Countdown until the 2025 NEMRR season!

[butcher bergs]

Haven't seen a countdown thread posted in ages so.......

69 days



Currently working on reassembling my bike after breaking it down to the frame for a long-overdue cleaning and greasing.

There's not too many NEMRR peeps left around here, but I'll give that a woohoo!

[butcher bergs]

That's fine. It'll be a countdown for two then!

[Kurlon]

I have my licenses for the year, I have a bike that still needs some more break in time in the garage...

Waiting on too many things to make any decisions or commitments. Bah.

I have one bikes motor out and at the engine shop. The other bike is just a frame with a motor bolted in it. The third bike is in the exact state it left the last round in........... I have alot of work to do still but that's always how it goes haha

[Paul_E_D]

I blew up 2 motors mid-summer last season. I finally had a sorted bike for the final 2 rounds. So that bike is broken in and ready to go. Fingers crossed it makes it through the whole year. This is the least amount of work I've had to do in the off season for a long time.

67 days remaining!


Frame and swingarm have been reunited and it's time to move onto the engine work


One reason for the entire disassembly was to clean all the brown ash that collected while the bike lived in northern California.


Upon removing the valve cover to check out the cam lobes, I was greeted with a camshaft end cap that fell out at some point in time but thankfully the clearance to the valve cover prevented it from floating around. That was a bit unnerving to see but disaster averted!


Cam lobes appear to be in excellent shape though I'm not sure what to make of the appearance of the coating. I mean, it looks okay, nothing is scored but it just looks weird to me

[Paul_E_D]

Wait, what happened? A cap was just loose in there? THe bolts were in position? These thing strip out like chocolate. It's often possible to fit a longer bolt if you have stripped threads. Either way, I would meticulously clean out the holes and check valves before putting the motor back in place. The cam lobes look pretty mint to me. considering what they do, there is always going to be some marking and discoloration.

[Paul_E_D]

Some people install the caps with a little less torque than the service manual states.

[butcher bergs]

Not the camshaft caps. Haven't gotten that far just yet. There's a friction fit part that's pressed into the ends of the cams. One of them somehow friction unfitted itself.

3rd pic down, the end of the left cam (exhaust) has the cap in place, right cam (intake) does not.

[Paul_E_D]

Oh, weird, I didn't know that thing existed.

I learned the best way to prevent cam wear is to get a two stroke

Bought a superbike tail for the gsxr....... Not that it really helps finish any of the bikes hahaha

[butcher bergs]

Started measuring valve clearances and have 3 intakes to adjust. One of them is way tight.....as in, my 0.05mm feeler gauge doesn't fit.
Spec for intake is 0.12 - 0.19mm

63 days remaining!

[Mgiossi]

Wow that's pretty loose for spec. Just comparing to my SV the spec is .008 to .010. I run them on the loose side at .010 haha

[Mgiossi]

Scratch that. Move that decimal one over haha

Anyone have a remedy for mushroomed valve shims?

Anyone have a remedy for mushroomed valve shims?

Like the shims won't come out of the buckets??
