HELP! RYCA won’t idle. GYROBOBS RYCA
12/12/24 at 15:10:35

Hello! My name is Pierce! My family friend, Robert has passed. (Went by Gyrobob on the forum) I bought his bike from his wife to help out with the adjustments. He let the bike sit for a while so I had to clean it internally completely. I understand the RYCA setup great, I have the other RYCA bob had build in his (Double RYCA Build) posted in the forums. I Got it to fire up but won’t idle good at all. I’ve cleaned the carb 5 times and checked for pinholes in the diaphragms. Checked spark, spark plug, clean gas, clean tank, new petcock, new battery, check voltage with load, starting fluid, Robert had the bike running GREAT! The carbs DO NOT need to be rejetted. He was a mastermind and so smart. Check out his old profile (Gyrobob). I added a link to a video so you can get a better idea since it’s in depth. But please help. I want to see the his wife smile from the bike, one time at least…

You don't have the choke pulled?

Don't let it idle on the sidestand. The cam doesn't get oiled right.

The idle speed adjustment might be set too low.

Welcome to The Asylum!

Step across it, stand it up in Neutral.
Fire it up.
Using the throttle, does it run okay if you keep the rpm up,like an easy cruise down the road?
How low can you get it before it quits?
I forget the minimum safe rpm. It's gotta be ticking along good enough to make ten or so mph.

When the choke is pulled, the bike has a harder time starting for some reason. It backfires through the carb really bad as well when I pull the choke.

The bike is strapped perfectly straight up to a trailer for the mean time I’ll take it off tomorrow and see what kind of riding I can do on it before it dies.

If I give it throttle sometimes it revs perfectly and returns back to idle. Other times my throttle seems to kill it. And this is in the same session of trying to get it to idle

Idle for the Suzuki savage is 1,100RPM
I can get it there but it won’t last long until is snuffs out

Maybe dirt in the bowl? but you cleaned the carb... tough one.

Is it a stock carb?

I'm heading over to my RYCA buddy's place tomorrow to replace his carb with a new VM 38.

The verslagen! Thank you for your condolences.
Yeah the VM38 bike I don’t know who’s that was, but Jud (uncle) had the other RYCA I manage to buy. He had a VM36 that was severely jetted wrong, I rejetted the bike and it was a great bike until it got stolen and almost ruined. A lot of work needs to be done to clean up that RYCA.
I cleaned the VM36 I had on the one RYCA and threw it on GYROBOBs bike and it did the same thing as the stock carb.

Stock carb on it now.

Cleaned the filter with filter cleaner and sprayed the oil as needed.

Valves??

Thank you for taking time to reply and think about what could be the issue, been on the forum for a while reading all of y’alls information and it’s been so helpful.

You changed carburetors and the problem stayed the same?

"You changed carburetors and the problem stayed the same?"

Intake manifold leak maybe. Check the rubber dealey that the carb plugs in to on the head for cracks or if it's gotten rock hard from age and wont seal even if the clamp is tight.

If you can get the bike to idle at all for a little while try spraying some carb cleaner or brakeclean around the joint. If the idle goes up or down while you're spraying you've got a leak there.

Sorry to hear about Bob's passing.

1. Stop twisting the throttle when you engage the starter. These are not pumper carbs. The carb is designed to provide proper fueling for starting with a closed throttle.

2. When you say you "cleaned the carb" 5 times, does that include replacing the jets at least once? Brass is cheap, throw the clogged jets in the trash and get genuine replacements.

R.I.P. Bob , Pierce may be time to open engine , I would want to inspect cam chain on right and stator on the left. Carb & petcock don’t seem to be issue. Usually ignition controller either works or not but I would try another before opening engine. You need to try a spark tester to see if it’s not sparking when it’s not starting. Loose pickup at stator , crushed wiring or loose corroded connections. Do not give up , it’s a process of elimination and your almost there !

GYROBOBS RYCA Reply #11 - 12/13/24 at 10:10:11 If you check spark with the plug out it can lie to you. Under compression the starter eats power. Pull the plug, it might spark. Put it in, no spark.

Gonna order some parts like the jet and new spark plug. Gonna check out the possible leak. And yes sir Mr.JOG same symptoms different carb. So just by using the ol’ noggin we can deduce that the carb is likely not the problem in this case.

I had typed

And you're still looking at the carburetor?
But deleted that. It sounded snotty when I read it.
