Engine Question?

[tarzan13]

I have engin a base from original baja with blown top.
But the base is still good.
Can I put a CY27RC top kit on that base or bigger?
Want to make sure before forking some money on the project.
and can someone put one of those billit head kit?
thanks for your replies!

I looked into the Billet head a one time and was told by DDM that people were not having good luck with them, so they advised against it. So I went with the chrome version of a motor. People seem to love the 29cc kit. I think there are two different versions, one with a smaller cylinder longer stroke and one with a larger cylinder smaller stroke. Advantages and dis for both. I will look into my notes and see if I can find the difference. I know I printed it off.

but do they fit on my cy23 base?

[VertigoPerformance]

Yes they do.
I added the 29cc kit to my 23cc block
The kit comes with
Head
Crank
Connecting rod
Piston
all for $89.00

The engine ROCKS at a cost no one can complain about.

[tarzan13]

Can I use original connecting rod?

[mradlin]

I'm pretty sure the crank and connecting rod are one piece. The headkit that you buy should come with one! If it doesn't make sure you have the right crank for that particular headkit. A 29cc headkit uses a +2mm stroke crank for example.

Awesome hop up and cheap $89.00 usd

I dont remember bore sizes, but the diffrence on the 2 29's is on is 29cc and the other is 28.5cc. The 29 has a 2mm longer stroke, this motor is going to have more torque. The 28.5cc has a stock stroke, this motor is going to have more rpm. If you ask me the 28.5 is the best all around motor for a good mix of torque and rpms! And this top end kit would bolt right up to what you have now.

So Akela is the kit I posted the right one he could use? It is the one I have

[Doctor RC]

The kit Akela posted is the 36mm bore x 28mm stroke (standard) 28,5cc and the kit Mlocker posted is the 35mm x 30mm stroke 28.9cc.
The 28.5cc option is the best I believe from personal experience, I now have two of them after trying many other options. And as stated keep clear of the 29cc billet head. Looks good but does not develop high rpm at all.

[VertigoPerformance]

I just talked to Akela on the phone and he explained about the engines.
I will wait until mine dies then head for an Oneill Bros engine.. but now knowing what not many of us new a year ago I would have taken the 28.5 over the 29

[mradlin]

I'm also running a 28.5 on mine.

[tarzan13]

thank for reply!
getting smarter here.
so i`ve got a 28mm stroke so i look for a kit that is 28mm stroke and the reste is bore and the bigger the better but the longer 30mm storke,stroker they call them got more torque naturaly so its the same old story torque vs Hp.Right?

[mradlin]

It's more like Torque vs. Rpm. Any engine with the stock crank will be able to make more rpms.
