Cold Start stalling

Sigh

Today to take out my old TPS. Use a T25 torx wrench and was unable to open. Not sure is because screw seizure or what.

In the end I slip and the torque wrench dropped. I can't find the wrench. Think I need to open up the fairing and find it :(
 
You're not having a good week are ya Daf. I lost a screw, inside a yoshimura can the other month, between the outer skin and the baffles. I was sure that one was gone forever but by a miracle I was able to snag it from the "outside" with a magnet and drag it up to the hole I lost it down and extract it :D
The can was SS and screw obviously plain steel, couldn't have rescued it any other way I recon.
 
Help help help

I am getting depress

TPS replaced and sympton persist. Everything remain the same.

Every sympton brought me back to ISC valve which I had replaced.

I had call the shop that replace my ISC valve as I know it needs to relearn the position (and that's the reason I went to a shop instead of replacing it myself.)

The shop told me they using China 3rd party software to adjust the rpm only. They are not sure does this reset the ISC valve position. They only had the option to input desire idle rpm.

Is this the reason of the persist sympton?

Anyone know how can I do this or should I just bring my bike down to suzuki authorize distributor to ask for a software adjustment?

Because on the phone with suzuki, they say a software reset cost usd$150. I am thinking to buy the Sds tools myself or better still upgrade to woodlich.

The only thing that made me feel great today...

Yes, that needs to be reset properly with SDS.
Did you ride it?
Is the clutch switch at the lever sticking?

I did ride the bike for about 1000miles after the isc valve replacement.

I did not ride the bike after the TPS replacement

Clutch lever is not sticking, I did read about the clutch switch thingy before when I was reading the isc issue. For elimination purpose. I will replace the clutch switch.

The sds tool 09904–41010 I manage to find on aliexpress sold by China. But the software only support til windows 7 and base on the list says support til busa L2.

Any idea the supercede version of the sds tools and software?

If the clutch switch is functioning normally, I would not replace it.
I would let the dealer reset the ISC, before I gambled on buying an SDS that may not work.
 
Dear all,

Suzuki authorized service center send me this.

I am lost for the word.

Average compression is 40psi while chamber 3 has 0 psi... I remb the average compression should be 180 right?

I don't understand if this compression pressure is real, how did I manage to get my bike to 180miles per hour...

Is this a hoax? What are my options?

That bike wouldn't run at all with compression that low......

No way that engine suddenly lost compression across all cylinders without blowing a head gasket, which would have a very noticeable coolant and/or oil leak, internally or externally.
They aren't doing the compression test correctly.

Sigh

I decide to give up on the Suzuki Ad and brought a healtec Obd s01

Next after that I will try to read understand the manual and plan for a valve clearance check.

If pressure still weak then I will I have no choice to send back to overhaul at Suzuki Ad.

Wish me luck...

Valve clearance isn't the problem either.
If you have several out of spec tight valves, you can get hard starts/longer time to crank, especially when the engine is hot, but it's not a big deal.
At 44k miles I wouldn't be suprised if all 16 valves were still in spec either.
They also aren't the cause of that strange compression reading...your bike wouldn't even start, let alone run, if it compression that low, and you would have a mechanical failure, an/or oil or coolant leaking internally and/or externally from a blown head gasket.

Did they not reset the ISC while it was there? As that seems to be the most logical answer at this point.
Can the Heal-Tech you ordered do that?
