Sometimes I think the kids feel that we should be in a wheel chair sitting in the sun with a pretty nurse dabbing spit off our chins with a hanky. I think I'm busier now than I was working. I will adjust the chain check the nuts on the rims and look at both varator and clutch also will check out belt closely. In another post you talked about the missing radial bearing? I don't think this problem and that one are the same but its possible just a different symptom. It only slips for an instant and jerks. It really feels as if yolu are speed shifting a car.

I doubt very much that the missing bearing is causing your issue. I agree with Alley about a CVT issue. We have had that issue and it was a glazed belt.

I kinda like the idea of sitting in a wheel chair with a nurse but, not dapping my chin! LOL! I am 57 going on 58, going on 21! LOL

Glad wives don't read forum. I think I know about what you meant about
nurse........ DOM ...It doesn't sound like the problem with the bearing. I ordered a couple anyway the #6004. it does seem to shudder a small amount when first accellerating. This is the first trike ive had. I have a honda elite 150 for my work scoot. Runs pretty good. No problems with it. Guy that originally worked hard to find problem but never did. He had the chain really tight I guess his thinking was jumping sprocket. I'll check out tuesday and post result. Thanks you guys the help is really appreciated saves hours of troubleshooting.

[sunnydayfly]

Got everything checked out chain is perfect, put new dr. rollers in varator, got rid of reverse....everything is good no slipping or jumping. Now my problem is I'm turning 8900 rpm at 50 mph. I need to hold the rpm down to about 7200. Any suggestions would help. Also 3200 when clutch starts to move bike. I believe I need lighter clutch springs
