you need one of those little nobby screwdrivers that are only like 3 inches long.

jeremy_nash · April 26, 2010, 07:09:57 PM

you know the cheap screwdrivers with the exchangeable tips? use just the tip, thats what I did, and it worked fine

Jlittle · April 27, 2010, 06:30:40 AM

I messed with it for a good hour lastnight. I screwed them both in all the way then 3 turns out, still popped. Then some fine adjusting and i still had popping so im not 100% sure whats going on but im going to get a carb sync tool today and some tube to test the floats.

Wish I could have responded yesterday.

The most important thing to do every 4000 miles is to check the valves, as these will affect the carb synchronization.

1. Check valves
2. Set mixture screws
3. Synch carbs

Synching the carbs before you do a valve adjustment, means you will have to do a carb synch AFTER the valve adjustment.

ok thanks, this will be my first time tearing into the valves i paid a stealership to do my valves last time. this should be a experience

Jlittle · April 27, 2010, 12:38:23 PM

.038 doesnt fit under any of my lobes... i think they need some adjusting

Jlittle · April 27, 2010, 01:04:51 PM

have no idea how to get the shims out without a shim tool.

you can unbolt the cam bearing caps and lift the cams up. just make sure to measure everything first so you know what clearance you need to get to. then lift the cams up, get the shims out and measure them. once you get the shim thickness, go up or down sizes depending on the clearance you need. good luck!

But be careful not to allow the chain to move across any teeth or you may bend a valve.

Before unbolting cam caps, make sure to turn the motor to Top Dead Center (TDC) and look at the cam markings so you can line up the cams with the crank when you bolt them back up. And, be careful unbolting the camcaps so you don't bend a camshaft.

my shim sizes are 262, 268, 268, 280. What would the shims sizes down be?

romulux · April 27, 2010, 04:26:23 PM

They're available in .05 increments.

So:

2.60 2.65 2.65 2.75

Or, if you want more clearance:

2.55 2.60 2.60 2.75

Jlittle · April 27, 2010, 04:59:30 PM

i think mine are smaller than they are labeled. I got some from the local cycle shop for free and they were a step down and still couldnt get a feeler under it so maybe it was worse. I will measure them tomorrow, ive been bickering with the bike for over 5 hours now and am going home. lol Thanks for all the help guys. I dont know how yall do this every 4k miles hahaha.

pandymai · April 27, 2010, 07:51:44 PM

just keep at it friend. im not sure mine are spot on either, but i messed with it for at least an hour.

romulux · April 28, 2010, 04:34:37 AM

You should measure the shim thickness with a caliper, don't go by what it's labeled as.

Jlittle · April 28, 2010, 11:54:55 AM

guess what guys... its done and everything looks good to go after 2 more trips to the bike shop. Putting it back together now. Then i guess fuel/air tinkering?

COGRATS! haha

im still working on the pilot mix screws and float heights. stuck at work though so cant quite get to the good stuff.

Jlittle · April 28, 2010, 12:24:13 PM

Thanks, it feel 1000x better than i did this morning before comming in to work on it. ugh lets hope i didnt mess anything up in the process lol! Good luck on the jets, ill be rejetting here in about a month or so.

pandymai · April 28, 2010, 12:43:54 PM

cleaning and rejetting is easy. it's the adjustment that's difficult. the whole process is slightly subjective. so go with what you feel is good. =]

Jlittle · April 28, 2010, 12:56:27 PM

im warming my bike up to adjust the air/fuel now and its poping quiet a bit just warming up. I have it set to 3 turns out. Is it in to lean it out to richin it up?

scratch · April 28, 2010, 01:08:41 PM

Considering the screws are mixture screws, they allow both air and fuel. But, the more you turn them out, the richer the mixture.

Popping - The valves are all within spec? Float height set properly?

How is the throttle response?

problems again. going insane =(
