Recommended Posts

i just bought a brand new 06 banshee with the toomey t6 kit and i havent got the crank welded and trued but what are the chances of the crank messing up, i trail ride on moreopen trails than anything, and its usually middle of 4th on the trails, should i get the crank welded or not

 

 

I am running porting and a lot more and also do a lot of hill shooting and have not had any issues with my stock crank and im not really too nice to it. A welded crank is not a bad idea but with what you have it is not a manditory mod. In my case its just a timebomb waiting to go. :ohmy:

well its brand new with jsut the break in time on it, and i dont drive it hard at all really, and i have a 3 year warrenty on it too, if something went wrong and the looked at the crank and saw it was welded would that void warrenty

 

leave it as is. if you got a warranty and blow it up between the time it expires just take it back and dont worry about it. if it does it AFTER your warranty is up, then get it done. why spend money if you dont have to?

The basic rule is: port it, weld it. Bolt-ons won't usually make enough power to kill a crank although I'm sure it's happened. Keep in mind that warranty is only as good as the company behind it. Many insurers will fight to keep from paying warranty claims and will demand service records and etc. Is the factory giving warranty, or is it a shyster dealership?

im sorry its a 1 year warrenty, and its from the stealer ship

Good luck if something with the warranty if something does go. I've experienced hardship with warranty companies. Also you may want to check your paperwork. I have bought a few 2-strokes brand new, they all came with a warranty and I was offered the extended, but neither would cover a 2-stroke motor. Especialy with any mods.But i aggree, with your mods you should have no problem with the strength of your crank.

dealer warranty are bs. i had a 6 month warranty on my banshee and i bought it brand new. after 5 hours of riding,

i went to change the oil and the drain plug was tighter than a 12 year old

back injury.

i ended up stripping the drain bolt's 6 sides and also messing up my socket. i took it to the dealer, they wouldnt drill out the plug, or give me a new one. they wants $45/hour labour to drill and tap the hole, and $20 somthing for a new drain plug. they claimed i used an adjustable wrench on it. well how would they know because they were not in my garage with me!

 

i ended up using a pipe wrench on it and i got it out, man it was in there tight. not i got a nedoium plug off ebay for $12 and its got a rubber gasket so i install it just a hair tighter than figer tight.

 

the short story is that dealers suck and look for ways to weasel out of warranty work.

NO to mention, I'd check if it still is under warranty due to the fact you have aftermarket pipes...unless the stealership put 'em on for you.

 

You'll be fine....

 

I've heard of bone stock motor's popping the crank, but those cases are very, very few and far between. Once you start playing with porting and/or compression, it's probably a real good idea!

(And of course, if you're gonna take the crank out, might as well get it ported....and so the sickness begins..lol)

iv had great luck with non welded stock cranks but welding never hurts them if you ever bump up compression or port the thing concider welding it but until then just enjoy it

 

What usually occurs when a crank decides to give? Does it just spin a bearing and mind it it's own business, or does it do worse, like throw a rod?
