So I can use that iridium with no issues?

Thanks.

I put the DR8EIX plugs in about 3 months ago. They work fine. I can't say I noticed any difference, but given what a pain in the butt it is to replace them, I'm glad I won't need to for a long time. I did a quick writeup, but didn't take pics: http://advrider.com/forums/showpost....postcount=4095

Thanks Marc. I ordered 4 of the copper cored ones but I'll pick up 2 iridiums.

I bought an xchallenge recently and the rear plastic white part that goes form the seat to the rear light has some cracks in it. It seemed like a repair was attempted with epoxy / fiberglass but did not work. The part is made of something else then fiberglass. Anybody know what works with this plastic for repairs?

Is the plastic actually cracked all the way through, or is it just the white paint/coating over the plastic. Mine has several chips and cracks, but the plastic part itself is still intact. I've just left it alone. I'd probably just dump it again after I painted it.

The plastic itself is cracked in 3 places due some abuse (fun).

I can't imagine any repair to the plastic that would hold up. My guess would be just replace the piece. I'm sure bmw doesn't charge much for that rear piece..
All three of my plastic pieces are pretty banged up. Both fronts along with the rear.. I've just been putting stickers over the chips in the white paint. Maybe I'll replace them if I ever sell the bike..
"Never dropped" "Like new" ha..

new one is "only" $223. I will have to start experimenting.

not sure exactly what type of plastic the fairing is but if it is ABS then you can weld it back together - you can buy ABS welding rods and then use a decent soldering iron to weld them back together - have done it on my old bike. there's also a chemical welding method but can't recall which chemicals you need...

for the plastic welding you basically file the cracks to make a nice groove (the ABS rods should be a triangular cross-section) until the rods sit in them nicely, then apply the soldering iron to melt it all together... takes a bit of practice but i dropped my old super tenere on the welds plenty of time and they didn't crack again....

Xmoto. ~55k km.

I too have the warm start problem (where it will crank over forever but never fire after filling up with fuel). I've had it intermittently since getting the bike, but it seems to be worst when it's raining - I seem to always be stuck at a fuel station in the rain.

If the bike is hot and not stopped for too long then it's fine. If the bike is cold then it's fine. It seems that the time it takes to fill up and pay for fuel is the sweet spot for making it fail.

The other day I had it fail on me, and after cranking for a few minutes I decided to roll start it. I rolled it down a large hill, in third, and the engine was rotating at a decent speed for probably 10 seconds total - and not one fire. After pushing it back to the top of the hill it magically started again.

The sticking injector theory is interesting. I might try a bottle of injector cleaner followed by the 2-stroke oil idea and see how it goes (I already have a new set of plugs waiting for when they get fouled).

I'm also going to be more diligent with putting it on the trickle charger overnight (although I do ride it 5+ days a week) in a pretty warm environment.

I'm certainly less than impressed with the reliability from a ~BMW~ (it seems to be more aprilia than bmw)

Having an issue. Changed the plugs among other things (non engine related) and after putting it all back together it cranks but won't fire. Fuses all good and everything looks right. Have to check spark and see if they are both firing. Didn't touch the fuel system at all so that should be good. Did all the usual stuff, side stand switch, clutch lever, etc... I'm stumped at this point. I think I'll pull the plugs and do it all over in case I missed something. I know I have the two coils right.

These bikes are incredibly sensitive to voltage from what I've discovered. If the battery isn't great then the cranking voltage will cause them not to fire - otherwise known as the G650 hot start issue. Check your battery.

Did you unplug the sensor on the air box and not get it fully seated when reassembling?

Battery was on a tender the whole time the bike was apart but I'll check it. Thanks.

I'll check it to make sure. Thank you.
