Trackside valve adjustment

Sirref · May 28th, 2016, 07:29 AM

So last week my motor failed, Believing the issue was cam chain I replaced the cam chain tensioner for a noticeable change (didn't get it until yesterday) however it turns out the primary issue is in the valves.

So, I don't have a manual on me to get the tolerances. I also don't have any special tools such as a specific valve adjustment tool on hand.

Can the job be done without a valve adjustment tool?
If so, how do I check the clearances?
What are the clearances I need?

Hopefully I will be good to go to race tomorrow, as it is I am not sure if it will be possible. Thankfully this weekend has saturday as a practice day rather than race

Been learning a lot, in case anyone else finds this thread trying to figure it out themselves here are the answers to the 3 questions
Yes
Use a micrometer for shims and feeler gauges for clearance
clearances are:
Exhaust: .22mm - .29mm
Intake: .15mm - .24 mm

Now to hope I get this **** good to go so I can race

Oh snap Ben, glad you got your info. Now you just need to find the proper tools to git-r-done in time to make the 3 board.

Good luck sir!

It took some time, I knew it was out there but I lost my damn shop manual in my parents garage somewhere

Between this and my highside last weekend (complete with 3 cracked bones) I'm in for a wild race weekend no matter what

There is a backup plan, but I don't like taking chances with unfamiliar bikes especially when I've already missed all 3 of my practice days...

I'm sure you know anyone & everyone in the pits will be glad to help however they can: tools, experience etc
I have yet to find a pit where someone wasn't ready to give the shirt off their back. Don't be shy to ask one and all!

Edit: I see it's not your first rodeo! Good luck getting it done and getting out there! 3 cracked bones and you're still campaigning! Awesome!

I'm pretty sure Sirref earned something like this, I just didn't come across a good place to post it last weekend:

Achievement Unlocked: Silver Lining

For a guy who had his bike go down due to mechanicals, then highsided another bike the same day, he seemed downright upbeat. Considering how I think I would've reacted, and the number of people there who seemed down just because of the constant rain, Sirref must have an incredible eye for silver linings.

Something like this maybe.

Any day I get to ride is a good day. I did feel bad about flipping that cbr but I knew the ninja was fixable and I didn't break my neck (did break my arm it turns out)

Issue with the bike has been diagnosed: skipped timing, I'm one tooth off on the intake cam. Not too big a deal but it's not something I'll be fixing trackside. I have another 300 on the way to race this weekend and I'll have it good for vir/njmp/mid-O

Finally got around to swapping this one in

Hopefully I'll get my bike running soon and we'll be able to ride together for reals next time rather than being on the opposite side of the track

Lots of time left in the season, so I'm sure it'll happen. Hopefully sooner rather than later!
