Anyone know if Bill Blue is still making these kits? Anyone know of any other alternatives still available? All the info I’m finding is at least 4 years old.

 

there is a “Keng engine” in Thailand I found on FB. Not sure how legit, reliable it is tho.

 

l

thanks. I’ll check it out

 

Keng engine is legit, I just received my klx402 kit. Complete billet aluminum cylinder, ported cylinder head with oversized valves and high lift camshafts.

Keng engine 402 on the left vs stock 249cc Klx cylinder on the right.

 

He sure is. I installed his 351 kit and pumper carb over the winter. Total game changer.
Search for B and B cycle restoration.

 

Has Kenge got a water jacket on the cylinder separate from the head? How does it circulate?

 

I wondered the same thing. I saw pics of a cylinder without water jacket circulation passageways. I contacted him about purchasing his cams.

 

His cams are klx300r cams as far as I know. But anyway he sells them cheaper than you can find online.

 

That is one small hole for cooling? I would love a 402 but 351 will satisfy me for off road usage

 

402 would make a really cool supermoto.
