Big Bore Kit
« on: February 28, 2016, 06:14:17 PM »
I'm curious if anyone would be interested in a big bore kit?

So far, I'm getting very little from CFMoto regarding the possibilty of a 1000cc for 2017, and in reality, that doesnt do anything for us current owners anyway.

I have a small stock pile of cylinders which I could bore and send out to have them Nikasil lined.

JE Pistons was more than willing to make an oversized piston, and do what ever compression ratio I wanted. Obviously the more I run, the lower the cost per piston.

At this point this is all just an idea, but it could very well be a possibility if I thought I had enough interest in them.

Mr. RPM makes an 840 kit and a 975 kit for the CanAm 800s, so most likely I'd say go 975cc to make it worth the $$.

Would anyone go for this?

Note, in order to do this, you will absolutely HAVE to go with an EFI controller in order to adjust the AFR, and go with a high flow exhaust and intake.

Most likely, I'd stick with stock compression, since we'd already be putting a little bit more stress on the motor with the larger pistons. If I were to go High compression, I would only go high enough to where premium would be required. Needing anything higher would make the kit impractical.

The other reason to go stock compression would be to leave the possibility of having a turbo put on.

Would love some input on this!

I would be interested if my engine was in need of refreshment but as of now it only has 535 miles on it so I need to leave it alone for a bit.

Im all for a big bore.  Especially if the 1000cc machine will have the same frame/body as we currently have then i see NO REASON at all to get rid of what I have.  Do you have an estimate of the cost of the "kit"?  I would do one im pretty sure.  I do have a couple questions though and they are more of "have you though about that" questions.  Are you thinking just bigger bore and leave the stroke the same (that would save having to do a crank).  What about the wet clutch?  Im sure there would need to be some kind of modification to get it to hold up for any real length of time (maybe slugging it??).  These machine seem to be REALLY good on cooling so i dont know if that would be a problem.  I lean more towards it wont be and could be addressed if it becomes one later.  Do you think the axles will hold the power?  I have not seen a lot of post on axle problems but you are going to increase the HP by about 1/3 so it may or may not be an issue.  Finally....the belt.  Man that thing will take some abuse when you up the HP but do you think it could handle it?  In all seriousness I am VERY interested in it.  PM me and we can exchange phone numbers and call/talk about it if you want.  Also we are dont live all that far from each other and Im up in the South Bend area to visit friends pretty often.  We could get together some time if this all works out.  Let me know what you think!
I can imagine a world completely at peace.  A world where there are no weapons, no war, and no violence at all.  And I can imagine us taking over that world because they would never expect it.

I do not speak English, but the stroke is 800 cc Can Am 0.5 mm longer 62 mm.
CF Moto is 61.5 mm. Piston pin 22 mm proplem cf moto and Can Am 20 mm.
The sleeve or similar needle bearing rotation rod. am getting a cam mounted on the piston. 860 cc  be cheap to buy. 975 cc in Finland to have been in 1700 e or more..

I would be up for one if I ever have the cash to spare. I think maybe 11:1 compression. Not too high, but a little boost. Does any one make cams for these? I'd like a Mud Buster. I know others would like more top end. I need low end. I think the wet clutch could definitely use some work, if the power gets much higher.

In no time you can just buy all the needed parts from cfmoto to up the 800 and improve the clutches or drive clutch we should say
If it has Pistons or Tits you will encounter problems.

11:1 compression you REALLY need to be running race gas (110 octane).  I my previous SxS had a built 11:1 compression motor and while it would run ok on 93 octane pump gas it showed a REAL loss in power doing so.  On 110 it really woke it up.  Now while i love the smell of race fuel burning and wish they made cologne scented that way LOL....at ~$8 per gallon at the pump and $10-15 per gallon in the 5 gal cans at your local bike shops it makes running them MUCH more expensive. Your talking a minimum of 4x the price of just fuel.  On top of that when you travel with it you HAVE to carry fuel with you or risk ruining your motor.  Or at least race gas mix in the small bottles and that still ends up costing you about $12 per gallon.  I agree that the clutching can be overcome BUT also it would be REALLY nice to have a dealer backing you up on this and at least sell you parts you break while sorting out all the problems at cost.  When you start shredding belts at ~$150 each and wet clutches at ~200 (im guessing prices and dont know the actual on these machines) it gets expensive.  To top that off you may go through 2 or 3 of each before you figure it out fully. 

I guess my point is that its not just "toss in bigger bore parts and your good to go"  99% of the time when you up the HP like that then you will have to upgrade other parts to hold it together.  Axles seems strong in these and thats good.  Guys are running 30's and not blowing them apart so i think they would hold the HP because 30's vs 26's %wise is about the same % of HP you are going to go up.  I think the real work would need done with the clutching.  I am friends (and have stayed at his house several times) with James Davis the guy who owns JBS performance.  He does A LOT of Yamaha clutches and Kawasaki.  There isnt a massive difference in them either so if it comes to it I will drive out to WV and he and I will work on the clutching on the CF Moto.

I can imagine a world completely at peace.  A world where there are no weapons, no war, and no violence at all.  And I can imagine us taking over that world because they would never expect it.

My Grizzly had 10.75:1 compression. It ran good on 93 and would run OK on 87. Some Corvettes have 11:1 and are designed for pump gas. They probably do run better on 110, but it's not a necessity. When I talk about the clutch needing work, I mean the wet clutch. You can tune the CVT any way you want it. It doesn't help much when the wet clutch is slipping. I don't want a WCD. That's the main reason I picked CF Moto over Polaris.

Emerson...with the upcoming release of the 1k are you still thinking about doing this?  I would be all for it because i dont see a need to get rid of a machine that I have built everything else to exactly the way I want it.
