Maintenance & Technical > KX500 Original
Need HELP seized
Ims Roll:
lets start from the beginning, i bought a 2001 kx 500 about 3 months back, (my first 500) i rode it around the block in Reno and it felt llike it had all the power in the world and handled pretty good (me being a HUGE guy really helps) but when i brought it back to Las Vegas i ran it down the street and seized it up, im thinking oh i forgot to jet it. oh well least it will have a fresh top end now, it has a 52 pilot and a 160 main at about 2000ft above sea, needless to say it was a bit lean. so i rebuilt it about a month ago. new hone, piston, rings, wrist pin, needle bearings and gasket kit. i finially get the bike back and together and suddenly the suspension is so bad that it feels like riding a boat even on the street... i tried to fill with nitrogen but no help... soooooo
Ims Roll:
so i finially get it back together last weekend, new suspension (gold valves race tech springs all new seals n bushing n rubber) as well as a brand new top end. well i take it for a ride and while it's running it is spitting water out of the overflow... so i bleed the air out over night and it stops. so i assume im good. ride it down the rode do a spark plug test and i have it running good with a charcoal grey colored plug. yummy right. so the following morning i take it down to my favorite test area. a whooped up road full of g out's and other fun things to test desert stuff on. well it's about ehh 4 or 5 miles long. on the way back she seizes up on me again. not even 8 miles into the ride (not running it very hard, and yes i did break it in properly) so i bring it back tear it apart and first think to myself, water pump? so i pull that apart and everything looks to be up and running fine. could it be the crank seals are leaking by and leaning the piston out>? and if so wouldnt that have made my plug test lean? any help pleaseeeeeeee????
Motorrad:
What was jetting the 2nd time?
Float hight?
How was tranny oil level after 2nd stick? Oddly low?
cbrfrenzie:
What piston and PTW clearance did you run with the rebuild? I know the forged pistons need a little extra due to their thermal coefficient.
Ims Roll:
my jetting the second time was 58 pilot 165 main and about 2 turns out on air/fuel screw. float hight (nothing sientific) was pretty high i couldnt get the float bowl to stop leaking so i had to push it as far up as i could get it. the oil was full and looked great not milky or brown. i am cracking into the top end tonight to see what all is dead. i bealive it was a wisco but i would have to check when i'm home but i had steve rezimwikky do the hone and order everything i just slapped it together, but he used to build stock car motors for my father in the 80's and 90's. i have had a few people tell me k5's can only be sleved not honned, is this true?
