Lmao nice Cunningham! Only problem I'm having now which I haven't had since I first finished this build.... The **** bike won't start! I've pulled the carb and pipe back off I pulled the reeds out and put everything back together sealed up tighter than a Dolphins ass, got spark, got fuel but won't start! We pull started it at my buddies and it was lean which is why I pulled everything apart and resealed everything. The damn bike ran like a top before pulling the old swinger started first kick almost everytime would set for two weeks come out few primer kicks and bam fire right up. I'm beyond frustrated again.

Gonna pull the flywheel and check that crank case seal. At this point it's the only thing I can think of but makes no sense we pull started it and it ran was lean and leaking air somewhere it would still fire up on one kick after being pull started I fired it up 4 times then rode it into the bed of my truck the very next day it wouldn't even fire up. If the crank case seal is leaking doesn't make sense why it would start 4 times in a row first kick and now not fire at all unless it was leaking and that last time it fired up it came all the way out or started leaking even more than before.

So the bike will fire up if pull started then will fire up one kick every time once it's started. Runs like a top once it's pull started let it sit over night last night and wouldn't fire up this morning. Humidity was 97% in my garage and my pilot is fat so going to drop my pilot from 42.5 to 35 and see if that's the issue. Still going to pull the flywheel just to check that seal. Just weird that once pull started it runs like normal and starts one kick no problem like usual.

man, that's a massive pilot. Is your carb slide worn?

ZillaFreak · « **Reply #904 on:** July 20, 2015, 06:33:36 am »

Before just aimless checking parts for leaks, do a leak down test. 10x easier to know if you have a leak and find it than just randomly guessing.

If it is running good, then the next day it is ****, might be getting water i the gas. The weather around here is **** and it is extremely high humidity.

Q2W that's my winter pilot so it fires up in 20* weather and the slide seems ok filter side is still completely black and reed side is mostly black and with the carb off I can't see any light getting around.

And yes Nick I agree going to finally break down and build me a leak down tester lol.

Thing that baffles me is before the swing arm swap the bike fired up one kick even on 95* days. And now won't start at all.

ZillaFreak · « **Reply #907 on:** July 20, 2015, 09:00:57 am »

Might want to check to make sure you have a good ground.

IIRC, the swingarm bolt goes through the engine, you might have made the engine to frame ground bad or something. Worth looking over the harness and all grounds.

I am wondering if humidity is effecting it?
The average humidity for the past week in Amelia was 94.8%. Most of the time is was 99%.

Buckeye513 · « **Reply #909 on:** July 20, 2015, 09:37:38 am »

I'm thinking humidity as well is a big factor I'm going to run a ground strap from the front frame motor mount to one of the engine bolts to rule that out. The old swinger was bare metal the new one has about 15 coats of paint on it lol.

I kinda had the same issue the other day when i went to the dunes. I could not get my bike to start on the first kick. Had to kick it 2 to 3 times. Was annoying. $:-\$

Buckeye513 · « **Reply #911 on:** July 21, 2015, 12:04:06 pm »

Yeah annoying as hell cause all my buddies call it mr reliable cause it's the most reliable bike of the bunch lol always a one kick starter.

Buckeye513 · « **Reply #912 on:** July 22, 2015, 04:57:48 am »

Put my 35 pilot in and fires up in one kick. Weird but I guess the extremely high humidity was the culprit

Yea, my bike was the only one to survive the last dune trip. I think the motor is getting a little tired and it's time for a rebuild.

Well the bike is dieseling at idle and won't stay idling. Leak down test here I come! Damn bike was perfect before the swinger swap so this just doesn't make sense!!!

Have you tried draining the fuel tank and putting some fresh fuel in it?

Buckeye513 · « **Reply #916 on:** July 28, 2015, 05:15:39 pm »

I have not drained the fuel. I just put the fuel in and went trail riding the weekend before doing my swinger swap.

You may have some water in the fuel or the fuel and oil separated. The water and oil go to the bottom of the float bowl....They are difficult to start when trying to run on water or pure oil.

Buckeye513 · « **Reply #918 on:** July 29, 2015, 06:13:19 am »

Not a bad idea cause I run mine thick at 25:1. Gonna try bumping my pilot up a little because when it wouldn't kick start and would start with a pull it idled fine and would start one kick after being pulled.

Buckeye513 · « **Reply #919 on:** July 30, 2015, 02:10:22 pm »

Well here's a video of it running anyone have any input?

Buckeye513 · « **Reply #920 on:** October 27, 2016, 10:28:02 am »

Damn been a while since I looked at this thread. My 500 is sitting in pieces and I've had two little girls since having the issues with it last year. It's waiting for me to have time and money to throw at it again. Bought a banshee as well and locked the motor up on it from what I don't know haven't **** it open pretty sure it just hung a ring.

Longest running thread in the forums history I believe!

Darji has that crown. wasnt it in the 100's?

Stpltn250r · « **Reply #923 on:** October 31, 2016, 12:09:12 pm »

Probably, but it was just a bunch of pictures with what I assume was the aftermath of a beaver nawing at his ports

Stpltn250r · « **Reply #924 on:** October 31, 2016, 12:09:58 pm »

Also video of it running and doing donuts with no air filter on in the desert
