    The engine seems fine, it's just that the RPM'S have to be increased to about 1/4 to 1/3 throttle before the scoot starts to move. I'll take the belt off and clutch apart and check the rollers to see if there's any wear. I just bought it and don't know anyone else in the area who has one. Where's the best place to buy parts online?

    Thanks

    Also, I will probably be picking mine up from the shop today. I had swapped a '84 125cc drive train in place of the 150cc after trashing the spline on the shaft from the crank to the CVT.:cry I was stranding me after 10-15 minutes of riding after the swap and going thru batteries also.

    Battery wiring on the donor 125 drive train was fudged. A fellow rider helped me put MUCH larger terminals on the wiring, but the weight and vibration trashed two batteries - THE BATTERY TERMINALS WERE ACTUALLY FRACTURING!. I had the shop put the right size ring terminals back on and they replaced the spark plug with one of those 'Iridium' types.

    Also, near WOT, the speed could sometimes vary without a change in throttle input from me. Had them put new variator weights in. They added a paddle switch for the headlight, so it lights up again. Now I can start the bike without having the headlight on.

    ALSO - it was still running like crap when I went to pay the bill, so they kept the bike. The last thing I heard them say is that it might have been the coils.

    Wrong - another cheap fix! They replaced the plug wire - that fixed the driveability issue. So check your plug wires also if it's still running like crap.

    I can't wait to get it back - it will be reliabilty for the first time since I trashed the splines in 2007.:clap

    Well, I went to the shop to meet the owner and the bike wouldn't start, not only that, it was backfiring.

    Whenever your Elite backfires, that means one thing - you have, or have previously just destroyed your exhaust gasket. It's about a $5.00 part and a 45 minute fix.

    So the scooter is still there.

    But here is a picture of the donor cycle for the drivetrain.

    And here's my Elite after the swap, one of the times that it stranded me post-drivetrain swap.

    I was wondering how difficult it is to clean the jets or to rebuild the carb. Any thoughts on the Chinese Carbs on Ebay, Honda dealer says crap. If I bought a rebuild kit is it something I could do, I've replaced the belt and brakes myself so far.

    I'm still having performance issues, intermittent power. When runny poorly the acceleration is flat, and it tops out around 45 mph. Seems sluggish, after I've ridden it for a while and restarted while warm, or when the weather is warm (over 80) it will run normally (either right when i start it or while riding). I've taken it to 3 shops and they tend to give me the response "seems to run normal" (honda and two others) even though I tell them I know it is not and that it sometimes runs at "full power". frustrating.

    The idle can sometimes spike (intermittent) to the point where the clutch almost wants to engage. Usually when it is warm for a while the idle will return to normal

    15000 miles

    I have:
    replaced the belt
    valves adjusted, checked for vacuum leaks, replaced a gasket. -by Honda shop (they say it seems to run fine :()
    checked by two other shops previous to honda
    replaced battery and rectifier
    replaced air filter
    replaced tires (dont think exhaust gasket was replaced)

    Have not:
    cleaned carb
    replaced roller weights
    replaced clutch shoes
    replaced bearings
    replaced petcock

    noticed:
    while running and when i put on to main stand while parking... the idle drops and sometimes stalls.

    I have the same problem with my 87 Elite 150- it absolutely tops out at 45. Seems to run stellar other than that. The rollers and belt are in spec. I am thinking it has got to be a carb problem but that has been replaced so I am a little stumped.

    I have an Elite 50 that is faster- I am wondering if the 87s were intentionally limited for some reason. I am really beginning to think that the variator may be undersized to keep top speeds down. From what I can tell the belt is fully reaching the top of the variator and so I think that may be limiting top speed.

    Please update if you make any progress and I will do the same.

    Thanks,

    I like that yellow bike, Cameron.

    Throw one or two ounces of Seafoam

    in the gas tank. That will help ungum the carbs.

    My 150 with the 125 drivetrain tops out at about an indicated 52 - which means 50mph, since the speedometer is always 2mph optimistic.

    Make sure your spark plug wire is good. Make sure there is no air leaking in where the carb joins the boot. Exhaust gaskets okay? Mine needs to be changed.

    I have worked a many of these ole tanks. I have 150 + 250.
    I had all panels sprayed ( painted ) by LineX as well as spraying rubber coating on back side of old panel. Makes them much stronger and maintenance free. I re-dyed all exterior plastic and rubber with Renew Protect (.com)... even seat and grips.
    New carb, all springs upgrade, 9.5 gram sliders, open exhuast tip (1in), much larger tires... Ch150 will hold 70mph... even maintained 45 UP Blue Ridge Parkway.
    Any one found performance cams for these old GY6?

    My 1986 elite has a top speed of 66mph, could just be condition, elevation or something along those lines though.

