thats OK nayruf , this is what I meant, now this is the piston for a DT175C...clearly the holes arent as long as the 175MX...I know your bike runs well and I'm not suggesting for one minute (despite my little joke) that you shoud change it but just thought I'd point it out to you...food for thought as it were For Twinshock http://www.ebay.com/...6-/350456956387 and for DT175MX http://www.ebay.com/itm/Yamaha-DT175-MX175-2n5-11635-00-PISTON-2n5-11610-10-ring-0-25-NOS-OEM-NEW-/370643961150?pt=Motorcycles_Parts_Accessories&hash=item564c1a053e&vxp=mtr

yeah I thought you'd laugh at that...however I thought all the twinshocks had the rounded intakes in the piston because the pistons are different part# and the model guide shows it to be so...Honest guvnor, I dont make stuff up

What year is your bike?

I would go as far as to say that yours is wrong also nayruf, yours looks like a 175MX piston...perhaps you two should do a swap

Assuming the fork legs are not bent Perhaps the forks are twisted in the yokes Remove the front mudguard (for vision) Slacken the RH axel clamp nuts Slacken but leave nipped the four bottom yoke clamp bolts Slacken the three top yoke clamp bolts Enlist a friend to hold the wheel between their legs Twist the handlebar until the wheel appears perpendicular to the handlebar Hopefully this has moved out the RH leg a little? Torque everything back up to spec Forks Upper yoke pinch bolts 18 Steering bolt 43 Lower yoke pinch bolts 14.5 Torque settings in lbf/ft

The RH fork just clamps around a split sleeve on the axle, you should tighten the two clamp nuts up after the spindle nut is tightened and not before...did you do this Sam?

Err actually the free coffee and bacon butty van has a collection box on it, voluntary of course

heated grips if you're gonna continue with that hefty commute over the pennines! bippo;)

you could try the labour saving way to clean out the crankcase, repeated filling / shaking about and emptying of the case with petrol using a fresh charge each time, you'll get a feeling if the crank bearings are clean by rotating the crank by hand while holding the con-rod, It'll be an engine out job of course. Most of the damaged piston will have exited via the exhaust. so what size jet is fitted right now? I'm thinking a 250 will be about right. Take the reed assy aout and make sure thats clean too

mastiff to check the fork legs roll them along a piece of plate glass and check you cannot slide a feeler gauge between the glass and the leg at various points

Thats the wrong piston by the way, it looks like one from the twinshock bike

DT175 and DTR125 are completely different, the DTR is a much more up-to-date specification with its water cooling and crankcase induction. It's quite a good performer in its own right fitting an 170 athena will improve that performance further but would you will have extra insurance costs due to the performance enhancement? and I assume you arent on 'L' plates?

me too bippo I havent seen any sign of this years sally army run so I've emailed them to ask

Dohh there needs to some slack in the cable of course!

well then assuming you have a little slack in the clutch cable... 1: your clutch needs adjusting (see the manual) or 2: your friction plates are worn out and need replacing hopefully 1:

I think possibly the Haynes book is wrong there myself what I think is that the pipe from the original exhaust connected to the airbox...you will see the boost bottle (YEIS) has only one connection and that is to the top of the rubber inlet manifold...confirm?

yeah fair enough, It's just that I've never heard of the athena exhaust but I am familiar with their big bore kits, There is no connection from the stock exhaust to the YEIS (Boost Bottle) is there

Greetings Consmos and , the DTRE is a cracking bike lets up we can get her fixed up and buzzing again eh

whats the athena connection? usually folks fit DEP exhausts, do athena make one then?

ahh disconnect the battery jayda and charge it up every month or so, or that'll be more expense next spring! is it carburated or FI

Thats a serious case of running lean isnt it!!! whats this Athena kit isnt it an oversized 170cc barrel and head? you mention expansion tank several times...do you mean expansion pipe aka exhaust? see my signature line

dont break the cluster...just drill the head....and not the tank

Have you seen this Mastiff? http://www.ebay.co.uk/itm/Yamaha-RD-125-Front-Wheel-RD125-/200627475865
