KX Guru Racing

i have been neglecting this project and page, shame on me. last time i laid a spanner on the bike was late july. and it wont be seeing another this year i expect. too many other non bike things to do.

however i have been researching the symptoms that the bike displayed and i think a lot of the ...

I have it all already, I've been at this project for so long it's given me time to do thing like buying the cams, I just waited till one then another came up on eBay. I ordered the 1mm oversize valves from a company called Manley in the US. Then I got seat cutters and have already fitted them to the ...

It could be 43mm. I tried a OEM gasket but it did not sit on well with the manifold, I ended up making one out of copper which seems to be working out ok. What is probably the best thing to do is open out the exhaust port a bit. Perhaps not right away but at some time. And anyway a manifold will ...

The turbo came in the post, it is bigger, most importantly it is much bigger inside.

The other thing I was hoping for a result on was the lack of restriction on the turbine entry.

That's a coal burner, should do better than that

I've ordered a new old stock gt2256 hopefully the turbine housing will handle the exhaust ok, well I think just off the cuff, it will be ok. There is a company who turbo bikes for snowtracks that put 2256s on Ktm/crf450s and the like so I think it will be good, well I guess it still could be too ...

That was one of the things that was going through my mind this morning, ha ha, I have that gt1549 I got originally for this project. I could put them both on. Now I have just written that down it seems even more bananas, it's like a monsoon outside just now, no video weather, going to trawl eBay for ...

I got the plastics on today.

A bit less sleeper on the starboard side.
I advanced the ignition on the map where ...

One more thing it was as loud, very loud, and the AFRs was rich if anything. I'm wondering if the noise is a symptom of the over retarded ignition. I mean the ignition event is happening too late and the gasses are still burning in the exhaust. The exhaust and turbo does get very hot. I'll try ...

More things sorted today.
