Too much time on my hands . . . Or not enough sleep?

BlackCote wear

It was back in January 2011 that I applied BlackCote to my frame during a winter rebuild.  I noticed that when I was rebuilding the engine that my skid plate had wore off the BlackCote.  I think I have a solution for that problem.

After some wire wheel brushing and clean-up with acetone, this is what the bottom of the frame looked like:

I have been very pleased with how durable this finish is.  I haven’t found a chemical or solvent that has removed or softened it.  As as long as an aluminum plate isn’t vibrating against it, it has proven very durable.  I don’t have a frame guard on the left side of the bike due to the kick stand, so this is what the frame looks like from boot rub:

I see that POR-15 has discontinued the BlackCote and is replacing it with Top Cote.  I don’t remember aerosols being available three years ago when I bought this stuff, but I will be sure to try that and not risk screwing up my paint gun.

Who needs a flywheel puller?  Some smart person decided that they would try to pry it off.  Problem is it didn’t work and the flywheel was still on and the case was ruined:

Carb cable boot – nothing like OEM

Motion Pro may make good cables, but their boots – not so much.

Motion Pro carb cable boot:

The inner diameter is way too big and doesn’t “catch” on the carb cap and just slips off:

Took some effort to get it on:

Clutch lubrication

The aftermarket baskets are going to do a better job with oil flow:

And with all the time I’ve spent taking the clutch in and out, I didn’t want to overlook the inner hub.

The stock inner hub has just 4 oil holes:

I kept things reasonable and added 12 more holes (16 total) that were the next drill size up from the factory oil holes:

Rekluse EXP – heavy wedges

When I was researching things on the Rekluse site, I noticed that the kits they had for several of the small bore engines came with heavy wedges.  The EXP I bought for Version 2.0 at $203 was a good price to begin with, but what made it even better was that it came with a set of regular and  heavy wedges:

After opening the EXP up:

Here is the heavy and regular wedge:

The heavy wedges weigh 10% more than the regular:

I kept the lightest springs (at least for a YZ 125) in:

I will see in a few days what kind of difference this makes.

Rekluse – rate of wear

After 3.6 hours on Version 1.0, the ATF wasn’t totally black and this was at the bottom of the oil I drained out:

I’ve installed a new set of frictions and steels with Version 2.0:

Since I will be keeping version 2.0 for a while, I thought I would monitor how much the frictions wear over time.  I soaked the frictions and EXP overnight in ATF.  I then marked two of the frictions so I could keep track of them.

#1 is the first friction in, the EXP is #2 and #3 is the third one in:

The plan is after some more hours go by, I’ll pull those out to re-measure.
