    That's all homebrew. I assume the little box behind the "battery" is some kind of rectifier. In addition to the output for the CDI the S stator has three yellow wires for charging output (3 phase AC). The off-road stator has only two (single phase AC). Bet those are capacitors in that "battery". That's how I run my kickstart S model. No battery... Just some big caps.

    My DR has a slight puff of smoke on start up and seems to be using oil at a concerning rate. 200+or- miles off road riding and its almost off the dip stick? The bike runs great any thoughts?


    PS actual mileage on bike unknown previous owner didn't know. I've put 1000k miles on it since owning it. I think the bike has a 385 kit so its had motor work done.

    To go from top to bottom on the dipstick is only a few ounces of oil. Personally I wouldn't worry about it - Just be sure to keep an eye on it.

    No offence but are you sure you're checking it correctly - after it's just been run? If not, you could be overfilling it, which will cause it to use more oil.

    Are there any leaks? It's hard to gauge how much you can lose to a leak - When the engine is hot and the oil is pumping it can sometimes drip out pretty quickly.

    Once you've eliminated leaks or overfilling and if the consumption still bothers you, the fix might be as simple as a ring job or replacing valve-stem seals. My opinion: as long as it's running ok, keep your eye on it, top it up frequently and carry a small container of oil with you if you go any great distance.

    That is a Baja Designs conversion kit from the mid 90"s. The same one I have on my 90 dirt model

    OK, so I allowed the movers to move my bikes. Mistake number 1. I asked if they needed to be drained, and they said no, because I would be there on the other end to receive them.

    Long story short I was not able to make it on time across the country, so they got put into temporary storage.

    Upon inspection of my bikes, I found that they had pulled the fuel lines to drain the tanks. OK, no biggie. I go to change my oil last night to get ready to ride into work this morning on my DR and I smell fuel in the oil. I have never had this issue, and had changed the oil a few months ago and put very few miles on it since then.

    Am I looking at a huge issue here? I put in new oil. Is it safe to ride around a little bit, then drain it again and see if it still smells of fuel, or do I need to be sending it in to have the top end looked at?

    Thanks in advance for any input.

    i would flush it out with fresh oil, maybe twice, then carry on as usual. the top end should be fine.

    Your engine was stone cold when the valves were adjusted, I hope?

    Thanks for the confirmation of fuel valve bolt spacing. Makes life much easier.
    Them wee side valve engines will NOT tolerate a leaky petcock. Drains right outta the carb into the LH main bearing..

    Thanks for the response. No leaks and yes checking when hot. Ill just keep watching it already set up a small oil bottle for the bike.

    Mine was using oil similarly to yours when I first got it- off the dipstick after 100-200 miles, even less if there was high speed pavement riding involved. It eventually drove me insane and I pulled the top end and found a very stuck oil control ring. I ended up with a procycle 385cc kit, but I'm sure I could've gotten away with just a new set of rings or even simply cleaning up the old ones along with the piston. Now I rarely add oil between changes and no longer have an msr bottle full of oil living in the bags permanently.

    As it is, just make sure to keep a close eye on it- seems like these things really don't like running low.

    oil check if cold requires 3 minute warm-up then wait 1 minute then check.
    If hot just wait 1 minute after shutdown.

    My DR has ~9000 miles on it and last riding season the clutch started to slip sometimes when I put it into 3rd gear and hit the throttle hard.

    I've just got the bike on the road and its still doing it although now its doing it sometimes in 4th gear as well (happens off and on).

    I have adjusted my clutch lever so there is no play in it, basically I just have to pull the lever in and I change gears.

    I tried lubing my cable but it has a plastic sheath over the wire the slides inside the cable housing so I can't get a cable lube needle inside the housing as there is not enough room.

    Is there any adjustment I can do at either end of the cable that will help to sort this out?

    If not, how long can I ride the bike like this before something could go wrong?

    I wonder if its because I jdid the air box mod and just last week installed a pumper carb from Jesse....?

    Thanks for helping this newb out!

    You want play in it, that means the clutch is completely engaged. I set mine up where the lever flops around free and you have to pull it in an 1/8" before it actually grabs the end of the cable. Do you have a manual?
