929 to 954

i want to know what is the difference between the 929 and the 954 engine beside the size of the bore and piston.
I ask that because I'm rebuilding a 954 engine and i want to know is the tranny the same and what else. because i have a 929 engine with low miles but it has a cracked case.

Transmission, clutch, oil pump, water pump, oil cooler, oil pan, clutch cover, camchain and guides and the head should be interchangeable. Cams are interchangeable but 954 have _slightly_ more lift.

What do you mean by the guts?
The rods are probably interchangeable but I'd use the 954 rods as I think they're lighter and stronger. Same with the crank.

Re: 929 to 954

cool... Can u explain compression, is it the more compression u make the faster the bike goes or does it make more torque and is there a difference.. i was able to to get my 929 up to 170, and while doing that my brother 04 cbr1000 was ahead of me doing 182 and a friend of our's on a 08 cbr600rr was right there with me and i couldn't get rid of him and there was no more throttle. so now up grading to a 954 with ported and polish head i hope to be to be right there with the big boys. Is there anything i could do to gain more horse power, i heard about getting better cams but i don't know which ones to get.
Also should i stay with stock piston or go for after market and which ones are the better ones. any minfo won how to upgrade my bike will be helpful.

You will need a _lot_ more power to increase your top speed. The 929 and 954 have little if any difference in top speed.
The higher your compression ratio the more power you get when you ignite the fuel air mixture. You get more heat than power though and the power increase is marginal.
Yes there's a difference. Torque is only relevant in trucks and tractors. You want horsepower.
Start with a good quality full race exhaust system, PC3 and good custom map. Then I'd try some cams. But the power increase from these is not going to make much difference to your top speed. The limiting factor is wind resistance.
Replacing the pistons requires a complete engine rebuild and any power increase is not going to be significant - unless your pistons and rings are very worn currently.
Don't they have any corners where you are? Bikes are much more exciting through twisty roads than straight lines.

Re: 929 to 954

Not really that kind of riding we have to go upstate New York Normally we ride the Long Island Expressway all the way to the Hampton where we have a 50 mile straight run. So we top out. I plan on saving my money to do alot of track time this summer. So from what i got i'll stay stock. I'll be buying a pc111 during the rebuild of my 954 engine because i want them to dyno the bike while it's there.
Blade what do u think of MMI school. I am in the process of talkinng to a recruiter on attending....

A fifty-mile straight run sounds bloody boring :-)
Maybe find some back roads instead of the expressway?

I've had conversations here and elsewhere with "mechanics" that claim to be MMI-trained. If they genuinely were then I would regard MMI as a complete waste of time and money. And the number of people that claim to be qualified US auto mechanics that ask the most basic questions about servicing their bikes is also scary.
Without a passion to learn, and to keep learning after you get your ticket, no school training is going to make you into a good mechanic. And if you already have that passion then you don't need the school training.

Are you building your 954 engine yourself?

Re: 929 to 954

no i'm not i sent it to a reputable bike shop that some of my friends use and he gave me a good price to do the work. I did that because i don't have the time to be down.... I have friends who are calling me to come work on their bikes, starting issues, changing clutch, changing parts here and there, nothing major.. I have my 929 engine that needs to be rebuilt so i'll use that as a project.......

Re: 929 to 954

hey Bladeracer i read on one of your reply that u can stroke a 954 to a 1024cc, could you take the time and explain to me what is stroking i heard its much better than boring out the engine.

Re: 929 to 954

Thing is... Even though you are on the bigger bike.. You dont make all that much more power. Then it comes down to aerodynamics, which rider can get more tucked and out of the stream. Then where you shift, even how long your shifts take

Allll about rider.

My buddy raced on an SV650 against CBR600s R6s and GSXR600s.. He beat them all.
Even then 1000s had a hard time beating him.

So if you think about it.. Rider makes a huge difference
