Resetting the valves

[Dart032]

Is it possible to adjust/reset the valves in your home garage? I dont have 250 dollars laying around in my pocket these days so I was wondering if I could do this myself?

sure is. I have never done a pre, but I did my post, and it was simple (just takes a long time to get to the valves)

You can as much time preping the bike to get to the valves as it is to do the actual adjustment.

However if you do not do it correctly and the nut adjuster looses gap, you'll achive a "burnt valve" condition.

Thanks alot that looks perfectly do-able..im fairly experienced with mechanics but have been having carb issues so Im thinkin why is winter and the carbs are off I my as well save myself some money come spring.

wait a second, what year is your pre 600?

[Dart032]

96 ..arent the valves shimmed or something complicated?

[arsenic]

yeah, those are shim valves, that $250 you got would buy 1/2 the master set of shims, good luck.

[Dart032]

meaning what its worth the money?

[arsenic]

look, I'll be honest, I don't even touch shim valves. Pay the dealership to do it. It's not that I can't do them cause I can, I don't have a master set of shims and I don't wanna buy one. Why do you think my project engine has a 98+ 600 head? 88-91 600's are screw vavles along with the 98+ 600's. the 750 has always been screw valves. 92-97 600 are shim's.

[Dart032]

well thats a sh*** deal lol. So lets say I put a 98+ head on there...is this a direct swap or is it pretty complex switch?

[arsenic]

a 98+ head is a direct swap, but you also need the 98+ cams. Shim valves have 8 cam lobes per cam shaft, screw valves have 4 per cam shaft. It's due to the fact that shim valves have 1 rocker arm per valve and screw valves have 1 rocker arm for every 2 valves.

You also DON'T need a master shim kit! There are MANY of us that have shim kits that will trade or sell you the shims you need. I have every size & thickness shim needed for a SUZUKI & will help you if you can measure & remove your shims. It is NOT rocket science & once you do the adjustment the first time you will see how easy it is. Let me know by PM if I can help you. Changing the head just because of this reason would be STUPID!

Many mom & pop shops and better dealership will also trade you shims -- you bring them yours and tell them what you need, and they'll trade you (might ask for $10 or $25 for the time/trouble). It's not unreasonable.

Things to watch for with the shims is that you get the cam caps & bolts for them matched to exactly where they came out of -- now switching them around (they wear specific to their location on the cams).
