KLE running problem
 

Hello Mutha.

My KLE has the exact same problem as you described above in #1 after you had it serviced. Funny this happened to me after I serviced the bike as well. Changed oil and filter, changed plugs and cleaned and reoiled airfilter.
Any chance you can ask the workshop what they did to get your bike running properly?

I was supplied by the bike shop with D8EA NGK plugs. Unfortunately I did not look at the numbers on the original ones. I dont know if this is a problem, as the manual specs a D9ea

Regards

At KLE 400 is D8EA not D9EA:biggrin3: , mine were D8EA and I let them D8EA
Also you can look in a NGK catalog to see that for KLE 400 is 8EA

KLE plugs
 

Hello Kumuya.

I changed to 9ea, and now the bike is back to running fine. thanks for all the input and help. You can check the tech thread you started for some more details on the fix.

Are there anyone out there with another KLE 400. I would like to know, as I might have a wrong fuel mixture / timing setting, that is forcing me to use the 9ea. What are you guys running, and what are your summer temps?

regards

Glad you got the problem fixed. The way you described it, it sounded like an ignition problem, but I didn't even think of the plugs!

Most of the experienced off-roaders will tell you you need the correct plugs and oil for the temperature range you're working in if you want a smooth running engine, regardless of catalogues. Many manuals have errors in them anyway. Does anybody yet know the correct front tyre pressure? Everyone I speak to says something different, yet the manual says 22psi.

Tyre pressure
 

Hello Mutha.

If you look at the weight of the bike, and the 21" wheel in front, I would think 1.8 bar (do not know psi) should be good. On gravel roads I run at 1.2, and offroad 1 bar front and back.

It all depends on the speed and available traction. Too soft at high speed, and the tyre will fold in under the rim. (no fun) Too hard with little traction and the front goes sideways without you. (No fun either)

If you look at how your tyre wears, you should see if you are running the correct pressure for daily use. If it only wears in the centre, then too hard. If it only wears on the sides, then too soft.(unless you take corners like SBK) Unfortunately you only find out about the wrong wear pattern after the tyres has worn.

Maybe Le Cap can help, as he has quite a few KLRs with the same wheel sizes.

hope that helps
