Those Honda tanks look great on BMWs. Loved the videos, but I think they were trying to convey a feeling, rather than represent reality. At the speeds they were going and with the amount of weaving they did, they'd still be stuck in the fog :-).

you've got to love the versatility of the airheads, just too cool.

Yeah agreed. We'll leave reality out of it & just enjoy the vibe of the vids.
I had a looksie at their website, some interestng things. i really like the way they've run the wiring in the bars & covered with fibreglass sleeving - quite cool.

Shit I really want to get out on Schmidt now tho.

If he's up & running I'll be doing a leisurely road ride prob around Moutere etc
If not I'll be taking the DRZ so can go anywhere.

Excellent.

The next step is a test ride to make sure everything works as it should. Don't wait until you are with others. DAMHIK.

Good work. Were you expecting it to not start?

It should pull a bit better now with the heads overhauled proper.

Bugger - somethings not right.

I went about zeroing the carbs & setting them baseline for starting etc.
I started ok & oil was dribbling out the rockers.
Covers back on & shit it sounded like a kanga bloody drill going off in the valve dept Triple checked the valves- I still find it tricky finding the exact correct spot for TDC per valve but pretty sure I had it right.
Started it again & still noisy so shut it off. Swapped valve covers over to correct side - DOH! That'll do it. Shoud be ok now....
Nup still really really noisy.

I think the only travelling it will be doing this week will be down to the mechanics in the back of the van

Hopefully it's a simple easy & cheap oversight

Basic question, but are you sure that you set the valves on the correct side i.e. only one side can be set per rotation of the crank. The other side is normally closed. If you got it wrong then the excessive clearance would sound aweful.

That is the question I have been asking myself & trying to ascertain. I get the OT lined up for one side after the inlet valve is opened & before exhaust valve opens. I use a chopstick to make sure the piston is at the correct TDC.

I'm pretty sure you're right but I have spent an hour trying to make sure I've got it right. I'm going down to have another go cos I think you're right & I would really like to have a short ride today on it.

Of course being the 1st fine sunday every bike in Nelson is on the road.



Unfortunately the black dog has been nipping at my heels this weekend which sometime affects my decisions & judgement however I'll try to outrun him & get Schmidtty up & running.
cheers

As an easy way to confirm you are not 360 degrees out, check using the Triumph twin method, don't worry about the timing mark and all the mental challenges this involves.

Exhaust valve fully open on the right cylinder, then exhaust tappet on left should be fully home and rocker loose. Reverse, turn engine until left is fully open then the right should rattle.

Repeat for inlet valves.

Don't worry, you probably just put the pistons back in upside down............

Don't you just set one side when the other sides vales are rocking.? You don't need to be super accurate because you are setting the tappets on the base circle of the cam and there are a lot of degrees of rotation while the followeres are on the base circle e.g. opposite the lumpy part.

You will find the issue soon enough, don't panic.

Yep, don't panic. I've screwed up a lot of stuff, trying to fix things that didn't need fixing, while I was in a panic.

Ok thanks guys. You guys were right. I overthought it. I looked on the airheads & the simplest paragraph said " at TDC 2 rocker arms will move - adjust those"
Sure enough it all went well.

As you can imagine the valve gaps were sitting at about 5mm so weren't quite as close as they should have been

Anyway I have some pics loaded so will carry on from where I left off with the heads.

I slid the barrels over the slugs remembering to have the 120deg angle between rings. Smeared some Hymolar blue around the base of the barrels



Torqued them up nicely. All the torque of stripping studs had me err on the conservative side.




I slipped the heads on & as mentioned before set the valves "excellently"

That is as far as i was going to fit with the engine out. I turned my attention to the clutch. I had purchased the budget option clutch plate from motobins as the existing one had lasted me a year while being past the servicable limit according to the manuals. I used the gearbox to centre the clutch plate & replaced the bolts. Smeared the tiniest bit of lube on the spline.





From there it was wait until a mate came up to help lift the motor into the frame, getting the mounting spacers in the correct way
That done it was simply a matter of plugging wires back in, fitting the gearbox onto the motor, airbox & exhaust.



Look at this beautiful air filter. Nice straight lines... sigh...
