    I had read somewhere that it needed the back pressure to run properly is all.

    Does anyone know if a R&D Flex Jet Fuel Mixture Screw will work on a Mikuni TM40? I'm assuming it will but I figured one of y'all would know for sure.

    Evening! I just got done rebuilding my 650R and torqued the head to 49 ft/lbs no problem. I first torqued to 30 pounds and then went to 49.

    just got done installing new bearings in some of the rear linkages. advice: don't let the shock linkage sit in the 10 degree garage for hours before you try to press in the bearings or install the oil/grease seals, it won't work. thankfully i'm smart enough to know my error right away instead of forcing things. freeze the bearings and heat or warm up the linkage. that's all.

    edit: oh ya, anybody have any recent reviews on the tusk brand clutch kit? recent mistakes have taken a toll on my funds.

    i believe I replaced mine when I did it. I didn't want to take that chance. However, they are some pretty tough bolts, I think you would be more likely to pull out threads than snap a bolt.

    Not so scary now that we have Time-serts. :clap They are a whole lot nicer to use than the heli-coils.

    if the bolts are still in the case, why not leave them? if you are replacing them because you are worried the case threads will let go, then the bolts are not the issue, right? steel bolts vs aluminum case. bolts will win.

    I believe there is some stretch to the studs once they are torqued, but I honestly don't know the correct protocol for replacing and if it matters. After dumping $1k (or whatever) in to the motor why not?

    Sorry i worded this post wrong. I was concerned about snapping the studs not pulling the threads out of the case.

    Speaking of time serts. Both of my chain adjusters were rusted and ruined from the previous owner, so I used time certs. Now its steel on steel (with plenty of grease + anti-sieze so way less of a chance of rust than aluminium and steel.

    So far they are holding up great and are overall much better than the other methods to repair the adjusters.

    I dont understand why Honda and other companies have the chain adjusters designed so poorly. They know these bikes are going to be slogged through water and mud. The bolts will rust.

    I am the proud owner of a new-to-me 650R

    My local KTM dealer took it on a trade and blew it out to me on consignment. Cheap cheap!

    It's got the factory skid plate (which I like), Edelbrock, big tank, ricky stator, power up and a full pro circuit system. The headlight, although ugly, is blazingly bright. It does appear to have been washed with purple power (much tarnishing of the aluminum finishes) and the rear chain slider is gone, but it starts first kick every time. I'm gonna love this bike.

    Spoke with a fella at MX Tech Suspension in Illinois today.

    http://www.mx-tech.com/

    Seemed to know the R well and says it can be set up for my riding style which includes normal trail riding and some moderate m/x-jumps. About 10-15 feet in height.

    I want to get rid of the full compression when I flat land a jump from time to time.

    $800 for full rebuild of all three parts, new fork springs and new valves on forks and rear shock.

    Is this the going rate for a service and set up as I have described?

    Any experience with this shop?

    Any recommendations on other shops?

    All ears.....

In my neck of the woods we have 3 feet of the white curse on the ground with daytime temps of -20. Biking season here usualy starts in mid to last week in april and ends in the middle of october. :cry

    new Wiseco STD bore 10:1 piston question. with the rings that it came with, the end gap for the top ring and the second ring are the same coming in at .014in. is this normal? i would assume they would have all that pre-determined, but i guess not. next question...what is the best way to file the second ring down to widen the gap?

    I used a flat file to set my ring gaps.
