suzuki quadzilla bottom end... hmmm
Well that is somewhat promising. I have been on the phone with CPI several times over the last few months inquiring about "when" this will happen and it will become a production item.
Did they send you this pic? have you got more info Bob?
I am wondering about clearance for the carb and exhaust in out frames... oh as well as the tank too... maybe I shoulhang onto this old steel chasis for a while...

CPI Hy-In-Bred
I have seen this motor up close, the guy who built it builds motors for me. I got to see the cylinder off the motor, it's a real monster there's no doubt about it. It's going to be a very tight fit in a steel 500 frame and in an aluminum frame bike, it's going to be too close to call. Plug will be very tight on a steel bike with the spacer plate. The cylinder is wider than a cr 500 cylinder but the stud pattern is the same as the cr 500. You put the spacer plate on then bevel it and blend in the transfer port area of the cases to make everything work. Should be real easy. I was suprised that the real stud pattern of the LT 500 suzuki was the same as the cr 500 for this to really work. I know the guy that cut the spacer plate for the LT (did it on a water jet) and it took him awhile to get it just right. The head on this LT based motor is a custom piece and has two spark plugs, will be interesting to see this thing run. It's in a custom drag chassis for dirt drags. Hope the tranny can hold the power, they are thinking it's going to be in the 120-130 hp range on alky.

yup that's my mistake, I knew I lied about this a bit after I sent it. LT 500 rear studs aren't in the same location but they were close. The stock holes were welded and redrilled, front stud location on the cylinder is just like you discribe.
At any rate, I've seen this motor and it's quite the cylinder. It's a massive piece and the port layout is really nice. Alot of thought was put into this.

Funny you mention that cause Calvin told me he was building one to go on a quadzilla 500 bottom end in a quad, and I kept thinking ...theres way more cr500 bottom ends available. The CR500 transmission is one fo the most stout, Maybe the quadzilla motor is counterbalanced and this one already had billet gears and a built transmission, or wont fracture the motor mounts from vibration like the cr500 does in a quad....
i think I recal Clavin also stating this one had a lockup clutch.
Biggest power gains will be seen in a quad chasis, as a bike mx tire is traction limited to about 65 RWHP as I understand

that is Packards billet fuel bowl, it replaces the standard Lectron semi-clear bowl, it doubles the capacity.
The the pulse style fuel pump is located behind the motor with grey lines to it.
The lectron fuel inlet is normally on the left side of the motor but it does look as though a second feed has been added to the right.
I have the same 50mm carb but have the same CPI casted dual inlet bowl.
It has to 2 float needles

maybe for dirt. put a nasty paddle tire on there for sand duning/drags, or in a hillclimb bike, and you just found a winning combo...dubious01 wrote:Funny you mention that cause Calvin told me he was building one to go on a quadzilla 500 bottom end in a quad, and I kept thinking ...theres way more cr500 bottom ends available.

The Liger cylinder was not originally made for the quadzilla, Pete was given one to look at and give calvin his input about it.
Next thing you know pete has it mocked up on a zilla bottomend and wanting the rest of the pieces.
The head was not made yet neither was the adapter so pete made the spacer plate and head himself.

the outlet on the reed block is the pulse signal to the difram style fuel pump....my 3 500 motors all had this mod & needed welding up.

I have heard of guys gusseting everything and still fracturing motor mounts from the uncounterbalanced vibes with a CR500 motor in a atv chasis, other wise many would ahve dumped their suzuki motors for a cr500 engine. The quadzilla motor is famous for blown transmissions, but a counterbalancer seems to be required.Tharrell wrote:My 250r was counterbalanced, that makes sense.
Strengthening the chassis wouldn't be easier?
although its been a very time coming, I applaud any development, especially something as radical as this engine configuration.
If only I could get my hands on a jug, pistons, plate and head asap . I got plans....
It involves ice and screws..., oh and I live on a lake thats genereally noisier in winter, than the summer....
