The drum is an $80 part. So yeah not terrible to fix but I don't feel like putting that kinda time into it when there is a freshee sitting there waiting to be used.

Where did you get the SV650 crate motor and how much was it?

Got it from a place here in LA, story is the bike was brand new and got damaged somehow. Was a total write off. Blind luck on my part to get it, I just had to wait 6 months for it to finally clear the insurance crap.

How much did the valve clearance change between adjustments? What interval did u check valves?

I had them checked at the factory intervals.

600 first, then every req interval after that. It has not needed a valve adjustment till 45K miles and not another one since.

Yup which is surprising.

Other than, tires, chains, oil and filters the motor is untouched.

[sierraoffroad]

thanks for your reply. same here on the maint. items. all i have done is tires chains, etc.

I swear by amsoil but you sure can't convince the rest of the riding population.
Nice stats Dave.

Thats why I became a dealer. To get it at cost.

Like 15 years ago. I'm still broke.

But my vehicles run good.

How have you traced the problem there? Just asking as I have been around the sv motor a while and have not really seen trouble there, seen a bad detent though and several bad shift forks (but I was building race motors).
I would be surprised if the valves went if you kept them to the loose side of the tol. The sv-650 will break a bottom end when over revved on the track, and tends to wear out the cam chain guide in the front jug, and cam chain. I am thinking the tranny would be more likely shift forks.
My original wee (an 04) is in Newport Tn right now with about 138k on the clock and the cam chain is a little noisy as of june( this year last time I saw its current owner). The only thing done to this engine has been valve checks (15k set at max, 65k still in but tighter re-set to max, 110k re-set max loose but were still in).
Just to add to the oil thd(ugh)the 04 had only seen rotella full syn 5w-40 from wally world every 5-6k. (changed when the clutch got a little grabby)
I just did the valves on my 06 at 66,000 (second setting) and could have left them. I just set them max loose again, hint for you guys suzy shims(and aftermkt) are in.05mm increments(7.48mm O.D. shims) trade your shims with an old honda shop, honda shims are avail in .025mm increments. so you can hit your numbers closer(lap them if you really want to hit it spot on).
Valve guides seem to not wear much in these motors in my exp. if the buckets fit properly in the head
Just ramblings don't post much but this caught my eye

I assumed it was the shift drum based on a past experience, but without getting into the motor or trans there is no real way to determine the cause. It just randomly false neutrals between gears (all of them) which by my understanding was more towards the shift drum than forks since as I have been told the forks are specific to certain gears, and this is happening across the board.

Regardless if/when it gets bad I will just yank the motor then might dig into it and take measurements just for grins.

I started missing the random shift, when I went from my old sidi roads to a shorter toe box, pair of boots. that missed shift followed me at random on all my bikes till the new boots broke me in.

Yes I got new boots but this problem persisted for about 20K miles prior to the new boots.

Wish it was that simple..
