Reply to Opinions on Cranks. OEM vs. Aftermarket 5/21/2020 8:45 PM

Basically, OP if you don’t have the correct tooling to measure runout... don’t use a screwdriver as “.005” is an absurd amount of runout in a single crank (any pressed crank honestly)... just take it to a machine shop they’ll be able to check it in a ... more »

If you have a core have it rebuilt with an OEM or equivalent rod (Pro-x, Wossner, etc) I’d recommend Crankworks they do great work (sometimes they even have rebuilt cranks for sale)... If not, I’ve run plenty of hot rods cranks (in stock applications) ... more »

I’ve always used wheel acid to clean raw pipes, and just coat/ wipe them with wd-40 after washing/ riding to prevent surface rust...

Two methods to use in combination... assemble the head using some light dummy springs... install on the engine without a head gasket, set cam timing...then place a dial indicator on top of the valve bucket and rotate the engine around... as you rotate ... more »

If the timing marks are on I would suggest a Possible spun Cam Gear... Stock cam and valves? also is the piston in the correct direction (not doubting your abilities just eliminating possibilities)...

ProX makes great products... I’ve seen wiseco cranks fail too many times to ever recommend them as a product... From big end bearings failing in a matter of hours, to wrist pin bushing failures, to rods breaking... I’m not sure what the issue is... but ... more »

If it’s brand new most cylinders are stamped with the bore size on them

Reply to Cylinder bore measuring? 4/30/2020 11:30 AM

I agree with this as well snap gauges are good for getting a rough measurement... not very accurate when getting down into the ten thousandths...

Reply to Any tips to do bottom end rebuild rm125? 4/30/2020 11:18 AM

Not trying to be negative but take the wiseco crank and replace it with a better crank preferably an oem unit ( new or rebuilt) or even a hot rods assembly ... not too many tips other than get The correct flywheel puller, and a case splitter...

Reply to Cylinder bore measuring? 4/30/2020 11:10 AM

Measure in several different locations... one location of the bore won’t tell you the true shape of your bore... I take 3 initial measurements top, middle (This measurement can be hard on two strokes because of the transfer ports) and bottom; Then 3 ... more »

Reply to Balancing crank and oem or Wossner rod ?? 4/23/2020 11:35 PM

Wossner makes an excellent rod... trueness is more important than balance... However, if you have the spare money or time you can change the balance factor... I wouldn’t necessarily say you will see a reduction in vibration, but rather a change in the ... more »

More oil in the exhaust would leave me to believe it’s a low compression issue, or maybe a possible wet side crankseal leak... how did the bore look/ measure

Did the problem begin Only after you changed the ring?

Reply to Ignition Issue 4/19/2020 10:43 AM

Little confused here as the coil has both primary and secondary windings... if you tested the coil per procedure in the manual and it was within spec I’d suggest your problem lies elsewhere... start simple disconnect the kill switch... then proceed to ... more »

Reply to 2004RM Kill switch 4/18/2020 12:36 AM

Black and White is more than like chassis ground... Take an ohm meter and check continuity to ground... However, in all reality it doesn’t matter wire direction the switch is just completing a one wire circuit short circuit to ground when depressed... ... more »

Yes, start there

Reply to Ktm 250sxf jumping into neutral 4/12/2020 6:58 PM

Worn shift dogs are another possibility (which if left alone long enough normally leads to a bent shift fork)... I’d start by checking the shift detent and shift star...

It’s for flywheel to cover clearance... odds are you have a flywheel weight on your bike...
