Sold the Linhai 260 and bought a reflex. Carb PROBLEMS? By ultima (Read 871 times)

[ultima]

Well I sold the Linhai 260 and bought a reflex 250. It was apart to start with. When I went and looked at it, it would fire up on ether, the guy says it has been setting for a couple years (1200 miles) and not run. Anyway I removed the carb and all and leaned it real well. Re-assembled it and it started right up. I thought great lets put her back together and go for a ride. Well it has absolutely no power. It will not go over 30MPH. So I went back to the garage and figured I missed a vac line or the carb is still clogged somewhere. Removed the jets and cleaned again, seem clean to me. Fired it up same thing. It seems like it is starving for fuel. I ordered a cheapo chinese carb just to see what happens, the only thing is the Honda carb has a TPS on it and i'm sure the new one won't. I just figured i'd leave it hang there and see what happens.
So are there any of you geniuses out there that know what is going on here. It fires right up but no power. This scoot should hit 70MPH I would think.

And a Got a great deal on it $800.00 so long as I can get her running I guess.

Thanks in advance

Could be the carb diaphragm is got a hole, been sitting for two years it's very possible? Did you drain the tank and replace the fuel filter? Also could be a weak fuel pump? Sounds also like see or no see the high speed jet could still be clogged?

Any updates on the Reflex? Was the problem found and resolved? Sorry to say, but I think the purchase of a Chinese carburetor as a fix for the problem may very well have been a decision that would come to naught.
I'd be interested in the follow up to this.

A known issue with the Reflex, especially if it has been sitting a long time with less than a full tank of ethanol free fuel is rust in the tank. The rust can clog the fuel filter and impede fuel flow. The fuel filter is a pain in the butt to get to though.

The main issues I have encountered with any of my Reflexes were: Stator replacement X2, 1 of those were my fault by unknowingly getting salty water up into a connector on a ride during a winter thaw. I had hit puddles from the winter salted road melt-off. Of course severe corrosion occurred allowing a short to develop. At least that is what I suspect was the cause for that. The other happened when the bike was owned by my brother and the cause had not been determined.

Broken drive belt X1 after 17,000 miles of use (my fault as belt change really should have been done at recommended 12,000 mile scheduled interval)

Frozen rear caliper from excessive rust. (fault of neglect by prior owner)

Misdirected carb heating and air hoses causing coolant to make its way into crankcase via crankcase venting. (fault of incorrect reassembly/repair attempt by prior owner)

Plastics repairs after dropping the bike 2 different times. (OOPS! Happened when avoiding collisions and over applying brakes on non-ABS Reflex scooters) Other plastics repairs/replacements were done after purchase of damaged bike.

Had to replace old batteries a couple times, but such a thing was not really a failing of the bike itself.

Everything else has just been normal maintenance: scheduled oil changes, air filter changes, brake pad changes, tire changes, drive belt changes. (I put a lot of miles on my scooters) Coolant and brake fluid changes every 2 or 3 years.

I currently have 4 Reflex scooters so I am pretty familiar with them... though I have not encountered the diaphragm or tank rust/fuel filter issues myself.

Best defense against problems is following maintenance schedule of a service manual specific to the Reflex. Pretty easy to do since I believe scheduled intervals for service are much longer than for a comparable size Chinese bike. Something like checking/adjusting valves is often a "set & forget" item after the initial break-in period. Essentially all Reflex scooters are now used and most will have already had the valves adjusted at least once during its lifetime. Even so, adjusting the valves on the Reflex is a ridiculously easy procedure and getting to the valve adjusters involves only the simple removal of a small cover for the spark plug access. Once put into running order, keeping a Reflex going without issues is pretty easy. Its a fairly "bullet proof " scooter. That is why I like it so well.
