That's an easy one . It's because they don't get on here talking trash and making it seem like they are the only people thst know anything. ..unlike you have done. So when someone wants to pose as a know it all ( you) ..i say prove it. Still waiting on you to prove your superior work. Sent from a van down by the river

Allen head bolts. Stainless. Sent from a van down by the river

I'm still waiting patiently for pictures of your alleged port work...... you talk like you have it all figured out. .but still no proof. So in my opinion, your input is invalid. Sent from a van down by the river

I'm wondering if stainless steel is even that great of a material for this application anyway honestly. Sent from a van down by the river

Thanks for an honest and detailed opinion on them. A -arms are too critical of a component to cheap out on. Could be a bad wreck waiting to happen. Appreciate the heads up. Sent from a van down by the river

I guess you get what ya pay for in this instance huh? Atv galaxy has great deals on LSR Sport arms which are very nice imo. Sent from a van down by the river

Fireball isn't some fly - by - night company. They don't manufacture products that would bump steer. Their stuff is properly engineered You can't say that about all manufacturers though. Sent from a van down by the river

I recommend anyone even THINKING about taking advice from this dude to look through his posts over the last few years. ..then decide. Sent from a van down by the river

Or you could just buy a serval and blow the " as sent" athena kit away.Shoot..my dad's ported 4mm stockers layed the beat down on 3 ebay athena kits that I know of. And they weren't aggressively ported. In fact, my butt dyno told me they had at least the same amount, if not a wider power dpread. But glad you like them. Sent from a van down by the river

Nice crank for somebody. OEM webs and HR rods is the best of both worlds. Sent from a van down by the river

I'll make it simple for you. Just buy the Redline ported 4mm stock cyls I offered you. It's already setup properly and has domes cut to spec. I also have a 4mm Hot Rods crank. All you have to do is get a base gasket and put it together. You won't find a better deal on some top notch work. There's a lot if mismatched crap out there. .This is not that.

I also have a stock cyl 4mm setup from Redline if interested. I have too much motor junk laying around..trying to streamline things. Haha Sent from a van down by the river

If anyone thinks this is expensive. .try pricing new. Great deal! Sent from a van down by the river

New serval kit about $1175.00. Porting $ 250-350 4mm hot rods crank 450.00 Better bearings. 80.00 Total price new approx $ 2000.00. If you are interested in mine I can save you a nice chunk of money. Like I said I'm considering a more drag oriented setup is only reason I'm thinking about selling. Sent from a van down by the river

I guess I don't follow your question. But with this setup, you can assemble it yourself. No need for a mastermind, haha. The modifications have already been done by Redline Racing. It's been ported, tested and Dyno'd. A "stock" or "as cast" Serval makes a smidgen over 75hp. As you can see this one is worked over ,making 90hp. It is used , so I'll be cheaper than a new one...but a new one won't make 90hp either..unless you add it on from your builder..usually another 250.00 -350.00 on top of the parts prices. Sent from a van down by the river

A 421 serval is an aftermarket cylinder kit that goes with a 4mm stroker crank. It is geared toward a good all around power that is still user friendly and still hold its own racing. Yes, you can assemble it yourself as long as you are even slightly mechanically inclined. Sent from a van down by the river

Ditto.If you are in the market I might sell mine. 90hp/50tq. Already ported and ready to go. Thinking about going to a cub. Sent from a van down by the river
