hi
im planning on putting a 4mm stroker crankshaft in my grizzly but it says bolt in ang ready to go with a stock piston but i have a wiseco high comp. oversized that makes the 686
does anyone in here have tried this crank or heard of someone that did it and works with the wiseco and does it give a good power gain
 

he has it multi posted. he should go to grizzhoppers site (site member) and look there as i do not know of a member on here that has tried that. mr sled has the bigbore on his grizzly but i do not know about the crank.
 
cant believe how slow the atv forum is compared to the sled forum,you can almost count the regular users on 1 hand,im on here year round and in the summer the sled section is busier than the atv one,weird
 
it is not my thumb that is itchy. more like my hand as i tend to use one of these more.

thanks. just put a gyrt silencer on it.

the xt is a bit of a sleeper now. just put some custom cams, ss valves, ss oversize head pipe and a new clutch. due to an oops with a cam bolt i am currently changeing the lower case. scared me a little when it lofted the front wheel and the clutch was slipping.
 
i cant get over how nice the WR is! i would love to have a yz450f supermoto converted someday.
 
i wish i had waited for this year as the wrx is all black in colour.

i would not have started the xt hop-up if yamaha had imported the wr450x/r, would not have bothered me if it was pink either as paint is cheap. ended up with the wrx as they had lost the head for my xt in cali. i was without my xt from april till mid august whitch is why i bought the wrx at the beginning of august. still managed to put 2000km on it before i put it away for the winter.
