Is there anything in particular I should be looking at: fuse, relays, etc. I plan to bypass the switch to see if the horn is actually dead. but I'm hoping its not in the switch, it seemed a little fiddly in there. Its funny I've had the Safari tank installed for only a few weeks and now it not working.............maybe a wire has shorted out with the new tank. Anyway, lots of thinking out loud here.

thanks in advanced.
Pull the horn off and test it direct to a battery with some jumper wires.

Mine died one day too, so got another from the wrecker. Dunno what it originated from, but it still works. I've heard that a few others have just dies too.

Alright guys and girls I have a question about the rear shock. I just bought a 8.3 rear shock from An inmate. i weight 190 lbs and normally I ride 2 up with my girlfriend who is around 130 pounds. The shock should be fun for the both of us. I also went to the local motorcycle store and bought new Shock fluid. I'm going to put in 3.5 weight do you think this is okay? The mechanic at the shop said 3.5 would probably be my best bet since I got the Stiffer shock and I don't plan on taking the bike off road.

What is the Wt of stock fluid? I would think you would want something a little bit heavier than stock fluid to slow rebound a bit. Stock is already a boinger with the stock spring. A heavier spring will rebound faster IMO and I would want that slowed down.

Stock is 3.5

Many riders have had good results by stepping up to 10w shock oil. It's not as good as a proper re-valve but will make a significant improvement over the limp stock setup.

While testing the horn directly like this also loosen and adjust the phillips head screw on the back side of the horn. The screw adjusts the contact points inside. At least half the time all a dead horn needs is a twist of the screw.

This is exactly the point I've been trying to make. The best route to getting more power out of the DR is to mod the airbox. The DJ needle is the best (only) needle that will make it possible to run an opened airbox.

Seeing the trends is interesting and educational but does not offer an alternative solution.

+1

Now if there was an alternate "jet kit" that worked better (than the ProCycle) I am sure many of us would buy it.

Does anyone other than Derek have the state of the art dyno & gas analyzer?

Since I don't, I rely on those who sell a complete kit to upgrade my bikes.

I am always trying to buy the best available too.
The best option I am aware of is the pumper carb and I will spring for that eventually.
But for now, the PC jet kit works a treat.
On both of my DR's.

You are in fact missing the point. The DJ needle provides richness at the bottom/lower middle/leanness up top (in terms of rpm) - the exact opposite of the trend that is required to get uniform mixture when modifying the airbox.

Agreed.

Based on the shape, and the trends that shape represents, it is the worst choice of the ones discussed so far.

Sure it does. Any needle that exhibits a trend going in the correct direction, that is one that, based on its shape, will provide a comparatively leaner mixture at the bottom/lower middle/richens up top (in terms of rpm), and is adjustable. That includes the FP needle (out in my opinion because it is likely to cause accelerated emulsion tube wear), both non-USA OEM needles, and the KTM needle.

Regards,

Derek

Are you saying that one of these other needles can be used with a modified airbox and give better performance than the DJ needle? Nobody I know of who has tried this has been successful.

I have been saying that all along.

What are their qualifications, what equipment did they use, and what does "tried" encompass?

Moto,

You help a lot of people on here and I think you have a lot of valuable knowledge. BUT, you come off a little rough. You have the "my way is the only way" attitude which isn't always right.

Owning my own dyno (one that handles up to 2000 hp and 1600 ft lbs of torque) and done custom tunes on fuel injection and carbs I know a lot of stuff like your CO2 analyzer are NOT the only way to tune an engine. If I can tune a fuel injection 630 inch blown boat motor without it I know a 35hp motorcycle motor can. Also, you spout off asking people stuff wanting answers they probably can't provide just to make your "ideas" look better.

You still haven't ever answered my questions on what BSFC #/HrHP and Fuel F #/HR you are getting on the DR for max power. If you can't provide that...well, YOU don't have all the information

.

Fuel question

Hi all:
Looking for some education.

I mentioned a while back that I get crappy gas mileage on my 2012 (41-43 mpg).

Tinkerinwstuff mentioned ethanol as the culprit. When I asked the dealer mechanic he suggested the same.

Anyway - I put in some startron enzyme treatment. Now the bike seems to need more throttle in first gear to keep from stalling. I had always thought the bike needed the choke left on for too long (maybe about a minute) but now it's even longer or the bike stalls.

Hoping someone can explain what is occurring - is this "lean" vs "rich"? Should I be using this startron stuff? The first tank did not seem to help the mpg.

Thanks.

The need to leave the cold start enrichment (technically BST40 carbs do not have chokes) active longer points to a lean problem. It sounds like the pilot jet may be getting some deposits in it.

Derek

Thanks ADV Grifter and the rest of you that came with suggestions regarding my feared gearbox failure. Internet was sparce but I'm now back at home. Turns out you guys were right. I need a new chain and front sprocket.
Cheers.
