DR650 spark plugs
« on: March 10, 2015, 10:32:46 am »
As i tend to do with every bike I purchase I go through it slowly and methodically, looking for good and bad points, servicing, fixing, etc.

I previously noticed that the fuel petcock drips slightly when one changes the setting - so a rebuild thereof with new seals is on the cards.

When I lifted the tank I was, therefore not surprised to see fuel and dirt deposits on the cylinder hear below the petcock. Took of the leads and spent the next few minutes fishing out small pieces of stone stuck around the bottom of the inner sparkplug and brushing the area around them clean before removing them. Blocked the holes to ensure not infress of foreign matter and then had a closer look at the spark plugs themselves.

The inner of the two had some hard baked dirt / rust deposits around its base whilst the outer one was in much better nick. The plugs looked in good nick otherwise, with slightly black tips.

Bike at that stage ran a K&N filter (now removed), standard airbox, slightly gutted OEM pipe and (as yet) unknown jets.

Problem is that these are NGK CR8E whilst the standard plug is sopposed top be a NGK CR10E with a NGK CR9E listed as a hotter alternative.

That suggest that these plugs have too hot a rating. Although there was no signs of blistering or overheating I do not feel comfortable with leaving them in.

So what plugs do you guys run? I see there is also a twinspark EK variant available. Is that a worthwile consideration?

Any comments or advice would be appreciated.

I could agree with you! But then we both would be wrong.....

O ja, moet by se dat ek nie die Dakkie verkoop het nie. Hy is my klein toerfiets. Het juis die naweek n rit in die Sabie/graskop/pelgrimsrus area met hom gaan ry.

Dakar het n hoŽr cruisingspoed.
DR's en XT's voel net nie gemaklik teen 120 op teer. Of vir my in elk geval. 110 ia hulle fine heeldag lank
maar teen 120 klink hulle asof die engine skree.

Nou waar is al die DR fundi's?

Als wat ek tot dusver op die net gesien het dui daarop dat die CR8E te warm is.

Hier's 'n kiekie van die plugs wat uit my DRs kom, en die boksie van wat ek huidiglik gebruik. Carb is 150 main, 45 pilot en 3/5 naald. Plug kleur is ligbruin.😉
 
Myne loop soos 'n jet met vol after-burner. Vra my KTM maters!👍

So jou DR(s) het voorheen n kombinasie CR8E en CR10E gehardloop en jy het dit nou beide vervang met CR10E.

Ek gaan definitief die CR8E uithaal en vervang met CR10E's.

Use CR10E

If you can't get CR10E use CR10EK (twin ground electrode type, no real advantage, supposed to last longer, costs more).

The CR10E's are sometimes difficult to get. CR10EK should be available from your friendly BMW Motorrad agent :mwink:

CR9E only in cold conditions (as in Arctic)

Definitely no CR8E's unless maybe if you ride around on Mars at night ???

Thanks, I wonder how long the PO was riding with them in and what made him fit it?

They are coming out today as I have managed to buy two new CR10E's at Suzuki Motorcycle Mecca for the very reasonable price of R72.81 each.

I guess I got lucky because they seem to be somewhat hard to get.

For those Pretoria guys looking at CR9E's, Silverton Midas sells them at R63.00 each.

Kom uit 2 verskillende DRs. Net een van elk in die foto gesit. Was bietjie laat al gisteraand! CR10E is reg.👍

I have 2 of these bolts to blank off the spark plug holes, when cleaning the engine with the plugs removed.

Blanking off with those bots is a good idea as it is very difficult to clean around the base of the sparkplugs with them still inserted to ensure that nothing drops into the cylinder :thumleft:

Why not use compressed air and just blow around the plug after cleaning ?

With baked-on dirth one needs to clean there with a paintbrush and some petrol and then Prepsol. Some of us are a pain in the but when it comes to the cleanliness of our bikes.😉

The compressed air will help a lot to get rid of any loose dirt, before removing the plug.👍
