TBS hose connection pics

I started just to change my air filter and ended up installing the TBS hoses. The key to my success was the small hands of my 12 yo grandson , AJ and an odd looking curved set of pliers I got as a three plier set from Harbor Freight.

This is for a 2003 DL 1000. The sources I have are the Procedure Notes for DL650 for Throttle Body Synchronisation by RBS_Cairns and How do I adjust my throttle bodies from the vstrom forum. Some of the pics on the Cairns notes don't match what I could find on my 1000. I am not sure if it is because of the difference between the 1000 and the 650.

The removal of the gas tank was done to get access to the air filter. It had nothing to do with any instructions I have read about the TB hose installation. Although the tank removal helped in getting some good pictures of the TB connections.

Some of the pic are from a previous set about the fairing removal.

After the tank removed



This is the right side of bike. The pencil is point to the rear TB connection.



Another closer look at the rear TB connector.



Another close look at the rear connector with the hose attached. The wooden pointer tip is touching the hose.



The pliers used to install the hose.







The front TB is access while looking up under the bike like this.

This is AJ adding hose to front TB



This looking up at the front TB with black rubber cap on .



This is pic with blue arrow marking hose on TB connection



Next I route the hoses to the right side on the bike. I use plastic connectors and the black rubber caps to seal the hose.



Now I think I have the hoses connected to the TB correctly.

Next is to find the Balancing screw. The Cairns pic of the screw looks like this,


Is this it ?



Pic further back



Based on the description in the Vstrom Wiki

"located on right side of bike, on the front TB."


I borrowed a TwinMax from Chuck, Gilk51 , and will test how well I understand the process. Wish be luck cause I need it. If anyone can add to the location of the adjustment screw I would welcome the help.

Also , AJ is for hire if someone in the Arlington Texas area wants this done. It took him less than 10 min to install both hoses.

The TBS adjustment screw

I found the adjustment screw right where I left it.



I will use a long set of pliers to adjust the screw.

Just did mine yesterday...used a small ratchet made for screwdriver bits...allows a 90 deg angle and very low profile. The best part is it allows very fine tuning...using coloured water in a home-made manometer, I got the levels to line up perfectly!

Thanks.

3/16" vacuum hose from the local automotive shop. Internal diameter ~ 4mm. Other notes:

- I recommend longer lengths (1 1/2') to route them up and away from the engine block.
- I wasn't able to get the spring clamps back on, so used zip ties.
- I put a few drops of red food coloring in water for the homemade manometer. Those tube lengths were so long that it would only be sucked up if I am completely careless.

If you already have the tank off it only take a few minutes to remove the air cleaner, gives you a better view of the whole system, and you can adjust the TB with a screwdriver.

OK, I thought in order to sync the TB that the bike had to be in operating mode. The engine is running and the valves properly adjusted, air cleaner in place and you adjust the TB as you vary the RPM range while monitoring the sync tool, manometer or TwinMax and adjust as needed. Thatís why I took the time to install the TB sync hoses. How can the bike be running without the tank and air cleaner in place. Did I miss something. :?


Please help me out here . Pretend I am from Missouri (the show me state) and show what you are saying can happen. A link to a site that details this process would be wonderful.

I am always looking for a better way to work on my bike.

What I'm hearing (reading) is that it's easier to get to the nipples with the airbox removed.

When I do the sync, I just lift the tank which allows me to get to the screw and I adjust it while the bike is running.

I haven't removed the tank (to remove the airbox) and haven't disconnected anything else. It was tough to get to the nipples, but the front one can be done with just your hands, and I used a screwdriver to pry the rear one off (from the right side of the bike).

Quick question for you guys. I made the yard stick manometer using tranny fluid. When I tried to sync them up, they would line up perfectly and I would blip the throttle. As soon as I let it idle, the fluid would start creeping,(sometimes a fast creep :shock: ) way out of sync.
Is that normal?
