Bad for economy ? Wash your mouth out, it's a race bike isn't it ?

The definition of a race bike is - A faster way to spend money.

Your magic white rabbit
Has left it's writing on the wall
We follow like Alice
And just keep diving down the hole

You can't fix your broken promise
Our ties have come undone
I will not be used to be battered and abused
It's the reason why I choose to cut my losses
Your lies fool no one
Your magic white rabbit
Your white room straight jacket

You can't offer your poison to me
In your kingdom of filth
White Rabbit
Straight jacket

Please advise what you're on Dave - i want some.

I've used some of those Chinese cable ties too - they do come undone. Use name brand ones.

The cam oiling is also very good. The cams are hollow and oil is fed into them with holes at each journal.

That exactly the same as the KLR. Oil enters the head from a pipe at the back of the head, goes to the left side inlet cam journal and is piped across to the ex cam. It is always the exhaust cam, right side journal that dies when run out of oil as it is the last to get oil. I have a rooted head (bought it that way) which I might try to salvage one day

[husaberg]

off topic but early 80's Hondas had cam bearing issues when they ran plain cams without line boring the tunnels to save $$$$$
thats also why you dont put in lab seals in say a kawasaki three without doing the same.

Mate Kevin has welded up one banjo bolt and drilled a new 1mm hole. We used pin gauges and determined that the hole was actually 1.3mm. Halving the area would have needed a .9mm hole but I added a small amount to be cautious. It's on the bike now and the 2nd banjo bolt with the smaller orifice has been replaced with a regular one so the only restriction is the modified banjo bolt. Dyno time is this Wednesday. Hopefully everything goes well. Kev is lending me his van again to get the bike to the dyno. I have a few electronic bits that aren't waterproof just hanging off the bike so it's a good precaution given the possible weather. I'm hoping to get video of it running and hopefully at some revs. I'm expecting less than 20hp given that it is half of an engine rated at 40hp

[speedpro]

Got a fuel pressure regulation problem which might be at least part due to alternator problem. Apart from that last night on the dyno went reasonably well. Got a peak of 20hp with a nice spread. Motor revs clean all the way to 18,000rpm but I have to check that in the logs. I was only going be the tacho.

And much was written about yamaha tachos in those heady revs days

Sounds nice and clean. What was Rob pointing out on screen ?

[husaberg]

Sounds great way quieter than i thought
how louds the induction?

[speedpro]

My guess is that the induction is nearly as loud as the exhaust, certainly from where I am. Rob may have been pointing to a speed difference we were seeing for a bit despite being in the same gears and similar revs. There was also a decrease in measured horsepower with no obvious cause. We suspected tyre slip but the loss was very consistent. The last runs looked OK if I remember. For a while the graphs also had an odd shape to the torque curve. I'm going to run it in the garage tomorrow to go over the charging circuit and I will also be checking the coolant. I had to add quite a bit to top it back up, more than I would have expected to need just for expansion alone. I'll sort out a better catch tank or maybe something just for testing in the garage.

I have a late model alternator rotor but am still using the original 2KR stator. The stator measures up at a fairly low resistance from one lead to another which is no real surprise. The reason I was measuring is that there is no output from the alternator. I can't find a parts fiche online to compare stator part numbers for early and late models, but I suspect that the later model rotors may have a different magnet layout which does not work with the early stators. I'll be looking at it a bit closer tomorrow but if anyone has any knowledge of these parts I'd be interested in your input. I also have the old problem of water being blown out of the radiator and a small amount of bubbles. It didn't look like much running it on stands in my garage but I'll be following up on that problem tomorrow as well. i'll be testing for blowby as per last time but it is pretty obvious, and disappointing. I do have another stator in my box of bits so will see if they look or measure any different tomorrow.
