hi kev and kriss007

sorry for other replys for some reason my phone wont let me post a complete message.

KEV im getting engine for $1300 its a 2010 xtr model with 5000kms its from the project bike hypoboang was making (one with the ducati fuel tank) long story on his behalf so i bought it.

KRISS007 not sure what im doing with old motor the gearbox 3rd and 4th gears need replacing..$500 for yamaha australia just for gears only (have done a thread on kevs page with pictures of damage so have a look) plus gaskets and anything else.
I have found a netherlands site that does xt bit's cheap but the postage it what kills it. http://www.oemmotorparts.com/
i need would love to do a big bore or even a turbo unit..shame you and kev are on other side of australia we could have another project

Look for adventure time on ebay for the gaskets you need they are much cheeper than here and maybe contact them for a price on the gears.

An N/A Big Bore is the go! you will plenty of power, a turbo will add more weight to a bike that is already heavy.

hi kriss007 or kev

When i had my engine apart i did notice the crank journal's are quite large have you ever lightern and balance this? and what about the balance shaft could this be removed to lose more weight? im thinking of at least 5kg could be lost just doing this! then the lightern conrod and smaller crown piston. and then all the metal removed from gas flowing the head, thats got to be another 2kgs lost.
i know i will be told it cant be done or it has been done!!

If you add some more power, you wont notice the weight so much
its alot easer than trying to remove weight

Contact DL700 for a 5050 cam, port the head, I have +1mm intake valves spare,
KW or behive valve springs, mill the top of the cyilnder, +3 TB bore.
