Who says you cant get cheap hp. I have less than 150 bucks in a 2000 SRAD 600 and came away with almost 110 hp. I can probably get a few more by fattening up the lean spots.

K1 750 pistons
98 750 SRAD block
97 750 exhaust cam
Stock head
Srad 750 head gasket
Stock carbs
Already had a full Yosh and bmc race filter

um thats a tad more than $150..

the block is at least $150, then theres $200-$250 for a gasket kit.

pistons?

cam?

full yosh bmc?

by the time its all said and done not excluding the time to do all this its way more than $150 for the average end user..

maybe you got the parts for $150 but thats not what its going to cost the average SRAD owner, then you're talking a complete tear down and rebuild, thats time and money, how did you get away with not using new gaskets?

Well I guess if you don't know how to shop ebay you very likely would spend more than 150. The pipe and filter were already there as I suspect is the case with 95% of all srad owners. There are probably half a dozen blocks at any given time on ebay for 50 bucks buy it now or less. Same with the pistons. I did leave out the 750 head gasket which actually was the most expensive part at 55 bucks. As far as a complete tear down I don't know about you but I have always left the engine in the frame and removed only the radiator and exhaust plus the head to get at the pistons...something an average owner could do if they take their time and get a manual. Who cares about the time spent if you're doing it yourself ?
 
let me get this straight I may not be following correctly?

is this a 750 engine case with all other parts from a 600 or?

I sounds like you took 600 guts and everything else and put them in 750 engine cases along with 01 pistons and a 750 exhaust cam in the 600 intake position?

good numbers either way and prolly worth it if its a stable set up, but yea not many of us have a full yosh Ti exhaust, I wish, mine came with a full Ti D&D and I want it gone for a more streetable system..

can you elaborate on the build a little more?

is it a 600 bottom end in 750 case's with a 600 head on top or?
 
straight swap then, nothing funny for cam or ignition timing?

you must have went with all the old gaskets cept the head gasket then?

hmm, been a few threads on the subject I think this is the first one for me..lets hear that baby run man

but look at how flat that curve is, wow, whats the torque look like?

BTW thats a beautiful bike, sheesh


Unfortunately I didn't get a torque reading.The dyno was done at an open house event where dozens of bikes were dynoed for 20 bucks so it didn't come with all the bells and whistles. Rolling the throttle open in 1st lifts the front end off the ground in the upper rpm's no whacking required.I actually traded straight across a 93 ZX11D for this bike so my son would have something to ride.
CCM I have no doubt a really well tuned 600 SRAD is capable of the numbers you speak of. My a/f is lean across the whole run so there is room for improvement.

Hi

Just curious as to why you used K1 pistons as i have a 600 engine with 750 crank piston/rods bolted straight. What advantages did you go for with k1 pistons? or were they just laying about?

This is where insperation came from:

I too went to that website before I started and decided I didn't want to split the cases. Keeping the 600 crank meant I had to use pistons with the same wrist pin diameter and the same height as the 600 pistons but with the identical piston to cylinder clearance as the 750 SRAD pistons. If you look at the k manual and the SRAD 750 manual the piston specs are identical except the k pistons have the same size wrist pin as the 600 SRAD. K's are also 12.1 comp. ratio same as 600 SRAD. The loss of 25cc by staying with the 600 crank was minimal compared to the power gained and the ease of the project by not having to remove the engine/resize new crank bearings etc.
 
Great job, almost wish I had looked more into it know as yours has to be the quickest easist bolt on power/torque increase with cheap parts!! tempted to do this with another 600 engine i have laying about. Should be fun bike if your shorten the gearing as well.
