JCL MP250A Lihai 257cc powered / The CVT is why I went to scooters. I'm 53 , I'm done doing burn outs and wheelies. And I believe a CVT will accellerate just as fast as a gearbox barring and all out holeshot.

JCL MP250A Lihai 257cc powered / The only thing I can think of that your plan does not allow for is there should be variations in your rpm while breaking in. You are not supposed to be at one constant rpm while an engine breaks in. Constant rpm makes more heat than an engine accelerating and decelerating here and there. Higher operating temps are not an engines best friend while breaking in. Aside from that AFAIK there is no law that says an engine must be under load while breaking in.

JCL MP250A Lihai 257cc powered ? Yea, lol I think I was witness to what you are talking about . I remember a guy on here recently that wanted immediate service Dag Nammit ! I got like that a little not to far back myself. I had started about 2 or three threads on what I thought were halfway intelligent questions. , no one even commented for days and days it seemed. So I checked other places on this site for activity thinking this site might have went the way of ScootDawg. No, the only activity I could find were guys trying to peddle 25 cent widgets for little 50 cc scooters and such. I thought all intelligent life must have left. Slowly but surely Comments started trickling in though. I don't know where everybody was ? I think it was around Holloween.

I know this is off topic but this Dell has Windows Vista and works just fine. Of course the AMD Processor stinks but I can live with it. Maybe something else is off kilter. Have you tried another Browser? JCL MP250A Lihai 257cc powered / I have Windows Vista too. The memo should have said "change browsers". It said I must "Update Browser" . My girlfriend just changed browsers to Google Chrome and all is well now . |

Use grade 8 or better on all your fasteners from now on and those kind of problems go away,,, look in the area phone book/ internet for aircraft breakers,,, they sell aircraft grade fasteners by the pound,,, last time I did that I spent $70 and I'm on my 15th build with much left over,,, worth every penny JCL MP250A Lihai 257cc powered / Then where do I find a nut to hold my variator on my drive shaft on my Linhai 257cc ? It is M14 in size but thread is non-hardware store available . Mine is getting aweful mushed up from being to soft a metal and me taking it on and off to do weight changes. I hope I can even get it back off the shaft to change it out. |

a word of caution when doing engine tests on the centerstand. as the rear wheel turns, there will be some RPMs that will make the back of the scoot "hop up and down". if this is severe enough, it will pick the scoot up off the cenerstand and the spring will fold the stand back up under the scoot. the effects of this will not be good and could cause a great deal of damage. so, keep your foot on the centerstand kickdown peg at all times while doing engine RPM tests. JCL MP250A Lihai 257cc powered / I'm 54 yrs. old. You think I don't know better than to launch a scooter through a sliding glass door   |

JCL MP250A Lihai 257cc powered Also another nice benefit . Engine braking when decellerating has improved at least 40 % IMO.

I was looking for a windshield for my scooter, and sent a message within the board to fugaziiv, who is apparently the "Parts For Scooters" guy. He answered me quickly, and, after a few questions back and forth, I ordered a Slipstreamer CF-50 on Monday - I got it yesterday (well, I am directly across the state from them) - installed it last night - and all is good! A shout-out to Parts For Scooters and their friendly people - Matt, Tom, and Susan (?) were the ones I dealt with... Rumor has it there will be a Cyber Monday sale...  JCL MP250A Lihai 257cc powered / What state ? Oh, I had to Edit. I just saw the St. Petersburg thingy. Never Mind |

