Thinking about plans for winter project
Diy Carbon underseat tank and tank dummy ala thorston
But i dream big...
Ive looked at this and drooled...
Google Translate 1315cc FTW!!!
182-190 hp at the HR and about 140 -145 Nm maximum torque
Is this as simple as getting 106mm inner cast iron sleeves x2 from la sleeve (LA-80 L-80)? ~$100-200ea
Ordering a custom set of pistons? ~$500? (je/cp)
Having crank stroked ape quotes ~$1k on thir site for 6mm+ but this calls for 11mm!!! even poss w/o billet?
Con rods custom jobbies think i need to order like 3k worth to have em made still looking at options...
Couple thoughts
Big Bore,
So obviously the crank & rods adds a lot to this whole shabang might be easier to just big bore and see where I am after that...
I have read on the forums people have gone +1mm +2mm w/o sleeving but i want to try and get 106mm.
With a stock crank thats a respectable 1122.5cc they are getting 163-170 hp at the RW and about 120 -123 Nm torque with just the big bore
Q1 Any ideas on 106mm piston price? je/cp?
I show 2 potential part nums from la sleeve
LA-80 & L-80 both are 105.8mm ready to be bored/honed to fit a 106mm piston one has a 3/32 wall and the other is 1/8 both are also 6.75" long...
The bigger is 4.437" od (~112.7mm)
The smaller is 4.375" od (~111.1mm)
Q2 would either/both fit safely? any idea what kind of alum outter i would be left with?
I know when i tear it apart these questions will be answered but id like to just order up my parts ahead of time
For fuel management i am planning on running a motty afr to piggyback on the ecu and would be building a custom exhaust...
