#6

[speedpro]

Geez, what a weekend. The motor is a gem. It fires up easily, most of the time, and the throttle response is amazing. It has a nice broad spread and I am only using three gears for the whole track. Going clockwise it's down one for the hairpin at the end of the sweeper, hold that gear till "just" before the right onto the main straight where I drop it down another one, and then on to the straight with a big handful, cranked right over, and shift up two before chucking it into the sweeper. A very nice engine that on that infield left hander is probably doing about 3,000rpm and yet it pulls nicely to the right onto the back straight and then just leaps to the esses. I've been revvng it to something like 11,000rpm and so far the vibration without the counterbalancer hasn't been too bad. Certainly nothing to worry about and probably better than a TS100.

Might be getting round time to sort out the other barrel and head!!

Chassis wise the bike is handling pretty good. I may need to remove about 10mm of oil from each fork just to allow the extra travel. It would be good to get a 2nd opinion from someone who knows about these things. I can appreciate a well setup bike but am not knowledgeable enough to get a good setup myself, not REAL good anyway. I've run it as per the photos with just the tailpiece but I've worn a reasonable amount off my right knee slider so I'm considering putting the seat on the tailpiece using velcro. It fits quite nicely and wont look too out of place. On the left in the infield I was getting some pretty good grinding noises but can't find anything other than the footpeg that was touching so maybe it's just noisy when scraped. I also ran the tyres down 1 psi at 17psi and 18psi F&R. On a really warm track both tyres were looking good and really sticking well. The rear was the only one to slip a bit but I was deliberately giving it full throttle in 2nd on to the front straight with the knee down and it would just slip/drift a bit and then away. Not bad for a tyre out of the bin. All up I'm pretty happy with it. I'll see JC about a run on the dyno to see what numbers I get. With these OLD Honda pit bike engines making 24hp I'm expecting about 45hp at the wheel

You've got proper USD forks dont you?

it just doesnt stop being funny (sorry dellorto)

Yoiu were looking real good out, and the bike certinly seemed to be going well when you passed me.

Just dont crash that spanking new paint job

Wouldn't handle without them... so I've been told.

Yep I am impressed and a wee bit green with envy. still, Speedpro's bike sure went brmmm brmmm allright.

In post #163 the bike is up the right way, as are the forks. There has been a bit of fiddling there though. Three sets of forks donated parts and some of them were modified as well, plus the cartridge emulators.

USDs would be a fashion statement at this level, maybe.

Thats just a running joke PT of skidmark's comments in the past. I'd say with a '7' for delivery.

Am I missing things again? The drugs are supposed to be taking care of that.

About time someone dredged this thread back up.

Finally had a full weekend out on the bike and have got all enthusiastic again, to the point of scoring some gas welding hoses off a friend, thanks Darren, and getting in and doing some maintenance and checking. Got the motor out as I want to do some minor mods and measure and check a few things. Found some interesting little wash marks on the piston crown adjacent to each rear stud and coinciding to the rear edge of each rear transfer port. The cylinder head also has an interesting carbon free area to the rear.

I've noticed a definite drop-off in power after a couple of laps. It was really obvious on the little back straight going anti-clockwise. The plan is to fit the water cooled head, 1 to test the thermosyphon function and, 2 to see if it makes any difference to the power after a few laps.

The ports are definitely lower than stock. Even with the piston at BDC the piston is masking the port by at least 2mm. Going to have to have another measure of that for sure.

On Saturday I gave Darren a ride. He had a little whine about the gear shift, something about getting his boot under the lever when cruising round corners. He reckons it's quite deceptive how quick you're going because it behaves so well, which is pretty much how I see it. Just need to push it harder now.

Will we be seeing the New #6 at Taupo this year?

[speedpro]

Probably. I'm planning to have at least tried the whole new motor by then, not that i should need it to sort out those pesky FXRs

How much power is this motor making mike? And how much less power does it make after it's got hot?

I haven't dyno'ed mine since my last run at 19.3, but it definitely feels much stronger after some simple changes. The bit I love about my motor is no matter how hard I thrash it, I cannot for the life of me feel any drop off in power which is great!

When are you coming to kaitoke for a spin? I'm keen to see these motors back to back.

[F5 Dave]

That's a queer looking carbon on the head. Obviously leaking coolant in. Fer Sure.
