sorry just wanted to make sure I was staying on your list and was doing things right. About to throw some oil in it, throw another ground to chassis just in case, and than check for spark. I’ll report back in a little bit.

@QuadManiac so did thee mentioned above. Put the plug to the header and cranked and sure enough I have spark. So I cranked again, yes spark but counted to 5 this time let go. Stayed consistent with a little mini lightning storm. Shut it off. Got a drink came back. Cranked again, spark yes counted to 5 stayed consistently on.

it’s a little late to try and start I’ll keep you posted in the morning. I appreciate all the help, lessons, and patience through out this learning process.

Great! Now on to fuel... and starting fluid, IF necessary.

Did you determine WHY you had no spark?

verified your list. When I went to check for spark it was gone. Changed the stator and so far the two times I’ve cranked it’s had a nice white spark. Going to put the boots, filter back on and mount the tank since the carb was still on. Let you know in the a.m.

I have to go to work. But I had everything together from last night. Turned on the petcock and went to start. Have a little cough after like 3 turns, I stopped. Started again and cranked right up. Opened up the idle screw a little to level it out and took it for a ride. Thank you so much for helping bring it back to life.

has some popping but I’ll get the tuning done another day have to go to the good ole job.

So warmed her up yesterday and choke seems to work as I needed to use it to warm up. I had a slight hesitation so to work that out. If it’s from start to 1/4 it’s the idle screw, 1/4 to 3/4 is the low carb, and than 3/4 to full throttle is high carb.

right now I have the k&n without a lid. I was getting popping at idle so I turned the screw out a bit. How do you know when it’s just right?


Is my adjusting based on me revving at idle and making sure it revs straight through? If I hit a problem I adjust that circuit?

There is no 'low carb' and 'high carb'. They both contribute almost equally across all throttle positions and RPMs. The left intake port in the head is just a bit smaller so, at high throttle, it flows a bit less so the left main jet is one step smaller... that's it. The only reason the Raptor has two carbs is because a single carb would have made the engine stack-up too tall to fit.

SO
Off to 1/4 throttle is the pilot jets and fuel screws;
1/4 to 3/4 is the needles;
3/4 to wide open is the mains.

If you're going to run with a lid, test with a lid. You are too lean without it and your adjustments are worthless... If you're going to run without the lid, then jet and test accordingly, with it off.

Friend came over tuned it for me took it for a spin, has nice acceleration and some pops on decel, which I believe you said was from lid being off.

only issue is a oil leaking from bottom line. I know the banjo bolt is m10x1.25. I read on here you can put a longer one in. Any info on that? So obviously change the crush washers which I never did like a dummy. But I’m pretty sure the threads aren’t to strong in their right now as didn’t feel to strong when I went to tighten. So thought the longer bolt would be a piece of mind.

Not what I said... re-read it. I said, to greatly expand, if you plan on riding with lid on. TEST with lid on... if you set jetting, as your friend has, with lid off, ALL will be wrong with lid on.

We're getting back to that inability to follow instruction again... page 11 coming!!!

Maybe I wrote it wrong. Because definitely riding without the lid. And was setup without the lid. Accelerates straight through. Get an occasional pop on decel. And one carb is dripping a bit. Other than that she’s running great! Took up the street got it into third and slowed down didn’t wanna piss off the locals. I never replaced the seats and needles just used the ones from old carb. Are those generic Carb rebuild kits ok to use?

Open your fuel screws 1/4 turn each for the popping on decel.

Get a decent parts house rebuild kit not eBay generic.

@QuadManiac so bought the rebuild kit For the carb changed seats and , set the floats, turned the fuel screws up a 1/4 on both as you suggested. Rev is straight through at idle. I have a soft constant pop not like when it’s back firing, would that be from the spark arrestor being on?
The 1/4 turned definitely stopped the decel popping, think I heard a pop maybe once while riding it up and down the hill but I assumed it to be the carb recovering from me on and offing it.
Before it was sluggish In some of the gears but holy cow now she pulls like crazy. I felt a pinch bog in like 3rd around 3/4 but I couldn’t repeat it.

I have a drip of gas from the right side but I think it’s just coming from the picture I included, I don’t have a hose connected to it.
Cause I just changed the seals on the bowls so I doubt it’s there but I can’t See if it’s coming from the mating surfaces or just sliding down from the drain.

Thank you for all the help! From everyone it is greatly appreciated!

@QuadManiac so was looking into the little gas leak. Seems to be coming from the mating surfaces on the right carb. Ever had an issue changing the orings for the bowls and still didn’t seal right?

Read on another thread could be feed pipe orings causing it to look like the bowls are leaking. Any insight to where this is located?

Pretty sure it was one of my bowls was cracked. When I flipped it upside down I saw it and was like wtf. Crack was inside as well. Swapped bowls with the old one and so far so good.
