Bennett131 Posted June 1, 2016 Report Share Posted June 1, 2016 They never are anymore, 2 g just for internals will hurt but I will do it as money comes. I'm gone 5 days of the week as it is so it will have to be a slow build anyway. Thinking of picking up a roller and starting with my suspension and frame. Do the cases have trouble when you start making the bigger power? I know my raptor did and I had to install case supports Sent from my iPhone using Tapatalk It never hurts to upgrade a few things in that department but as far as the cases themselves they will be fine. The D shaped rubber engine dampers on the front and the rear of the motor, I'd at least use 4 of them instead of two (two up front, 2 in the back one on each side).

It's safe to assume there all at least 10 years old and very few people have ever changed them Quote Link to comment Share on other sites More sharing options...
rickybobby Posted June 1, 2016 Author Report Share Posted June 1, 2016 But I thought everyone used eBay? Don't worry I hate eBay I never buy anything from there. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

I always take for granted the fact that I just replace those things where most people wouldn't. Quote Link to comment Share on other sites More sharing options...
rickybobby Posted June 1, 2016 Author Report Share Posted June 1, 2016 Thanks a lot for the info everyone, I feel I'm going into this a lot more informed already. As soon as I find a roller I'm willing to pay for I will probably begin a build thread though it will be slow someone might enjoy it Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
rickybobby Posted June 1, 2016 Author Report Share Posted June 1, 2016 $6k plus for a full build is what you should expectThat's not as bad as I was thinking, thanks for the input Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted June 2, 2016 Report Share Posted June 2, 2016 421 serval. 80+ horses with a very rideable power. They were designed for the guys wanting power with out it being a drag motor. Cases will be fine and not need any major work as the 4mm crank will drop right in with out being trenched. The trans should be worked over while you're in there though. Do a pro mod, not an over ride. Upgrade the clutch with fresh components and a lock up as well. You could get by with really stiff springs, but it's no where near as nice to ride. Don't forget carbs, good pipes, reeds, and all the other odds and ends. Quote Link to comment Share on other sites More sharing options...

Do these servals run better on the In frame drag pipes also? I know the cub cylinders did Sent from my iPhone using Tapatalk Edited June 2, 2016 by rickybobby Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted June 2, 2016 Report Share Posted June 2, 2016 Yes, however they still make a good grunt right when you stab the throttle. Snipers, Shearers, CPI's, or Rockets. There is a dyno comparison in the Dyno section. The Serval is very similar to a cub, however they are cast with a bit more conservative port lay out to make the motor more friendly for riding other then drag racing.

locogato11283 Posted June 2, 2016 Report Share Posted June 2, 2016 An 800cc+ properly set up Raptor is going to walk any 421 or 465 serval and will give most 10mm Cubs a run for their money. Quote Link to comment Share on other sites More sharing options...

rickybobby Posted June 2, 2016 Author Report Share Posted June 2, 2016 Loco I know this, the classes are 2 stroke and four stroke divided, with a outlaw class that is both. I have real faith in my riding ability. Most of the places we are limited to dirt tires, and these guys can't keep they're front end down long enough to go straight. I just don't want to sink 10k into a 907 on alcohol, it's just not in my budget Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
ClaudeMachining Posted June 2, 2016 Report Share Posted June 2, 2016 Driveline lp top end can also do the job and it's cheaper than a Serval. Envoyé de mon GT-P5113 en utilisant Tapatalk Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted June 2, 2016 Report Share Posted June 2, 2016 I don't see you beating a ~100hp raptor with a 4/10mil serval if the raptor is set in right. They just out the power down better. My 521 serval is nasty in terms of power even though it is smooth and not violent. You looking at around $7k for a 10mil ported serval. Mine made 109/57 I think. Then there's suspension so you can turn the thing and get power to the ground. I started around $2500-$3000 for my 421 serval build when I started called builders. Decided to go 521 and I'm well over 10k. It adds up very very fast to do it right the first time. And I'm still not done. Quote Link to comment Share on other sites More sharing options...
