Linhia 257cc , Screwed it up by putting a 32 mm so called performance carb on it. DON'T DO IT ! Stay stock carb and rejet on this particular motor I say. And I was told BTW

I feel I should cap this 32 mm carb fiasco off with this. Get this, After all this I put my 115 main out of my old Jap 30 mm carb in the new 32 mm , New carb ran great then ! But no better readings from the tach and speedo than my old carb. I think it had a sleight edge on my old carb in the mid range. But not enough difference to change much. So what that means is if they will take this 32 mm back I want a refund. And the old Jap 30 mm goes right back on with no more than one jet size higher or lower than stock. , It might even run the best with this 115 main jet it came with

My first problem was my main jet fell out in the bottom of the float bowl, Holy crap I feel like a total YO Yo. I guess in all the junk I was screwing with that day I forgot to torque the 115 main jet I moved from the new 32 mm carb (trying to get it working) back to the old 30mm carb. Anyway, I got it running good again except for my float bowl running empty often. Seems this fuel pump I bought off Ebay just isn't enough. I will return it. I don't want to go electric fuel pump like a lot of 250 and up guys do. I got another Vacuum Jin Bo Chinese fuel pump on the way. Hey, The last one lasted almost 8 years before it quit. That's good enough for me. It is somewhat equivalent to a Mikuni DF 52-21-D fuel pump. But under half the price. I'd like to adjust my valves and pull my cover and mark my variator while I'm waiting for my Fuel pump Read more: scooterrebels.proboards.com/thread/2676/miles-hour-257-linhai-jcl#ixzz4IgvWXpdw |

While I'm waiting for my fuel pump I'm making a trap door to get to my intake valve easy. I made one years ago to get to the exhaust valve. These Linhia's with receding valve seats (exhaust valve mainly) need valve adjustments often. And since the engine lays down the exhaust valve is accessible from the belly and the intake has to be accessible from under the seat. If you don't make these access doors or holes you would have to take off all the body work just to get to the top and bottom of the cylinder head to adjust the valves. The trick is to make these mods as invisible as possible. We wouldn't want to louse up the beautiful lines of a Reflex clone would we .  |
