CRANK!

Recommended Posts

I was out a few days ago and i think i took my crank out if i do have to replace it what kind should i look at???? I was driving along not even hard and the bike made a funny chug noice i shut it then later tried to kick it over to find it had seized when i got the bike home it would kick over but i haven't really tried starting it but when it did start to turn over it made the chug noice again!! Any ideas im open to them

 

 

Thankx

Jay

you wont know any thing till you open the motor up i could be a cracked piston.

 

if the crank is bad i would put a +4 stroker in. if you need a good used crank i will have one that i would be will ing to sell

No experience with siezed rod bearings on a banshee but had it happen to the wifes blaster. The motor definitly couldn't be turned over when it had just happend and just barely when it had cooled down.

 

You'll defintely know if it is your crank or not if you pull the cylinders and the rods are stiffer than hell to move back and forth, or are sloppy loose side to side, or if you cant easily turn the crank using yor hand on the kick start.

I've had two cranks go on me. The both went at low rpm's. If it's your crank you need to figure out if you want to go expensive... or really really expensive to fix it...lol

 

Tdr is know for banshee cranks and they are probably the cheapest.

 

350-400 for a crank

60-80 for a bore job

150-190 for a piston kit and gasket set

30 for a stock used head

30 for a seal kit.

 

If you want to go 4mm and do it right you have to get it ported

 

500 crank

200-500 porting

60-80 bore

150-190 piston kit and gasket set

190-210 (I think) for noss head (don't need to but highly suggested)

25 for a spacer plate (If you don't run the pistons into the head)

30 for a seal kit

300 for carbs and jets

100 for intakes

40 to mod the air filter sys or get pod filters

200 for reeds and reed cages (those can be done later)

 

So, if it's your crank you have a lot to think about. I can tell you that you'll get most of your power from the porting so pick a builder wisely if you go that route.

Rod, is right there is a lot more than just stroking it.. All the little odds and ends... If U R already ported and bigger carbs yes go w/stroker other wise U r looking to spend a lot of cash for a stroked crank..

I thought you a slim chance of existing porting being compatible with 4mm or more stroker? I looked into stroking on my last bike, and for some reason I remember something about the possibility of needing unported jugs also. ???

Correct.  Once ported for a stock stroke, you cannot re-port for

a 4mm or whatever.  Any attempts at such would result in

relatively poor performance.

Depends on the porting. My cyilinders were previously ported before my stroker. The were borderline for the stroker but they did work out. Depends on how much was originally cut from the cylinders. You're builder can tell you more though.
