Hey guys. guy brought me an 06 v star 1100
i've changed at least 2 dozen sprag clutches in everything from
suzukis, yamahas, triumphs to ducatis, and i've worked on lots of v stars, but i've never
put a sprag clutch ON a v star......... new territory for me.
mostly it's been tires, carbs, electrical, fork seals, blah blah type stuff.
long story short,
took the flywheel off. put a pin in the lower cam gear... replaced
the sprag clutch.... went to install it, and the cam flipped!
obviously, this completely sent the timing of the engine off... i
had no idea that i'd need to get the engine to tdc, etc before i started
this (otherwise i wouldn't have taken the job. it's cost me 14 hours
total for something that i charged 3 hours for including other issues
with aftermarket parts i had to "customize" to make fit. ( the new sprag clutch had to be sanded down on the outer diameter / beveled to fit flat onto the plate or the snap ring wouldn't fit. that cost me 2 hours on its own ( dont buy ebay parts. buy OEM) ... )
pulled right cover.
connected the lower dots.
front cam was 180 off.
turned the crank over till T matched the timing hole..
moved rear cam to connect the upper dot with mark on case
installed flywheel (a few steps between this with the rear gear and springs/dowels and key)
everything on the rear appeared to be 100% aligned as far as i could
tell. even with the tensioners in, they looked lined up in the rear.
once i turned the motor over, the FRONT looked like it may be a little
bit off, but, it was nearly impossible to crank the engine without the
valves and rockers n springs pushing the cam back down, blowing RIGHT past the mark and having to go back again and again and again, AND walking
from right to left right to left right to left constantly checking the
timing home trying to align it.
the front cylinder LOOKED like it shoooould be about right, but it has been an educated guess.
so... i did a cold comression test. 7 cranks, no oil in motor, 120 front 90 rear...
did again... same results. did again. same results. within a few psi... 10 cranks cold.. same exact results..
problem : i didn't do a compression test BEFORE i started, because
it wasn't part of the job. so i have no base line. it may be timed
right and just low compression due to no oil and having sat for probably
other problem is, it's been sitting, for... like i said, probably a
year. the gas smells horrible. guy that the guy bought it from says "2
months" but he's full of it. so.... even if i put fresh gas in it, it
WILL run like crap because the jets and passages are probably clogged. but.. i know the difference between a badly timed engine and bad carbs.. i just don't want to put it together before i know for sure it's timed right. ((( but nothing touches, so i'm not hitting pistons to valves ))
so... my question is..... if the rear cylinder is 1 tooth off on
the flywheel side, would it lose 30 psi compression? or would it be a
i dont want to re-assemble the entire bike and put oil in it, just to
have to tear it all back apart again. however, i suppose i could
always move the cam 1 tooth without having to pull the entire cover off
the sides......... right????????
any advice is greatly appreciated. this dude is supposed to be
picking the bike up saturday at some time.... probably more likely
if anyone has experience in these things, i would really love the assistance.
BTW admin : moderators, i had to answer the security question no less than 6 times to get it right... it kept asking if Vstar was a motorcycle. i kept saying yes and it kept kicking me out, so i said NO and it still kicked me out, then it asked what starts with V and ends with R and i did that a few more times. jeeeeezzzzz.... then there's the whole activation thing... :-/ that's a lot for a forum that i need to post 1 question to about a bike i don't own.. lol however, thanks for giving me a place TO post that question... that's the important part..
