Did you have the power valve linkage cover off the cylinder? There was a common mod to install a "bushing" over the power valve stopper pin to limit the closing point. Many times the bushing can come loose and fall off ...🤷

A lifetime ago i used to frequent the ISDE and watching guys rip full size 80's for 5 days and a moto, that was impressive. The top guys in the 125 class would beat the life out of those bikes,also impressive. Nothing kills any bike faster than pure ... more »

I feel the same way about the 99 YZ125. Truly amazing motorcycle.

There should be lubricating holes on the exhaust skirt of that piston....being a wiseco. It even shows where and how to locate the holes in the box the piston came in. It may be low hours but it has definitely been dusted. Might want to look into a better ... more »

Just for a quick and easy experiment instead of changing the base valve shim stack ...throw in some 7wt oil or ATF. If that feels harsh and jarring then look closer at your mid valve float height. Reduce float height by .5 mm will help more with low ... more »

I've stayed at King's Inn for the past few years. You can park your vehicle there and walk to the stadium.

I got this in my home town on the west coast of canada. These bikes and all years of the 250's and 350"s were really popular in the western provinces with hot beds on vancouver island and rural vancouver. i paid $500 cdn for this one. In 01 i gave away ... more »

Im also an old trials kid and have been on the look out for one of these for quite some time. Due to this ones completeness and general condition Im hesitant to ride it too much. I'll be happy with a complete clean and detail and the odd plunk around ... more »

Picked this up over the weekend 😁

That sounds fantastic. 😃

I find it a bit sad that any builder would turn you down for the work on this engine. Very much like you said there isn't much to these motors. Armed with a couple of decent pullers (flywheel & case splitter) a person can have them apart in well ... more »

ah..yes....the old "broken intake skirt" dilemma...Its a common issue with top ends that went a bit too far out of tolerance and got pushed hard. Many times the larger bits n pieces of the piston get clobbered by the rod at bottom dead center and conveniently ... more »

Also look for cracks around the upper shock mount and linkage mounts. The 94 250's were known for having these issues.

The system is pretty simple. It consists of a stator or source coil ( think alternator) with a magnetic flywheel (#8), an external pick up coil (pulse generator)(#8) a CDI unit ( brain box)(#7) and a two sided high tension coil ( primary and ... more »

There wasn't much really wrong with those engines. Good maintenance practices in regards to keeping the hpp valves super clean and sliding smoothly is important. Exhaust pipe sealing in the cylinder is a bit of a pain and needs constant attention. The ... more »

06 ranger camping set up....

This little bastard had just over 900,000km on it before I had to let it go. Still ran pretty good.

I'm an RC guy when not out on my bikes so...I watch quite a bit of RC races on YouTube from around the world. I'm keen on sidecar racing as well and follow the British championship pretty closely. I also follow all the Enduro disciplines locally and ... more »
