Daniel who did Richards work is one of the best Raptor motor builders in the USA, he really knows these motor backwards, so all the work done will work 100%.

Steve said it was all "very nice".

Was the deck height adjusted on the cylinder?

Right, one of the important bits.. COSTS !

So far, these are the costs, (although Dan has done me a great "Development Deal",) but I am listing the normal prices...


I have started with a spare engine (optional).

1 x Pair +1mm Inlet Valves $70
1 x Pair +1mm Exhaust Valves $70
1 x Set of Springs $180
1 x Cuervo Racing Ported Flowed Head $850
1 x Used Raptor cam gear $50
1 x Rocker Arm Clearance Machining $50
1 x HDD 5050 Camshaft $300
1 x Gasket 105.5mm $50
1 x CP 105.5 11:1 Piston $260
1 x Liner (Supply only) for cylinder bore $110
1 x Valve guides $90
1 x Throttle Body boring $200
1 x Shipping both ways $100

TOTAL PARTS/MACHINING FROM HDD $2380 (Approx �1480)

I didn't have valve guides , but added them anyway.

ADD �190 for machining Crankcases, removing existing liner, replacing with iron liner, bored to suit piston travel expenses.
ADD �400 for labour to total strip/ rebuild, includes: Yamaha gaskets, Uprated clutch springs, modified clutch?, modified injection?, postage to USA, and other bits required.

TOTAL �2080. (at retail price)

Then plus oil, filter, coolant, �50?, dyno �150.

plus Piasini ECU �-?
plus uprated cooling �-?

plus optional spare engine, throttle body etc. (my one was a steal, a 5,000mile engine for �300), but they are normally �700-�900 from a scrap dealer.

don't know yet..I'll get the full run-down when I pick it up.

What I will say is Kev, we are not trying for the highest compression...we won't win that award! ...enough to do the job, but to also keep the lid on! And as I am not racing it, it sounds perfect to me. Easier on the starter motor too. 11:1 ballpark..certainly not much, or any, over that.

Expensive build.

Just trying to work out exactly what has been done to your motor.

richardsracingmad 03-02-11 13:07

yip...expensive Kev, but I am happy with that, in the knowledge that I chose a great spec, (that will work together very well,) and I chose the best guys to do it!

I'm happy!!:smilies0349:

If you are interested, you will find several pages about Steve Ruth on the HM Racing website...this link should take you http://www.hmracing.co.uk/Default.as...&intLevel5=592

..but go back to "2001 Enter the Supermono" intro...
