I understand now, price is for the mentioned parts not fitted, $2380 (Approx �1480)

So additional costs still to come, machining the cylinder for the 105 sleeve, machining the XT cases to fit the 105 cylinder, balancing the crank to suit the extra piston weight, assemble of the motor, dyno time to tune. I look forward to seeing the end results.

correct Kev...Steve has some machining to do......I will do a big total at the end for Parts, Labour and extras.

Update on progress
 

I spoke to Dan at High Desert Dyno last night, to sort out the payment and delivery of the new parts to Steve Ruth. (Dan sounds a very laid back dude!).

Dan is guessing it will make 70hp, and 54ft/lbs
I am guessing 68hp, but 57ft/lbs (so we are both very similar, which is reassuring!)

So things are moving on ..and I must say it is all very exciting!

(It has all taken longer than I initially expected, but it is a "Winter project", so it really doesn't matter.)

Hopefully Steve will receive the parts by the end of the month, and the cylinder and liner have to be sent off for machining as one of the first jobs.

The cylinder will have to be bored out to accept the new larger liner, the liner fitted, and then bored out again for the new larger piston. Then the crankcases have to be bored out to accept the new liner.

Steve is going to weigh the new piston, to see if it needs balancing with the crankshaft/ conrod.

So, as Kev mentioned, still alot of work to be done before re-assembly commences.

I have slight damage to my generator, (my spare engine had been down the road), so I will try to find another.


I was going to get some slighly more offroad-orientated tyres, TKC80'S,....but I think I will keep my Tourances for now, certainly until I have got the feel of the new engine, plus it will give a more accurate comparison on the dyno, against my previous dyno's.

Right an update...

Dan was just about to send all the parts to Steve Ruth, and found the cylinder liner was damaged, so he had to get another one.

He has now sent the parts, and we should have them before Christmas.

The project has taken much longer than I initially thought. It didn't help with me changing my mind so many times, and once I had settled on the spec., waiting for all the Cylinder Head work, along with delays in postage, and damage to the Cylinder Head when it arrived with Dan, etc.

I am reluctant to get my bike out on the road after all the salt gritting, and I won't be having my bike out until it is looking more like Spring.

So I have turned my attention towards getting the bike "more offroadish".

I also still have to do a power run/tune on the dyno to get the final result of my DNA Stage 3 Airbox thread completed.......so my current engine is staying in the bike for the moment.

update...I spoke to Steve Ruth (engine builder) today, the parts will be delivered to him tomorrow, for a January build. Estimated completion end of January (which is my request as I have had an expensive Christmas!)

Total costs so far.

Spare Engine �300
Replace engine casing �30
HDD RETAIL PRICE for my parts �1480 including shipping
Import tax �72

TOTAL (at retail price for the parts) �1882 (gulp!!)

Still have to pay for Steves rebuild, he has totally stripped the engine, and all the machining, gaskets etc...(he had to do that to send off the Crankshaft)

The ECU is going off to Piasini in Italy for the re-flash next week, hopefully removing the rev limiter, and making the bike run above 7200rpm.

Now I am looking at a Water Temp Gauge, possibly a larger rad off another bike, possibly an oil cooler, I will have to see how much hotter it runs. It will run even hotter when bedding in the rings. And with my HUMM trip in Spain, I will have to make sure the bike is operating well within the parameters of ideal temperature.

Steve Ruth has finished my engine (bang-on when he said he would)...and he said also it all went together really well (big thanks to Steve and Dan!)

I also have an uprated clutch and fuel injection system, which is a bit of a surprise too! Yipeeeee!
:bcake:

What did they do to the clutch? The 700 Raptors run an extra clutch plate compared to the XT660.

What did they uprate on the fuel injection side?

Don't know on the mods..let you know. Uprated springs..

Just curious why you would go to the expense of using someone in the US, I would think that there should be someone in the UK to do the same quality of work.
Sounds fantastic and looking forward to seeing the final result.

Gstry..Some parts were "US only" or put that "High Desert Dyno only" for me.

So, that's how it is !
