Hello I am looking at buying a Rovan 5b baja for sand dunes for this summer. What is the best engine from rovan to modify for the sand. Ty for am help..John.

Phenomenal job. Do u have a instructional video or a how to pdf so I can try it myself thanks.

I have a couple questions... 1) With the cc pretty much the same, why would someone prefer the small bore 39 to the big bore 40? Aren't big bore supposed to be more powerful, or does it not matter when the cc are the same. 2) With 38 and lower it's easy to find the parts to build an engine from scratch. You talk about getting cylinders/pistons from Athena, but what about the rest of the engine. Where do you purchase a crankcase/crank for a bigbore engine if we want to save some $$$ and build it ourselves?

I need that motor and pipe

how can i get that manifold for a 46cc ?

Can I do a redcat dunerunner with that engine please let me no

I need a professional consultation for my scooter engine project, if you’re interested. The objective is starting with either a Zenoah 43L-D or a Chung Yang GP460 stock engine, and ending up with something like a 65ish cc big-bore stroker reed-induction racing engine running on ~120 octane premix with Castrol 927 at 25:1. The 43L-D and GP460 have a 40mm and 42mm bore respectively, and both use a 33mm stroke crank. I saw in one of your videos, your crank guy fab’d a +3mm stroker crank for one of your builds. I cannot find anyone who mass produces these, but my goal is to end up with a 36mm total stroke.

I got A45CC Robin motor and I want to make a 45 CCmotor and I want to make read valve

What’s the carb setting I have the same one but can’t keep my 40gt on

Whats up buddy it's been a while. Double trouble looking for a race. 😊

Sounds like a monster

I need you man

I need to send my 32cc Rampage MT motor really lil slow to me because it's a big truck

I have a zenoah 29Cc what can we do to make that rip a bit more ??? Could you help me out my man. Seem knowledgeable I really can only work on these to an extent

I wish a had a big bore lol I'm the guy Vance has been helping with my Taylor 35 v2 and I got it out today and she's nasty but it's hard to tell cuz I use to run it in my 5t but I ported the exhaust a smidgen and polished it and I did the transfer ports just around the edges and it helps she got pretty warm but I was really ripping it but I keep it a tad rich thanks for your help also brother hope pops gets better 🙏

Oh' my Boss i never have 🤝 ever have!. Now u have on massive Zylinder in ur hand's & port on.

It's very nasty !!

Prob ran lean or something got in there

What if I'm able to slide a 6mm allen head through that gap? What are the pros and cons of raising that gap more than your 2mm example? Did I just waste a cylinder?

If you have a 32cc engine can you change out the head and piston to a 36cc or bigger?

Oh' my Boss i never have 🤝!. Now Show by SRE costom some witch sign. Oh' & some WAR exident Guy. Name: DER krig's Krüppel Drive oud.

I can’t wait to see this thing run

Got any updates on the nitrous vetka?

Sick

Rippin

That’s awesome. I like the low end.

I’ll buy a plus 3 mm for my 460 let me know !

O'Reilly Squares

do the reeds need way more fuel on the low need?

How do you choke it?

Good stuff brother

I sent you a email, you think you can help me with one of these, got the billet case

Going from 1.5 ratio rockers to 1.7 would be 65 to 70 added lift .unless my math is wrong.

would like to know what kind of gearing hes running!!

Can’t wait till mines is doing this

What a awesome power 😮 ... is that engine from 30° North ?

Man, that’s a lot of power!!!🫡🫡🫡

I would like to port a rovan 71 cc but not sure how is there any videos on tips on how to port a 71 cc for good power and were to port it

Good vid you know alot more than most

How much for a pipe, for a 50gt for a baja

Does this engine need to be ported for power or does it have enough power and torque for wheelies and speed

Is the 71 cc engine any good I’ve heard bad thing and good things about it
