I was told the quickest and one of the easier ways to get quicker acceleration and / or a bit more top end is to modify the variator on a scooter CVT. I myself am plenty satisfied with my acceleration. Even with my 260 lbs. 6 '2 self. But I would like a wee bit more top end. The only aftermarket variator I could find for a 257cc (260) Linhia engine was a Doctor Pulley Linhia " ATV " variator on Ebay. Now I know the Starter clutch for a 260 Linhai "ATV" has more spline teeth than a the Scooter 260 . I wonder if the variator has differences also ? And could I eeeak 5 more MPH with a variator and slider modification even so ? Any feed back fellow Scoots ? btw I go 63-67 mph now per scooter speedo. PS I've decided to go for a 32mm Performance carburetor instead of my stock 30 mm. And some Dr. Pulley sliders instead. Waiting on the 32 carb now. Haven't orders the sliders yet. One thing at a time I say.

Sliders would help. I don't know about the performance variator. High performance air cleaner and exhaust can provide a little more rpm and speed.

Yea tortoise, I only need 5 mph on top. everything else is satisfactory with this lighter than 400cc scoot. If I needed 10 mph I would see it your way. I can probably do 5 with no more than $200 I hope. A lot cheaper than switching scoots. And again I like the lighter scooter than the big maxi's.

I went ahead and sprung for the 32mm Performance carburetor with a 125 main jet (stock is 30 mm with a 110 Main jet). Usually more fuel doesn't improve top end in my experience. If it improves anything it usually improves acceleration. But sometimes it does give you a little of top end. Being an easy mod I am trying it first. Wasn't cheap though. Ever pay $100 for a Chinese carburetor ! Crymany ! The thing probably cost them $ 4 to make. lol I am going to try to run my stock air cleaner and exhaust. I have gotten very little gains from these mods in the past unless going extreme high performance. Mainly because these mods. make the bike to Fing noisy for little if no real gain.

Dr Pulley Sliders matching the stock weight or 1 ounce lighter is usually all thats needed. Dr Pulley will confirm the recommended size and weight if you email them. Before you start tossing hundreds on other mods you may find the $25 invested in the sliders may be all you'll need.

What do you mean by compatible with more displacement ? I wish I could afford a $500 upgrade if that's what you mean. A 295 cc with a little more cam and slightly larger carb would be all the scoot I need from here on out. A Herculean effort to pay for and build but a of a scoot it would be. Maybe this carb I'm getting and a set of Dr. Pulley sliders will have to be about it right now.

From the Dr Pulley/Union Materials Contact Us button on their web site. I just do a web search on "dr pulley" and select any link to Union Material and trim it back to the root which is www.unionmaterial.com/ and then select "Contact Us". This opens up your email client with a blank email addressed to "service@unionmaterial.com". |

In my experience, a larger carb can let the engine breath at higher RPM's but the low end suffers. I usually keep the stock carbs (I tune 'em, meaning I may re-jet if it's lean or rich), set the idle, keep the valves adjusted. By far the biggest performance gains and best bang for the buck on my scooters has been Sliders.
Running a ATV variator on a scooter is not a good idea in my option. I think you would get loads of low end, but loose a little top speed. If you can find a larger diameter variator and tune it, appropriately, then you could get 5 maybe even 8 more mph out of it.
Tuning a variator is a bit of black magic and voodoo. Weight of the rider, motor type, altitude and cycle of the moon tends to effect them. You need to tune it for your application, we can't tell you, this is the combo to run, because it's so different for each person,scooter.

I could be as simple as getting a taller tire Read more: itistheride.boards.net/thread/9619/mph-more-great-257cc-linhai#ixzz4GnzU25KCGot so much tire jammed in there right now it rubbed a little when I first put it on. On another subject, JR. from defunked Scoot dawg Forum put 12 gram DR. Pulley sliders on a 250A back in 2011. I'm assuming its a JCL MP250A which is exactly what I have. It was His wife's he said in the post. He said it ran great and went 75 mph. after 12 gram slider install "BUT" He never stated rider weight and height ,wind either. Mine would go at least 70 + with a short (all behind the windshield) 140 lbs. or less rider. it may even do his 75 mph. Anybody know if hes still around anywhere on these forums so I could inquire about such matters ? |
