i ordered a keihin carb for my 07 trx 90 and it fits nicely but the new cable they sent is way too long and i can't make it work. the old honda cable cap [that fits on top of the carb] is too small to fit. the keihin cap is approx 3/4 or 19mm. honda cap is more like 1/2 in. the keihin has a rubber boot on the cap where the throttle cable goes through . i don't know how to find the right length [most cites don't give the length]. i'm not sure how cables fit into that boot and do i need to add the length of the boot to the cable? the old honda cable is 28 inches total, but the cable movement is only approx 2'' which would not be enough to reach the actuator block on the keihin. looking to find a throttle cable compatible with the keihin. any help, please.
got 7 atvs off CL recently for a good price. one of which is a yamaha warrior. anyone know where the vin is printed on this bike? Haha good place to start as I do not know year or size yet. The former owner says needs exhaust ans and clutch work. he said it ran fine until the clutch cable broke and then I couldn't get the new cable adjusted right and it would grind gears. things I see: clutch cable locked up again, no brakes, carb leaking (green with algae around the bowl and has gelled gas stalagtights on it), aftermarket exhaust melted the airbox so I need something different and a new air box. I would like the use the current exhaust if I can but I have a feeling its a redneck fix as it looks like there is an ace bandage holding it to the exhaust pipe (its an aftermarket slip-on exhaust), so I'm not sure about that- lets get the bike running first. also, battery (looks brand new, what a shame) is dead, 0 volts. Otherwise, bike looks to have not been wrecked, and plastics are ok (it sat outside under a 'tarp' for 3+ years since it was run last). any tips and advise on where to start first would be awesome as this is my first clutched bike (manual).
the clutch is my main concern- I've never rode a clutched bike so I dont even know what its supposed to feel like. lol I'm spoiled on my automatic polaris
So I bought a Bayou 220 as me 'Black Friday' score, and was informed it has carb issues..
A little history from the previous owner: they suspected the carb was bad as it was 'running like crap' so they did a rebuid kit on it. Didn't fix issue so they took it to a shop where the tech installed an aftermarket(?) carb, but had to modify the throttle cable to get it to work. Quad ran great at 1/4 throttle, but anything above that and the throttle would stick and the machine would run like garbage again.
What I know and think: I hear carb issues are common and fairly easy to fix. Also, I think they used the 'universal' rebuild kit that claims '88-'11, but the jets and such were different from '00-'03 (gaskets, etc. appear to be the same) so their original attempt was a good idea, just not good enough.
They did give me the original carburetor with the 4-wheeler, but it has the wrong internals. I'm thinking if I can get the right jets, springs, etc for the rebuild, I should be able to get this thing running right. Of course, I still need to charge the battery back up, change all the fluids, replace fuel lines, plug and wire.. ya know, the basics for a machine that's been sitting for roughly 9 months. lol
Just joined up with premium membership. I wish to download a service manual or 2 (specifically the Polaris 110 EFI manual). I paid for the membership, but when I try to download it says it's not available to me. I know I haven't posted anything until now, but I thought the premium membership gave instant access to downloads. Not sure what I'm doing wrong?

Just bought (Tue. evening) an '89 Suzuki 250 4wd that has been sitting out the last 5 yrs. It's complete, including the shift knobs, battery cover, and headlights. It has the optional cooling fan on it (probly stuck - didn't check), and the engine isn't locked up. Plastic looks good and isnt cracked. Racks aren't bent up. Shift lever works, the foot brake moves (needs oil - have to pull it up by hand), and there's black oil and no water in the engine sight glass. Guy was asking $125 and gladly took $100 for it. Anxious to get started on bringing it back to life. Been wanting one of these for years. As soon as I can get to it (working on a junky "Jackel" right now - Chinese Yamaha Timberwolf). I'm going to pull the tank off it and clean it, clean & possibly rebuild carb, put in new plug, and a battery, then see what happens. If nothing, will keep going until it runs. Feel free to respond if you want to, I'm mainly just excited and wanted to tell somebody.
I just bought two 1985 TRX250's from my father-in-law. One runs great, the other not so much. The one is having issues with the shifter. The shifter seems to be resting lower than normal. When I press the shifter downward, it just pops back up. Any thougjts as to what the issue might be?

i just rebuilt the top end of a 99 Bear Tracker 250 and it can’t get it to hit off of gasoline or starter fluid. Occasionally it will backfire. Right now I’m just trying to get it to fire off without the carburetor like I’ve done a thousand times before with other engines. Usually there is no response, but occasionally I get a backfire through the intake. ISeems like it’s out of time, but I don’t see how that could be possible.
Here’s what I know:
1. compression 120psi
2. all timing marks are lined up after numerous revolutions.
3. Strong spark.
4. Valves adjusted correctly.
Thanks in advance.
