Hi all. I have seen the extended pilot mixture screws for the 1100 that can be adjusted easier. My question is does anyone know if someone makes them for the 650? The ones i see all say for tye 1100. Thanks in advance.

the 1100 pilot screws are completely different form a 650 pilot mix screw, even have different oem part numbers, but what you can do is cut off a screw driver or just use a bit and epoxy it to the pilot screw to make your own extension, the one on the back carb can't be too long or it will hit the air duct, no one makes extended screws for a 650, i did this on mine so i could adjust it with the engine running with the air filter connected, i used a 1/4 drive bit and use a 1/4 open end wrench to adjust the screws, the best setting after removing the final baffles was 2.75 turns on each with the stock #20 pilot. i also had to install a nipple on fuel can so i could get fuel to the carbs with the tank off, i just hung it on my windshield and ran a hose to the fuel filter inlet

Thanks for the input. If that stupid upper air duct was a 1/4 inch shorter there wouldnt be a problem. Air filter housing is a 2 second removal but that air duct prevents me from getting straight on them. Mine are at 3 turns out now. When i bought it the bike wouldn't start on its own without blipping the throttle, idle set at 900 carb sync wayyyyy out and front cylinder was dumping fuel out the exhaust. Got it mostly lined out with a carb sync, sum sea foam and bumping the pilot screws but still need tweaking. Probably just pull and clean them next rainy weekend.

that's why i only epoxied the bit on the rear pilot screw as the front one can be adjusted with the air filter installed, makes me wonder how the factory fine tuned it for emissions especially with an exhaust crossover on it.

It doesn't matter that there are different part numbers for the OEM screws....this aftermarket screw will fit either the 650 or 1100....we've done it dozens of times....available from Metric Magic for $40.00 pair..

Well, I'll see how it goes. Was looking for the metric magic but had trouble finding them and i was frustrated cuz my big freezer crapped out so alcohol decided i was buying the maxmix ones. If they don't work it'll give me something to throw, lol.

LOL..I know the feeling. Tim's stuff is a phone call, not internet ordering. He wants to be sure you get the right stuff.

With the Mix Max, just check them a couple of times after you've ridden a few hundred miles, it just takes a couple seconds. Also make sure you get the O ring and spring out of the hole before putting the new ones in.....

i wish i knew that before i glued a bit onto the screw, thanks good to know, if ever need to change em out i'm going with those for sure, i'm waiting on my 2005 used transmission, i'm going to pull a marathon when they arrive to get it done in 2 days,maybe one. 5th is really starting to howl, i looked at lot used trannys on e-bay and most of em the 5th gear on the counter shaft have pitted and flaking teeth , i thought this happened only on early years but i see it from 2004 and down, i post a pic of my gear when i get it out, i'm betting its pretty bad judging by the sound its making, i hope the bearings are ok. tranny was 40.00 free ship and gaskets to do the job 104.00

I've read trans / final drive issues on a few earlyish vstars. I'm determined to make a reputible bike out of this 650. Lol, yet to find ne thing it can't do. Even with the carbs a mess.

you can always stretch the spring to it make tighter, i used to do that on lawnmower engines all the time

there was never a defect on final drives in any years early or late, they only fail if the splines go dry, i'v heard of a few pinion shaft bearings failing but that could have happened from improper adjustment on the bearing retainer at the factory, yamaha should include greasing splines in there maintenance schedule

Didn't mean to imply any defects. Just poor wording on my part.
Well....guess I'll be callin tim cuz maxmix says that despite what ne one says that those screws will 100 % not cross over to a 650 and are for the 1100 only. Now i now, lol.
