I have a ( looks new) carb. If u want $50.00. My problem was wire. Don't need.?

Personally, I would do a couple rebuild. I only did rist pin up. Running prefix. Mine had Low mileage. + A complete wire harness exchange. ( hacked) . 1998 450es now runs like New!

Mi 98 450es are 12. Love these. Aggressive

All my work was done with the engine in. I would pull the tank then you can remove the top end. See why yours locked up. If you need to remove the F cover, get a cherry picker to lift the front up.

Cam tensioner failed. So to replace, the whole topend has to come off. So new oil pump (good luck finding one) cam tensioner,chain,guides, ristpin,piston,rings,cylinder. Did a leak test on valves. All good. New carb (didn't need). All OEM parts. Carolina cycle was the cheapest. + a New complete wire harness. P.O. had hacked most of it.

Running like a top! Start's on command.

Check out Carolina Cycle, I too came across a 98 450es with a lot of new parts (externally) at a good price. but the motor was extremely loud! (internally). ran strong, not smoking. undergoing a slow tear down, I discovered a bad cam chain tensioner, bad chain. So, to replace the tensioner & chain, (the top end has to come off). bike had only 2535 miles on it, why did it fail? suspect an oil pump failure. (Good luck finding one in the USA) I found two - one in TN, one in CA. or rebuild what you have. Long story short, why not go back to all stock OEM parts. Carolina Cycle was the cheapest OEM parts I could find (Partszilla was overpriced) in my opinion. So, I put a new cylinder, rings, piston & wrist pin in. All stock OEM parts! Bike runs Great, Starts on command. 450 is probably more power than I need, But why not! LOL Good luck on your rebuild.

Hi, the by-pass works well. But on mine (98) the gear read out dosen't display 2,3,or 4th. Easy to install. Go to Hondaesbypass.com. I believe.

Thanks guy's, both are on there way.

Hay Fishfiles, temp light does come on temporarily, ( I'm like a kid in a candy store - don't see the container just the candy) lol. I did what AKATV said. ground the blue wire above the RR tire, and the fan comes on. I checked the sub harness on the thermo sensor and it has continuity. I bet the sensor is bad. If I have to go thru all the trouble to remove it, ( drop the skid plate) I might as well replace it and the sub harness also, harness looks in bad shape. I installed the shift by-pass unit and it shifts with the buttons now. I believe the change switch is also bad. speedometer sensor assy. seems to be ok as it shows speed on the meter. Hopefully this is the last thing the bike needs to work as originally designed. living here in Michigan i'm also on the hunt for a snowplow. Additional comments welcome. Thanks for all your guys's Help!!!

Thanks AKATV, I have a manual. I put 12vdc to the fan and it works. high temp light only came on once - when I first put oil / oil pump in.( that was with the old wire harness.) I haven't seen the light since. should the light come on every time when the key is turned on? What are your concerns about the by-pass system? ( that hasn't come yet). I can't get back to the bike till this weekend. then I will start checking for what you referred to. I don't like the looks of the wires going to the reverse switch ether. I will be able to see more once I get it back up in the air. Thanks for your input, get back with you then.

Gentleman I got an update! Installed a new wire harness (pain in the __) we now have a quad that will rev up!!!!. I still have issues, lol Fan doesn't come on, reverse light flickers, unless it's in reverse. then its bright. neutral light is always on. gear indicator only reads R, N, 1, and 5. es system not working . waiting on my by-pass unit to come. But hay its Useable. P.S. motor runs Great! - no clanging and banging. Thanks for all your help! Much Appreciated.

No I'm going back to the es. Like it was.

Thanks. I can see right now y my fan doesn't work. The green wire to the carb heater is burnt. Noticed that when I replaced the carb.

Hay Fishfiles, Jeepwm69 - the reverse light is always on. I couldn't see what the meter said until Akatv fixed me up. Now the meter shows what gear i'm in. neutral light works now ( Akatv fixed that). but even with the reverse light always on, the bike ran great ( - the terrible engine noise) . I just got a message that the new wire harness will be here sat. let me hit you guys up when I get that done. we can go from there if you will. Thanks!
