SuzukiSavage.com - Engine does not start

zevenenergie Serious Thumper Offline SuzukiSavage.com Rocks! Posts: 1241 The Netherlands Den Haag	Engine does not start 12/04/20 at 07:09:55 Now that it is getting colder my engine starts worse and worse. Today 42.80 ℉ after 2 weeks of not driving, it didn't start at all. It has a new battery. Which I am now charging, because I started it almost empty. I have a 155 jet, would it help to get it starting better? Does anyone have tips.?

Only the pilot jet and the choke have any effect. Are you using the choke? You don't mention it. By the way, 42* F is not very cold.

If you flooded the engine, chances are you fouled the spark plug. You will need to remove and clean the plug.

Also worth mentioning that our carbs to not have an accelerator pump. Opening and closing the throttle during a start introduces more AIR into the mixture - making the bike harder to start.

The FCR carb on my DRZ has an accelerator pump. If I crack the throttle on that thing its like watching a camel spit.

I would try external things to make it richer before digging into the carburetor. Try these one at a time.
Open pilot screw 4 turns.
Block air box opening 1/2 with cardboard/duct tape.
3/4.
7/8.
If any of the above make it easer to start, install a larger pilot jet.

Also, don't overlook grounding. I had a DR650 that was a bear to start when cold. Cleaning the engine to frame grounding cable connections solved the problem.

I installed the charged battery and then tried to start with the trottle closed. No starto......

Then I took te sparkplug out, and found that it was loose and half way turned out. Tongue

Placed a new one, and the engine started right away. Cheesy

I am happy with my new starting skills.
And would like to thank you all very much for your help. Tank you Kiss
