Gangus,
Notice the replate instructions I gave in the second photo, "crack not welded as instructed".
If you weld up this crack at time of replate it will only quickly crack again with...

It pains me to sell these as I bought them brand new and only ever used for about 5-8 pulls on the dyno before I prematurely stopped the development my 5KE. Sadly that's all they have been used and...

Purchased brand new from Japan in 2009, this cylinder has had little use from new and has been replated once only in 2010. No welding repair just simple replate to the cylinder, not used since....

Or fit your very own interface plugs in between, this way you can easily 'plug and play' between any ignition of choice into your loom within seconds.....just have your base advance software settings...

The problem in the image below was a dodgy kill switch on an RS250.
If the logger shows jaggered lines for RPM then there is no spark, not weak spark, fuel or engine setup.
Just saying...........

If it has a engine kill switch fitted, my money is on that.
By pass the kill switch, I'm sure all will be good after that.

Check the barrel shaped condenser is plugged into the loom. (green/red wire) Sounds like the stator can't provide enough power to run the PCM at high power surge / RPM due to a missing...

I've seen a couple of cases recently where some near new 5KE pistons have broken it's crown a piece about 1/8 of it's crown starting from one side of where the ring pin locating dowel is. It's as if...

Thanks Vince.
I've never had a tab break off but if you seen this happen due to fatique over time, I better also be careful in future. I normally have a tendancy to over tighten and/or re-tigthen...

I think that you did not mesh in the inner centre gear that drives the oil pump gear by turning the clutch basket/primary drive gear as your putting the cover on. This means that the side cover looks...

I was just working on a 4DP engine this morning and it has cast on the cases between the top reed block and barrel 3XV-02, however where the engine serial number is located on the cases above the...

I can't read Japanese and did not understand the sloped line for powerjet transistion so I logged my PJ's for the +2003 TZ250 ignition with kit setup.

I logged both top and bottom powerjets at...

3XV01 = 1991 TZR250R
This is a street bike, not a TZ250.

All TZ's from about 93 onwards till today has the wire Black/white wire.
If you short this wire to ground it will turn off the engine. This is where Yamaha recommend you put an aftermarket...

5KE has an extra steel and lining over the 4TW/4DP.
This means the basket and hub have to be made longer.
The 5KE springs are different also.
5KE uses 5 steels, 2 outers and 4 inner linnings...

Hi Neil,
What does the bearing sound like when you spin it on the drive side? Is it noisey when comparing to the clutch side bearing?
The drive side bearing only has 1 oiling hole compared to the...
