    Okay used Coffee's vid and everything is going pretty easy... Just gonna ask a stupid Q..


    TE 250 specs
    Intake 10 -15MM

    My measure: 15 easy and I mean real easy just a little drag

    Exhaust 15 - 20

    My measure 15 easy, 17 if I force it, 20 no way...


    Question1

    Is it Ok for the intake to be a real easy 15 ? should I put a bigger shim to make it tighter ? I know this is stupid...


    Question 2

    for the exhaust.. am I shooting for 20 ? should I be happy that it is on the smaller end of the scale ? should I go for a smaller shim ?



    Thanks for entertaining the Neighborhood idiot's questions......

    I believe the shims only come in 0.05mm increments. So if it is easy 0.15mm and it is changed to the next size then it could be an easy 0.10mm i.e a 0.12 would be the gap in theory.

    I go for closest to the middle but that is not always possible unless the shims are sanded.


    Honestly I think you are close enough for the time being, these are overbuilt valve systems compared to other brands.

    I think your probably right.... I'm fixating on the exhaust though

    Spec is .15-.20

    and it's a real easy .15 and a tiiiiiiight .178 so you wouldn't worry about it though ?

    It sounds like that is set correctly to me. If you changed to the next size you would be easy 0.20mm and tight 0.228 - right?

    .178 - .15 = .028

    .028 + .20 = .228... yeah, think that is how the math works out.

    Your right...

    .228 would be too loose out of spec... I'm just being ridiculous....

    Thanks for the help !!! :)

    You are not being ridiculous and no question is silly.

    There is probably a reason they specify a 0.05mm range, cause that is how far apart the shims are in the shim kits. That is my guess at least.

    I appreciate it...

    Thanks for helping me out... Still have the 250 and still loving it at 119 hours of riding (mostly dropping it in the idaho mtns..) went ahead and put a rekluse z-start on it , removed the clutch and am now running the Left hand rear break... It's like cheating I tell ya... I'm cleaning things I have no business doing...

    but it's still a 250 so you better be in the right gear.. so I'm considering a 300 kit to remove that impediment.... along with any clutch dancing skills I ever had... :D

    Was also wondering about your leg ? last time I spoke with you, you were still post op...

    Kelly at Motorsportz described how he sanded his down using a tire gauge to hold it. The post is either here or the other place. Just leaving Mammoth or I'd look it up for you.

    Snowed here. Took a ride on a dirt and paved road till I hit some ice. Luckily I found some dry spot to turn around....treacherous at idle speed even....
