I came across these on ebay, And it looks like the identical to my t-wolf, I need/want a-arms that have replaceable ball joints as I bent a b-joint on my t-wolf. What do you think? Anyone with a 2007 BB that can mesure for me?

I hate to toss money at it, Oil pump is good as I have checked it by removing the test port screw.

Should I make a new thread as this is now not only oil out the breather problem?

Ok, New problem, It seems to be running wayyy to hot, Its melting the o-rings on the valve covers and starting to melt the plastic on the oil dipstick >_> Its also now burning oil big time when its hot, I am guessing its due to the oil thinning? Or it blew the oilring out from overheating

Also, Heres the plug

Weird line around it?

Oil leak from where? The cam cover is tight, And oring is good (Checked it when I redid the valves)

Sorry for the bad pics, Samsung Galaxy was taking good pics until i scratched the lens

And the exhaust has leaks (Around where the header meets the muffler

I was thinking of putting some type of collector inline with the breather hose? To collect the oil and let it run back down?

Well, For the time being I guess I am going to have to run it as is, As its my main transportation and I got no money to purchase a leakdown tester

Only one vent line, And yes its clear as it has pressure out it when engine is running. Its strange that this engine has no filter or valve between the vent and airbox

Since I have had this Yamaha Timberwolf it has had the problem of blowing oil out the breather, Also if I am running it down a road and look back I can smell oil, So I assume its burning it as well, Plug is a light brown in color. Goes through about a quart in about 7 hours of run time, Some of which ends up in the breather box, How can I remedy this? It has good compression (Rated is 128PSI) 125PSI. And starts without problem with the electric start. I am out of ideas and the cost of oil is killing me.

I know a somewhat diff beast, But its been around 1C and mines been starting right up without the choke, Amazed me

Looks more like a timberwolf, Due to the rear fenders

Only has one vent line off the crankcase, and it does not seem to have a valve so its constantly getting pressure out it, I have a feeling thats where some of the oil in the air box is coming from,

Can I ask the reason behind changing the oil so often? A car goes thousands of miles before a change, A garden tractor goes about 20 hours or every season for changes?

This is a line of ATV's thats been carried for over 10 years, Most the same frame/engine correct? I know this engine design is also used in other atv's, Not sure which ones though, There must be some mod's that people have done? Even mineut changes, Post em here! Would like to get ideas for mine and see what other people have done.

^ That gets a little pricey after a while though no? How many hours do you ride for at a time?

Its a 1992, I know for a fact its not the orig jug/rings as I know the previous owner, It just had a valve job done, its got 10W30 in it, Changed the oil 5 hours ago of run time

Noticed it this morning, Was -1 out, Started it with choke half way open, Fired right up second crank via electric starter. Shed was filling with not exhaust but oil/smoke, thought nothing of it at the time, Fast forward to later today, Started it up after washing it, And got a big puff of smoke from the bike, Checked the oil, Sure enough was down about half a quart, Opened air box, Oil sitting in the bottom of it (could have been from the prefilter though but there was an oilish trail from the intake tube which the breather connects to) Breather tube has milky white oil (I know it means water) Any ideas or help would be apreachiated, It has great compression which strikes me as odd considering its used half a quart of oil in about 5 hours run time (Have a hour meter)