    Don't forget to derestrict your muffler----it was a weld-bead in it & needs to be filed smooth. Keep your shop-vac on hand to help prevent shavings going into the exhaust---doubt it matters but I kept mine very clean throughout the process.


    If the temperature in your area exceeds a 45-95 degree temeperature range, then you will definitely want to consider getting a few different main jets for your carb. If you ever increase/decrease a main jet by more than 2 sizes, also increase/decrease the pilot jet size by 1.


    IMO, a 1987 CH150 should be hitting 60mph no problem, with a few simple mods. untouched & fully stock, yep 58mph is about an ideal top speed. You should be experiencing almost wheelie-popping torque off the line, though, even bone-stock.


    Something also i have noticed regarding lagging performance: I put SLIGHTLY LESS than the recommended amount of oil, IMO the recommended amount seems too much & can be slowing things down. Consider a lighter oil as these scoots don't really run very hot anyway----i switched from 10w40 Pennzoil to a 10w30 Quaker State & I do notice the difference. You may also need to change a laundry-list of bearings also, CERTAINLY your wheel bearings; a bad wheel bearing will cause lower top speeds & will make your engine work harder for nothing. The integrating bearing on the driven face was shot on my scoot, caused me to snap a driveshaft, whilst replacing ALSO found some bad bearings inside with the gears. ..


    VERY IMPORTANT!!!!! When you change your tires ALSO CHANGE YOUR VALVE STEMS! A new tire is nice & safe but if you keep the same cruddy, weather-beaten valve then you risk that sucker blowing out while riding. . .not good.




    I'm actually SURPRISED nobody mentioned anything about bearings up to this point. . ..!

    wow, this thread has all sorts of great info for CH150 owners.

    I just added sea foam to my fuel.

    Can I add seafoam into my 4-stroke oil as well, or is that a bad idea?

    I wouldn't adulterate your motor oil with anything, not Seafoam, not B-12 Chemtool, not STP Oil Treatment, not Marvel Mystery Oil, not WD-40, not the sweat of 1,000 virgins, NOT ANYTHING.

    So don't mess with your oil. Keep it clean and changed regularly. That's all you need to do to it, besides checking the level on a regular basis.

    Hey guys,

    Bought this '84 CH125 Elite last week with no known past history. It fires right up, but I think the gas might be a bit old. Anyway, to do some light maintenance. Before riding it, I changed the oil and spark plug. Got a fuel and air filter on the way but the air filter actually looks clean.

    So I got it on the road to take it out after doing this, and it struggles to even go over 30mph. These should be capable of 55mph from what I know. Apart from this though, the thing seems to run great. Fires right up, idles great, and no stumbling. Wheels spin freely when up on kickstand as well...Any ideas?

    I also put seafoam in and rode it around about 1/2 mile but still no difference...

    You have to get rid of the old gas. If you just top it up with new, and seafoam, it will run badly for a tankful. Then fill it again, more seafoam (like an ounce or 2) and it should get better. After a few hundred miles things should be back up to par.

    Be very careful with those old dried out hard tires. They can kill you, and ruin your scooter, when they pop at speed and you go flying.

    carb with gunk in it. clutch, drive belt, rollers might need looking at. New drive belt off the net is 22 bucks, clutch drive face about 100 bucks . Start with the carb. If you look through the threads here someone did a strip down and rebuild . They posted pictures of it. It took them 3 or 4 days . I would do the above anyway if your going to keep it cheek out the drive train, carb etc. As for the tires anything with a date code of 3 years old should be change. They are only 20 bucks to buy each. Takes about 2 hours to take the wheels off, take them to a shop and have them put new ones on. Cheaper the 5 grand at the doctors.

    My Honda Motorcycle ID Guide tells me that '85 was the first year for the CH150D in the USA. My all original DeLuxe with less than 6K on it has a VIN that ends ...00035. So I'm thinking it is the 35th Elite 150 made. Would be interested to know what your 1985 Elite's VIN is? I'm the second owner, mine lived in Mammoth Lakes, CA the first 20 years of its life. I'll post a picture when I'm on at home later.

    After getting a ride from the nearby grocery store in a stranger's pickup with the Elite earlier this week, I resolved to see if I had a spare spark plug wire/coil assembly.

    I did.

    The bike starts much better and doesn't stall nearly as much. However, I still see little black pieces of crud floating in the gas tank, so I need to drain it, clean it and put a new fuel line and filter on it. I had to ride it a bit more so I put $4.00 bucks worth of gas in it earlier tonight and put another 12 miles on it. It wants to still stall when turning (especially right) from a stop at an intersection. And it still does a least once a time when I am riding it. So it is still a work in progress - but it is getting better.

    Are these crashbars available for an 85 CH150 Deluxe? Where does one find them, if they are still available? Thanks! Mario

    I would guess someone made up a set. I ve never seen or heard of them before.
