Speaking of balance shafts....


Something has been eating me lately, well, more like my counter balancer




The only thing behind it is the cam chain and what used to be behind it, the lower end of the cam chain guide opposite of the tensioner. Some how, it managed to find it's way out and lodged between the primary gear and the trigger wheel.





The piece wore a groove in the pulse generator but it seems to be fine. I am guessing the groves in the balancer are from the cam chain shuttering and if they hadn't hit that, would have probably derailed and caused a big dent to appear in the piston. When I thread the cam chain tensioner caps in, I should get 6+mm of space between the case and the head of the tensioner cap, I get maybe 1.5mm to 2.5mm of gap. I am replacing all the tensioners and chains, after 10 years of heat cycles and vibration, I'm not taking chances.

Maybe they were stretched enough to allow enough of a cam timing change that the new ones will bring back a few ponies, but I doubt it!

Oddly, the inside of the basket's wearing surface looks fine as well as the bearing, but the shaft does have 2 wear tracks in it and the difference if I remember correctly was about .01mm

The ears are dented from the fiber plates so I'll file those down. The plates are still in spec but both pressure plate surfaces have taken a beating.

I did find one other odd-ball thing. For some reason the chain slider on the swing arm got cocked towards the shock and by the time the chain reached the curve where it wraps around the swingarm, the chain was fully on the left side of the hump that runs down the middle. I made a sheet metal bracket that is behind the frame and under the new slider to keep it from drifting off center.

I wish there was a mechanical plus hydraulic cam tensioner alternative, something that could be adjusted to take up most of the play and oil pressure taking up the rest....

If you're going to replace the shaft, or not, wouldn't be a bad idea to upgrade the basket...no steel band on the newer one. You would expect the bearing to be the weak point and wear out first, a bit of play is normal. Source a new bearing from a bearing shop, they are not cheap from Austria and compare.

Installed the Christmas Trio from Rottweiler/CPR Fab, HT Racing 2-into-1 pipe, Rally tank, SAS and Canisterectomies, Seat Concepts seat and re-wired some aux lights.








And, since this is a show off thread - a pic of my bike out @ Lake Berryessa before I did any of this work.



A few more things to finish up and then to go for a ride!

Looking at it, it shouldn't be hard to make one like the Tokyo mods units

They try to get the weight off using a screwdriver or similar. Bad disassembly skills if you ask me, in a previous life?

Could be totally wrong but looks like.

Can I add also, this is in the wrong thread, it should be on it's own or in a similar mech type thread, not a 'show off your bike thread'. Can we move this discussion elsewhere?

Sorry, wasn't meant to be, you all were showing yours off riding the open road, I was showing mine riding a repair stand exploring my garage!


I'll be on the road in 4 weeks, hopefully with pictures worthy of a post.
