going to get it tuesday.
cant wait.

my questions

is it reliable?

the guy says the clutch slips a little at the very top of 6th.

so i guess i might put a clutch in.

would the clutch need to be a high performance clutch?

if so what is cheap and good.

it has a YFZ muffler on it, 430 or 446 stroker [he isnt really sure which] newer tires, a bunch of goodies.

 

I hope like hell that has an oil cooler with the stroker or that motors life is going to be very short.

 

Definately need performance clutches. I ran Curtis Sparks clutches for a 660 Raptor in mine, and they seemed to last forever. Just make sure you use motor oil that is designed for MOTORCYCLES WITH WET CLUTCHES, or the clutches will slip bad!

If I were you I would try to find out exactly which stroker kit you have in there and who made it. It will make life easier if you need parts later. It would probably be from FST (fourstroketech.net). If it doesn't wheelie in 4th gear by just jabbing the throttle, I would question if it really has a stroker or not.

 

how much is a performance clutch?

is it like a clutch kit? i found them for like 100 bucks.

but whats an oil cooler and is it expensive.

btw how can i find out which company made it and what kit it is?

the guy isnt sure what company but he says its a 435 or 446 and i think FST is the only person that makes those.

 

I didn't think my old warrior I had a few years back had six gears if I remember rite it had 5 as for the clutch kit you can go with a barnett dirt digger they are pretty good or just go stock plates with heavy clutch springs. As for the motor that is a pretty big bore and stroke for that little 350 you should definantly run a oil cooler if possible and make sure you ask him what kind of fuel to run in the bike becouse most motors like that will be running race fuel and it is very expensive and if you don't run it your bike will burn up from lean detonation.
As for reliability probably not that reliable. The more you pump a motor the less reliable they are allot funner but less reliable so if your not good at turning wrenches I would probably pass on the bike and get a stock one with a pipe and jet kit and spend more time riding and less time wrenching.

 

i pretty much cant back out now. if i have to run race fuel that will suck really bad.
ill have to call him and ask if he does.

where can i get an oil cooler!?

edit: i just called FST the guy said he would recommend an oil cooler on even a stock one. lol so ill ad that to my xmas list, and he said buying a full clutch isnt required, i can just buy heavy duty springs.

EDIT #2: more pics. some closeups and such.

 

You shouldn't need race fuel with that setup as far as I am aware it doesn't use that high of a compression. The 435/446 stroker kits are very reliable, as long as you have an oil cooler. Micky at FST sells the oil cooler kit and I think it is around $100

 

yeah i called them, oil coolers are 95$.

so , so far my list for this thing on xmas is as follows.

oil cooler kit
tougher clutch springs [guy at FST said thats all ill need]
New vapor tach and speedo
"new" nerfs. [have a set of old ones, painting, new nets]

sound good?

 

I would really go ahead and replace the friction plates at least while you have the clutch apart. Micky swears by OEM Yamaha plates with just HD springs on his stroker motors.

 

if he swears by them and he is an engine builder then why would i change them?