4950,,,nice find on the variator boss,,more than a few members here could benefit from "blue printing" their drive line,,,there's a bone right there JCL MP250A Lihai 257cc powered / I learned it from a GY6 150 cc Ricky Racer. I then confirmed it might work on a 257 Linhai when I did a variator test on my JCL on the center stand. I turned the accelerater to highway speed 6500 RPM and noticed my variator wasn't squeezing the belt out to full diameter with no load. Figuring more might be better , I revved it even higher in RPM to 8,300 " NOT RECOMENDED" The Linhai burbled a bit at that speed like the valves were trying to float . BUT the variator still did not achieve full movement (belt clear out to edge of pulley) or top/ high gear. So first checked and made sure the belt was long enough to allow full movment of variator. It was . Next, Took the variator apart to see what might prevent it from full sqeeze so to speak. I discovered while simulating what it does while in use with my two hands that the boss was a bit two long to let it collapse all the way. I ground it from 61 1/2 mm factory length down to 58 1/2 mm . Bingo ! Got full movment from my variator that quick. To anyone who wants to try this I recommend grinding only 2 mm. I think it will be just right. Don't rev your Linhia like I did. I had coil and CDI mayhem for weeks till I finally got it sorted out again. Take my word for it. 10 to 12 gram sliders, And shorten your stock variator boss to 59 mm . Do nice work though. Remember, they also call a variator boss a variator bearing. So make sure your work is sqaure and smooth in the end. With this mod the lighter the rider the faster he or she will go top speed. With very good accelleration also. Took me weeks or more to come to this. |

JCL MP250A Lihai 257cc powered / I know what scooter I want now when the time does come though. I really like the Kymco Downtown 300I . If it doesn't fit me I would totally redesign the seat to give me more leg stretch if you know what I mean. I don't mind any wheels that arent below 13 inches. My JCL has 13 inchers with Pilots on them and I can ride the do do out of it. And I'm really not crazy about that modern Euro look that Sym and other Kymcos have.
My friend, I fully agree about the engine mods. CVT tranny scooters are quite different from motorcycles like I rode for 50-years... Many members including myself, have gotten far more performance improvement from tweaking the CVT transmission that coaxing more power from the motor. I think you might get almost what you want simply by switching the rollers in your variator with Dr. Pulley sliders. Next season, I plan to do that on my Kymco 250. Most riders here who switch to sliders are riding 50's and 150's but a few have done the switch on their 250's. Most got better acceleration, hill-climbing and top-speed/cruising speed AND better gas mileage too. Talk about a win-win-win situation!
Any riders who've done the slider conversion on a 250, PLEASE chime in here with WEIGHT recommendation. Getting the right slider weight is absolutely critical.You can usually do the change-out yourself with just hand-tools, and the sliders should cost less than $50. MUCH more "bang for the buck" than any engine mod. Usually you don't even need to change clutch springs. Keep in mind, a 250cc engine is only 15 cubic-inches in displacement. When I was young, the Italian-made Harley-Davidson Sprint 250 won races, and it had 15hp: one hp per cubic-inch. THAT was considered red-hot in the sixties! So even though many of today's 250's put out more, the least-powerful Chinese 250 still puts out that magic 15hp or better.
They have enough power. They just need a better setup getting to the rear wheel.You probably already have a pretty good scooter there, and just maybe, the right weight of SLIDERS could be your "icing on the cake". It's affordable enough to be worth a try. Just be SURE the weights are right for your scoot. ADVICE NEEDED HERE! For my Kymco slider weights too...Leo in Texas PS: And, yeah... That new fuel-injected Kymco 300 is the "cat's azz" for performance, and doesn't fit anybody... LOL! Except ME! LO not so L. Fits me like a glove... Wish I could afford one. The original owner of my old "Minnie Mouse" traded her on one. Oh well, no room in the budget, and the old mouse is a great scoot for me. At least when some Bozo bangs it in the parking lot at Wally World, he's not scratching new paint!  JCL MP250A Lihai 257cc powered / If anybody is wondering why I am riding on someone elses quotes all the time it's because it says I can't post my own post because my browser is out of date. I guess Windows Vista can't be updated in anyway to make it work either. Anyway Oldchopperguy, I have shortened my variator boss 3 mm to make my variator compress all the way, and put 4 eleven gram sliders in and 4 twelve gram sliders in. I lose a pinch of holeshot performance . But 10 mph and above It gave very nice midrange power and smooth acceleration to 68 mph unless there is any extra resistance . Like strong headwind or pulling 5 % grades or more obviously. |
