Fz is 2 speed, carb different as well as other engine parts.

Would anyone happen to have a FA50 kickstart spring guide that they'd be willing to part with? They seem to be unobtanium anymore.

SUZUKI FA50 FZ50 KICK SHAFT SPRING GUIDE 26221-02301

There’s one on eBay for like 20 bucks plus shipping

Never created a link before…like this???

Kickstart cover

Thank you everyone, I got one ordered. Lots of other parts coming my way as well so I'll begin work soon.

More pics

There is only the thinnest amount of friction material left on the clutch.

I need to replace the clutch but it looks like the bell is ok.

The bell looks like it has been pretty hot and is discolored but I'm not sure if this is a normal thing.

Any thoughts or advice based on these pictures would be greatly appreciated!

Cheers

I'm getting there with my Shuttle. I have replaced SO many parts and my current holdup is getting spark. After discovering I wasn't, I tested all electrical components per the FSM and the CDI and coil both tested bad. I have parts coming from eBay and I hope to get them swapped out in the next few days.

I do have a question on jetting...this is my setup.

60cc kit and stock clone carb from Treats

MLM next level stock pipe

no porting

stock intake and reeds

Does an 82 main jet sound like the right size for this? That gives me a 6% increase. I will get some pics up soon to show where I'm at.

I got my used CDI and coil and now I have good spark but I still can't get it to start or run. These are the things I have checked:

Timing- the mark on the stator and the flywheel both line up perfectly with the mark on the case at TDC. I haven't hooked up a timing light but I think this should be a good starting point. Removed both coils on the stator, cleaned the mounting surfaces, and used a little dielectric grease to prevent future corrosion.

Fuel supply- I'm getting good flow through the petcock and can see the fuel moving when I go to Prime to fill the bowl. All of the fuel supply lines are new.

Air- I have the stock air filter setup with all new parts. There is no change with filter installed or removed.

Compression- I have a new 60cc kit from treats. Ring gap and orientation are good, head and cylinder gaskets are new, head nuts are torqued to 90 inch/lbs. I used my regular automotive compression tester and only got 40 psi, but it has a 14 inch rubber hose so I don't think that really tells me anything.

Spark plug- It is sparking and I occasionally get a pop when I'm kicking it. It is a new NGK BP4H plug with FSM gap. It smells of fuel when I pull it out but doesn't have any obvious signs of combustion going on.

Carb- New 12mm clone carb from treats. I disassembled and cleaned out a few flakes of metal that were in there. Set float height to spec and installed a new 82 main jet and 20 idle jet. Also set the mixture screw to 1.75 turns out per the book. Throttle and choke both operate smoothly.

Crankcase- I got a new conn rod and bearings pressed on and have new viton crank bearing seals (along with all the other seals on the bike). I sealed the 2 halves of the crankcase with HondaBond.

Exhaust- New MLM next level stock pipe with new gasket.

Intake- I looked at the reeds and they seem to be working as they should. As far as I can tell they close tightly and don't have any chips or anything. The molded rubber gasket where the intake joins to the crankcase looks fine. Should this have sealant?

I tried squirting some fuel into the spark plug hole and then cranking but it still didn't fire at all. I've been through Fred's guide several times and I think I have considered all of the options. I really don't know where to go from here. Anyone have any ideas? Thanks!

Is there a Schrader valve at the end that goes in the spark plug hole?

Mine has one with a long hose and I get perfect compression readings of 145 on my QT50.

With the pipe and kit I'm saying your jetting needs to be richer.

I was surprised with how much bigger my main needed to be.

I have jets from 70 to 130. 70 was stock and now I'm at 115.

I got it running. When I was installing the stator there was a notch in the edge near one of the screw holes so I used it as the point to put next to the timing marks. Timing seemed screwy though so I took the stator back off and searched for other marks. Ended up finding the proper mark under one of the screws...I couldn't see it before due to surface corrosion. I installed it properly and she started on the first kick!

Here's how she looks after getting everything back together

That’s great. Glad to hear that you got it running. Looking good.

Just try the clip one way . If it runs worse , you know to go the other way .

I removed the air filter foam and it allowed maybe a tiny bit more throttle before the four stroking starts. Since leaning the mixture a little bit seemed to help my next step will be to move down from a 100 to an 88 main jet.

Does the needle affect the last little bit of throttle travel? If so, maybe I should lean it a bit also?

I'm looking at a temp gauge that loops around the spark plug

Amazon Temp/Tach

Does this look like a good one for tuning?

Cheers

Alex

What temps should I see at the spark plug with extended WOT runs? What about RPM?

I'm currently getting 335 F and 12,900 RPM as the peak numbers. It still loses power and stumbles with too much throttle but I'm able to get up to mid-20s on the GPS.

Does that temp indicate that I'm running lean?

Thanks!
