Baja 5b What is the typical Top end speed for a stock 5B?

Hi all I just got a used 5B and upgraded the 26 to a CY29RC engine ( i got this engine a few weeks ago when DDM had a daily special, this is the engine http://www.davesmotors.com/s.nl/c.88...t.A/id.4519/.f)

So my question is what is the typical top speed for a Baja 5B SS stock out of the box. Would I expect any top speed gains with the CY29RC engine I just bought.

I have read about large cc engine have lower RPM but I am not sure how my new engine compares to the 26 in term of top speed. Also my pinion, spur and tires are all stock.



I have clocked my Baja 5B with a radar gun going 41MPH with the CY29RC, but it "looks" like its going so slow. Do you think changing my gears to 18T pinion and 55T spur make a big difference? Is the CY29RC strong enough with this gear change?

Sorry for all these questions at once...thanks

Hi,

Do you have an tuned pipe ? if not.. i'll sugest you the Jet Pro V3.. to get the craziest top end and very high rpm revs..

If you keep 17/57.. you will probably do 42mph..
With 18/55.. you will hit 47mph maybe

there is a thread on the forum who will show you how fast you can ride


--

My Brother hitted 52 mph with 20/54 .. riding the 26cc stock engine and a Jet pro V3 .. but with a 5T gear & 5b tires..

On the road, it might look slow but if you riding outside every where... you will be happy

I have Dom V1 already... i guess this pipe is good for low to mid rang power?

I think i might have to go with the 18/55 gears and see how it turns out.

thanks for the info!
