750 liner
Posted: Thu Oct 11, 2012 11:00 pm
Well here goes
hope i can keep it more current than my facebook
Kim and myself have brought the liner Bob Proir started and Bones added to
Its well underway and a very nice job , esp to me as the work done is in areas i could not do as nice
Probably a few things i will change for fitment of the motor , cooling system, fuel system, oil system , safety gear etc
Lots to package in a small space
As we got it from Bones
frame
front end
rear
Took a leaf from Luckys book to transport it to Vic
excuse the mess underneath , now in the shearing shed
checking the fit of the 750 motor
Currently the plan is
methanol blown 750cc , no intercooler but a methanol injector in the turbo exit
we were getting oil pressure drop this yr i think from a windage/volume thing so will put a dry sump in with increased capacity over the std system to hopefully have oil available to the pressure pump all the time ,
also looking at a mechanical fuel pump, figure it would take ~ 18 amps to run a fuel pump with enough capacity and pressure to see 350hp and 28-30 psi inlet pressures (around 75 psi fuel line pressure) and the bike has not got enough amps spare to do that and drive a hi power ign system and injectors water pump , and boost controller etc
the other issue i see so far is the gearing Kim ran to go 238mph on the bike is about all we can do in 1st and still get it to get to the power range
higher compression to run methanol will help, but not fix the problem, and a push vehicle will also help,but as we were geared for 260 to get 238, i think i need 320 or so gearing to get the 300 that i am sure we can get to , what we realy need is a couple more gears
so thinking about the suzuki motor and how its crank cases are in 3 parts, gearbox separate to the motor , if i run a cut down second box , gear driven from the output shaft.(sort of like what Sam Wheeler is doing but at the other end of the range)
In 4th while the first 6 are used then 5 and 6 in the secondary gearbox i can get 8 gears (sequential gearboxes are not as easy as a car type h pattern would be with a second gearset ) and use a sprocket combo to get the desired speed
basic safety stuff still needs doing like frame gussets, fire system, seatbelts, finish the steering,outriggers, parachutes, , some is time dependant so don't want to get them too early or it will eat into there life just sitting in the shed ,
So thats the intent , i may well look back at this later and wonder just what i was thinking
