Just a little teaser of my latest project.

[jon370r]

This is all you get. So far I have about $800 in this whole engine. Its a 350cc powervalve and uses a stock long rod crank. Thats all I'm going to tell you until its up and running.

[jon370r]

next

[jon370r]

another

[jon370r]

one more

[Aceman]

HOLY CHIT!! I hope we don't have to wait long to see the rest!:mad: :D I hope it does better than that last 350 cylinder you had, otherwise we'll never see it.:p

[my88r]

better get that built so we can see it

[Aceman]

You can say that again.:blah:

[blb515]

I have noticed you selling quite a bit of stuff on ebay and was wandering what was going on, those pictures clear it up a little I guess!!!

Looks good!!!

Keep us posted!

[250r4life]

whatever happened with that last 350 you had that you couldnt ever get to run right?

[jon370r]

This is just my test bed. When i get the bugs ironed out of this it will be resurected as a 401 stroker, and yes I have been clearing out alot of my stuff on Ebay I have collected over the years. Plus I bought a complete 350r from a guy I know who didn't ride it anymore and needed the money. I also put a long travel +3 Laeger T-pin front on my quad. I will tell you my 350 story when I get some time later. I work 3rd shift and I'm going to bed.

He's buying too. He picked up a new AC swinger skid for $25 that I had my eye on. I just happened to forget about the auction and it was over by the time I remembered.:rolleyes: Story of my life.:(

[86 Quad R]

[Meat]

[CorvetteZ06]

nice motor, good luck with uit. :cool:

[jon370r]

Sorry I'm a little tipsey, its fri night and I can't type or respond.

[jon370r]

I got the engine in and running today. Only put run a couple of heat cycles on it but sounds good.

[jon370r]

Also got a +3 long travel Leagers Protrax T-pin front suspension setup. Haven't got to try it out yet.

[CorvetteZ06]

wow, thats sweet!!! that t-pin front end is amazing. also, when did leagers make an aluminum frame??

[jon370r]

It's an LRD Attitude frame, like you didn't know that!

[Mcknight#5]

Thats cool. I know what cylinder that is. i wont say. but the piston that orginaly goes with that cylinder has a diffrent wrist pin size. and you said it uses the stock long rod crank. that head is a work of art to.thats just awsome.

[koh0001]

That's a sweet bike !! Let us know how that motor works out. You know us 2 smoke guys want a bigger motor....lol !!

hehe :cool: :D

[400exrider707]

Very cool:cool:

[fiveOnick]

Where and how did you come across a rotax setup that cheap. Also one thats only 350cc. All those I have seen are big drag motors, packard usually.

You seen this yet Jon

[atvmxr]

where'd you get those front tires????!!

My R came with Hoosier's like that, but when I went to order another set was told they discontinued the molding ( this was ~ 1996).....

[jon370r]

The Tires are made buy DURO and I have seen them in the Parts Unlimited catalog before. I bought these off Ebay used with the Wheels for $112.

This version of the motor is a 350 and it uses the same 77.94mm piston from a Niks 350 big bore. Here is a breakdown of my cost so far.

$125 Cylinder with powervalve
$ 35 77.94 mm piston new (I love ebay)
$230 250R engine in need new crank (did I mention I love Ebay)
- $140 Sold the stock cylinder, head and pistion
$40 good used long rod crank
$50 Fill weld the cases(add material to machine to accept the cylinder)
$180 Machine work to bolt the cylinder onto the base
$40 Custom .100 base space from Cometic
$140 head and dome
$80 various gaskets seals and bearings

Priceless My time to do all the detail work,make custom parts and assembly.

Total $1080 for a complete 350 PV engine

And the best part is for an additional $360 in parts This can be bumped up to a 401cc big bore. I have been doing this myself not really copying others that have done this before. I just wanted something different for riding and to see if I could do it. Once I get the bugs worked out I will be putting it together as a 401cc. I just didn't want to smoke a $260 4mm stroker crank and $120 piston on something I haven't tried out.

[TheLadiesMan]

got any pics of the case machine work? or just any pics a long the way? looks killer

[fiveOnick]

Well you have done a great job and I completely commend your effort its fantastic. I think I shall wait for the 314 sphinx to come out. Obviously if you have not already you can guess what the picture I posted is now.

[jon370r]

What make the 314 sphinx different from a Niks cylinder? I know it a different casting but the port layout looks to be the same. Won't it come down to how good a port job it has?

[fiveOnick]

This view doesnt look the same.

[jon370r]

Is it going to be a nickle plated bore? What type of powervalve will it use? Up to what size bore and stroke?

[fiveOnick]

Yep alum, no sleeve. I think 68,72,74, and one bigger like a 76 or around there. Another cylinder thats bigger will not be powervalve and will be available in larger displacements. I dont know any details on the vavle or stroke.

[beerock]

jon raise the clips on the shocks to lwoer the bike its too high.

good luck with the rotax setup.

get rid of them fornt tires lol im sure they push like a mofo
