Sold

I deleted some PMs, John so you can either try it again or feel free to call/text 608-214-1110.

I couldn't even guess what the shipping costs would be to send a banshee across the world. And to be honest, (nothing against you) but I feel uncomfortable shipping a high dollar item like this to a different country. I got screwed out of $2000 worth of Diesel performance parts recently so I'm now in a "cover your ass" state of mind! lol And I REALLY don't feel comfortable shipping it to a 3rd world hole called Oregon where electric dirtbikes race around at 12mph.

False.... the 5r110 will handle about 70hp more than an Allison 1000 of the same era. As for the new transmissions, if anyone is familiar with H&S performance and their live dyno session "BREAKING POINT" you'll see that the stock Ford 6r140 transmission "slipped" at 884rwhp and 1660ft/lbs where as the new Allison (also stock) slipped at 568rwhp. While this sample size is extremely small, its hard to argue that every other transmission is FAR behind an Allison when the Ford 6r140 held 316 hp more on the same dyno. However, the Allison 1000 has a big aftermarket support so they can be "built" bulletproof. Best advice I can give to anyone considering owning a diesel is the advice that was given to me... drive all three brands with different options and choose which truck YOU like the most. But make sure you have a little money left over because I've seen 1 ford, 1 gmc, and 1 dodge sitting next to each other in a 3 bay diesel performance shop all getting head gaskets at the same time. I should have snapped a picture.

$3000? Maybe I should look into parting it out?

Its easy to get caught up in the power they all have to offer (all three brands) but fully expect and set aside some money for EXPENSIVE repairs. I learned very quick once I bought my diesel that they ALL break and they ALL cost a lot to fix when you start modifying or tuning them hot. If your sole purpose is work, any of the big three will do but be aware that even stock cummins are hard on the 48RE autos so I would advise a manual trans.

I think this crank failure scenario is highly unlikely. If you had huge heavy pistons swinging around making large-motor horsepower spinning at a speed only drag ported cyls could produce.... then forged or billet cranks might fail. Unless the crank has a pre-existing condition causing it to fail, I highly doubt a 10mm serval will destroy one. Build it, ride it, and have fun!

There ya go. You answered your own question. Until you run racing pistons and modifid stock pipes along with an aftermarket powerband you'll never even touch 150mph.

I run a 421 serval. For what I ride it has a sweet "forgiving" powerband. The powerband comes on predictably and gently so I generally hook well. I was debating between the serval and a cub when I was in the market (I ride hair scrambles and technical stuff as well as open land f'n around). One factor I liked about the serval is I could always have a builder port it to stock cub port timings or any cub port job imaginable but I couldn't add metal to a cub to tame it down into a serval's powerband. A lot of guys run some wicked fast setups and Im sure I'd get spanked as my banshee isn't set up for drag racing.... however... I've not ever seen a cub cylinder amonst the groups I ride in. Its mostly shitty banshees and "monster" YFZs lol. And yes, the serval completely embarasses them in a heads up grudge race.

Have you thought about a 10mm serval? You can always have it ported to ANY cub spec later on if you wish.

Yes to the title. I haven't a clue what is reasonable for the bike minus engine. I'll have to do some research. PM me if you're serious. We might be able to work something out.

Second option is to part out the +2 swingarm with honda style carrier, a-arms, shocks, all the other misc. stuff and keep the serval motor until I come across a TRX/YFZ450 chassis. Or go back to a stock length swinger and some long travel arms/shocks up front. But I've got way too many projects so I'll let the sale go a little longer before I get something up my bunghole and take on another project. lol

$3100

It'll make more of a noticable difference on a modified motor. Stock cages with aftermarket petals is sufficient for a relatively stock machine. Porting is the next bang-for-buck step.

Its a stock transmission that has been modified to shift smoother/more consistent.

Plus the 450s come with a heated seat to keep your vagina warm. CR500=man bike

I am Japanese. Y U make funa me?

This isn't american made. Japanese nuts are much smaller and usually without hair.

I've already got a diesel truck that I purchased to tow the camper and trailer.... that turned into a toy, too. lol

I can only guess based on other dyno graphs. When I built it, the 421 serval was supposed to be around 80hp/50ft/lbs with a wide torque curve. I do know with the rocket pipes the powerband comes on at 5200-5300rpm and signs off around 9700rpm. Mind you, my riding group consists of stock cyl/piped/jetted banshees (some ported) and piped/jetted 450s and 700 raptors... but I embarrass them in the open. lol Who knows, I may keep it for shiggles. Or part out the frame/suspension and fit the motor into a YFZ/TRX chassis!?!? Only people interested are lowballers and kids with no money. I got a text from someone saying "I'll give you an even 2 grand for your quad and pick it up saturday in the A.M." Someone else said they could give me $1000 now to take it home and make payments every month until the asking price was met.

What... the.... fuck

Thanks! I've already gotten offered a snowmobile and a honda civic that "I could sell and make more".... oh the fun. I ask a fair price in hopes that a buyer makes a fair deal. The first year I built the 421 serval and new suspension I surprised a lot of raptors and 450s! But riding places dried up (or became regulated) and friends sold their machines. Thinking about building a quick boat... hmmm. Anyway, title in hand!

I feel bad for Zilla. He can build a thousand bridges but no one will ever call him a "bridge builder".... but ya suck one dick and everyone calls you a "cock sucker".

Looking at the dirty pictures, you play in mud and grit. The heim joints usually wear considerably quick in these conditions so you may want to thread some ball joints in place. Also, you REALLY should throw some cotter pins in your upper and lower joint studs. The arms are adjustable, so tuning the caster, camber, and toe in for your riding style will help the performance.
